Configuring the Module Name
The default module name has the FactoryTalk Historian ME module serial number
prepended to -FTHME. For example, A0003027-FTHME. This guarantees a unique
name, which is important when the module transfers data to a FactoryTalk Historian
SE server. The FactoryTalk Historian ME module name is prepended to the
FactoryTalk Historian ME tag name to create the FactoryTalk Historian SE tag name.
This provides uniqueness and context to the tag.
To change the module name:
1. Click on Advanced in the top navigation bar.
2. Click on System Settings in the left-hand navigation bar.
3. Enter a name in the Module Name field. The name should be descriptive enough
to make it easily identifiable. This is especially useful when transferring data to a
FactoryTalk Historian SE server. The module name is limited by the following:

Maximum of 64 alpha numeric characters in the name.

No special characters (e.g., !, @, #, $, %, ^, &, *) are allowed.

Must be unique in relation to other FactoryTalk Historian MEs on the same
network.
After entering a new FactoryTalk Historian ME name, click [Save]. FactoryTalk
Historian ME will automatically re-boot and generate a new login page after it
completes the re-boot cycle.
DNS H OST N AME
The module name is also used as the DNS host name of the module and should be
unique on the network. The FactoryTalk Historian ME cannot check the network for a
naming conflict. Use the DNS Server to check for naming conflicts. Contact your
local IT administrator for more information.
D UPLICATE T AGS
Changing the module name may result in duplicate tags being transferred. When tags
are transferred to FactoryTalk Historian SE, the tags are appended with the module
name. If the module’s name is changed, the same tags will be transferred again with a
different name. For example:

Tags from the module FTHME1 are being transferred to FactoryTalk Historian
SE. When transferred, the module name is added to the tag name (e.g.,
FTHME1.<tag_name>).
