Automating M&C tasks

Windmill Software has  a major new version of its Test Sequence software. Test Sequence automates measurement and control tasks by running a text file of commands. No programming knowledge is required.

The new version adds many new commands, making Test Sequence even more powerful. For example, it can now loop several times through a command sequence; check if a condition is true and act accordingly; wait until a specified amount of data has been collected; show instructions to a user and let a user manually adjust analogue outputs.

Test Sequence understands a total of 47 commands, all specifically for data acquisition and control. Combining these commands lets Test Sequence, for example, perform PID (proportional-integral-derivative) control; watch for alarms and take appropriate action; send key-presses to other Windows programs like Excel; start and stop data logging according to conditions or time of day; change the speed of sampling when alarm thresholds are crossed and ramp values up and down over time.

Test Sequence runs under Windows 7, Vista, XP, 98 and 95. It requires a Windmill 7 hardware driver which lets Test Sequence work with almost any RS-232, RS-422, RS-485 or Modbus device. Test Sequence also handles USB and Ethernet hardware. The new version of Test Sequence is currently reduced to 60 Euro.
