JScript version of OPC-DA Write multiple values, specify requested data types

25 Jul 2025 22:15 #14339 by Kyle.Oshima@caltrol.com
Have evaluation install of QuickOPC for development of custom application OPC interface with DCS platform -- initially installed as OPC Studio 2024.1, later recently uninstalled (per website instructions) and reinstalled as latest OPC Studio 2025.1

Have recently successfully proven suitable QuickOPC OPC UA solution for our needs, and in process of proving comparable OPC Classic conversion solution; however, am now unexpectedly encountering following error with OPC DA (see screenshot below)  Please advise what steps needed to resolve OPC DA variant -- OPC UA variant appears to work fine, and OPCLabs' EasyOPC-DA (COM) Demo Application works fine.  Also with prior 2024.1 version, do not recall having to tweak anything outside of standard install, was able to connect to same DCS OPC DA server with OPCLabs' VBScript examples without such error.

Also am looking for JScript version of Examples - OPC Data Access - Write multiple values, specify requested data types available in online documentation similar to separate inquiry for OPC UA -- see attached .zip file containing .js file as well as rudimentary .asp file to run JScript in web browser based on additional code details provided ( #14332 )
