Have a wierd one here.
Am running a plc5/80 E and attempted to install a new Analogue card for some new inputs, fairly straight forward. new 1771 IFE/C card.
Created new BT Data table, set up for differential wiring, set jumpers in card all ok, 21 words on BTW and 20 words on BTR, no problems. installed new card and set processor to run, all fine no errors.
when the plc is powered down and back up it faults with configuration error, reset the fault and all is ok, again when processor is switched off and on it faults every time. Its as if on power up the processor is not sending the configuration bits to the card.
I have tried setting up the card without the BT words just using normal integer words and exactly the same thing occurs.
I have got round it at the moment by installing an older type A Analogue card.
Has anyone ever come across this before, very intrigued and bemused, I am going to try it on a test rig but havnt got around to it yet.
Thanks in advance Jules
