Using the Add Points Wizard
To start the wizard, click Manage Points in the top navigation bar, then click the Add
Points Wizard
in the left navigation bar. The Add Points Wizard guides you through
the process of discovering and collecting tags in controllers, creating points, and then
storing the data from the controller in the FactoryTalk Historian ME. You can create
a maximum of 2500 data points per FactoryTalk Historian ME.
Do not use the web interface or the FactoryTalk Historian SE System Management Tools
(SMT) Tag Configurator to change the configuration or points when the module is
collecting data or data interruption may result.
Never delete the FTMEScanRateDefinition tag or other system-generated tags with
names such as “bae9cf24-c8b3-46c0-ad5d-a64df2174ed9” and values such as “No Data”.
The FTMEScanRateDefinition tag is a system-generated tag that contains scan class
definitions. If it is deleted all scan class definitions will be removed. Deleting other system-
generated tags will cause the System Log to overflow with error messages.
Every time point configuration(s) are changed you should expect data interruption.
