12.1 Types of Data
Types and roles of monitor data
The monitor data area in the buffer memory stores data relating to the operating state of the positioning system, which are
monitored as required while the positioning system is operating.
The following data are available for monitoring.
Monitoring the system
■Monitoring the positioning system operation history
*1 Displays a value set by the clock function of the CPU module.
Monitoring the axis operation state
■Monitoring the position
