Control system faults can stop production, trigger repeated alarms, or cause equipment to behave unpredictably. EMAN FTC provides Control System Fault Analysis Services in Saudi Arabia for PLC systems , HMIs, SCADA systems, VFDs, sensors, control panels, and industrial communication networks.
Our goal is simple: find the real cause of the fault, not just reset the alarm.
For example, a VFD trip may not be caused by the drive itself. The real issue could be a faulty sensor, incorrect PLC command, loose wiring, or unstable control voltage.
What We Diagnose
We can investigate faults involving:
- PLC inputs, outputs, logic, and communication
- HMI and SCADA communication problems
- VFD and soft starter faults
- Sensors and instrumentation
- Control panels and wiring
- Industrial communication networks
- Interlocks and sequence problems
- Intermittent and recurring faults
A machine may stop and show a motor alarm, but the real cause could be a proximity sensor that occasionally loses its signal. Our fault analysis follows the complete control chain to find where the problem starts.
PLC and Automation Fault Troubleshooting
PLC faults are often connected to field devices, wiring, communication, or process conditions. Our PLC Troubleshooting & Maintenance Services help identify problems involving PLC logic, inputs, outputs, communication, and connected field equipment.
We check the PLC together with the connected equipment to determine whether the problem is coming from the controller, I/O, field device, or control logic.
For example, if a pump does not start, the motor may be healthy and the PLC output may be correct. The actual cause could be a low-level interlock preventing the start command.
HMI, SCADA and Communication Faults
If the HMI shows incorrect values or SCADA loses communication, we trace the signal from the field device to the PLC and then to the operator screen.
For HMI-specific problems, our HMI Troubleshooting & Configuration Services cover communication faults, incorrect values, configuration problems, and PLC-to-HMI connectivity.
For larger monitoring and control systems, we also provide SCADA System Integration & Support Services for communication, data monitoring, system integration, and troubleshooting.
Common issues include:
- Incorrect data
- Missing signals
- Communication loss
- Device offline alarms
- Incorrect tags
- Unstable network connections
This helps identify whether the problem is in the field device, PLC, network, or HMI/SCADA configuration.
VFD and Motor Control Fault Analysis
Repeated VFD trips do not always mean the VFD needs replacement. Our VFD Installation & Services support industrial motor-control applications where drive configuration, commands, feedback, or operating conditions need to be checked.
We can check:
- Fault codes
- Drive parameters
- PLC commands
- Speed reference
- Motor conditions
- Control wiring
- Feedback signals
For example, an overload trip may be caused by incorrect motor parameters or excessive mechanical load rather than a failed VFD.
Soft Starter Fault Analysis
Motor starting problems can also originate from incorrect settings, control signals, electrical wiring, overload conditions, or communication issues.
EMAN FTC provides Soft Starter Installation & Configuration Services in Saudi Arabia for industrial motor applications requiring correct setup, configuration, testing, and troubleshooting.
Our Fault Analysis Process
1. Review the fault
We check alarm codes, screenshots, equipment details, and when the problem occurs.
2. Inspect the control system
We review PLCs, HMIs, drives, sensors, control panels, and connected devices.
3. Trace signals and communication
We follow the signal path to find where information or commands are lost.
4. Identify the root cause
We determine whether the issue is related to wiring, logic, configuration, hardware, or communication.
5. Recommend corrective action
This may include repair, parameter adjustment, PLC modification, component replacement, or system upgrade.
