Preserve the validated RSLogix 500 project, serial-port assignments, I/O map and expansion order before disconnecting the controller. Reconcile the two communications interfaces and the mixed relay/FET output wiring with the cabinet record. Commissioning must confirm program integrity, both serial paths, high-speed I/O and every embedded field point.
Important Notice: Verify the complete 1762-L24BXBR suffix and its additional programming/HMI port before treating another 24-point controller as a replacement.
