Period for a Computed tag: The period does not influence the frequency or number of output values written by the Computed Tag job itself, only when the calculation will run. The frequency and number of output values written by the Computed Tag job depend on the input variable(s) frequency and number. For example, a job with a Period set to 24h will run every 24 hours. If the data uses input tags sampled every minute, then it will write values every minute. Each time the job runs, it looks to see the last output value and continues the calculation from that point. Therefore, if the job last ran 24 hours ago, it will write an output value every minute (for minute sampled data) for the last 24 hours. The resulting calculation does not depend on the period.
Put the Class name, this indicates the type of job:
Computed tags: be.pepite.pepito.data.historian.tm.jobs.ComputedTagTask
Exports to Analytics: be.pepite.pepito.data.historian.tm.jobs.ExportToAnalyticsTask

Note on DMFF file the will replace an existant DMFF both with the same name. This means that if the same file is used in two different Analytics projects (for example, if you create a copy of the project) and if the DMFF is updated in only one project, but both projects have the same file name, the DMFF file will be automatically updated in the other project too. |
