I am trying to take a program that we wrote many years ago in IOControl that is now in PACcontrol and debug so that it can be sent to a GROOV Epic. Everything works except that I get the following error.
ERROR - Block #33 ‘Open Serial Communication’, line 2: Cannot locate instruction definition #511.
Block #33 includes the “Open outgoing communication” and there are two communication handles. I think the problem is the “initial value” in the communication handles, but I’ve not found a way to configure them to eliminate the error. Any clue why this error would occur and how to eliminate it.
