I am having trouble communicating between an existing plc5/20 and a newly installed, in slot 16, basic module. The basic program was copied out of another basic that does the same thing on another machine. It is comm. with a plc5/30 though. Is there anything in the basic programm that tells what plc it is communicating with? Any ideas would be appreciated...
Thanks,
