overview
Here we will explain how to set up the event itself to be switched depending on conditions.
As an example, prepare two Periodic event (one with a 1 second cycle and one with a 10 second cycle), and enable/disable each event by setting "U01.F01.T01" to ON/OFF.
While "U01.F01.T01" is ON, event "E02" is enabled, and while OFF, event "E03" is enabled.

Setting contents
Tag configuration
Set the bit tag that will trigger the event to be enabled or disabled.
Here, set it to "U01.F01.T01".
Action Settings
Add a script action "A01" and set the script as follows:
//Event/E02!Enable = U01.F01.T01 //Event/E03!Enable = Not U01.F01.T01 |
In other words, when "U01.F01.T01" is TRUE, E02 is enabled, and when it is FALSE, E03 is enabled.
Event Settings
Add Tag event "E01" and Periodic event "E02" and "E03".
E01:
•Tag "U01.F01.T01"
•Comparison condition "Tag value changed"
•Execution action "A01"
E02:
•Set the period to 1 second
•Check "Disable" to disable the initial state
E03:
•Set the period to 10 seconds
•Check "Disable" to disable the initial state.
Commentary
▪When bit is ON
1.When U01.F01.T01 becomes TRUE, Tag event "E01" occurs and script Ver1 action "A01" is executed.
2.In "A01", the formula "//Event/E02!Enable = U01.F01.T01" is executed, and the event "E02" is enabled.
3.At the same time, the formula "//Event/E03!Enable = Not U01.F01.T01" is executed, and the event "E03" is disabled.
▪When bit is OFF
1.When U01.F01.T01 becomes FALSE, Tag event "E01" occurs and script Ver1 action "A01" is executed.
2.In "A01", the formula "//Event/E02!Enable = U01.F01.T01" is executed, and the event "E02" is disabled.
3.At the same time, the formula "//Event/E03!Enable = Not U01.F01.T01" is executed, and the event "E03" is enabled.
*In the script, "Not" reverses TRUE/FALSE.
