Unit is a Frame 9E, gas only, DLN-1 installed around 1997. It has a (factory installed) expansion card TBCB in <C> core and uses the <I> computer for communications (no HMI).
After I added a new input, TBCB card functioned normally for one to two days then stop updating inputs. No alarms, diagnostic or otherwise. I defaulted the card in the IO_Configurator and re-entered all the signals, generated a new IOCFG_C.DAT file and downloaded (and re-booted). Again, all worked well for a couple of days. Not sure if this is a new issue to this unit as the other inputs to this card tended to be very static and were for indication only.
I connected this new point into C_C_MAI26 and configuring it in the IO_Configurator as MA input on TCCB, Signal 12 (26 - 14 = 12 for the expansion card.) Signal worked well with correct configuration and was reading correctly up to the time it froze.
The only other change made to the <I> is that a Modbus connection was added, but I don't see how that could effect things. (?) There was no Modbus connection before.
Does anyone have experience with this card update problem? Suggestions are welcome.
Thanks in advance.
