2. Enter a Qualifier Block for ON/OFF Collection
State (Optional).
Specify an optional Qualifier block to collect data for a specific interval when process data has
changed. In the Qualifier field, enter the block name that determines when the data collection
state for the group is on or off. The Qualifier block is usually a Digital Input or Digital Output
block. A Digital Register block cannot be used as a qualifier block. When the digital block goes
from Open to Closed, data collection starts for the group. When the digital block goes from
Closed to Open, data collection stops.
If the qualifier block is a block other than a digital block, a value of 0 stops collection. Any value
other than 0 starts collection.
If a non-digital block is assigned as a qualifier, the following message appears: The qualifier is
not a digital point. Use anyway?
If a non-existent block is assigned as a qualifier, the following message appears: This qualifier
not found in database. Use anyway?
When starting Historical Collect, an operator message is generated warning that the qualifier is
not found.
To choose the qualifier block from a list of tag names for the node entered in the Node field
select the "..." button to the right of the Qualifier field.
The tag names for the node displayed in the Node field are shown in the standard Tag Select
dialog box.
