4.9 Data Logging Settings
In addition to the Monitoring Function, MPLOGGER also has a data logging function. The data
logging function collects specified tag groups from the controllers at a specified time interval
and stores the data in a Microsoft Access MDB file. This function is useful for creating graphs
and daily or monthly reports for tags that require periodical sampling.
To use the data logging function, you need to determine which tag will be sampled at what inter-
val using the following settings.
1. Tag Group Settings
A number of tags are divided into and managed as tag groups. With MPLOGGER, the
time interval can be set for data collection for each tag group. The data values are stored
in the log database for each tag group. Tags with similar properties can be grouped
together.
2. Tag Settings
Defines the tags in a tag group. Tags used for monitoring can also be used for data log-
ging.
The following pages describe how to setup these settings.
