Operational Considerations

During program execution, the 1772-LG monitors input devices and controls output devices based on user-defined instructions. It’s important to note that when local I/O racks are powered by specific power supplies (such as 1771-P3, 1771-P4, 1771-P5, or 1771-P7), the module may encounter issues with the racks. In such cases, power cycling the processor or adjusting the keyswitch to the program load position before returning to RUN mode can resolve potential faults.
