SMW System 60 is a programmable industrial controller typically used for motion‑control and indexing applications in machining or packaging equipment. Common failure points on this class of controllers include degraded power supply modules, burned‑out I/O relays, and corrupted firmware stored in the internal flash memory. Begin troubleshooting by verifying that the 24 V DC input rail is stable and within spec, checking all external signal lines for continuity and proper logic levels, and reviewing any diagnostic LEDs or error codes displayed on the front panel. If power and I/O are nominal, perform a quick firmware checksum against the latest revision to rule out software corruption.[oss-gpt-20b]
