Tech Note 98: How to Set Up a Wonderware Historian Cluster

This tech note walks through the setup of Wonderware Historian 9.0 running on a Microsoft Windows 2003 cluster for high availability and failover purposes. By implementing a two or more node cluster, it allows avoiding extended downtime due to hardware failure by allowing the software to failover to a secondary node or other node in the case of failure of the active node.

Please note that this allows for high availability of the server and software but by itself does not provide true data redundancy.

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.

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...
