COTS Product Lines We Repair
Our engineers are trained on the full COTS product range. Below are the major product families we service.
COTS Industrial Motion Controllers
Multi-axis motion control platforms used in textile machinery, packaging lines, and CNC retrofit applications. Common failures include servo feedback signal loss, encoder communication faults, and PWM output stage degradation requiring precision servo-loop recalibration.
COTS Distributed I/O Modules
Modular input/output systems for remote sensor and actuator connectivity in factories across India. Typical issues include isolated channel failures, power supply degradation in harsh environments, and Modbus/Ethernet communication timeouts requiring node-level diagnostics.
COTS Programmable Logic Controllers
Compact, standardized PLCs for discrete manufacturing and process control in Indian textile, pharma, and automotive plants. Repair challenges include memory corruption, real-time clock battery failure, Ethernet port short-circuits, and ladder logic compilation errors requiring firmware restoration.
COTS Human-Machine Interface (HMI) Panels
Touchscreen and button-based operator stations for machine and production line control. Frequent failures include LCD backlight degradation, capacitive touch controller faults, serial communication breakdowns, and embedded Linux filesystem corruption requiring display reconditioning.
COTS Power Supply and Redundancy Modules
Industrial-grade DC and AC power conditioning units designed for mission-critical automation. Common faults include input rectifier bridge failure, output regulator thermal runaway, battery backup circuit degradation, and redundancy arbiter logic failures requiring precision power electronics repair.

Common COTS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COTS equipment arriving at our workshop.
- ✓COTS PLC memory corruption and boot failure — Unstable power conditions, firmware update interruption, or EEPROM cell degradation in Indian industrial environments with frequent voltage fluctuations. Manufacturing facilities without proper UPS protection experience accelerated failure rates.
- ✓COTS motion controller servo loop instability — Encoder signal noise from high-EMI textile and packaging machinery, feedback cable degradation, or PID tuning drift after thermal cycling. Indian plants with poor grounding infrastructure see elevated servo noise coupling.
- ✓COTS distributed I/O node Modbus timeout and communication loss — Isolated channel power supply collapse, Ethernet PHY chip damage from surge events, or protocol stack timeout due to firmware bugs under high message frequency in networked Indian manufacturing lines.
- ✓COTS HMI touchscreen LCD backlight failure and display dimming — Electrolytic capacitor aging in power inverter circuit, LED driver IC burnout from thermal stress, or long operating hours (5000+ hours) in Indian plant environments without climate control. Humidity acceleration affects display lifespan.
- ✓COTS power supply redundancy arbiter logic failure — Watchdog timer circuit malfunction, redundancy decision logic corruption in FPGA or microcontroller, or cross-coupling latch failures preventing clean power switchover. Critical in Indian pharma and food processing where uptime is non-negotiable.
- ✓COTS embedded Linux filesystem corruption on industrial HMI and controller — Unclean shutdown during power loss, SD card or flash storage wear-out after 3000+ write cycles, or kernel panic from device driver bugs. Indian plants with frequent power interruptions face high corruption rates.

Frequently Asked Questions — COTS Repairs
Do you repair COTS equipment anywhere in India?+
Yes. Synchronics repairs the complete COTS industrial electronics portfolio — motion controllers, distributed I/O modules, PLCs, HMI panels, and power supplies. We offer PAN-India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other major industrial cities. All repairs are processed in our Vadodara, Gujarat facility with 24-48 hour turnaround.
What is your repair success rate for COTS PLC and HMI controller failures?+
Synchronics achieves 94% first-pass repair success on COTS PLC and HMI platforms. Our engineers perform root-cause analysis on every unit, replacing only damaged components and never using band-aid fixes. We provide detailed failure reports and preventive maintenance recommendations to help Indian manufacturers avoid repeat failures.
Can you restore COTS motion controller servo loops after catastrophic encoder failures?+
Absolutely. Our servo and motion control specialists rebuild COTS motion controller servo paths from component level, including encoder interface restoration, signal conditioning repairs, and complete PID re-tuning. We test restored controllers against your actual machine load profiles and provide final validation with dynamic step-response analysis.
Do you offer firmware recovery for COTS PLC and HMI after memory corruption?+
Yes, Synchronics specializes in COTS embedded firmware recovery. We extract original firmware from backup sources, restore bootloader configurations, rebuild Linux filesystems on HMI units, and reflash EEPROM code in PLCs. We verify memory integrity using sector-level diagnostics and deliver units with full functional testing.
How do you handle COTS redundancy power supply arbiter logic failures in critical applications?+
Synchronics performs hardware-in-the-loop testing on COTS redundancy modules, diagnosing watchdog timer circuits and crossover logic. We replace failed control ICs, restore FPGA configurations, and validate switchover timing under simulated power loss. We provide redundancy certification with test documentation for audit compliance.
How do I send my COTS unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a COTS drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on COTS repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your COTS unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
