Common Questions
California PLC Repair — FAQ
Answers to the most common questions from California plant engineers and maintenance teams about our PLC repair service.
How do I ship my PLC to Flexa Systems from California?
Request a free evaluation via our quote page, then ship to: Flexa Systems, 860 Hembry St Suite 401, Lewisville, TX 75057. From California, UPS/FedEx Ground typically deliver in 3–4 business days; overnight air is available for rush PLC repairs. Anti-static bag, then bubble wrap; include contact info and fault symptoms.
Will my PLC program survive the repair?
Yes. We back up the PLC program and I/O configuration before opening the unit, and fully restore it on return. For GMP-validated CA pharma environments, this is critical — preserving the program avoids costly re-validation. If the failure caused memory corruption, we will note it in the diagnostic report so you can plan re-download.
What California PLCs and brands do you repair?
Every major PLC brand deployed in California:
- Allen-Bradley ControlLogix, CompactLogix, SLC 500, MicroLogix, PLC-5
- Siemens SIMATIC S7-1500, S7-1200, S7-400, S7-300
- Mitsubishi MELSEC iQ-R, Q Series, FX5U, FX3U
- Omron Sysmac NX/NJ, CJ2M, CP1L
- GE Fanuc PACSystems RX3i/RX7i, Series 90-30/90-70
- Schneider Modicon M340/M580/Quantum, Beckhoff, B&R, Automation Direct, Eaton, Horner
How long does PLC repair take for California plants?
Standard turnaround is 5–20 business days from receipt of the unit — typically 5–10 days for current-generation CPUs (ControlLogix, S7-1500) and 10–20 days for discontinued legacy modules. Rush 24–72-hour service is available for CA production-critical failures.
How much does PLC repair cost?
PLC repairs save 40–70% vs. buying new. Typical ranges:
- Allen-Bradley CompactLogix / SLC I/O: $350–$900
- ControlLogix L7x / L8x CPU: $700–$2,000
- Siemens S7-1500 / S7-400 CPU: $800–$2,500
- Legacy Series 90 / PLC-5 / Quantum: $600–$1,800
Free diagnostic evaluation — you only pay if you approve the repair.
Do you repair discontinued PLCs still running in California plants?
Yes. Many California utilities, water treatment plants, and legacy manufacturing operations run Allen-Bradley SLC 500 / PLC-5, GE Series 90-30/70, and Modicon Quantum that have been discontinued by the OEM. Component-level repair is the only cost-effective option — replacement CPUs are unavailable or require full system migration. We maintain parts inventories for these legacy platforms.
