I am trying to get a digital output based on a barcode read. The scan talks to an IBM AS400 where it is verified as good or bad, if it is a bad scan the AS400 throws a 1 in an excel cell on a PC. I need to get an output to sound an alarm when that happens. I have a Direct Logic 05 PLC with Ethernet, and KEPDirect for PLC. When I get this to work they will be speread out all over the plant making an expensive application like Wonderware unreasonable. I have also tried Wago Field Bus but I dont write VB or C# so I can't make it work either. I would greatly appreciate any advice.
