Guides for PLC I/O Modules
- Legacy PLCsSLC 500 End of Life: Keep Running or Migrate?Where the SLC 500 stands, which spares keep one running, and how a phased move to CompactLogix keeps downtime short.
- Parts identificationHow to Read an Allen-Bradley Catalog Number & SeriesBulletin numbers, module codes, suffixes, the series letter and firmware revision, and how each one affects whether a replacement will work.
Troubleshooting guides
- TroubleshootingPLC I/O Module Fault or Not Responding: First ChecksModule status LEDs on ControlLogix, SLC 500, S7-300 and S7-1500 I/O, the Logix connection codes (16#0204, keying 16#0114/0116), power, slot, keying and field wiring checks.
- TroubleshootingPLC Won't Go to RUN? Allen-Bradley Mode and Fault ChecksKeyswitch and mode-switch positions, the faults that block RUN, firmware and project mismatches, missing or wrong I/O modules, forces, and the order to check them in.
- TroubleshootingControlLogix & CompactLogix Major Fault Codes ExplainedMajor fault types and codes (T01 power-up to T07 memory), where to read them in Studio 5000, minor vs major vs I/O faults, the first checks and clearing a fault safely.
- TroubleshootingSiemens S7-300/S7-400 SF & BF LEDs and Diagnostic BufferSF vs BF (and INTF, EXTF, BUSxF on the S7-400), steady vs flashing, reading the diagnostic buffer in STEP 7, and the first checks for modules, PROFIBUS, PROFINET and backup batteries.
