You can use any Cicode expression (or variable tag) as a trigger for a report. If the result of the expression (in the Trigger field) becomes TRUE, and if the Time and Period fields are blank, the report is run. For example:
Time |
|
Period |
|
Trigger |
RCC1_SPEED<10 AND RCC1_MC |
This report is only run when the expression (Trigger) becomes TRUE, i.e., when the digital tag RCC1_MC is ON and the analog tag RCC1_SPEED is less than 10. The expression needs to become FALSE and then TRUE again before the report is run again.
If you use the Time and/or Period fields, the trigger is checked at the time and/or period specified, for example:
Time |
6:00:00 |
Period |
1:00:00 |
Trigger |
RCC1_SPEED<10 AND RCC1_MC |
This report is run each hour, but only if the expression (Trigger) is TRUE (i.e., if the digital tag RCC1_MC is ON and the analog tag RCC1_SPEED is less than 10).
