I need to communicate to the SSR M22-150KW Intellisys Controller with a modbus RTU (RS-485 2 wires). The operator panel is SSR M22-150KW. There is a Intellisys Remote Interface to communicate with SSR M22-150KW controller. I have read carefully the instruction manual of the Intellisys Remote Interface. ADDRESS [Ad], BAUD RATE [bl] and COMMUNICATIONS MODE [CO] exactly the same on the Intellisys Remote Interface and Siemens PLC. Do other settings on the controller needs to be done? Programming is done according register listing with Function Code 03. The IRI's Network port is an RS-485 interface that used in a half-duplex mode. Is this enough? If the network is connected to the Intellisys Remote Interface, Network Port LED is flicker?
