PP7, PP17-I, PP17-II Equipment Manual
Release 06/98
Product Description
The Push Button Panels can be used to display the operating statuses of a
machine or system and to control processes.
Until now , keys and lamps had to be individually mounted, wired and tested
for this purpose. This was also a time-consuming process. In contrast to this,
installation of Push Button Panels requires only a rectangular cut-out and a bus
connection (DP or MPI). The standard configuration ensures that the panel is
ready to operate immediately after all the connections have been made. This
results in considerable advantages in respect of time compared to conventional
connections.
The Push Button Panels provide a lar ge variety of features which can be used
without the necessity of PLC programs:
 Short-stroke keys with surface illumination according to the LED colors
 Additional 24 V digital inputs and outputs
 All short-stroke keys and digital 24 V inputs can also be individually
configured as switches
 Integrated lamp and key test
 Central release input to lock all operating actions
 Integrated flash timing
Color -coding for LEDs, such as red, green, orange
 Pulse extension for short-stroke keys and digital 24 V inputs can be
specified via parameters
 Perforated cut-outs for 22.5 mm standard optional elements, such as
key-operated switch and emer gency shutdown switch
 OP design, can be set in rows, without gaps
The Push Button Panels have been conceived for installation in cabinets and
can be implemented in all situations where keys, switches and lamps are re -
quired.
The high degree of protection (IP65 on the front side) and the fact they are
maintenance-free make the Push Button Panels suitable for use even in rough
industrial environments.

The Push Button Panels can be operated using the following connections:
 via MPI to a SIMA TIC S7-200
 via MPI to a SIMA TIC S7-300
 via MPI to a SIMA TIC S7-400
 via PROFIBUS-DP to a SIMA TIC S5
 via PROFIBUS-DP to a SIMA TIC S7
 via PROFIBUS-DP as standard slave to a DP master from a dif ferent
manufacturer; possible restrictions regarding configuration of the Push
Button Panel.
Parameters in the Push Button Panels are predefined and the unit is thus imme -
diately ready to operate. V arious options can also be activated by adjusting
certain parameters. Each key , LED, digital input and output can be individually
adapted according to specific requirements.
No special configuration software is necessary for the Push Button Panel. All
adjustment of the settings is carried out either directly on the Push Button
Panel or by means of the PLC configuration software.
All adjustments to settings carried out on the Push Button Panel are stored in
its memory module. In cases where the unit electronics or the entire unit are
replaced, the interface need not be reconfigured. Only the old memory module
needs to be transferred to the new unit.

1.2 Operating and Display Elements
The Push Button Panels are all equipped with a keyboard containing short-
stroke keys. The individual keys can be configured in respect of their function
as either switches or keys.
Function momentary–contact switch:
The corresponding bit in the PLC is set as long as the
key is pressed.
Function switches: Pressing the key sets the corresponding bit, pressing
again resets it.
T wo LEDs are integrated in the keys and are used to display the bit status of
the connected PLC. The LEDs can indicate four dif ferent statuses, one of
which can be defined via parameters.
All the operating elements of the Push Button Panels are linked to bits in the
PLC. The keys on the Push Button Panel can be used to influence the bits in
the PLC and thus control the af fect of processes. At the same time, the LEDs
indicate the bit status of the PLC and, thus, the operating status of the process
being monitored.
When several keys are pressed simultaneously , it is detected by the Push But -
ton Panel and the bits are set in the PLC. After restarting the system following
a power failure, all the bits are set to 0.
Additional 22.5 mm elements can be connected using the digital inputs and
outputs. Non-connected digital inputs are automatically set to 0.
The release input serves to lock the Push Button Panel. A key-operated switch
can be connected here, for example. The release input permits switching be -
tween normal operation (open contact) and monitoring mode (closed contact).
In normal operation, all the functions on the Push Button Panel are available
for use, whereas in monitoring mode, the following restrictions are valid
 the inputs are locked, no signal exchanges are reported to the PLC,
 the last status of all the keys is maintained by the PLC until normal
operation returns.

following measures in normal operation:
 By pressing the key assigned to the Lamp/Key test function by the
corresponding parameter .
 By setting the two LED bits of the key assigned to the Lamp/Key test
function according to the configuration. The bits must be set in the PLC
using a relevant program.
The Lamp/Key test function is assigned to Key 1 (top right) in the pre-adjusted
system settings.

On activating the Lamp/Key test, the unit switches to the corresponding oper -
ating mode. In this case
 the ERROR LED blinks,
 the LEDs integrated in the Push Button Panel keyboard are activated,
 all the Push Button Panel digital outputs are set to 1.
After pressing any key when in operating mode Lamp/Key test,
 the LED/lamps go out for the period in which the key is pressed,
 all the Push Button Panel digital outputs are set to 1.
This is valid for the period in which the key is pressed. All the keys and digital
inputs can be tested in this way .
In order that no unwanted signals are transmitted to the PLC during the Lamp/
Key test, the following restrictions are valid in respect of Push Button Panel
operation:
 the inputs are locked and no signal exchanges are reported to the PLC,
 the last status of all the keys is maintained by the PLC until normal
operation returns.
The last key operation reported to the PLC is the pressing of the Lamp/Key test
button.
T o terminate the Lamp/Key test,
 release the corresponding key , or
 reset the corresponding bits in the PLC
The unit returns to normal operation and the restrictions regarding the Push
Button Panel operation are released.

2.2 Define Configuration in PLC
2.2.1 MPI connection
If connection type MPI is used for the Push Button Panel, no hardware config -
uration is necessary . Only the MPI address needs to be set on the Push Button
Panel.
Interrelated memory areas must be set up in the PLC for the keys, LEDs and
digital inputs and outputs. The following table indicates the length of the
memory areas to be set up for the various unit versions.
Memory ar ea PP7 PP17-I PP17-II
Keys 1 Byte 2 Bytes 4 Bytes
Digital inputs 1 Byte 2 Bytes 2 Bytes
LEDs 2 Bytes 4 Bytes 8 Bytes
Digital outputs – 4 Bytes 4 Bytes
Total 4 Bytes 12 Bytes 18 Bytes
In order to modify system settings, a data block must be created in the PLC
which contains the configuration data for the Push Button Panel. The structure
of this configuring data block is depicted in Chapter 2.4. The number of the
configuring data block must be specified when configuring the Push Button
Panel.
2.2.2 PROFIBUS-DP connection
When connection type PROFIBUS-DP is used, the Push Button Panel must be
installed in the PROFIBUS configuration software as a slave in the network. In
the case of SIMA TIC S5, the configuration software used is COM-PROFIBUS,
and for SIMA TIC S7 connection to the network is performed via HW -
CONFIG. The configuration software defines the following:
 station address,
 the I/O area used
 and the configuration of the buttons and LEDs.
Ensure that the same station address is specified that is set on the Push Button
Panel.
