Hello Siemens,

Hello Anil. I suggest that you contact a representative of Siemens close to you. This international forum does not know the S7-200 Smart range well. (Or more accurately said.. members knowledgeable of the Smart range do not volunteer answers often.)

I am expecting the coding structure to look similar to what we use on the S7-1200 and S7-1500.

The situation changes slightly if you have coded something already and needs help to decode some of the status messages you get. It that case you can share some screen captures in a ZIP file.

Closed cause question posted twice.

The second thread with the subject tcp/ip is published within the conference SIMATIC S7-200.
