Allan Case,
I was incorrect about the PV1200, it is on RIO.
bellies,
That is probably what happened.
This PLC application was imported over to RSLogix from AI series. I looked back at the old AI series files (still have them saved) and I see that they also have that line. The PLC5 must be made to accept it some how from the import utility.
jstolaruk,
I will try going without the line and see what happens.
Thanks everyone,
Bill
