Sampling Function; Period Specification; Scaling Function - Mitsubishi Electric MELSEC iQ-R Series User Manual

Sampling function

This function samples target data from the access target CPU module.
The data sampling methods are as follows. The sampling interval that can be specified differs depending on the data sampling
method.

Period specification

When the specified conditions are satisfied, the period to perform logging and the period not to perform logging can be
specified.
Events are monitored only during the period of the logging.
The conditions to specify period can be selected from the following and can be specified by combining multiple conditions.
 Data conditions
 Date range
 Time range
 Day of the week/Week of the month conditions
