Using PROFINET CBA communication and standard communication at the
same time
Note
The information in this section applies only if a singleton component was created from the
S7400 station. With a standard component, the connection information configured in STEP 7
is lost.
Parallel operation of PROFINET CBA communication and standard communication using the
services S7 communication and open 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.
For communication between a PROFINET CBA device and a conventional device, use S7 or
ISO transport, TCP or ISOonTCP connections.
Configure the S7 and TCP connections in STEP 7 as follows:
● 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
● for S5compatible communication (ISO transport / TCP / ISOonTCP connections)
– PROFINET CBA device: unspecified passive
– conventional device: unspecified active
This achieves the following:
● You can specify the connection partner for the conventional devices at any time with
STEP 7.
● 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).
