5.3 MPLOGGER Data Communications Server
MPLOGGER has a Data Communications Server which is separate from the Excel Add-in
Module. It controls communications with controllers. The Data Communications Server will be
displayed in the Windows task bar as an icon.
The Data Communications Server has two main functions:
• Monitoring function: Preserves the new values of specified controller data.
• Data logging function: Periodically collects tag data and stores it in MDB files.
Before using these functions, the Data Communications Server must be activated for communi-
cations. The task bar icon is active when communications are active.
5.3.1 Activating and Disabling the Server
The Data Communications Server automatically starts when MPLOGGER (Excel Add-in
Module) is started. Similarly, when MPLOGGER is closed, the Data Communications
Server is also closed.
The Data Communications Server can be activated or disabled as a stand alone system. If the
data logging function is used more than the Monitoring function, there are situations where
activating and disabling the Data Communications Server on its own is advantageous.
The Communications Data Server is an independent application program. Double-clicking
MPLOGGER.EXE file in the MPLOGGER installation folder will launch the application,
and an icon will automatically appear in the task bar.
To close the application, right-click the icon and select Exit from the pop-up menu.
If the Data Communications Server is disabled while MPLOGGER is running, MPLOGGER will not
function properly.
