Dear List members,
I have to do a application to communicate with a PLC using Modbus Plus protocol.
I'm looking for a component or ActiveX or API to communicate to PLC in mode Master/Slave.
This PLC talk using modbus plus but it send responses in unnatended mode or unsolicted responses. Then the ActiveX that we know don't work, they only work in master mode.
Are there components that they works in slave mode, or applications that they are modbus plus slave simulators?
Thanks.
