Summary:
You can no longer purchase the modules CP343-1 TCP or CP341-1 ISO, CP443-1 TCP or CP443-1 ISO separately.  What are the alternatives? 

Solution:
Siemens Ltd has released new modules for the S7-300 and S7-400 family of PLCs.  The new modules are now designated CP343-1 and CP443-1 Industrial Ethernet respectively.  The new modules have a combined port which support TCP/IP and ISO Layer 4.

Citect S7 drivers will work with the new Siemens Industrial Ethernet modules.  However, the setup for the communication between Citect and the Siemens S7 PLC requires some additional configuration on the S7 PLC side.
