hello friends,am new to this group, currently am working in automation company,so i have to communicate my python with my unitronics PLC v350 to fetch and write process variable, any one can give me a simple program or introduction
Does it have RS485 or Ethernet ports?
You could AdvancedHMI (google it) and use it to communicate with your PLC.
It supports VB.Net and C#.
For Python you need a Modbus library and I believe you can easily find one if look it up.
