Demo Modbus or Ethernet Softwares

Hii.. I am trying to build node red gateway that will talk to plcs to get the data using modbus/Ethernet. So, Can anyone suggest me any demo plc software so that I can connect node red to that plc?

Hello Omkar,

For Modbus slave simulation i use pyModSlave

Can we create tags in that 'pyModSlave' software? I just want to the data which is frequently changing?

Tags ? no its just for Modbus .. sorry im not familiar with modbus having tags.

maybe you add them later once you read the registers you need with node-red-contrib-modbus
