    , but no tag has been assigned.
  • The message connection is assigned to an analog or digital tag and the alarm message being written out contains non-numeric characters.
  • The message connection is assigned to an analog tag and the message being written out is a numeric value outside the tag's maximum/minimum range.
  • The message connection is assigned to a digital tag and the message being written out is a numeric value other than 0 or 1.
