7.4 Using PROFINET CBA Communication and Standard
Communication at the same Time
Overview
Parallel operation of PROFINET CBA communication and standard communication
with the S7 communication and S5−compatible communication services is possible
with the CP.
This mode is important for your application when, for example, you want to
implement communication between existing ”conventional” SIMATIC devices and
PROFINET CBA devices in an existing system.
The special feature is that the configuration of the communication for PROFINET
CBA devices is only possible in SIMATIC iMap. Communication with conventional
devices, on the other hand, requires that the connections are configured in
STEP 7.
Recommended Procedure
Here, we would like to give you a few tips and recommendations.
For communication between a PROFINET CBA device and a conventional device,
use S7 or TCP or ISO−on−TCP connections.
Configure the S7 and TCP connections in STEP 7 as follows:
S for S7 communication
− PROFINET CBA device:
single−ended, passive (partner unspecified)
(no configuration is necessary if the device involved in S7 communication is
operated simply as a server).
− conventional device: single−ended, active
S for S5−compatible communication (TCP / ISO−on−TCP connections)
− PROFINET CBA device and specified, passive
− conventional device: unspecified, active
This achieves the following:
S You can specify the connection after for the conventional devices at any time
with STEP 7.
S You can use the PROFINET devices in SIMATIC iMap (in other words connect
them) without having to change the connection configuration again in STEP 7;
the devices are always ready to send and receive on the configured
connections (connection is established by the active partner).
For the PROFINET CBA device, this means the following procedure:
