Note: You can create a maximum of 2500 data points per FactoryTalk
Historian ME Module. If you exceed 2500 data points, the Create button
will automatically become deactivated. The Create button will
automatically become reactivated when the point count is less than 2500
data points.
Follow these steps to create points in FactoryTalk Historian ME:
1. Select the tags from which you want to create points.
Select the tags you want to create by checking the box next to
the tag name. To select all tags in the list, Check the All/None
checkbox.
2. Click [Create].
Name This column displays the name of the tag
found in the ControlLogix Controller. The
tag name is a combination of the
ControlLogix project name added as the
prefix to the controller tag name.
Type This column displays the ControlLogix
datatypes for the tags. See Datatypes in the
FactoryTalk Historian ME User’s Guide
for more information.
Rate (sec) This column displays the current scan rate
in seconds for each tag. To change the scan
rate, click the Select checkbox next to the
tag(s). The Change Scan Rate button at the
bottom of the page becomes active.
Choose a new scan rate from the drop-
down menu located next to the Change
Scan Rate button. All selected tags will
change to the new scan rate.
Path This column displays the path to each tag
in the device. The path is a combination of
the ControlLogix Project name and its slot
location (CIP path).
