Chapter 2 Configure the 1757-ABRIO Module
Create a Tag
If you are planning to use automatic digital tags via a scheduled
connection to the 1757-ABRIO module from a ControlLogix controller,
do not create tags. Refer to
Scheduled Digital I/O Connections in
RSLogix 5000 Programs on page 60 . For all other tag types (analog,
text) and unscheduled connections, tags must be manually created.
To create a tag, complete the following steps.
1. Select the appropriate tab for the type of tag you want to create.
2. Right-click the root of the tree in the tag area and select Add
Tag.
The Add a Tag dialog box opens.
3. Type a tag name.
Tag names can be from 1 to 32 characters in length and must be
unique.
4. Type a message timeout time.
This is the time during which the host controller must update
the tag. The range of values is from 100 to 15000 ms. The default
is 5000 ms.
If the message timeout is exceeded, the tag times out and the
1757-ABRIO module takes the appropriate action.
5. Click OK to accept the tag.
You can create a maximum of 64 tags, of any combination of
types.
