Setting up NiagaraNetwork history policy
On a regular basis, the
Supervisor station collects history data from its subordinate stations for archival purposes and to create reports. This procedure sets
up history policy properties on the NiagaraNetwork in preparation to import and export histories.
Prerequisites:
- The NiagaraNetwork is configured with at least two stations, such as a
Supervisor target (receiving) station and a remote (sending) controller station.
- A client connection is established between the two stations.
- The source station contains histories to be exported or imported.
-
Workbench is connected to the
Supervisor (target) station.
- To identify the stations from which to import and the names of the history files, expand , right-click NiagaraNetwork and click
This exposes the NiagaraNetwork configuration properties.
- Click History Policies or expand History Policies.
The History Network Ext (extension) opens.
- Click the Default Rule or expand Default Rule.
The
Config Rule Property Sheet opens.
This is the primary rule for identifying the histories to export from each remote station.
- Configure the
Device Pattern based on your device naming convention.This sets up in the Supervisor station the remote devices with history extensions. You may use the asterisk (*) as a wildcard
or enter a series of device tags each delimited by a semicolon (;).
- Configure the
History Name Pattern based on your history naming convention.This identifies the names of the histories in the remote station(s). You may use the asterisk (*) as a wildcard or enter a
series of history extension tags each delimited by a semicolon (;).
- Select a
capacity value and, if you choose Record Count, enter the maximum number of records to save.Unlimited assumes that your
Supervisor PC can store large quantities of history data.
Record Count limits the number of records to store.
Which option to choose depends on your unique situation and how frequently each remote station collects device and event data.
- If you selected
Record Count for capacity, choose a fullPolicy option and click Save.You do not need to choose a
fullPolicy option if
capacity is
unlimited.
Roll deletes the oldest records and replaces them with the newest.
Stop saves exported records until it reaches the total Record Count after which it stops saving records.
- To create another configuration rule, right-click the Default Rule, click Duplicate, give the new rule a name, click OK, expand the new rule and configure the four properties.
You need more than one rule to apply different device and history name patterns.
After setting up configuration rules it is time to create import descriptors.
