2.3 Settings for Using the Programmable Controller CPU Monitoring Function
(3) Contents of setting items
The data items to be set using GX Configurator-SC to use the programmable controller CPU monitoring function
and the setting contents are explained below.
(a) Cycle time units
• Designates the unit for cycle time ( Page 61, Section 2.3.1 (3) (b)) for reading information from the
programmable controller CPU using the programmable controller CPU monitoring function.
• The cycle time units and the cycle time designated using this unit can also be used as the transmission time
interval for constant cycle communication.
(b) Cycle time
Designates the time for one cycle when reading information from the programmable controller CPU in order to
perform programmable controller CPU monitoring.
(c) Programmable controller CPU monitoring function
Designates the timing (constant cycle transmission or condition agreement transmission) when
sending/notifying information on the programmable controller CPU monitoring results (device information/CPU
status information) to the external device.
• The time interval designated in data items of Page 61, Section 2.3.1 (3) (a) and Page 61, Section 2.3.1 (3)
(b) for reading information from the programmable controller CPU can also be used as the transmission time
interval for constant cycle communication.
• The conditions for condition agreement transmission are designated using data items of Page 62, Section
2.3.1 (3) (h) and Page 62, Section 2.3.1 (3) (i).
(d) Programmable controller CPU monitoring transmission measure
Designates the means by which the programmable controller CPU monitoring results are conveyed to the
external device.
• Data transmission
The device information and the programmable controller CPU status information are sent as the monitoring
results.
• Notification
Notification message is sent as the monitoring results.
(e) Number of registered word blocks, number of registered bit blocks
Designates the number of word device blocks (number of registered word blocks) and the number of bit device
blocks (number of registered bit blocks) registered in the Q series C24 as the target when performing device
data monitoring or transmission.
(f) CPU abnormal monitoring
Designates whether or not the Q series C24 monitors abnormality of the local station programmable controller
CPU (status monitoring) in the programmable controller CPU monitoring.
