| Diagnostics & Protection |
Installation & Upgrades |
|
CONTROLLER DIAGNOSTICS
Review ROC system events, module status and communications before separating the expansion assembly.
|
POWER SEGMENT CHECK
Verify the documented 12 VDC supply, grounding and expansion-cable continuity under safe conditions.
|
|
SLOT ISOLATION
Remove or isolate one I/O module at a time to distinguish module faults from backplane faults.
|
EXPANSION ORDER
Record the controller and expansion sequence so slot addressing remains unchanged after service.
|
|
MODULE TRANSFER
Label each I/O module and transfer it to the matching slot only after confirming connector condition.
|
RETURN TO SERVICE
Restore configuration, verify every I/O point and confirm remote communications before release.
