C7-635 Control System

Interplay of CPU and TP/OP
The individual components integrated in the SIMATIC C7-635 correspond to the
components that can also be used for modular configurations consisting of
CPU-314C-2DP, TP170 B, and OP170 B.
The basic mode of operation is also similar to operation of a configuration with
standard modules from the programmable controller and TP/OP family; the
individual components function independently, and each processor has its own
dedicated memory.
The C7-CPU and the C7-TP/OP communicate internally over the MPI interface.
The C7-CPU is independent of the C7-TP/OP. The C7-TP/OP continues to run, for
example, if the C7-CPU enters the STOP mode.
Programming and Configuration
Note
The C7-CPU and the C7-TP/OP each have their own MPI address. Therefore, you
program and configure these components in exactly the same way as independent
CPU and TP/OP components.
These items are addressed explicitly in the manual, as necessary.
You program the C7-635 Touch with STEP 7 as of V 5.2 + Service Pack 1 +
Hardware Update C7-635 Touch V2.0.
You program the C7-635 Key with STEP 7 as of V 5.2 + Service Pack 1 +

Product Overview
2-6 C7-635 Control System
A5E00155581-04
CPU
The user program controlling the process runs on the C7-635.
The following functional units determine the mode of operation of the C7-635:
•Loading memory
The loading memory is located on the Micro Memory Card (MMC) and contains
the user program.
•Processor
The processor executes the program cyclically:
– At the beginning of the cycle, the processor reads the signal states on all
inputs and generates a process image of the inputs (PII).
– The program is executed step-by-step using internal counters, bit memory,
and timers.
– The processor stores the calculated signal states in the process output
image (POI). At the end of the cycle, the process image is transmitted to the
outputs.
Touch Panel/Operator Panel
The touch panel and the operator panel of the C7-635 are based on the standard
Windows CE operating system. You can visually display operating modes, current
process values, and faults. You can also make entries on the C7-635. Simple
machine diagnostic functions are also possible.
You can also incorporate your own graphics, digital pictures, and scanned images
into your project. Moreover, you can represent elements such as temperature
variations graphically using bar graphs and diagrams.

Installing and Wiring the C7-635
3.1 Labeling Strips (C7-635 Key only) Labeling Strips
The function keys can be labeled individually with labeling strips that are inserted in
the keyboard from below.
System-Specific Labeling
The template for the labeling strips is provided with ProTool (V6.0 + Service
Pack 2, directory Utilities) or can be obtained from the Internet. With it, you can
design and print out system-specific labeling strips easily.
Internet address: www.siemens.com/automation/service&support
The file “SLIDE635.DOC” with the labeling strips can be obtained by selecting
Product Support > Automation Systems > SIMATIC Industrial Automation Systems
> PLC > SIMATIC C7 > Control Systems > Downloads
To make your own labeling strips, use transparent film (0.1 to 0.15 mm thick) so
that the LEDs in the function keys remain visible. Label the film using either a
printer or a wipe-resistant foil pen.
!Caution
To prevent the keyboard from smudging on the inside, the labeling must be
covered with a transparent adhesive strip or a transparent adhesive film.
Otherwise, operating pressure causes the labeling color to rub off on the inside of
the key. A key that has been smudged from the inside cannot be cleaned and can
only be replaced at the factory.
The labeling strips have to be cut exactly along the indicated cutting edge. If the
labeling strip is cut too large, it cannot be inserted.

3.5 Guidelines for Fail-Safe Construction
Overview
Shielding measures must be implemented in an automation system to prevent
faults. This can only be ensured by use of an enclosed metal construction (cabinet
mounting, for example).
Low frequency (LF) or high frequency (HF) interference signals can reach the
internal bus of the controller if the system is not grounded or shielded properly,
causing a malfunction.
Interference signals can also be caused when relays or contactors switch (very
rapid changes in current or voltage; HF interference signals) or when two
components of system have different grounding potentials (LF interference
signals).
Note
You can find additional information about construction guidelines in the S7-300,
CPU 31xC and CPU 31x: Hardware and Installation manual.
Use/Installation of Fail-Safe Cables
•Only shielded cables are permitted for all analog signals.
•Cable shielding must be grounded on both sides for:
– Controller cables
– Bus cables
– I/O device cables
•Standard cables from Siemens comply with these requirements.
•All plug connections must be screwed or clamped into place.
•Signal lines must not be laid parallel to heavy current lines. A separate cable
channel must be used that is separated from heavy current lines by at least
50 cm.
Installing and Wiring the C7-635

C7-635 Control System
A5E00155581-04
Cabinet Design
Devices that could introduce interference signals from outside into the cabinet
must be placed far below the cabinet. The grounding terminal must be placed
immediately at the cabinet entrance to directly ground cables capable of carrying
interference signals. All shielded cables must be laid here with the shield. For
double-shielded signal lines, only the outer shield is to be laid here.
Long signal lines must be installed along the cabinet walls. It is important to use an
EMC-compliant cabinet construction to reduce disturbance variables. All chassis
ground connections in the cabinet are to be made with a large cable cross section
and laid over a large surface.
Analog devices located in the control cabinet must be isolated and grounded at a
point in the cabinet (use a copper strip).
The materials used should always contain the same type of metal (as a rule, do
not use aluminum due to the risk of oxidation).
All doors and plates (side walls, back wall, and ceiling) of the cabinet must be
connected at least three times with cabinet framework (short, unpainted
connections over a large surface).
Note
The following applies for systems that generate large amounts of
electrostaticenergy (such as textile machines and special construction machines):
The grounding conductors of the machine parts exposed to interference signals
are to be connected to a special functional ground separated from the central
grounding point of the cabinet (surface grounding with building construction,
sheathing).
Functional Ground
Connect the functional ground (see Figure 3-17) to the cabinet ground with a
cable lug and a cable with a minimum cross section of 4 mm2.

ground. A grounding terminal is used to connect the shield directly to the ground of
the C7-635.
Procedure
Proceed as follows to install the grounding terminal supplied with the C7-635 and
the shield terminals:
1. Mount the grounding busbar at the position shown in Fig. 3-17, using the
included screws 1 or, as an alternative, at this position 2.
2. Install the shielding terminals on the grounding busbar as shown in Fig. 3-17.
3. Push the stripped ends of the cable shielding into the shielding terminals.

3.7 Coding Connector Parts to Prevent Incorrect Usage
You can order a connector set with coding profiles and coding tabs as an
accessory for the C7-635 (see accessories in Section 2.2).
!Caution
It is highly recommended that you code the connectors, as unintentionally using
the wrong connector may damage the device.
Coding the Connectors
The coding profiles ➀ and coding tabs ➁ (see Figure 3-18) enable you to code
connectors without loss of pole to prevent incorrect usage. Use the following
procedure:
1. Insert coding profile ➀ on connector part ❶ into the slots provided.
2. Insert coding carrier ➁ on the main housing ❷ into the corresponding recesses.
A coding profile and a coding tab facing one another prevent the connector part
from being inserted.
If a coding profile and coding carrier do not face one another, the connector part
can be inserted without difficulty.

General reset
Performing a general reset of the C7-CPU (clearing the memory and
reloading the user program from the MMC) requires a special
operating mode key procedure:
1. Select STOP mode by pressing the DOWN key.
– The key LED “S” illuminates, and
– the CPU status LED “STOP” illuminates.
2. Select MRES mode by pressing the UP key and the DOWN key
at the same time. The “M” key LED illuminates.
3. Hold the keys down until the status LED “STOP” illuminates for
the second time and remains lit (this occurs after 3 seconds).
4. Now release the keys.
5. You must repeat pressing both keys within 3 seconds.
6. Release the keys when the ”STOP” status LED flashes rapidly
(at 2 Hz).
When the CPU has finished the general reset operation, the
“STOP” status LED stops flashing and remains lit. The CPU is
now reset and in STOP mode.
The operator actions described in the table above are only required if:
•The user wants to perform a general reset of the C7-635 without the C7-635
itself giving a general reset prompt (indicated by slow flashing of the “STOP”
status LED).
•The C7-635 requests a general reset itself, pressing both keys briefly is
sufficient to start the general reset process.
If the C7-635 requests a new general reset after a general reset operation has
been performed, the MMC may require formatting in certain cases. You will find
information on this subject in the S7-300, CPU 31xC and CPU 31x: Hardware and
Installation manual.
If the group error (SF) display is illuminated on the C7-635, its diagnostic buffer
has to be evaluated with the programming device/PC. More information about the
entries in the diagnostic buffer is provided in the STEP 7 Online Help.

5.2 Replacing the C7-635
Introduction
A C7-635 is not designed for onsite repair. Therefore, a defective C7-635 must be
replaced.
To save the configuration of the TP/OP, you should have a Compact Flash Card
(CF Card). You should make a backup of the configuration on the CF card as soon
as you have finished commissioning the device, so that you can restore the
configuration if the device becomes defective.
!Caution
Prior to installing and uninstalling the device, remove the Micro Memory Card
(MMC) of the CPU and the Compact Flash Card (CF Card) of the TP/OP.
The inserted CF card protrudes from the C7-635 and could therefore be damaged.
How you proceed depends on whether you have backed up the TP/OP
configuration on a CF Card.

•contained in STEP7 V5.4 Service Pack 1
•configurable with the older STEP7 versions:
The C7 devices with the new order number can be downloaded from the Internet as
a hardware update (0109).
Requirement is STEP7 V5.2, Service Pack1.
•configurable with the corresponding previous C7 devices
•compatible with the previous C7 devices
Non--retentive data blocks
In opposition to the data in the S7--300, CPU 31xC and CPU 31x manual, Technical
data”, chapter 4.1.2, the C7 devices with frimware V2.0.12 are no longer supported by
retentive data blocks. Non--retentive data blocks and code blocks can be loaded to the
maximum limit of the working memory. Retentive data blocks can be loaded to the
maximum retentive limit of the working memory (see the following table).
