2.3 Settings for Using the Programmable Controller CPU Monitoring Function
(4) Setting items for sending monitoring results
The following is an example of setting items and data transmission when sending the monitoring results of the
programmable controller CPU monitoring function execution to the external device using the non procedure
protocol.
This example shows a case in which the D0 to D3 device information and user frame data are sent by the
edge trigger method using a condition of D0 = 0.
Perform the settings on the "PLC CPU monitoring system setting" screen and the "###" screen of GX
Configurator-SC.
