Bit Masked Reads within the TOP Server
Is it possible to encode individual bits or boolean tags into a single integer value?
The Advanced Tags Plug-in can be used to combine individual boolean tags into a single integer value. This Derived tag will be structured similarly to the expression below:
2n*(BooleanTag(n+1))+...+22*(BooleanTag3)+21*(BooleanTag2)+20*(BooleanTag1)
*an example can be found in the attached project file


The resulting integer tag (MaskedRead) will be restricted to read only. The individual boolean tags will maintain the original Read/Write access.
More information on this configuration can be found the Application Note below, along with a sample project.
