Tank Level Visualization - Wonderware-intouch Typing CST Test
Tank Level Visualization — Wonderware-intouch Code
Visualize a tank level using a bar graph linked to a tag.
# wonderware_intouch/demo/TankLevel
1. Create a Float Tag 'TankLevel'.
2. Drag a Bar Graph object onto the window.
3. Bind Bar Graph value to 'TankLevel'.
4. Add min/max animation: 0 = empty, 100 = full.
5. Optionally, add color changes based on levels.
6. Run runtime to see the tank level update live.Wonderware-intouch Language Guide
Wonderware InTouch (now AVEVA InTouch HMI) is a graphical Human-Machine Interface (HMI) development platform used to design real-time industrial visualization, SCADA dashboards, and operator control screens for manufacturing, utilities, and automation systems.
Primary Use Cases
- ▸SCADA dashboards and operator control panels
- ▸Real-time process monitoring
- ▸Alarm and event visualization
- ▸Historical trending and data logging
- ▸Multi-PLC and multi-protocol SCADA integration
Notable Features
- ▸SmartSymbols and reusable graphics
- ▸Built-in alarming and trending
- ▸Scripting using QuickScript
- ▸Connectivity via OPC, Modbus, DDE, SuiteLink
- ▸Integration with Historian and System Platform
Origin & Creator
Originally developed by Wonderware Corp. (founded 1987), later acquired by Invensys and now part of AVEVA.
Industrial Note
Extremely common in SCADA environments where operator monitoring, industrial visualization, and centralized control are required-especially in water treatment, power distribution, and manufacturing plants.
Quick Explain
