CQM1H and Barcode

2 posts in this topic

24.07.03 Hi, Bob! Hi, Friends! The CQM1h CPU 61 no connecting via communication with others Plc’s. The Transistors Relays outputs of CQM1h CPU 61 starting others Plc’s CQM1h CPU 51. I ‘m using subroutine program for outputs. Baud rate peripheral port CPU 61: 9600 BPS Baud rate port RS 232C CPU 61:4800 BPS, becowce dip switches Barcode define for 4800 BPS, But no problem for chant to 9600 BPS. The CPU 61 reading Barcode correctly, but scan time is no constant. Interrupts program no use. Bob, send me your e-mail, please. I send my ladder diagram program. With best regards Alex.

Are your outputs turning on? If so, are the being read as inputs in the other PLCs? It may be a wiring problem. Check that out first by forcing a few bits to see if the inputs are turning on in the other PLCs.
