Honeywell HMI programming in Kenya: Experion HMI and operator stations

Honeywell Experion provides operator screens and SCADA for process plants and utilities. We create and modify Experion displays and integrate PLC data into Experion systems.

Honeywell HMIs we work on

• Experion PKS and Experion HS: process control and SCADA with HMIWeb displays

Software: HMIWeb Display Builder, Experion configuration tools. Networks: Ethernet, Modbus and OPC to controllers and PLCs.

Honeywell HMI services

• HMIWeb displays, alarms and trends
• Adding PLCs and new equipment to existing Experion systems
• Alarm rationalisation

What a good HMI screen should do

• Show the state of the machine at a glance, with clear colours for running, stopped and faulted
• Explain alarms in plain language, with the cause and what the operator should check
• Keep recipes, setpoints and counters in one place, protected by user levels
• Trend key values such as temperature, pressure, speed and energy
• Work in the language your operators use every day

How we approach an HMI project

1. Back up the existing HMI project and note the panel model and firmware.
2. Agree the screens with operators and supervisors: overview, detail, alarms, recipes and trends.
3. Build and test the project against the PLC tags, with simulation before going to site.
4. Install and commission on the machine, checking every button, value and alarm.
5. Hand over the project file, user passwords and a short operator guide.

Tips from our engineers

Fewer, better alarms

Too many alarms hide the important ones. Reviewing and grouping alarms makes operators faster in an upset.

Keep display standards

Consistent symbols and colours across displays reduce operator errors.
