The only valid data type for these tags is bit.
Once set, these status bits remain On until the condition has been
cleared. Warning messages are displayed on the terminal for the
corresponding conditions. The 100% warning message requires the
operator to acknowledge the condition.
Note: An ASCII Trigger application supports the HE Stack Status
tags. However the terminal returns the actual status number: 85, 95
or 100 to the controlling device, as part of the Ctrl-H command. See
Page 5–12 for the HE Stack report the terminal sends to the ASCII
Triggering device.
To enter these global status tags:
•
select the name of a tag from the list box, or
•
type a new tag name and select the Edit Tag button to define the
tag.
To edit a Status Tag attributes:
1. Put the insertion pointer in the tag box.
2. Select the Edit Tag button to bring up the Tag Form dialog:
3. Edit the tag’s attributes (see the section starting on Page 8–2).
4. Select OK.
Note: In an ASCII Trigger application, only a tag name is required
for HE Stack tags. Node name and address may be left blank.
