Oh god, I hope someone has had this issue before because it is doing my head in!
I am trying to add a 3rd Bus Coupler (TM3BCEIP) to an existing M262 (TM262L10MESE8T) installation.
I have installed these before and never had an issue.
The problem is, there are no errors at all (on Bus Coupler Web Interface & in PLC) and communication actually seems great!
But most of the IO will not update.
When I say most, literally the only thing that IS working is the Digital Outs.
The Digital In's, Analog Outs (not using any AI), and Temperatures are not coming through.
You can see there Inputs real values on the Bus Couplers Web Interface, but for some reason they are not making it through to the PLC!
The 2 existing Couplers continue to work just fine.
I have tried anything & everything I can think of, and I am also waiting on Schneider Support, but I need the solution last week!
Here is what I have tried (what I can remember anyhow):
- Upgrade PLC firmware (V5.1.7.23)
- 2 Different Bus Coupler's
- Ensure Bus Coupler latest FW (V2.1.50.2)
- DHCP & Fixed Address
- Tested & confirmed Ethernet lead is healthy
- Reduced IO RPI
- Reconfigured to only the DI & DO card and uncoupled the remaining cards
- Tried setting PLC Settings to Always Update IO (although I think the Bus Coupler's already have this setting over the top anyway).
It turns out to be an issue with the DI card, removing this resolves all issues, adding it to the end of the rack makes it the only one not working.
We tried replacing with another we had but same issue.
We have used these in the past so maybe something with new firmware?
Luckily we can get away without the inputs for the time being, waiting on Schneiders feedback now.
Thanks
