Point log storage enable conditions
Overview
Figure 53 shows examples of Point Log Storage Enable conditions.
Notice that it occurs unless Point Log Disable or Data Storage Disable is selected.
For Batch Point Log storage, notice that all three enables must be on.
The figure shows that storage does not actually occur until the Start Time occurs, and then at every Storage
Interval thereafter.
For On Command Point Log storage, notice the samples are taken the instant Point Log Enable is enabled
but not at intervals.
