I created an element template with an attribute and a child attribute as PI POINTS, as seen in the picture below.
The PI Points rule formation is "\\%Server%\%@Tag%.v" for "Verificado and "\\%Server%\%@|TagLimite%" for "Verificado|lsu".
"Tag" and "TagLimite" are string attributes.
Everything is fine when I access those attributes from PI System Explorer or when I use Analysis. However, in PI VISION, intermittently, I get the message:
The substitution parameter %@|TagLimite% is not being recognized and it happens only with the child attributes.
I tried to set "TagLimite" as indexed and configuration item, but I have been getting this strange message from time to time neverthless.
