Tech Note 93: Brief Overview of New ArchestrA Graphic Features in Wonderware InTouch 10.1

Many users of InTouch managed or published applications have been utilizing the new ArchestrA graphics introduced with the release of Wonderware Application Server 3.0 and Wonderware InTouch 10.0. Recently Wonderware released new versions of each product as Wonderware Application Server 3.1 and Wonderware InTouch 10.1. As well as resolving a number of known issues (for more information please refer to the IAS 3.1 and InTouch 10.1 ReadMe documents) they also introduced some new features in regards to working with ArchestrA graphics.

This document is to help users understand and take advantage of the new features in order to get the

Tech Note 89: How to Implement Time Considerations with Wonderware Historian and IDAS Systems

When working with Wonderware Historian and IDAS, it is important to take time into serious consideration. With IDAS historical data storage there is a term called the "Real-Time Window", which is a period of time behind and ahead of the Wonderware Historian system time, where values coming into the system are considered "valid" and will be stored properly. With Wonderware Historian the real-time window can be any value coming into the system between -30 seconds and +999 milliseconds. Time offset and discarded data can be a result of improper time synchronization. The purpose of this document is to help identify

Tech Note 88: How to Modify Default Actions for ArchestrA Graphics

It may become useful to use an ArchestrA graphic for a purpose other than the original design. For example, say you like the look of the ArchestrA graphic titled "ButtonGlossyDotMomentaryOrange", but you want to use it for both a direct type action and then use the same graphic for a toggle type action. This document will relay a general procedure to accomplish this by using the preceding example.

Tech Note 87: How to use the ArchestrA Bulk Import utility to import Wonderware InTouch Tags

With the release of the ArchestrA Bulk Import Utility, it is possible to directly convert Wonderware InTouch tagnames into the ArchestrA IDE (Integrated Development Environment) as application objects. This tech note details the basic procedure required to perform this task with a select set of Wonderware InTouch tags under a single alarm group. Specifically, this example involves importing discrete and analog tags used to represent pumps and PID (Proportional Integral Derivative) control loops.

Please note that the procedure for larger applications or 3rd party HMIs may be more involved. For further details on using the ArchestrA Bulk Import utility please

Tech Note 86: How to Distribute WindowViewer Processes Across Multiple CPUs in Wonderware InTouch for Terminal Service Environments

When working in Wonderware InTouch for Terminal Service Environments it is the default behavior to lock all WindowViewer processes to the first CPU; however, it is fairly common for server class systems to have multiple core CPUs or even multiple CPUs. Wonderware has released the "InTouch Affinity Control" which allows system administrators to take advantage of the processing power, and distribute all of the client InTouch sessions across all available CPUs. This document will list the procedures necessary to install and utilize the "InTouch Affinity Control".

Tech Note 85: Configuring Automatic I/O Referencing Scripts in Wonderware Application Server 3.0

Wonderware Application Server 3.0 provides the ability to automatically assign object attribute I/O references via its scripting engine. The main benefit of using this feature is that a large quantity of PLC I/O references can be automatically configured during Runtime based upon the object instance name that has been assigned when creating instances. Effectively, by entering one name to represent the object in the process (e.g. name of pump, valve, transmitter, etc.), multiple I/O references can be automatically set to support communication to the object. This tech note provides the steps how to configure automatic I/O referencing script in Wonderware
