Software: Windmill Test-Seq

Test-Seq interprets a file of commands and controls a test rig accordingly. It can send commands and data to other Windows programs, or directly to the hardware inputs and outputs. The command, or test sequence file is a text file which you can easily create in a text editor or word processor.

Some typical Test-Seq operations

• Monitor channels for alarms.
• Perform PID control.
• Display a dialogue box that lets the operator select the next action.
• Wait until a value from an input channel complies with that specified, for example Wait Temperature > 20.
• Change channel attributes, for example change the units of a temperature channel from Celsius to Fahrenheit, or the range of a voltage channel from ± 10 volts to 0-10 millivolts.
• Open a new file to log data every hour, day or week.
• Ramp output values up and down.

Test-Seq is an add-on to the Windmill suite, which offers logging, charting, hardware set-up, netDDE and process mimics. Other add-ons are available. Windmill runs under Microsoft Windows.
