Do HMIs fail?
Customer was trying to explain how he wanted a series of motors to start/stop. What he explained was what he should already have but when he pushed the Start for M1 on the display, M1 & M2 started. This happened several times during our discussion, then wham, only one started. Try again and two started. An operator confirmed later that you had a 50/50 chance of one or two starting depending on star alignment and mouth position. My first thought was an overlaping button display but placement of the fingertip did not seem to change anything.
We have moved several motors and of course now this is "our problem" even though we did not change any programing.
