hostlink and modbus at the same time.

Posted 11 Oct 2021

Hi in previous times i made a plc program with hostlink to connect two cp1L-20 plcs together which has been working well for years, problem i now have is is that the system was previously using I/O to control a danfoss VSD.

I have made a program to talk to the danfoss drive using modbus using rs232 (no protocol) but talking to the other PLC with modbus is proving troublesome to fit the code in the plc.

Is there some way I can use hostlink and modbus at the same time ? so the slave plc and the drive will havg off the same cif12
