Hello,

I can give you maybe quick test solution, you can use utility mentioned in this topic:

https://support.industry.siemens.com/tf/ww/en/posts/communication-with-pc/161249/?page=0&pageSize=10

It's good application that can act as Server or Client with TCP or UDP protocol. With this application you can simulate your Server/Client in local network and test communication with S7-200.

New question published by watibe is split to a separate thread with the subject Communication between two old simatic step 7 PLC's S7-200 via cp 243-1 and cp 243-1 IT.
