I wanna connect the PLC S7-226 from Siemens to the Kepware server. In the past I have been able to connect the Kepware OPC server to a S7-224 and S7300 family, but now I can't connect to the S7-226. I have read about the S7-200 OPC Server from Kepware and they mentioned that they can connect to all the S7-200 family but they don't list the CPU S7-226 specifically. This makes me think that they can`t connect to this CPU model.

I'm sure that I'm not making any mistakes in the communication configuration.

Do you know anything about this problem? Do you know any other free trial OPC server that you have used with the S7 200 CPU 226? I need it to be a free trial because is just for test purposes.

Please if you have any feedback let me know asap.
Thanks in advance for your help.

 

Hi,

There is an OPC server from SIEMENS that you can download it and use it as a trial program, find below the link:
