Common ControlLogix failures

Failure patterns we regularly see on ControlLogix hardware like the 1756-A5TSC:

CPU major faults after power loss or corrupted projects
1756 Ethernet modules (EN2T / EN3T) dropping connections under load
Power supply failures causing chassis-wide resets or a dead rack
I/O module channel damage from field wiring faults
Battery or energy storage module failures losing programs on older L6x CPUs

Repair or replace?

ReplaceReplace the 1756-A5TSC if it will not boot, shows a solid red fault light, or has lost its program. Another ControlLogix Chassis takes the same program: download it, match the firmware, and the line is running again. We source the 1756-A5TSC on request, so weigh that lead time against a repair turnaround.

RepairRepair the 1756-A5TSC when the fault is in the power section, a port or the status display rather than the processor core, or when the controller carries a firmware revision or validated project you cannot easily re-flash onto a different unit. If a replacement is already installed, repairing the failed 1756-A5TSC gives you a tested spare on the shelf for the next failure. Every 1756-A5TSC repair is fully function-tested and covered by a 1-year warranty.
