Hello
OK what i have is a prince diecast machine with 4 encoders on the tie bars to measure the tie bar strech that give me the tonage of the tiebar the plc is control logix5000 with 2 1756 high speed counter cards reading the encoder counts
The problem im having is the counts are not the same all the
time and on the ladder program the raw count is changeing even though the indictor lights on card is not in turn my tonage is all over the place
I have changed power supply checked all conections 2 new
cards still same results and tried differt encodes and played with roll over counts still same problem any clues
