1 General
The direct key module is a module that can be used in conjunction
with a SIMATIC panel PC 670 and 870 with an integrated
membrane keyboard (referred to below as a "panel PC").
The direct key module is suitable for use with panel PCs,
• that are assembled as a unit or
• where the front panel and the PC box (see Figure 7–2) are
separate.
The direct key module has an interface for connection to an
external transfer module (see Chapter 10).
Figure 1–1 Direct key module with cable to panel PC
This module can be used to assign digital events to certain keys of
the membrane keyboard on the panel PC. This means that an SPS
digital input can be controlled by key operation. The module is
implemented as a PROFIBUS-slave – the data is therefore
downloaded thro a standard field bus.
General 06/01
1–2 Direct key module
A5E00100668B-01
The direct key module extends panel PC functionality as follows:
• Up to 32 keys of the panel PC membrane keyboard can be
queried by the PROFIBUS as direct keys.
• If required, up to 16 additional keys can be connected from an
external control panel.
• 16 digital outputs are available to drive the indicator lights (by
SPS via PROFIBUS-DP) in any external control panels that
exist.
• All the direct keys can be queried by SPS via PROFIBUS-DP.
• The PROFIBUS-DP interface is designed for baud rates of from
9.6 kBaud to 12 MBaud.
Note
The direct key module is suitable for use with the following panel
PC front versions:
– 10" display from version E
– 12" display from version E
– 15" display from version C
06/01 Description of functions
Direct key module 2–1
A5E00100668B-01
2 Description of functions
Usage
The direct key module is used to query keys via PROFIBUS-DP in
a defined cycle clock. The direct key module is therefore handled
on PROFIBUS-DP as a PROFIBUS standard slave.
Mode of operation
The direct key module always works on PROFIBUS-DP as a slave.
Activation or querying of the direct key module is always done thro
a DP master. The DP master addresses the direct key module via
layer 2 of the ISO reference model. Once the direct key module has
received a successful PROFIBUS message, it automatically
generates the requested response messages (under DIN E19245
T3). The organization for the digital inputs and outputs and the type
of data communication is fixed at the slave. Data communication to
and from the direct key module is always consistent (fixed).
As well as the keyboard query of 32 direct keys (assigned to the
digital inputs DI 0.0-0.7, DI 1.0-1.7, DI 4.0-4.7 and DI 5.0-5.7), the
PROFIBUS-DP gives you the option with this module of querying or
controlling 16 digital outputs (DO 0.0-0.7 and DO 1.0-1.7) with 24V /
100mA and 16 digital inputs (DI 2.0-2.7 and DI 3.0-3.7) with 24V
levels.
Once set, the PROFIBUS address (station address) is stored in the
direct key module and is retained even after the panel PC has been
switched off, or there has been a power failure.
Description of functions 06/01
2–2 Direct key module
A5E00100668B-01
Note
On delivery, the PROFIBUS address (station address) is set to 126.
Once it has been incorporated, the user can parameterize a direct
key module supplied in accordance with DP rules with the default
address 126 with the required address (node assignment). This
address setting is essential, as otherwise data cannot be
exchanged with the direct key module (by definition, DP stations
with the address 126 do not take part in a data exchange).
Address setting
The device must not be open for the address setting. The address
of the direct key module is set via the PROFIBUS. However, there
must be a device available with DP access software:
• ET200 hand-held device or
• PG/PC with MPI/DP interface or
• SIMATIC PC
The following software must be installed on the device:
• STEP 7 software (hardware config.) or
• COMPROFIBUS software.
For the address setting to be successful, a PROFIBUS-DP
connection must be established between the direct key module and
the device being used.
Attach the DP connector (9-pin sub D socket connector) of the
direct key module to the MPI/DP interface of the device on which
the DP access software is installed.
06/01 Description of functions
Direct key module 2–3
A5E00100668B-01
When using STEP 7 software, proceed as follows:
• Start SIMATIC Manager.
• In the SIMATIC Manager Target System menu, select the
Assign PROFIBUS Address function. The SIMATIC Manager
then gets in contact with the direct key module. A dialog box
displaying the currently set direct key module address appears,
in which you can enter a new address (1, 3-125).
• Set the required address.
• Exit SIMATIC Manager.
If you want to use other PROFIBUS configuring tools, you need the
device master file (GSD file). This is on the direct key module disk,
in the gsd folder.
Software
For system configuration, we recommend SIMATIC products (e.g.
STEP 7 software, COM PROFIBUS or COM LDP) or configuration
software from third-party suppliers.
To program the direct keys (S1-S16, F1-F20) on the panel PC, use
the KeyPad software tool. This tool allows you to change the key
codes of all the keys.
Installation
The KeyPad software tool is located in the keypad folder
• on the installation disk included with the direct key module, as
well as
• on the "Documentation & Drivers Panel PC 670/870" CD
accompanying every panel PC.

• In the folder that, according to the designation, is suitable for the
display size of the panel PC, open the keypad??.exe file. This
opens the following window.

• Mark the Directkey enable checkbox in the Normal mode and
Alpha mode fields, so that the direct key function is effective for
the selected key.
This calls a default digital input in the Direct key border, which
can be changed in accordance with the options in the list box.
The meaning of the colors is as follows:
– Green: Assigned to the set key
– Red: Assigned to another key
– Grey: Not used yet

Digital inputs DI 0.0-5.7 are defined as a block, on the basis of the
slave-controller module used (preset at the slave). The start
address for the block, on the other hand, can be chosen freely. The
block comprises the 32 direct keys of the SIMATIC PC membrane

Note
The values in the "Key on panel PC" column in Table 4–1 are the
default settings for the KeyPad software tool.
The direct key number is specified by keyboard controller
parameterization. Parameterization can be reprogrammed at any
time. After programming, the settings are saved in non-volatile
memory in the keyboard controller, i.e. they are retained even after
the power supply is switched off.

Direct key module installation
The following types of installation are possible for the direct key
module:
• DIN-rail mounting
• Cabinet mounting
Note
When installing the direct key module, please pay attention to the
length of the cable to the panel PC keyboard controller. This is
50 cm.
DIN-rail mounting
A mounting element for a 35mm DIN rail is already attached to the
direct key module.
Cabinet mounting
• Remove the mounting plate with the DIN rail from the direct key
module.
• Mark out the four screw holes in accordance with the drill
drawing below.

Cable mounting to the panel PC
First detach the PC box:
• At the back of the panel PC, remove a total of four screws from
the brackets (see Figure 7–2).
Caution
The weight of the PC box can cause the hinged clasp on the PC
box from the panel PC 870 to bend. Support the PC box as you
swivel it out (see Figure 7–2).
• Swivel the PC box out.
• Loosen the fixing devices on the connectors.
• Take out the connectors.

Appropriate EMC installation
The basis for trouble-free operation is appropriate EMC attachment
of the direct key module and the use of cables that are immune to
interference.
Caution
• Only shielded cables are acceptable for all signal links.
• All plug connectors must be screwed or fixed in position.
• Signal lines must not be run in the same cable pit as power
lines.
• Siemens AG cannot be held responsible in any way for
malfunctions and damage resulting from the use of homemade
cables or the cables of third-party manufacturers.
