06 / Overview
About Mitsubishi Electric PLC Repair & Programming
We repair and re-programme the whole MELSEC range — FX on compact machines, Q and iQ-R on larger plant, and legacy FX2N still in service. Typical calls are an ERR light with a diagnostic entry, a CC-Link/Ethernet segment fault, or lost retentive data after a battery (BATT LED) failure.
We upload and preserve the GX Works2/3 project before any hardware work — and for older FX where the GXW file is lost, recover the ladder from the running PLC, document it and return a commented, backed-up project.
