7. If necessary, edit the Scan Frequency and Scan Class values.
Item Description

Scan Class # Associated with the Scan Frequency value. If there is no
interface defined, the Scan Class # will be displayed without
a time period.
8. Click Apply.
Note that in this example the API Hostname is localhost, which
means that the interface will be configured to communicate with the
local FactoryTalk Historian SE server.
If you want the interface to communicate with a remote
FactoryTalk Historian server, you need to:
1. Add the remote server to the Connection Manager (page 19).
2. Define the remote server as the API host (page 19).
NOTE
This step is required to ensure connection to the correct remote
server.
Once you have added the server to the Connection Manager and
defined it as the API host, you can select the server from the API
Hostname list on the General page in the ICU.
There are additional parameters available for configuring the
interface:
• /MultiCOM
• /uiDll
• /FTDirectory
• /FTContext
To view them, click FTLDInt in the left pane of the dialog box.
