Adamkse Posted January 9, 2020 Report Share Posted January 9, 2020 Hi, I have recently installed a URB-TCP expansion module into an existing system. My issue is that the MOD light is FLASHING RED and my IOS light is FULL RED. Connected, I have a DO08CH URD-0008CH in slot 1 and a AI08O URA-0800O 8 Analog Current Inputs, 10 RTB in slot 2. The AI08O has all 8 LEDs flashing green. I can ping the module so I think it is communicating OK. Any help or info would be great. Let me know if you need any more information. Cheers, Adam Quote Link to comment Share on other sites More sharing options...
