Last issue’s TechTip explained the Wonderware Base Template Library (BTL) and how it can be configured to assist in the automatic referencing of I/O in your Wonderware Application Server system. This issue’s TechTip will discuss a common architecture challenge and how the BTL can be applied in those situations. If you have not read the
If you have dealt with a Wonderware System Consultant when first developing a System Platform implementation, you may be familiar with the Base Template Library. The library is a set of objects, developed by the North American System Consultants group, that allows the developer to set up automatic addressing with a few simple UDA settings.

This Tech Tip describes how to calculate statistics on tags in Wonderware InTouch, assuming those tags are being historized in InSQL Historian 9.0. The statistic functions provided in this application are Min, Max, Avg and StDev. For the Min, Max and Avg calculations, the queries take advantage of the advanced retrieval modes provided by Historian
When designing, implementing, or troubleshooting a system, it is always useful to have the total number of items being polled from a given DI Object. The total number of I/O being polled by a DI Object, if excessive, can lead to system instability/poor performance. As many implementations of System Platform, including those using the Base
Wonderware’s Industrial Application Server allows the developer to import and install custom .NET libraries developed in Microsoft Visual Studio to be used by objects in the galaxy. There may be occasions where a developer would want to remove the libraries they installed from the galaxy repository. The following article explains two ways to do this,
