I want to write a VBScript code which allow reading & writing Information from/to an AB PLC5 via a Wonderware DAS Server(DASABTCP). The DASABTCP can talk in 3 Protocols: NetDDE, SuiteLink and OPC.

Is there an object I can create or get within VBScript in order to accomplish my goal?

 

Hi - there is an OPC client component tool called OPC Data.NET

http://www.opcwebclient.com/html/opcdata_net.html

that can do what you want - sample script to use VBScript (i.e. Windows Shell Scripting) to connect to an OPC server at:

A free trial is available at:

You can write your own OPC client from scratch in VB. I have done this, but for the cost of commercial software to create client you may not find it worth it. If you need more info, email me.

Thanks for your reply. I'll have a look on your suggestions.
