Has anyone here used a software called Modbus Poll? I'm trying to prove to a customer that the Modbus slave function works, but I'm having a difficult time connecting using this software. Just curious if anyone has used it in the past and knows how to connect to an S7-200 with it. A free trial is available at modbustools.com.

I haven't had any problems connecting it to S7-200 system. Try this software and if you would have some problems you can contact me.
	Best regards, Darius
