Mark:
First, the new version of VisuPro (Version IV) will use standard local time, not daylight time. This means that during the year it will be off by one hour for 1/2 of the year. Second, the plant pc cannot have more then one version and copy of VisuPro running at one time. If it does then strange things happen. I will ask our SCADA people to make sure that Joe does not run more then one copy of VisuPro on any plant pc.

First a question about the new version. As I understand it, the new version is going to use "local time". Is this local STANDARD time or local time (taking Daylight Savings time into account)? The owner's representative indicated a preference for local standard time. Now for a couple of things Joe Thorpe at the site mentioned. He has observed that if two copies of visupro are running at the plant, then 10-minute data does not get written. Second if visupro (at the plant) has the errdev file open, then new data does not get written to the file. Are you aware of these observations? If not you might want to contact Joe Thorpe and see if he has additional examples, and do some kind of testing. These are probably issues with the way that Paradox locks files. Mark Fisher
