Common PLC controller and automation module faults
We diagnose central controllers, local and distributed I/O modules and communication interfaces, covering both complete failures and intermittent faults.
- PLC controller does not start
- Controller stops or freezes during operation
- Unexpected restarts and unstable operation
- Fault appears only after warm-up
- Damaged digital or analogue inputs
- Damaged transistor, relay or analogue outputs
- Failures of local or distributed I/O modules
- Damaged communication modules and bus interfaces
- No communication with an HMI, industrial PC or other system modules
- Ethernet, Profinet, Profibus, CAN and other industrial network faults
- Damaged power supply section
- Failures after a surge, short circuit or overload
- Damage to memory, processor or mainboard
- Damage caused by moisture, corrosion, dust, vibration or long-term operation
