-------------------------Monitor------------------------ The Newsletter for PC-Based Data Acquisition and Control Issue 73 www.windmill.co.uk August 2004 --------------------ISSN 1472-0221---------------------- Welcome to Issue 73 of Monitor. This month we're pleased to announce new software dedicated to counting people (or, in UK parlance, footfall counting). We also have the regular Excel corner and our tri-monthly listing of measurement and control exhibitions. We hope you enjoy this issue of Monitor , but should you wish to cancel your subscription you can do so at http://www.windmill.co.uk/newsletter.html CONTENTS ======== * Windmill News: New Dedicated People Counting Software * Excel Corner: Starting and Stopping Windmill Logger * Data Acquisition and Control Exhibitions ________________________________________________________ ________________________________________________________ Windmill News: New Dedicated People Counting Software ________________________________________________________ A year ago we announced that Windmill software had been chosen for a new people counting system (http://www.windmill.co.uk/monitor61.html). We now offer a program dedicated to counting people (or, in UK parlance, measuring retail footfall), which is easier to use for those who do not need the full capabilities of Windmill. The benefits of the new software include: - It can now communicate with the counting units over Ethernet, as well as over RS232, RS485 and modem links. - Users can now do everything from one program: setting up the counting units, downloading counts, viewing live counts and occupancy levels, and analysing footfall data. - The results can be imported into almost any third- party reporting software. Users are therefore free to use whatever software they wish to process the data and are not tied to the manufacturer's reporting software. - The software can handle counts from outdoors and thus be used for pedestrian counting. - It can perform calculations on the data, such as combining the count from several entrances.

It does this at regular intervals, every minute for example. You can instruct Logger to start logging in a number of ways, for example when: - your equipment sends new data; - readings cross one of your alarm thresholds; - you press the space bar on the keyboard; - you press the software Start button. Likewise you can tell Logger to stop logging when: - you press the software Stop button; - your chosen logging duration expires. However, there may be times when you would prefer to automatically start and stop Logger at pre-determined times. You can do this with the Windmill Test-Seq program (https://www.windmillsoft.com/daqshop/test-control.html) or with Excel. * Using Excel to Start and Stop Logger ==================================== If you want to use Excel to start and stop Windmill Logger, then you need to create a macro to do so. Here is an example of the code needed. Sub StartLoggerMacro() WaitTime End Sub Sub WaitTime() ' Waits until a time of day in 24 hour format - here 9.30 am and 0 seconds ' Then runs the StartLogger subroutine Application.OnTime Date + TimeSerial(9, 30, 0), "StartLogger" ' Waits until a time of day then runs the StopLogger subroutine Application.OnTime Date + TimeSerial(12, 45, 0), "StopLogger" End Sub Sub StartLogger() ' Starts the Logger program. See the Notes below. Shell "start c:\windmill\logger.exe demo1.wlg /AUTO" End Sub Sub StopLogger() ' Starts a DDE conversation with Logger ddeChan = DDEInitiate("Logger", "Commands") ' Sends the Destroy command to close Logger DDEExecute ddeChan, "Destroy" ' Ends the DDE conversation DDETerminate (ddeChan) End Sub Notes: 1. Replace c:\windmill\logger.exe with the path to your Logger program. 2. Replace demo1.wlg with the name of your Logger setup file.
