I am doing a project in which i have to communicate to the CIM of Honeywell's 620-0043 PLC. It uses the modicon modbus RTU protocol. I need to know the procedure for the RS232C's connection between a PC and the CIM. Can anyone help?
I would check that it is actually the Modbus protocol -- I believe that the HW 620 plc protocol was similar to Modbus but with some subtle variations that required a new driver to be written.
Hello, Myself and some friends of me worked for many years here in Germany in the Honeywell IPC 620 Service and Application Department. Now we are busy as free lancing engineers and supporting IPC 620 Installations. If need more information about 620-0043 or the 620 system in general let me know, a friend me must have a manual for this Modbus module.
