Hello All, 

 

I am college graduate student and I know little bit of cx-programmer for modifying existing program. I have master CJ2M CPU34 PLC connected with three CP1L PLC. All 4 PLC are connected via hub through Ethernet cable. I want to read/write some memory data to/from PLC through Python programming. As I am new to PLC and Python I have not much idea regarding omron PLC and python communication. So is it possible to connect python with master/slave PLCs directly? If yes then how can I communicate? I was trying with cpppo library to connect with PLC but I could not connect it. 

I have attached the master PLC communication setup for the reference. 

 

Any kind of lead/help is appreciated. 

 

Thank you in advance.
