How to change the scan rate of the main driver worksheet?

Admin
I have read the user manual but the desciption doesnt make sense to me. Where do I edit the file? I tried adding it to the configuration settings file but it didn't work. What am I missing?
(From Manual)To adjust the rate, manually edit the project file
(i.e., projectname.APP) to add the following entry:
[Options]
MainDrvAlwaysTrigger=tagname
tagname can be either another system tag.

  • I'd recommend sticking with 'standard' driver sheets and use the 'Read Trigger:' to set a slower scan rate. I only ever use 'standard' driver sheets due the added control and feedback features they provide.

    There are some other techniques you can apply as well. For example, you can implement handshake arrangements to ensure that no scans are ever missed for processing. This probably isn't a requirement for your application ... but it has been for mine.

    If you need any further advice on possible scan control methods let me know ... as I have had to do a reasonable amount of work in this area.

    On reflection, a self pacing scan arrangement might be just what you need to prevent 'over scanning'. I can go into more detail later, but the basis for this approach is to toggle the 'Read Trigger:' tag on completion of tag processing. You also use the 'Read Completed:' tag to initiate processing of the worksheet tags.
