HORNER Product Lines We Repair
Our engineers are trained on the full HORNER product range. Below are the major product families we service.
Horner cPDU Series
Compact programmable display units combining PLC and HMI functionality in one device. Common issues include touchscreen malfunction, memory faults, communication loss via Ethernet or serial ports, and logic solver crashes after power surges.
Horner XL Series
Modular automation controller platform offering distributed I/O, multi-protocol communication, and high-speed process control. Typical faults include analog input/output card failures, Modbus RTU communication errors, 24VDC power supply issues, and firmware corruption.
Horner OCS Series
Open control systems for machine automation, packaging lines, and material handling. Common repair needs include digital input/output relay failures, stepper motor drive faults, emergency stop circuit malfunction, and sensor interface card degradation.
Horner ePAC Series
Edge programmable automation controller combining PLC logic, HMI, and data logging. Repairs often involve SD card read/write errors, Ethernet module faults, real-time clock battery replacement, and graphical display rendering issues.
Horner Communication Modules
Gateway and interface cards for PROFIBUS DP, Modbus TCP, CANopen, and Ethernet connectivity. Issues include protocol handshake failures, port damage from surge, DIN rail contact corrosion, and firmware version incompatibility.
Horner I/O Expansion Modules
16/32-channel analog and digital input-output cards for extended process control. Common faults involve isolated channel dead zones, opto-coupler burnout, voltage reference errors, and DIN connector pin corrosion from humidity.

Common HORNER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HORNER equipment arriving at our workshop.
- ✓Horner HMI touchscreen unresponsive or flickering — Digitizer IC failure, loose ribbon cable connection, or LCD backlight inverter malfunction in cPDU and ePAC display units. Humidity and thermal cycling in Indian plant environments accelerate this.
- ✓Horner PLC communication loss (Modbus, PROFIBUS, Ethernet) — Communication module firmware corruption, damaged RJ-45 port, missing termination resistor on serial lines, or electrical noise interference from nearby VFDs and servo drives in factory environments.
- ✓Horner I/O card channel failure (analog input shorted or open) — Opto-coupler IC burnout from excessive input surge, faulty protective circuitry, or sensor supply voltage overshoot. Plant-side field wiring contamination and moisture ingress degrade isolation resistors over time.
- ✓Horner PLC memory or logic solver crash with watchdog timeout — Corrupt program flash memory from interrupted programming cycle, low backup battery voltage, or software logic loop exceeding scan time limits. Power quality issues and surge events trigger this in industrial settings.
- ✓Horner cPDU or ePAC Ethernet port intermittent or no link — RJ-45 connector pin oxidation, damaged PCB trace on Ethernet interface, or network isolation transformer failure. High-temperature plant floors and humidity promote connector corrosion in Horner devices.
- ✓Horner XL/OCS series 24VDC power supply browning out or shutting down — Capacitor aging and electrolytic degradation, shorted rectifier diode, or excessive load current from expanded I/O modules. Dust accumulation and poor ventilation in panel-mounted units reduce heat dissipation.

Frequently Asked Questions — HORNER Repairs
Do you repair Horner equipment anywhere in India?+
Yes. Synchronics repairs the complete Horner product range - PLCs, cPDU/ePAC controllers, HMI touchscreens, I/O modules, and communication gateways. We offer PAN India doorstep pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all major cities. All repairs are performed in our factory in Vadodara, Gujarat with a typical 3-5 day turnaround.
What is the warranty on Horner controller repairs at Synchronics?+
All Horner repairs carry a 6-month parts and labor warranty covering component defects and workmanship. If the same fault recurs within warranty, we repair it free of charge. We also offer extended 12-month warranties on high-value ePAC and XL series units for manufacturing facilities with critical uptime needs.
Can Synchronics repair Horner HMI touchscreen display issues without full controller replacement?+
Yes. We specialize in isolating display-only faults in Horner cPDU and ePAC units. If the issue is limited to the digitizer IC, backlight inverter, or LCD panel, we replace just that component while preserving your program logic and configuration. This saves 40-50% versus full unit replacement. We perform this work for food processing lines, textile mills, and automotive suppliers across India.
What Horner communication protocols does Synchronics support in repairs?+
Synchronics repairs all Horner communication modules including Modbus RTU/TCP, PROFIBUS DP, CANopen, Ethernet, and legacy serial interfaces. We have protocol analyzers and diagnostic software to test each interface under load. If your plant uses mixed Horner and third-party devices (Siemens, ABB, Allen Bradley), we ensure full interoperability post-repair.
Does Synchronics have spare parts for Horner devices in stock?+
Yes. We maintain inventory of critical Horner components including digitizer modules, communication cards, opto-coupler ICs, electrolytic capacitors, and backup batteries. For specialized modules like HE695 PROFIBUS or HE696 CANopen, we source from authorized distributors with 2-3 day lead time. This minimizes downtime for urgent repairs at sugar plants, pharma units, and packaging lines.
How do I send my HORNER 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 HORNER 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 HORNER 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 HORNER 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.
