I am facing a "Registry Error" when I start RS Logix 500,
and also when I connect the PLC with my laptop the COM ports are not visible.
Need advise in solving this.....
Is it possible to bypass the Allen Bradley DH-485 link coupler using a CAT 5 communication cable.
My system Description:
SLC-500 <--> DH485 <--> DH485 <--> Panel View 550
