Change the module name

The default module name consists of 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
 or PI server. The
FactoryTalk Historian ME
 module name is prepended to the
FactoryTalk Historian ME
 tag name to create the
FactoryTalk Historian SE
 or PI server tag name. This provides the tag with uniqueness and context.
Changing the module name may result in duplicate tags being transferred. When tags are transferred to
FactoryTalk Historian SE
 or PI server, they are appended with the module name. If the module name has changed, the tags will be transferred again with a different name, for example:
  • Tags from the module FTHME1 are being transferred to the server. When transferred, the module name is added to the tag name (for example, FTHME1.<tag_name>).
  • The module name is changed from FTHME1 to FTHME2. Consequently, the tags that have already been transferred will be transferred again because now their tag name is FTHME2.<tag_name>. These duplicate tags will be counted against your allotted number of points.
    TIP:
    You must have administrator privileges to change the module name.
To change the module name
  1. Click
    Advanced
    , and then click
    System Settings
    .
    The
    System Settings
     page appears.
  2. In the
    Module Name
     text box, enter a new name.
    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 name is limited by the following rules:
    • The name must not contain:
      • More than 64 alphanumeric characters,
      • Any special characters (such as !, @, #, $, %, ^,&,*).
      • Only digits.
      • Only the following expression:00000000-FTHME.
    • The name must be unique in relation to other FactoryTalk Historian MEs on the same network.
  3. Click
    Save
    .
    A message appears asking you to confirm that you want to proceed with the changes.
  4. Click
    OK
    .
    The module name is changed and the following message appears:
    INFO: The module name has been configured successfully. Please stop and start Data Transfer.
    TIP:
    The module name is also used as the DNS hostname of the module and should be unique on the network. The
    FactoryTalk Historian ME
     Module is not able to check the network for naming conflicts. You need to use the DNS Server to check for such conflicts. Contact your local IT administrator for more information.
