The #AlarmList object enables the content of the alarm buffer of an #Alarm object to be displayed.
The following information (columns) can be displayed:
Parameters |
Description |
AlarmNo |
Alarm number as configured in the Alarm definition |

Date/time of the occurrence of the alarm (rising edge). |
AlarmOff |
Date/time of the going of an alarm (falling edge). |
