Proprty transfer aspect : Source expression
I was trying to test the proprty transfer aspect.....but the source expression showing invalid ....does any one can answer what is the mistake in expression...please see the attacheent.
Trying to transfer data from 3rd party opc server to AC800M....
I want to transfer 3rd party data x2(bool) to AC800M variable TestX2(bool)...
How to write the expression is not so clear in ABB documentation.
Seems you have an object named "Configured Aliases", which has a "Control Connection" aspect, containing the property "x2"... it seems to be ok so far.
However, the ":Value" at the end of your expression actually exceeds the final item possible. If "x2" is of a structured data type with a "Value" variable you should type "x2.Value", if it is just a bool as you mention, type "x2" alone, instead of "x2:Value".
Try using this syntax:
Note 1: Three parameters separated by two colon characters.
Note 2: OBJECT must be unique. Use Find Tool to tell (one singular match is required). Full path possible, but not mandatory. Partial path also OK. Hint: always verify with Find Tool.
