Option: Deployment PROFIBUS communication
8.1 Fast introduction
For the PROFIBUS communication the use of the optionally available extension module
EM M09 is required. The extension module provides interface X2: MPI(PB) with fixed pin
Chapter 2.4 ‘Mounting’ on page 13
The PROFIBUS DP slave is to be con-
figured in the hardware configurator from Siemens. Here the configuration happens by
the sub module X1 (MPI/DP) of the Siemens CPU.
To switch the interface X2 MPI(PB) to PROFIBUS functionality you have
to activate the according bus functionality by means of a VSC storage
media from VIPA. By plugging the VSC storage card and then an overall
reset the according functionality is activated.

The configuration of the PROFIBUS DP slave should be done with the following
approach:
n
Activating bus functionality by means of a VSC
n
Hardware configuration - CPU
n
Use as DP slave
–
With activating the bus functionality
‘PROFIBUS DP slave’
by means of a VSC,
the bus functionality
‘PROFIBUS DP slave’
is unlocked.

Transfer of the entire project to the CPU
With the Siemens SIMATIC Manager, the CPU M13-CCF0000 from VIPA
is to be configured as
CPU 314C-2 PN/DP (314-6EH04-0AB0 V3.3)
The PROFIBUS DP slave is to be configured and connected via the sub
module X1 (MPI/DP).
8.2 PROFIBUS communication
n
PROFIBUS is an international standard applicable to an open and serial field bus for
building, manufacturing and process automation that can be used to create a low
(sensor-/actuator level) or medium (process level) performance network of program-
mable logic controllers.
n
PROFIBUS comprises an assortment of compatible versions. The following details
refer to PROFIBUS DP.
n
PROFIBUS DP is a special protocol intended mainly for automation tasks in a manu-
facturing environment. DP is very fast, offers Plug'n'Play facilities and provides a cost-
effective alternative to parallel cabling between PLC and remote I/O. PROFIBUS DP
was designed for high-speed data communication on the sensor-actuator level.
n
The data transfer referred to as "Data Exchange" is cyclical. During one bus cycle,
the master reads input values from the slaves and writes output information to the
slaves.
For the deployment in a super-ordinated master system you first have to project your
slave system as Siemens CPU in slave operation mode with configured in-/output areas.
Afterwards you configure your master system. Couple your slave system to your master
system by dragging the CPU 31x from the hardware catalog at
Configured stations
onto
the master system, choose your slave system and connect it.
