6.4 Using PROFINET CBA communication and standard

communication at the same time

Notice

The information in this section applies only if a singleton component was created

from the S7-300 station. With a standard component, the connection information

configured in STEP 7 is lost.

Overview

Parallel operation of PROFINET CBA communication and standard communication

using the services S7 communication and S5-compatible communication 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 ISP transport, 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 CBA devices in SIMATIC iMap (in other words
