‡
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]. The new module
name is saved. A dialog appears asking you to confirm that you want to change the
module name. If you are sure, click [OK]. After the name change takes effect, an
informational message appears at the top of the screen informing you that the
module's name has been changed and that you must now stop and restart data transfer.
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. 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 or PI server, 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 the server. When
transferred, the module name is added to the tag name (e.g.,
FTHME1.<tag_name>).
„
The module name is changed from FTHME1 to FTHME2. Because of this, the
same tags that were already 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.
Configuring Network Settings
Working with network settings may require your local network administrator’s
expertise. Contact your IT department for assistance if you need help.
