I'm currently using a PLC to get results from a tester, and mark the part if its bad like 34 parts down the line. This is working great, but I would like to use my HMI so anyone can change which part is getting marked. Basically the good or bad signal is coming in 60 mS after a trigger signal on 3 lanes and I'm doing a bit shift right. Then im saying if like 34 bits into my 64 bit array is low during during this trigger interval, signal the videojet. So, for my HMI to change it, the "examine if open" would have to be modified, and I don't think the HMI can do this. The PLC is a micrologix 1200, and the HMI is an ST401. Let me know if something sounds stupid or doesnt make sense. Have no fear of insulting me.
