The Convert Tagname will convert OPC Item and Data Point names into WebAccess Tag names using conversion rules. The Convert Tagname will use the Item Name appended to Data Point Name plus the conversion rules in the OPCTol.ini file.
Users can modify this file to create new Name Conversion Rules.
The OPCTol.ini is located on the Project Node, typically at C:\WebAccess\Node\OPCTol.ini
A sample of the Version 3.0 OPC Tool INI file for the Barrington OPC Server is listed below.
Each section must be preceded by the official OPC Name in square brackets []. For example the Barrington OPC Server is named BarSys.OPCServer. The Section describing conversion rules for the Barrington OPC Server are in a section labeled [BarSys.OPCServer]
The rules are simple. Text
String OPC = Text String in Tagname. For example, Digital
Output.Channel=DO means convert the string "Digital Output.Channel"
into a tag name with DO.
It may take an experimental or test
database where you import OPC Items and DataPoints unchanged, then
create rules to automatically shorten them.
