1.2 Module Configuration
The following illustration shows the module configuration of MPLOGGER.
When MPLOGGER is started, Excel loads the MPLOGGER Add-in Module as a hidden work-
book. Special MPLOGGER menus and dialogs are built into the Excel functions.
Any Controller link information in the cell settings is recorded in the Tag Database. The Add-in
Module coordinates this task.
Communications with the Controller is carried out by an independent module called the
MPLOGGER Data Communications Server. When the MPLOGGER is started, the server icon
appears in the windows task bar. It uses a cyclic procedure to periodically collect the data
defined by the Tag Database settings.
Part of the memory in the MPLOGGER Data Communications Server is dedicated to managing
the current values of each tag. Each cell in Excel uses a special OCX to display the current val-
ues corresponding to the server memory. The MPLOGGER Data Communications Server also
has a data logging function that collects and stores data in the Log Database for data logging at
specified time intervals.
This software package includes supplementary functions, such as Alarm Monitoring and Alarm
History Display Modules for communications errors.
