Designated use
The field bus module type SPC200-COM-PDP has been
designed for connecting the SPC200 to the PROFIBUS-
DP in accordance with EN50170 part 2. With this field bus
module, the SPC200 can be operated as a slave on the
PROFIBUS-DP. Maximum one field bus module may be
installed.
The basic components and modules for the SPC200
are described in the User Manual type P.BE-SPC200-...
You must observe at all costs the safety precautions
described therein as well as the designated use of the
individual components and modules. Please observe
also the notes on safety in the operating instructions for
the pneumatic components used. The SPC200 as well
as the modules and cables to be connected may only
be used as follows:
– as intended
– in their original state
– without any modifications
– in perfect technical condition
If used with additional commercially-available compo-
nents, such as sensors and actuators, the specified
limits for pressures, temperatures, electrical specifica-
tions, torques, etc. must be observed. Local and na-
tional technical regulations must also be observed.

SPC200-COM-PDP 9904NH 1-5

A system with the above-mentioned modules offers the
following scope of performance:
•control of up to two pneumatic axes.
•programming and diagnosis via a PC or an operating
panel.
•coordination with external PLC/IPC via a field bus.
With field bus module type SPC200-COM-PDP the
SPC200 can be connected to all DP masters.
The SPC200 can be controlled via the PROFIBUS-DP
in the operating modes start/stop or record selection.
The field bus module provides the address range re-
quired for this.

1.4 Operating modes
Whether for control via an I/O module or via a field bus,
the SPC200 offers the following operating modes for
processing the stored NC programs:
•start/stop mode
•record select mode
The desired operating mode can be set with the control
panel or with WinPISA. Detailed information on the
operating modes can be found in the user manual for
the SPC200.
The SPC200 communicates with the PROFIBUS mas-
ter via the internal I/O address ranges (internal
input/output addresses) of the field bus module. De-
pending on the operating mode used, field bus module
type SPC200-COM-PDP provides the following I/O bits
for communication with the DP master:
Operating mode I/O address range of field bus
module type SPC200-COM-PDP
Start/stop I10.0 - I13.15*)
Q10.0 - Q13.15*)
Record select I10.0 - I11.15*)
Q10.0 - Q10.15*)
*) Address specifications as seen by the SPC200

With the field bus module, 10 bits are available for se-
lecting the NC record number in record select mode.
The maximum permitted number of NC records (up to
1000) of the determined starting programs can there-
fore be accessed.
When a field bus module is used:
•the address ranges I0.0 ... I0.9 and Q0.0 ... Q0.7 re-
main unused. These address ranges, which serve
without field bus module for controlling the SPC200,
are not available.
•maximum 3 I/O modules can be inserted. These pro-
vide exclusively freely programmable I/Os in the
operating mode start/stop.
The address assignment when a field bus module is
used is shown in the table below.
