The Feller Engineering AF125 board is a PLC/add‑on module that interfaces via PROFIBUS and typically hosts an EPROM for firmware storage. Common failure points on this class of industrial control boards include degraded power supply traces, burnt I/O pins, or corrupted EPROM data leading to loss of communication with the host system. First‑check diagnostics: verify 24 V DC input and monitor for voltage drops during operation; inspect the board for burn marks or loose solder joints, especially around the PROFIBUS connector; and read any diagnostic LEDs or error codes from the host PLC to confirm whether the module is being detected.[oss-gpt-20b] |
