Target tag is an invalid tag

Possible cause and solution:
  • The tag scope is not compatible with the configuration.
    For the target tag to be valid it must be either controller-scoped or in the same scope as the input tag.
  • The target tag configuration is not valid for use with tag-based alarms.
    For the target tag to be valid it must meet the following criteria:
    • It must be configured with one of the following data types: SINT, INT, DINT, LINT, or REAL.
    • It cannot be a safety tag.
    • It cannot access extended properties such as Min, Max, or Engineering Unit.
    • It cannot have a bit index out of range.
    • It cannot have an array dimension out of range.
