About System Tags

Available starting in NiagaraAX-3.4, the System Tags property allows you to specify an additional identifier (the System Tag) to use with a history extension.

The System Tag identifier is specified as one or more string parameters under the History Config property of a History Extension (see Figure 176). Each string in a System Tag property must be separated by a semicolon. For example: NorthAmerica;Region1;Cities

This additional identifier is then available for selective import or export of histories using the Niagara System History Import or Niagara System History Export option from the Niagara History Import Manager or Niagara History Export Manager, respectively (see Figure 177 and Figure 178).
