The analog input card 3700A of triconex PLC fails often. In the diagnostics it shows "voter fault" along with the point(s) where it occurred.
It has to be noted that this happens only in one channel. The PLC has totally 5 AI channels. Each time when the voter fault occurs it shows different point every time. Some time it shows "1-32" indicating that all the points are at fault. How do I correct this problem? I have already replaced 10 cards on this particular channel.
