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.

Frequently asked questions

Do you repair Mitsubishi Electric plc repair & programming or only replace units?+
We repair at component level wherever it is economical — MELSEC FX5U / FX5UC (iQ-F), MELSEC FX3U / FX3G and MELSEC Q series and related models. Replacement is recommended only when the unit is genuinely beyond economic repair or spares are unobtainable, and we will tell you which rather than defaulting to a costly swap.
Which Mitsubishi Electric models do you cover for PLC repair and programming?+
We service MELSEC FX5U / FX5UC (iQ-F), MELSEC FX3U / FX3G, MELSEC Q series, MELSEC iQ-R and MELSEC-L / FX2N (legacy), including current and end-of-life generations. Tell us the exact model when you raise a request and we match a technician experienced on that Mitsubishi Electric platform.
Will my Mitsubishi Electric settings survive the repair?+
Yes. We back up parameters and programs with GX Works2 / GX Works3 before any hardware work and restore or verify them after repair, so your commissioning, Mitsubishi Electric application settings and referencing are preserved.
How quickly can you provide Mitsubishi Electric PLC repair and programming?+
We're a verified-technician network serving factories across India from our Hyderabad base. For registered factories we dispatch a technician in under 4 hours across Hyderabad's industrial clusters, and within hours through local technicians in other regions — including emergency Mitsubishi Electric breakdowns, 24/7. Where workshop repair is needed we collect, repair and reinstall with full load testing.
