Delta HMI programming in Kenya: DOP-100 series touch screens

Delta DOP touch screens are a popular low-cost HMI for machines and pump panels. We create and modify DOPSoft projects and connect them to Delta and other PLCs and drives.

Delta HMIs we work on

• DOP-100 series: touch screens from 4.3 to 15 inches
• DOP-B series: older terminals we maintain and replace

Software: DOPSoft. Networks: RS-485 and Ethernet to Delta and many other PLCs and drives.

Delta HMI services

• New screens, alarms and recipes
• Direct HMI control of Delta drives without a PLC on small systems
• DOP-B to DOP-100 replacement

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

Talk to drives directly

On small pump systems, a DOP HMI can control Delta drives over RS-485 without a PLC.

Save the project, not just the download

Keep the DOPSoft project file; it is much easier to edit than a recovered download.
