The DIDDE 373‑565 (B65.1) board is an industrial programmable logic controller used in machine control and process automation. Common failure points on this model include power supply decoupling failures, overheating of the main CPU or I/O modules, and degradation of surface‑mount components such as electrolytic capacitors or MOSFETs. Begin troubleshooting by verifying the input voltage and ripple at the board’s power rails, inspecting for burnt or swollen components, and checking all I/O connections for continuity and proper grounding. If a diagnostic LED or error code is present, cross‑reference it with DIDDE’s service manual to isolate the fault.[oss-gpt-20b] |
