SIEMENS Warning Risks involved in the use of so-called SIMATIC-compatible modules of non-Siemens ma-nufacture "The manufacturer of a product (SIMATIC in this case) is under the general obligation to give warning of possible risks attached to his product. This obligation has been extended in recent court rulings to include parts supplied by other vendors. Accordingly, the manufacturer is obliged to observe and recognize such hazards as may arise when a product is combined with products of other manufacture. For this reason, we feel obliged to warn our customers who use SIMATIC products not to install so-called SIMATIC-compatible modules of other manufacture in the form of replacement or add-on modules in SIMATIC systems. Our products undergo a strict quality assurance procedure. We have no knowledge as to whether outside manufacturers of so-called SIMATIC-compatible modules have any quality assurance at all or one that is nearly equivalent to ours. These so-called SIMATIC- compatible modules are not marketed in agreement with Siemens; we have never recommended the use of so- called SIMATIC- compatible modules of other manufacture. The advertising of these other manufacturers for so-called SIMATIC-compatible modules wrongly creates the impression that the subject advertised in periodicals, catalogues or at exhibitions had been agreed to by us. Where so-called SIMATIC- compatible modules of non-Siemens manufacture are combined with our SIMATIC automation systems, we have a case of our product being used contrary to recommendations. Because of the variety of applications of our SIMATIC automation systems and the large number of these products marketed worldwide, we cannot give a concrete description specifically analyzing the hazards created by these so-called SIMATIC- compatible modules. It is beyond the manufacturer's capabilities to have all these so-called SIMATIC-compatible modules checked for their effect on our SIMATIC products. If the use of so-called SIMATIC- compatible modules leads to defects in a SIMATIC automation system, no warranty for such systems will be given by Siemens. In the event of product liability damages due to the use of so-called SIMATIC-compatible modules, Siemens is not liable since we took timely action in warning users of the potential hazards involved in so-called SIMATIC- compatible modules.

The submodule in its full configuration has eight quick analog input channels with max. 35 psec. conversion time, four input channels with analog value conditioning and four analog output channels. Two comparators allow the comparison of analog values with each other and via two value difference amplifiers, the signals can be amplified up to 20 times their original strength. All analog signals can be freely jumpered via soldering bases on the circuit board. This means that as a user you can decide about the individual combinations of the available hardware components. Furthermore, eight digital inputs and eight outputs with direct bus access are available. Customer-specific interrupt processing can be effected by means of the jumpering base. The 1P 243 submodule can be used for the following programmable controllers: - - - - S5-115U/H S5-135U s5-150s/u S5-155U/H or expansion units (see section 6.1). For the programmable S5-115U, an adapter casing is required. No fan assembly is required. 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 1-1 Mechanical Construction R02192 2 Mechanical Construction 2.1 Dimensions and Mechanical Data The 1P 243 is a printed circuit board in double European format, with dimensions of 233.4 mm x 160 mm (DIN 41494).

An analog eight-channel multiplexer is connected on the input side of the converter. The conversion of the analog input values takes place in three stages: 1) Select the channel 2) Output the conversion command 3) Read the result 1) Select the channel: The multiplexer is addressed under the module address +7. The channel to be converted (O to 7) is selected by writing the three data bits 2, 21, and 22. Channel selection: (in the byte module address +7) DO D7 LOG STR I x x 1 x 2 2 2 ' 2 1 If the same channel is read in several times in sequence, it need not be selected each time. In such a case it suffices when the active values are converted and read out. The selected channel remains current until a different channel number is written. The current channel selected by the program is indicated by the three yellow LEDs on the module front plate. 2) Output the conversion command: The conversion command is given by writing the module address +6, whereby the written data is irrelevant. 3) Read the result: The result can be read immediately in the peripheral word module address +6 as the "Ready" signal is only generated when the ADC has completed the conversion (i.e., after a maximum of 35 psec.). No additional waiting time is required. It is also possible to process other parts of the user program within the 35 psec. period. 3 - 4 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 Function Description R 02/92 3.3.3 Input Circuitry At the pins AR1 to AR8 of the analog signal jumping block, the analog input AIO to A17 can be not only active, but they can also be switched to the inputs of the analog-value conditioning circuit or to the outputs of the difference amplifiers.

It is possible to output analog values (provided by the D/A converters) on a certain channel, and transfer this signal simultaneously to different outputs. In the same way, for instance, the outputs of the difference amplifiers (P controllers) or conditioned analog values can be directly output as analog values. Attention must be paid to the input side of the analog output A05 to make sure that an analog amplifier is connected. It is not only able to amplify the value provided by DAC3, but also a value which, via an analog input, is present as an actual-value conditioning input on the P controller. Three digital/analog converters, which are described in more detail below, convert binary values into analog signals. 3.4.2 Digital/Analog Converters 1 and 2 3.4.2.1 Rated Output Range and Resolution Digital/analog converters DAC1 and DAC2 are systems independent from each other. The resolution is 11 bits plus sign. Bipolar analog values in the range of *1 O V can be output. 3.4.2.2 Writing the Analog Outputs DAC1 is addressed under the module address +0 and DAC2 under the module address +2. The binary value should be transferred to DAC1/2 by a word statement to prevent possible peaks during byte-wise write procedures.

The 12th bit is cutoff and written separately as sign bit at position 2 15. The highest representable value FFFH, at a resolution of 12 bits, corresponds to the maximum voltage +20 V, but it is adapted to the output voltage range and is converted to the negative voltage -10 V.

For this purpose the sign bit 215 must at first be saved, then the bit pattern must be inverted (command CFW) and the sign bit must be written back.

This is necessary because the converter is not permanently "short-circuit proof" and the short circuit current is not defined. It is possible, however, to route signals other than those of DAC3 to the output amplifier, via analog-signal jumpering. The voltage booster has a 1:1 amplification. 3.4.4.2 Circuitry The analog output amplifier has the following circuitry: Analog-signal jumpering 1 AR29 22 k!il I I - m AA5 + F Front connector 3 - 10 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 Function Description R 02/92 3.5 Analog Value Conditioning Circuit 3.5.1 Operating Elements The four inputs of the analog value conditioning circuits are meant to standardize the voltages provided by encoders to the O V to +10 V range, and are conditioned in accordance with the setting of the trimming potentiometer on the module front plate. Conversion in the O to +10 V range is not possible unless input voltage > -4 V. Conditioning is always necessary when negative voltages are processed and routed via the comparators. The comparators are designed for positive voltages so that the input voltages must be transformed to the positive range. In addition to the 4 trimming potentiometers for setting the amplification and the offset, there are four measuring sockets on the front plate via which the conditioned analog values can be scanned. A socket (socket 6) is also available. This socket is connected to analog ground Maria. This socket can be used as the ground connection for a graphic recorder which records the conditioned analog signals. Attention: Socket5 hasnofixed internal connection toaspecificsignal. Itis located on the analog-signal jumpering space AR32. This socket is free for switching, either for a signal from an 1P 243. The conditional socket (i.e., the component routed to the soldering base) or for another external sig- 3.5.2 Functioning On the front plate of the 1P 243 there is one trimming potentiometer per input (AV1 to AV4) for the offset of the operation point by a binary amount between -2 V and +2 V and for setting the amplification (gain) as a factor in the range from 1 to 10. First, the active analog value is multiplied by the fixed factor 0.5 specified by the module. Then, the set offset is added, and finally this value is multiplied by the desired gain factor. The possible total gain is between 0.5 and 5. 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 3 - 11 R 02/92 Function Description The following block diagram shows the operating method of the analog value conditioning circuit: O crating point o#set -2 v to +2 v Front connector AVI to AV4 m Input time constant IL Multiplication constsnt - Gain setting + x 1 to 10 Y * Analog signal jumpering AR13 toAR16 XO.5 T SpprOX, 0.1 msec. n Measuring socket 1 to 4 Analog value conditioning Example: An input voltage which can vary in the range from -1 V to -1.5 V is to be compared in terms of hardware with an input voltage from -0.5 V to -2 V.

If negative input voltages need to be compared, they must be routed through the analog value conditioning circuit and converted to a positive value. The inputs of the comparators are connected with analog-signal jumpering via a filter circuit (AR17 to AR20). Depending on the application, the comparator inputs can be connected with two signals each that are routed through the soldering base. Via gating logic, the current comparator status can be read in, and/or an interrupt can be generated. In case of interrupt processing, be aware that a hardware interrupt, fed directly from the module to the bus, can only be processed by the controllers S5-115U/H and S5-135U with CPU 922 or CPU 928AJB.

Read module address +5 DO D7 1 1 1 1 D c B A Byte module address +7 not only specifies the analog input channel which is to be converted by the ADC, but also specifies the status of the signals LOG and STROBE. The bit LOG switches the gating logic from rising to falling edge, while STROBE locks or releases an interrupt. 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 898-0KF21 3 - 15 R 02/92 Function Description Write to module address +7 DO D7 LOG STR x x x TT IL 2 2 2' 4 2 ~ ADC channel selection at multiplexer STROBE for comparator gating logic interrupt, signal STR O = locked, 1 = released I Changeover of gating logic, signal LOG O = rising edge of comparator output, 1 = falling edge of comparator output The default status of the STROBE signal is"1". Attention: The signals LOG and STROBE must be allocated together for both comparators. Separate addressing is not possible. 3.6.4 Evaluation of the Comparator States 3.6.4.1 Representation of Comparator States As already mentioned in section 3.6.3., information about current comparator status is read in byte module address +5.

A clear definition of the status of the comparators and gating logic is dependent on the evaluation of "bits" A, B, C, and D. The easiest way to evaluate the "bits" is to apply the conditions necessary to make the status of one "bit" (i.e., either A or B, or C or D) equal to "O".

The desired amplification is set via the trimming potentiometer. For each of the two P controllers, one trimming potentiometer is available on the module front plate, and amplification factors from 1.1 to 20 can beset. The difference between the input voltages applied at P+ and P- is amplified. 3.7.2 Input Circuitry Since the two P controllers are built as device amplifiers, both input values have the same polarity.

Again, the respective output of the P controller can be either applied to the digital/analog converter or to the comparators, or it can immediately be used as an analog output. The output signal range of the difference amplifiers is within +1 O V. 3 - 20 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 Interrupt Processing R02/92 4 Interrupt Processing 4.1 General Conditions for Interrupt Processing This section now covers specific characteristics of interrupt processing in relation to the individual programmable controllers. Interrupt jumpering on the 1P 243 is described in section 5.7. An interrupt can only be triggered by the comparators or the gating logic on the output side. The condition for generating an interrupt is its enable by the signal STROBE. The corresponding parameter assignment is described in section 3.6, as well as a description of the switching of gating logic between rising edge and falling edge (signal LOG). This makes alarm processing only possible when the 1P 243-lAA.. module is fully configured. 4.2 Possibilities for Interrupt Processing In principle, interrupts can be evaluated in any programmable controller which allows operation with the 1P 243. In practice, however, this evaluation depends on the type of controller. Only with the S5-115U/H and S5-135U with CPU 928A/B or with CPU 922, is direct access to the bus with interrupt lines possible. For all other programmable controllers, a separate digital input module with interrupt-generating capability must be used. This module must be externally wired with the binary outputs of the 1P 243. 4.3 Direct Bus Access Direct access to the interrupt lines is only possible for programmable controllers with edge- triggering. This means that the central unit reacts only to edge changes without regard to specific status levels. This applies to allCPUSoftheS5-115U/H series, CPU 922 and the 928NB CPUS of the S5-135U series. If interrupts are triggered via direct bus access, the memory latch D9 may D@ be exchanged for the soldering base D9, included with delivery. 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 4-1 R 02/92 Interrupt Processing 4.3.1 Interrupt Processing in the S5-l15U/H In the S5-115U with CPU 941A, interrupt lines ~Aand ~B are available for CPU 941B, 942-7UH.... From CPU 942A/B on, the four interrupt lines-~~, ~B, ~? and ~Don, which interrupts can be initiated, are available. The two pins IRF and ~Gon the interrupt-jumper~g block X19may not be used; they must always be grounded on M (pin 6). The same applies to IRC and ~Dwhen CPU 941A is installed. Furthermore, all process interrupts which are not used must be connected to grounding M. An organization block is allocated to each interrupt in the S5-1 15U. The organization block must be programmed for interrupt evaluation. The following relations apply: Interrupt Interrupt Interrupt Interrupt ~% ~B ~C ~D - - - - OB OB OB OB 2 3 4 5 Each interrupt line should be allocated to only one interrupt-generating 1P 243. In the case of several accessing modules, it would require considerable software effort to determine which 1P 243 triggered an interrupt (no evaluation possible via peripheral byte O!). Attention; Interrupt requests can be processed only in the central unit. The interru t program structure and interrupt-OB handling are found in the ~5-115U manual or the S5-115H manual. Exception: Alarm processing in the expansion device is possible with EG 701 -3 (from release 6ES5 701-31A13) or EG 186U, when Iigth wave conductor interfaces 6ES5307-3UA1 1 and 6ES5 317-3UA11 are used. II Example: The two analog input channels AlO and All are compared with each other by comparator 1 (AIOto +Comp. and All to -Comp.). As soon as All exceeds the value of AIO, this is indicated by a signal light connected to the binary output B02 of the 1P 243. At the same time channel A13 is read in once in the interrupt program. The module starting address is given as 144, and interrupt line ~Bisselected.

The +comp. of comparator 2 is connected with A12 which is compared with a user-specified value (KF = +5000). As soon as the two analog input channel values exceed the correlated "setpoints", an interrupt is generated. In case of an interrupt from gating logic 1, AV1 is read in at the ADC of CPU 922 and a check is made to see ifthe value exceeds KF = + 3000. If so, an output is set. If gating logic 2 reports an interrupt, the binary inputs B13 to B15 of the IP 243 are read into CPU 928A/B. As soon as one of the inputs has the signal"1", the output byte 4 is overwritten with OOFFH.

The CPUS of systems S5-135U (CPU 922 and CPU 928A/B when parameterized accordingly) and S5-155WH oPerate in level-triggered mode. For devices without interrupt lines, the interrupt scan is made via the input byte O. This applies to the S5-150S and S5-150U controllers. If interrupt processing is desired for one of the aforementioned systems, replace the memory latch D9 on the 1P 243 with the soldering base D9, included with delivery. In addition an interrupt module is required. 4.4.1 Interrupt Processing in the S5-135U In the S5-135U programmable controller, both CPU 922 and CPU 928A/B operate in level- triggered mode. The CPUS, however, can also be parameterized for edge-triggered processing. In case of level-triggered operation, the digital input module6ES5432-4UA11 must be additionally inserted. On the 1P 243 module, the comparator outputs and the interrupt-generating outputs of the gating logic must be jumper-connected to the soldering base D9, which in turn is connected with the binary outputs of the 1P 243. Furthermore, the jumper connections on the soldering base X19 (pins 11, 12, 13, 14, 15 and 16 connected to grounding M, pin 6) may not be changed from their original delivery condition. Then the binary outputs are externally connected to the inputs of the interrupt module. The interrupt triggering is handled exclusively by the module 6ES5432-4UA1 1. A description is found in the appropriate equipment manual. When working with a separate interrupt input module, the 1P 243 can operate from any 1P slot, whether in the central unit or in an expan- sion unit. The interrupt module 6ES5432-4UA1 1, however, must always be inserted in the central unit. Several interrupts from one 1P 243 or from different IPs 243 can be routed to a digital module with the capability of process interrupt generation. Example: In the S5-135U with CPU 922the two analog input values AIOand All are applied tothe difference amplifier. The amplifier output runs to +comp. and is compared with -comp. which is connected to the input A16. If the value at the A16 channel exceeds the output voltage at the difference amplifier, an interrupt is generated and a value which was previously filed in FW 120 is output at A02 via DAC2. The module address is given as 160; parameterization is for falling edge. 4 - 12 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 Interrupt Processing R 02/92 Analog signal jumpering: Elm 7T3- m M ana Socket 6 Socket 5 Socket 4 Socket 3 Socket 2 Socket 1 Pin Signal 20 + 15 v 21 - 15 v 23 M ma AV1 24 AV1 AV2 25 AV2 AV3 26 AV3 AV4 27 AV4 ~: 28 AO1 29 A02 4 30 A03 * 31 A04 Analog * a output 32 A05 amplifier 33 M ma 10923 1211242019 1718 31 32 16 15 Solderin base 14 X2W?32 13L `: 25 26 27 28 21 22 29 r 1 23 45678 30 P I'-El DAC1 12 bits DAC2 12 bits - DAC3 8 bits " Multiplexer 34 AIO 35 AH 36 A12 37 A13 38 A14 39 A15 40 A16 41 A17 Diff. amp. = Comp. = Chan. = 1P 243 Equipment Manual @.SiernensA(31989, Order * * D w v w T * Chan.

In this case an interrupt signal is only possible via evaluation of the peripheral byte O. For details of this procedure seethe appropriate equipment manual. An interrupt OB is allocated to each bit of the input byte O, as follows: 10.0 10.1 10.2 10.3 10.4 10.5 10.6 10.7 - OB 2 - OB3 - OB 4 - OB 5 - OB 6 - OB 7 - OB 8 - OB 9 In case of a signal change for a bit of IBO, a branch to the correlated interrupt block takes place. Generally an interrupt module is used for interrupt generating (for the S5- 150U this is the module 6ES5432-4UA1 1, and for the S5- 150S it is the module6ES5432-3BA11 ). See the appropriate equipment manual for specifications and operation. On the 1P 243 itself, the memory latch D9 must be replaced by the soldering base D9. The interrupt-generating outputs of the gating logic are connected with the binary outputs BOO to B07 via the soldering base D9. Then the outputs are externally connected with the inputs of a binary input. The solder connections on soldering base Xl 9 remain in their original delivery state (all interrupt lines to grounding M). Attention: With the systems S5-150U/S, interrupt processing is only possible in an expansion rack. The same applies to the use of IPs. All interrupt-generating modules must be located in the same expansion rack. Example: In theS5-150U an 1P 243 is operated under the following conditions: A value stored in EJ!Y 78 is output on DAC2 and stored on the difference amplifier. Difference + is connected with AV3. The amplifier output value is compared with the analog input channel A15 at comparator 1, whereby A15 is also read in on ADC. If A15 is less than the value of the signal at +comp, A12 is first converted three times, then AV4 twice on the ADC. The module address is given as 240; parameterization is for rising edge.A6ES5432-4UA11 interrupt module is used and parameterized accordingly. 4 - 16 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 Interrupt Processing R 02/92 Analog signal jumpering: M ma Socket 6 Socket 5 ., Socket 4 Socket 3 Socket 2 1109231211 ?4 2019 Socket 1 Pin Signal 31 20 + 15 v 21 - 15V 32 23 M,m 16 AV1 24 AV1 AV2 15 25 AV2 AV3 14 A 26 AV3 AV4 27 AV4 ~: 13 28 AO1 25 718 21 1 r L2 Solderin base X291X f/2 3C 1I 12345678 Hffwf 34 AlO 35A11 36A12 37 A13 38 A14 39 A15 40 A16 41 A17 Diff. amp. = Comp. = Chan. = U(J DAC3 8 bits Multiplexer Chan.

The S5-155U system offers the additional possibility of interrupt requests via interrupt lines, but it cannot be put to use directly in connection with the 1P 243, as the hardware interrupts operate in level-triggered mode.

Indirect operation via the interrupt lines is possible, if the parameters in DX O were assigned accordingly. This is only possible with an interrupt-capable, digital-input module to which the desired 1P 243 signals are routed externally. The blocks OB 2 to OB 5 are defined as interrupt blocks (S5-150U/S mode). If interrupt evaluation in this manner is desired, see the S5-155U or S5-155H equipment manual. The evaluation of the input byte O is accomplished in the same way as in theS5- 150U/S systems; for each bit of input byte O, an interrupt OB is allocated where the respective interrupt reaction is filed. A process interrupt is always initiated by a binary input (e.g., from the interrupt module 6ES5 432-4UA11. Again, this input is set by one of the binary outputs of the 1P 243. On the 1P 243, the memory latch D9 must be exchanged for the soldering base D9 (included with delivery), which serves as a connecting link between the binary signal/interrupt jumpering and the binary outputs. The jumpers between the interrupt-line pins and the grounding contact M may not be altered from their factory-delivered condition. Attention: Operation of the 1P 243 and of the interrupt module 432-4 is possible in the central or expansion rack. The 1P 243 and the interrupt module can also be located in different module racks. Example: In the S5- 155U system, the difference amplifier 2 of an 1P 243 is connected to a conditioned analog value AV1 and to the analog input channel A15. The output of the difference amplifier is checked for exceeding or dropping below certain values. If the output exceeds a value furnished by DAC2, previously filed in FW 190, then the output of the difference amplifier and the inputchannel AV1 are read in at the ADC and stored in the flag area. Depending on the signal status of the binary input B12, either KF = +800 (status "O") or KF = +1000 (status "l") is active at DAC1. If the respective value drops too low, a voltage of 5.85 V is output at DAC3. The module address is given as 176; parameterization is for falling edge. On the module 432-4, the presetting must be set according to the operating instructions.

Furthermore, the binary inputs and the comparator outputs can be read with this function block. Prior to reading the comparator outputs, the gating logic is switched over.

Depending on the channel number, the function block reads an analog value from the module and outputs it at parameter ADC. The representation of the analog value depends on the NORM parameter: NORM = "O": The analog value read at the module is output unchanged at parameterADC (as a bit pattern according to the description in the operating instructions). NORM = "1" The analog value read at the module is converted to the nominal range. The nominal range is defined by the values at parameter BT The conversion formulas are: for BT = O (Nominal range O V to 10 V): 20000 ADC = rough value x ~192 for BT = 1 (Nominal range -10 Vto +10 V): 20000 ADC = rough value x ~096 for BT = 2 (Nominal range -5 V to +5 V): 20000 ADC = rough value x ~192 The analog value is output as a 16-bit fixed-point numeral for the unit mv. When parameter DE-L has the signal status"1", the binary module inputs are read and then output at parameter DE. If the module has no binary inputs, signal status "O" is output to all bits. When parameter KP-L has the signal status"1", the comparator outputs of the module are read and then output at parameter KOMI? The bits now required, LOG and STR, are set in accordance with the parameters LOG and STR, and they are transferred to the module during channel selection. 7-6 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 Programming Instructions R 02/92 Function Block FB 161 (PER:ANS) 7.3 7.3.1 Function Description The function block "Write analog module" either transfers a specified bit pattern or a 16-bit fixed-point numeral, standardized to the nominal value, to the module.

The value at parameter DAU is transferred to DAC1, DAC2, or DAC3 according to the channel number. The representation of the analog value DAC depends on the signal status at parameter NORM: NORM = "O": The bit pattern at parameter DAC (in the case of channel 3, the left byte) is transferred to the module unchanged (bit assignment as shown in the operating instructions). NORM = "1": The value at the parameter is interpreted as a standardized 16-bit fixed-point number (nominal range with KN = 1 or 2: * 10000 mV; with KN = 3: O to 10000 rev). Depending on the channel number KN, the analog value is computed according to the following formula: For channel number 1 or 2: 13422 A n a l o g v a l u e = DAC x -- 65536 For channel number 3: 1678 A n a l o g v a l u e = DAC x -- 65536 If the value is outside the currently valid nominal range, it is limited to an extreme value. If the parameter DA-S has signal status"1", the value at parameter DA is transferred to the binary module outputs. If the module has no binary outputs, the command is ineffective. 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 7 - 11 R 02/92 Programming Instructions This example shows the operation of the analog module 1P 243. By means of a simulator the individual functions can be selected (via binary inputs). The signal states can be displayed via binary outputs. The display shows how an analog value applied to the module can be read and how an analog value can be output via the module. This example also shows the necessary jumper settings and wiring requirements for the mo-dule. Therefore, it can also be used as a test program to check the jumper settings and functions of the module. 7.4.1 Device Configuration For a test of the analog module 1P 243, the following devices can be used: - One of the listed programmable controllers - Programmer (e.g., PG 750) - Analog module 1P 243 (6ES5 243-lAA11) in full configuration: front connector K with screw mounting (6)(X3 081) - Digital input module; front connector with screw mounting - Digital output module; front connector with screw mounting - 2 simulators (6ES5788-0L412) - Voltage source for two analog signals - Voltmeter 7 - 12 1P 243 Equipment Manual @ .%31W31S AG 1989, Order No: 6ES5 998-0KF21 R 02/92 Programming Instructions 7.4.2 Jumper Assignment of the Analog Module Module Address (Basic Address 160): DIP switch S2: 18 17 16 ABD 5 ON Jumper 3-16 = 25 = 3 2 ABD 7 ON [Jumper 5-14I = 27 =128 Module address z 15 14 13 12 11 10 x2 1 2 3 4 5 6 7 8 9 Analog routing: Soldering bases X32 and X29: Analog value 1 (PIN 16) -> Channel O -> (PIN 2) Comparator 1 + (PIN 20) Analog value 2 (PIN 15) -> Channel 1 -> (PIN 2) Comparator 1 - (PIN 19) DAC1 (PIN 21) -> AQ1 (PIN 25) DAC2 (PIN 22) -> AQ2 (PIN 26) DAC3 (PIN 30) -> AQ3 (PIN 27) 1P 243 Equipment Manual @ .%311WflS AG 1989, Order No: 6ES5 998-0KF21 7 - 13 R 02/92 Programming Instructions 7.4.3 Assignment of the Inputs and Outputs The program is designed in a way that allows easy adaptation to different input and output assignments. The program block (PB 243) that contains the test program works with flags only. The inputs and outputs to be used are allocated to these flags by organization block OB 1. In the example the flags are the input word IW4 and the output word QW4 or the input word IW4 and the output word QW8 for theS5-115U.

During start-up there is no need to supply any data to the analog module. Its ready state is indicated by the green LED on the front panel. The LED lights up when an external 24 V voltage is applied. If at the time the programmable controller is turned on, all simulator inputs are in switch position "O", no outputs maybe set after the start-up of the programmable controller. If one of the outputs Q 6. O/Q 10.0 (flag F 14.0) or Q 6.1/Q 10.1 (flag F 14.1) is set, a para-meterization error was made. The exact error cause can be identified at flag byte FY 16 (for the parameterization error shown for output Q 6. O/Q 10.0) or at flag byte FY 17 (for the parametrization error shown for output Q 6.1/Q 10.1). Both flag bytes are set in accordance with the error bytes FY 255 of the standard function blocks FB 160 and FB 161. 7.4.5 Reading the Binary Inputs If input 14.1 is brought to switch position"1", the binary inputs connected to the analog module are displayed at output byte QB4/QB8. If the signal status of these inputs is modified, the display on the simulator is modified accordingly. 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 7 - 15 R 02/92 Programming Instructions 7.4.6 Reading the Analog Value The channel numbers from O to 7 are specified via the parameter BGKN of function block FB 160. The LEDs on the module's front plate indicate the currently selected channel as a bit pattern. The analog value read in the example is transferred to the module through the front panel connector via input IW1 (contact 24) and the appropriate potential contact (contact 23). It can be measured simultaneously at sockets 1 (IW1) and 6 (ManJ. The output for analog value acquisition AV1 (Pin 16) must be brought to channel O of the ADC (Pin 1) via analog value jumpering. The analog value read by function block FB 160 is output in flag word FW 10. Via the programmer function "Control Variable", the actual value can be displayed directly. If input 14.0 ("NORM") is brought to switch position"1", the analog value is displayed in mV given in binary code (ranging from -1 0000 to +10000). Othetwise it is given as a bit pattern, the way it arrives from the module. Via the two potentiometers "Work point AV1" and "Amplification AV1", the analog value can be changed. In order to check whether the module reproduces the applied value in correct form, the amplification should be set to value"1" and the work point to "O". For this purpose a firm value (e.g., 2 V) should be specified at the analog value input AV1. Then a reading should be taken at the sockets and the amplification changed until the input value matches the end value. The work point is set by zero adjustment (i.e., the applied and the measured voltages are both zero). Via soldered jumpers the individual voltage ranges can be set as follows: UNI - 10V (BT = O: Voltage range from O V to 10 V) BI - 20 V (BT = 1: Voltage range from -10 Vto +10 V) BI - 10V (BT = 2: Voltage range from -5 V to +5 V) 7 - 16 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 Programming Instructions R 02/92 7.4.7 Checking the Comparators lf routing of analog values has not been completed, the output for analog value acquisition AV1 (Pin 16) must be connected with the "+" input of comparator 1 (Pin 20). Furthermore, the output for analog value acquisition AV2 (Pin 15) must be connected with channel 1 of the ADC (Pin 2) and with the "-" input of comparator 1 (Pin 19). Channel O is set to 2 V. Depending on whether the analog value measured at channel 1 is below or above 2 V, there will be different states of the comparator outputs (in this case A and B for comparator output 1). The function KP-L "Read comparator outputs" is switched on via input 14.2. Depending on the status of the LOG bit (I 4.3), the following signal states will result for comparator output 1: LOG (1 4.3) Channel 1<2 V Channel 1>2 V I I I = " 1" = " o" A = "O", B = "1" A = "l", B = "1" I I A = "1"j B = "l" A = "1", B = "O" The comparator outputs are conducted to the output byte QB5/QB9 and are displayed there. In this case "A" corresponds to output Q 5. O/Q 9.0 and "B" corresponds to Q 5.1/Q 9.1. After turning off the function "Read comparator outputs", the outputs at the simulator remain active. Via input I 4.7 (flag F 4.7) the outputs can be reset. 7.4.8 Writing the Binary Outputs When the function "DA-S Write binaty outputs" (1 4.6) is activated, the binary outputs of the analog module, connected to the simulator, are indicated by LEDs on the simulator. The binary outputs are entered at input byte IB5. 1P 243 Equipment Manual @ Siemens AG 1989, Order No: 6ES5 998-0KF21 7 - 17 R 02/92 Programming Instructions 7.4.9 Writing the Analog Value When the analog routing operations have been performed in single steps so far, they now must be supplemented by the following jumpers: DAC1 (PIN 21) -> AOI (PIN 25) DAC2 (PIN 22) -> A02 (PIN 26) DAC3 (PIN 23) -> A03 (PIN 27) Via the programmer function "Control variable" a value can be specified via flag word FW 12 which is output as an analog value. If input 14.0 (NORM) has signal status"1", the value can be output in mV in binary form (ranging from -1 0000 to +10000). Otherwise the bit pattern is required and is then directly transferred to the module. In order to determine the written analog value, it is measured at the contacts in the front connector of the analog module (e.g., pin 28 for AO1 and pin 33 for potential). 7 - 18 1P 243 Equipment Manual @.SiemensA(31989, Order No: 6E.S5998-0KF21 Programming Instructions R 02/92 I 7.5 Programming Without FB k 7.5.1 Address Assignment For read and write operations the 1P 243 requires an 8-byte address area.

Attention: Not only the channel, which is selected by the multiplexer and then converted by the ADC, is stored in byte "subaddress 7" but also the desired states of the "LOG" and "STROBE" bits. When writing the data, make sure that no other functions are overwritten. 7 - 20 1P 243 Equipment Manual @ siWfW3flS AG 1989, Order No: 6ES5 998-0KF21
