AUTOCON Product Lines We Repair
Our engineers are trained on the full AUTOCON product range. Below are the major product families we service.
AUTOCON ProLogix PLC Series
Compact and modular programmable logic controllers designed for discrete automation. Common failures include memory module corruption, real-time clock drift, and communication port faults in harsh industrial environments.
AUTOCON DataAcq Industrial Data Acquisition
Multi-channel analog and digital data acquisition modules for process monitoring and control. Typical repair issues include analog channel calibration drift, thermocouple input conditioning circuit failures, and 4-20mA transmitter interface breakdowns.
AUTOCON DistribuCom Industrial Communication Gateway
Fieldbus and Ethernet gateway controllers for integrating legacy and modern automation protocols. Common faults include Modbus TCP socket timeout errors, CAN bus termination failures, and Ethernet PHY layer instability under high EMI.
AUTOCON ProcessMon Real-Time Process Controller
Dedicated single and multi-loop process control modules for temperature, pressure, and flow regulation. Repair challenges include PID tuning parameter loss, sensor loop isolation relay faults, and output signal conditioning circuit failures.
AUTOCON SafeLogic Safety-Rated Controller
SIL2/SIL3-certified safety logic modules for emergency shutdown and fail-safe automation. Typical failures involve safety relay output verification faults, diagnostic circuit timeouts, and firmware signature validation errors after power anomalies.
AUTOCON HMI TouchPanel Series
Industrial touchscreen operator panels and text terminals for machine and process control interfaces. Common issues include LCD backlight degradation, resistive touch sensor calibration loss, and serial communication timeout with host PLC.

Common AUTOCON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AUTOCON equipment arriving at our workshop.
- ✓AUTOCON ProLogix Memory Checksum Error (ERR-17) — Firmware corruption occurs in ProLogix modules after voltage spikes or improper shutdown. The on-board flash memory develops bad sectors, preventing program verification and halting boot sequence. Particularly common in facilities with unreliable power supply or missing surge protection.
- ✓AUTOCON DataAcq Analog Channel Calibration Drift — Temperature fluctuations and age cause analog front-end reference voltage drift in DataAcq modules, resulting in 2-5% gain error on 4-20mA and 0-10V input channels. Affects sensor reading accuracy across entire data acquisition card.
- ✓AUTOCON DistribuCom Modbus TCP Socket Timeout (Fault Code 0xA2) — The DistribuCom gateway develops Ethernet PHY layer instability or TCP stack corruption under sustained industrial EMI, causing packet loss and gateway-to-PLC communication failure. Often triggered after maintenance work or equipment relocation.
- ✓AUTOCON ProcessMon PID Tuning Parameter Loss — Battery-backed SRAM on ProcessMon controllers fails after 8-10 years, causing complete loss of stored tuning coefficients (Kp, Ki, Kd) and setpoint history. Module reverts to default factory parameters and process control becomes unstable.
- ✓AUTOCON SafeLogic Relay Output Verification Fault (SIL2 Failure) — Safety-rated relay output verification circuits in SafeLogic modules develop contact erosion or coil insulation breakdown, failing the dual-channel monitoring self-test. This disables safety output and triggers demand shutdown. Common after high-cycle or high-current switching loads.
- ✓AUTOCON HMI TouchPanel Resistive Touch Calibration Loss — Resistive touchscreen sensors on AUTOCON HMI TouchPanel units degrade after 5-7 years of use or fail due to moisture ingress at display bezel seals. Touch response becomes non-linear and screen coordinates drift, rendering operator interface unreliable.

How do you handle AUTOCON firmware updates and calibration certificates?+
Every AUTOCON repair includes latest firmware version from manufacturer database and fresh calibration using NIST-traceable equipment. We provide ISO 17025 calibration certificates for analog modules, SIL certification re-validation documents for SafeLogic units, and firmware version logs for audit compliance. Digital copies are emailed; originals shipped with repaired unit.
Can you repair AUTOCON modules that show Checksum Error or Memory Corruption?+
Yes. AUTOCON memory corruption is our specialty. We extract corrupted firmware from EEPROM, perform binary analysis to recover customer program logic where possible, reload latest firmware image, and validate full boot sequence before dispatch. If customer program is unrecoverable, we provide blank module with factory firmware. Success rate is 94% across ProLogix, DataAcq, and DistribuCom series.
What is the warranty on AUTOCON repairs from Synchronics?+
All AUTOCON repairs carry 12-month comprehensive warranty covering parts and labor for same fault. We also offer optional 24-month extended warranty for high-criticality process control modules.
