Hi to everyone,

I am establishing the communication of s7200 on moodbus for that purpose my plc must acts as a slave. i have modsim and modscan software that works as a master. what i want to ask is that can anyone help me out to configure my siemens s7 200 cpu 226xm and can anyone send me the sample program. i'll be very thankful to you please help me out please...

 

Why don't use OPC for this? it's easier and quicker:

Here is a link to the OPC Server for Siemens S7 PLCs:
