Allows controlling the usage of OPC's default interfaces by E3's OPC client. The available options are the following:
•0 - AnyVersion: Normal operation, default and recommended, the OPC Driver communicates with both DA 2.0x and 1.0a servers, with preference to 2.0x interfaces
•1 - Version10A: Allows forcing a communication with DA 1.0a standard for servers that support both DA 2.0x and 1.0a
•2 - Version20: Allows forcing a communication only with OPC DA 2.0x standard
This property cannot be modified when OPC client communication is enabled, both in E3 Studio and at run time.
NOTE |
Only as a last resource a Driver can be configured with a value different from 0 - AnyVersion. This property is for advanced usage only, and applies strictly to overcome a possible incompatibility situation with specific OPC servers. |
