Human Machine Interfaces are an important part of industrial automation systems, allowing operators to monitor equipment, view process values, control machines, respond to alarms, and interact with PLC-based systems. EMAN FTC provides HMI troubleshooting and configuration services for industrial and commercial facilities across Saudi Arabia, including Riyadh. Our services cover HMI diagnostics, programming, screen configuration, communication troubleshooting, PLC integration, alarm configuration, tag setup, testing, and commissioning.

HMI Troubleshooting Services
When an HMI stops working correctly, the problem may not always be with the operator panel itself. HMI faults can be caused by communication settings, PLC configuration, incorrect tags, network problems, wiring, power supply issues, software configuration, or faults elsewhere in the automation system.
We check the HMI, connected PLC, communication network, control signals, configuration, tags, and system settings to identify the cause before recommending corrective action.
✓ HMI not communicating with PLC ✓ Communication timeout faults ✓ Incorrect values on HMI screen ✓ HMI screen freezing ✓ Missing or incorrect tags ✓ Alarm display problems ✓ Touchscreen response issues ✓ Network communication faults ✓ PLC-HMI data mismatch ✓ Incorrect communication parameters ✓ Lost or incorrect configuration ✓ Unexpected HMI shutdowns
HMI Configuration & Programming Services
An HMI must be configured according to the machine, process, PLC program, and operating requirements. We configure operator interfaces so that equipment status, process information, controls, alarms, and operating values are presented clearly to the user.
HMI configuration can include screen development, navigation, push buttons, indicators, numerical displays, setpoints, tags, alarms, trends, user access, and communication settings.
✓ HMI screen configuration ✓ HMI programming ✓ Operator screen development ✓ Tag configuration ✓ Control button setup ✓ Alarm configuration ✓ Trend display configuration ✓ User access setup
PLC & HMI Communication Troubleshooting
Communication between the HMI and PLC is essential for displaying process values, equipment status, alarms, and operator commands. If communication fails, the HMI may stop updating, show incorrect values, display communication errors, or prevent operators from controlling equipment.
We can check communication protocols, IP addresses, device settings, PLC tags, HMI tags, network configuration, cables, switches, communication modules, and relevant software settings.
Our PLC Troubleshooting & Maintenance Services can also support faults involving PLC programming, communication modules, I/O, or the wider control system.
HMI Screen & Operator Interface Configuration
A well-organized HMI helps operators understand machine and process conditions quickly. We configure operator screens to present controls, process values, equipment status, alarms, system messages, and navigation practically.
We can also modify existing HMI screens when new equipment is added, PLC logic changes, additional process information is required, or screens need to be reorganized.
HMI Tag & Data Configuration
HMI tags connect screen objects with data from the PLC or other control equipment. Incorrect tag addresses, data types, scaling, or communication settings can result in missing, incorrect, or outdated information on the operator interface.
We can configure and review HMI tags used for process values, equipment status, commands, setpoints, counters, alarms, and other operating information.
HMI Alarm Troubleshooting & Configuration
HMI alarms help operators identify equipment faults, abnormal process conditions, warnings, and other events that require attention. Incorrect alarm configuration can cause missed alarms, unnecessary alarms, incorrect messages, or alarms that don't match the actual process condition.
We can check alarm tags, PLC signals, alarm messages, trigger conditions, communication status, and related HMI settings to identify and correct alarm-related problems.
HMI Trends & Process Monitoring
HMI trend screens can help operators monitor changes in process values and equipment conditions over time. Depending on the HMI platform and system requirements, trends can be configured for temperature, pressure, flow, level, speed, motor current, frequency, and other process information.
We can also review existing monitoring screens when process values are missing, incorrectly scaled, or difficult for operators to interpret.
HMI Backup & Configuration Recovery Support
Where the HMI platform, software, project files, and access permissions allow it, we can assist with HMI project backup, configuration review, parameter updates, and restoration support.
Maintaining an up-to-date HMI project backup can reduce recovery time if an operator panel fails, is replaced, or loses its configuration. Review existing project files before making changes to a working system.
HMI Integration with Industrial Automation Systems
HMIs often operate as part of a wider industrial automation system that includes PLCs, control panels, sensors, VFDs, soft starters, SCADA systems, and other field equipment. We configure and troubleshoot HMI integration so that operators can monitor equipment status, process values, alarms, and permitted control commands from the interface.
Our Industrial Automation & Control Services support complete automation systems where the HMI must operate with PLC logic, communication networks, field equipment, and industrial processes.
HMI Integration with VFDs & Soft Starters
HMIs can be configured to display operating information from VFDs and soft starters, depending on the automation system and communication arrangement. Operators may monitor motor status, operating values, alarms, and permitted commands directly from the HMI.
EMAN FTC also provides VFD installation and commissioning services and soft starter installation and configuration services for related industrial motor control requirements.
HMI Testing & Commissioning
After troubleshooting, configuration, or modification, we test the HMI with the connected automation system. Testing helps confirm that screens, commands, tags, alarms, process values, status indicators, and communication functions operate as intended.
✓ Screen navigation testing ✓ PLC communication verification ✓ Command testing ✓ Alarm verification ✓ Process value verification ✓ Status indicator testing ✓ HMI tag testing ✓ Final operating checks
Applications of HMI Systems
HMI systems are commonly used in manufacturing plants, production lines, pumping systems, HVAC systems, water and wastewater facilities, conveyors, motor control systems, process equipment, control panels, utilities, and other industrial automation applications.
