- The sample map includes float32 flow and volume registers, a temperature-scaled integer, a heartbeat, and a writable stop command.
Field notes
The example map spells out process fields such as gross and net gallons, flow rate, temperature, density, alarm code, and heartbeat. The described simulator models four loading bays and two linked tanks, while the HMI editor is presented as a place to build gauges, charts, and controls against those devices.
