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

 

Has your SLC500 series PLC a DH-485 connection?
Has your Panelview 550 a DH-485 connection?
If yes to both - where would you wire the screens ?
and the spare cores ?

What’s the length of cable and would it be in an industrial environment ?
Screened 2 core (twisted pair) or preferably armoured with drain wire is appropriate here, and cheaper than CAT 5.
It’s unclear what the link coupler would achieve apart from isolation.

 

Hamza,
Yes,The SLC-500 rack does support an ethernet module.
Yes, some Panel View 550 had ethernet support.
The question is why you want to abandon RS485 for ethernet.

The problem I am facing is that using the standard configuration the PV550 is showing error "No active nodes found on network", now I have by passed the link coupler and connected the PV550 directly using the 1747-C10 cable from the PLC. In doing this I had to change the PV550 position from its original.
Now I want to place the PV550 to its original position and use the CAT-5 cable with RJ-45 connectors, normalize the system.
