“#InTouch Tip: A query with syntax “\Intouch!$System” will retrieve alarms from within the console session or session 0 on a terminal server.

#InTouch Tip: Files such as InTouch.ini from managed applications can be accessed by selecting “File>Open Application Folder” in WindowMaker

#InTouch Tip: When using Network Application Development (NAD) remember to add the local working directory to the anti-virus exclusions list

Set 'Lock Window Size' in 'Special>Configure>WindowMaker' prior to changing an #InTouchapplication resolution to stop graphics being scaled

#ApplicationServer best practice: a target of 25,000 IO per platform is a good design maximum

#ApplicationServer tip: Engines are processes, they will not span a single core. Multiple engines will leverage multiple cores

#SystemPlatform: If the RMC connection fails then an engine will use the ArchestrA network to determine the status of its partner Wonderware

#ApplicationServer Tip: The security model and check in comments can be used to create a comprehensive log of changes for every object.

#ApplicationServer Tip: Each object has a change log, viewable through the object properties, which tracks who has been editing the object.

#ApplicationServer Execute scripts are called each time the AppEngine performs a scan and the object is On Scan

#ApplicationServer Startup scripts are called when an object containing the script is loaded into memory

#ApplicationServer Tip: For best performance aim for no more than 32 digital and 32 analogue field attributes on an object

Secondary data sources, store & forward and partnered #Historians are all great ways of preserving your data integrity.

#Historian Client Tip: Use an appropriate retrieval style to achieve the best combination of performance and clarity for your trends.

#Historian 2012 R2 supports up to 500,000 tags in tier-2 storage at a throughput of 125,000 values per second

#InBatch Best Practice: The InBatch BatchGUI ActiveX control should be embedded within an InTouch window which is never closed

#InBatch Best Practice: Implement a maintenance plan for the Batch History database. 2GB is the recommended maximum database size.”
