19.4.4 Get script startup trigger

This section explains how to use the get_exec_trigger() function of eventmonitor module to acquire the cause of its own activation (event generation in the case of an event activation script) from a running script.

(1) Script File Example

(1) Script File Example

The following is an example of a script file that acquires the activation factor (occurrence event) of an event activation script.

Import the module.
Calls a function to acquire the activation factor (occurrence event).
Determines whether the script activation factor is the applet function (event startup script).
Obtains the monitoring condition when the activation factor is timer monitoring.
Obtains the monitoring conditions when the activation factor is the operation message monitoring and information about the operation message that caused the activation.
