HMS Product Lines We Repair
Our engineers are trained on the full HMS product range. Below are the major product families we service.
iGateway
HMS iGateway devices provide protocol conversion and edge intelligence for legacy and modern industrial networks. Common repairs include Ethernet port failures, power supply faults, firmware corruption preventing device boot, and communication protocol stack errors causing data loss or latency issues.
Wireless Access Points and Industrial IoT Adapters
HMS wireless connectivity modules enable factory floor communication and remote monitoring. Typical faults include RF module failure, Wi-Fi / cellular antenna misalignment, MQTT broker connection loss, and SSL certificate expiration causing secure tunnel shutdown.
Protocol Converters and EtherCAT Masters
HMS protocol bridge controllers translate between Modbus, PROFINET, EtherCAT, and other industrial standards. Repair focus includes failed communication sessions, incorrect node addressing, master / slave synchronization errors, and cyclic data timeout faults.
Industrial Ethernet Switches and Redundancy Controllers
Managed Ethernet switches for plant network backbone with RSTP, MRP, and HSR ring redundancy. Common issues include port LED malfunction, spanning tree protocol loop formation, managed VLAN configuration loss, and backup power battery drain.
HMS Anybus CompactCom Family
Multi-protocol communication modules for PLCs, drives, and I/O terminals. Typical faults involve gateway communication stalling, dual-interface failover not triggering, firmware rollback failure, and CRC checksum errors in real-time data packets.
HMS MobiLED and Remote Monitoring Modules
Cloud-enabled telemetry and remote equipment monitoring solutions for distributed factories. Repair challenges include API authentication timeout, cellular module pin configuration loss, sensor data aggregation lag, and database connection pooling exhaustion.
Why Choose Synchronics for HMS Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on HMS equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common HMS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HMS equipment arriving at our workshop.
- ✓Ethernet port no link / communication timeout — HMS gateway Ethernet RJ45 connector pin oxidation, magnetics transformer failure, or PHY chip malfunction. Port LED remains dark despite cable insertion and active network traffic.
- ✓Gateway device fails to boot or enters recovery mode — HMS iGateway firmware corruption due to power loss during update, failed bootloader sector, or DDR memory ECC errors. Device stuck in bootloader waiting for firmware image upload.
- ✓Protocol communication stack errors or missing gateway route — HMS protocol converter lookup tables corrupted, incorrect source / destination IP addressing in gateway rules, or ARP table poisoning preventing host discovery in PROFINET or EtherCAT networks.
- ✓Wireless adapter disconnects or signal strength drops rapidly — HMS wireless module RF connector loose or corroded, antenna cable shielding damaged, Wi-Fi transceiver thermal throttling, or 2.4 GHz / 5 GHz channel interference from adjacent access points.
- ✓MQTT broker connection refused or SSL certificate expiration — HMS IoT gateway holds expired TLS certificate or cannot reach certificate authority server for renewal. Broker authentication failure prevents cloud data upload and remote monitoring access.
- ✓Ring redundancy (MRP/HSR) failover not triggering on primary port failure — HMS redundancy controller not detecting primary link loss, secondary ring port disabled, or ring manager protocol timer misconfiguration causing delayed switchover beyond plant tolerance.

Frequently Asked Questions — HMS Repairs
Do you repair HMS equipment anywhere in India?+
Yes. Synchronics repairs the full HMS product range including iGateway devices, protocol converters, wireless adapters, Ethernet switches, and IoT modules. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all metro and tier-2 cities. All repairs completed at our certified facility in Vadodara, Gujarat with 2-5 day turnaround.
What HMS equipment do you repair most frequently in Indian plants?+
HMS iGateway devices and protocol converters are most common in Indian automotive and pharmaceutical lines seeking legacy / modern network bridging. Wireless IoT adapters are increasingly repaired for distributed factory monitoring. Ring redundancy controllers (MRP/HSR) are critical for uninterrupted production environments. We maintain spare HMS modules for emergency swap-out to minimize downtime.
Can you diagnose HMS communication faults without physical repair?+
Absolutely. Synchronics offers HMS network diagnostic analysis — we capture gateway logs, analyze protocol traces, and identify root causes via remote session or on-site inspection. Common diagnostics include Modbus register mapping errors, PROFINET DCP broadcast storms, and EtherCAT cycle time overruns. We provide written diagnostic report with repair quotation.
Do you have spare HMS parts in stock for emergency repairs?+
Yes. We maintain inventory of common HMS modules — iGateway modules, Ethernet port cards, wireless transceiver boards, and power supply units. For critical automotive or pharma plants, we offer loaner equipment during repair. Original HMS spare part availability confirmed before accepting each repair job.
How do you handle HMS firmware updates and protocol configuration during repair?+
Post-repair, we reflash factory firmware or customer-specified HMS firmware versions using official HMS update tools. We restore gateway configuration files from customer backups or reconfigure from scratch using your network documentation. Full protocol handshake and data flow testing performed before dispatch to confirm production readiness.
How do I send my HMS 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 HMS 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 HMS 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 HMS 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.
