Monitor: 200 Issues of Articles

Web link: Monitor Index

We've covered a lot of subjects in our 16 years - here are links to the main articles in each issue - hope you find it useful.

The subject index shows the progress of technology. For instance, our issue on communications between computer and instruments in 1998 made no mention of wireless networks. These didn't become popular for data acquisition until some years later.

Many of the articles though, are still as relevant now as when we wrote them.

You may reprint any of our articles providing you credit the author (Windmill Software unless otherwise stated) and place a link back to the source on the Windmill web site.

Questions on Using Windmill

Web link: Download Data Logging Software

Question

I am trying to file date log from a USB-to-RS485 converter. I use the ComDebug without problem communicating with the converter. How do I log the data into a text file based on specific interval (say about every 1 minute)?

Answer

You can use either ComDebug or Windmill Logger to collect data. With ComDebug

  1. Select the File menu and enter the name of the file to which you want to save the data.
  2. Click Sample Rate to choose the speed of logging.
  3. Click Start to log data.

To use Logger.

  1. If you haven't already done so, run ConfIML then SetupIML to create and save a hardware setup file (*.ims).
  2. Run Windmill Logger and load the hardware setup file.
  3. Select Settings from the Menu bar and enter your sampling interval.
  4. Press the Start button (or choose to log on alarm or when new data arrives.

Scientists testing use of free vehicles for lower-cost ocean exploration

First developed in the 1930s, free vehicles are untethered ocean sensor packages that are deployed from ships and collect valuable information about the ocean environment in areas that are difficult for humans to access. Until recently, the extreme pressure at the deepest parts of the ocean and limitations in buoyancy technology prevented free vehicle use in these areas. Recent developments in ceramics have changed this.
