Windmill 7 Logging, Charting and Control Software

Windmill Logger
Windmill Logger is capturing data from several channels.
Critical alarms are shown by a red background; warning alarms by blue.

Windmill data acquisition software is supplied free with the 750. This modular suite offers data logging, charting, alarm indication, output control and DDE links to other applications like Excel. You can also add process mimic generators, sequence control and many other modules. Should you wish to program the 750 yourself, you can use the IML Tools to do so.

Measure Analogue Voltages

The 16 single-ended voltage inputs let you measure voltages in the range ±10 V. The inputs are multiplexed by the software - passed in turn to the 750's amplifier. The resolution is 12-bits. This means that signals will be resolved down to 5 mV.

Switch and Read Digital Inputs and Outputs

The 750 provides 16 digital I/O lines, arranged in two groups of 8. Use Windmill software to choose whether each group is an input or an output. You can read or set the state of each line individually. Alternatively, you can switch several channels at the same time.

Count up to 65535

The Windmill 750 has eight 16-bit totalling counters. Each counter starts at zero and counts pulses to a maximum of 65535. You can reset a counter at any time from Windmill software. You can use the counters in one of two modes: accumulating count or resetting count. In accumulating count the counter keeps counting until you reset it. In resetting count the counter shows the number of pulses since the last reading.

Scale the counts to the engineering units of your choice in software. For example if the pulses came from a flow meter which produced one pulse for every 50 millilitres, a scale factor of 0.05 would give a reading in litres.

The counters are found on 8 of the digital input and output lines. You can use any of these you don't need for counting as normal digital inputs: the counts are always maintained even if you don't plan to use them.
