Hi All,
First time post and in dire need of some help. We have an ABB S3 palletizing boxes and all was good. We had a brown out yesterday on our electricity supply and since then the controller wont read its inputs or outputs. It will initialize and load the program, will move to the first pickup position and then shows 'waiting on input 1'.
If I read the inputs on the hand held it doesnt show any change in state for a box present at the pickup point. I interfaced with Sport and read its Digital IO and they dont show here either.
I replaced the IO card and as with the other card the input lights on the card but is not being read by the controller?? I reseated all ribbon cables and cards and still the same issue. If I manually (through handheld) try and toggle an output it wont do this either.
I replaced the CPU and the new one wont initialise. I swapped PROM's D25 & D26 over to the new CPU and it still wont initialise.
One other little question, the two PROMs D25 & D26, if replaced from new do these have to be flashed before use?
Any and all help would be much appreciated.
Thanks,
Michael.
