NiagaraSystemHistoryExport defines the “system tags” text patterns used to export local Niagara histories into the target NiagaraStation, in addition to other export parameters including collection (“push”) times and current status. Along with NiagaraHistoryExport descriptors, NiagaraSystemHistoryExport descriptors reside under the History extension of a NiagaraStation in the NiagaraNetwork. However, SystemHistoryExport descriptors utilize “System Tags” properties of local history extensions, instead of unique history IDs.
