List of alarm properties
- Variable: after you add an alarm to the table, double-click this property to display a list of bool variables to which you can assign the display of an alarm state
- Alarm text: this property assigns the string displayed on the pages when the alarm is active. Click on the box allow to use the languages dialog; using this you can select or add a text.
- Alarm type
Double-click Alarm Type to display the alarm levels menu.
Level n selections belong to the Alarms category while the Warning selection belongs to Warnings.
There are 15 priority levels for alarms, used by the operator panel when active alarms are displayed.
Therefore, if all active alarms cannot be displayed simultaneously on the alarms panel (due to lack of room), a choice is made based on the chosen level: level 0 has priority over level 1 and so on until level 15, which is the least important in terms of priority of display. - Auto ACK
This property refers to acknowledgement of the alarm when it deactivates.
Double-click the property to select:
false – invokes the acknowledge function when the alarm deactivates (consult the System Functions paragraph to manage the alarms described below).
true – does not invoke the acknowledge function when the alarm deactivates.
Summing up:
If variables ALARM1, ALARM2, ALARM3 shown in the table switch their status from FALSE to TRUE simultaneously, the operator panel will display the texts alarm01, alarm02 and alarm03; since the ack property is true, these texts disappear without any operator action when variables ALARM1, ALARM2, ALARM3 switch their status from TRUE to FALSE. - At the end of integration of variables is necessary to recompile the PLC and then GF_Net (hardware), send it again to the target and make a reboot. If you use already existing variables you must recompile GF_Net (hardware), send it again to the target and make a reboot.
