S7TCP driver communication fails with S7-200 with CP243 in zenon 12

S7TCP driver communication fails with S7-200 with CP243 in zenon 12

Description

With S7-200, communication via S7TCP with CP243 in zenon 12 fails. However, communication worked in previous versions.

This is due to changes in the COTP package. The difference lies in the source reference.

This error has been fixed. The TCP/IP - RFC1006 protocol can now process different source references. Communication works as expected again.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 12 or higher.
