4.7.6 Testing the alarm system
1. Press [F5] to start the project, click the FAlarm button and set the four switches
Msg1 to Msg4.
– All four alarms are shown in the alarm list·
– In the alarm line, the "Msg4" alarm is shown. This is the currently active alarm
with the highest priority in the system.
– The "MessageState" variable shows the status "0100" (binary) for each alarm. If
necessary, this status can also be signalled back to the control system.
2. Reset the four switches Msg1 to Msg4.
– In the alarm list, the alarms are retained. However, the status changes and
therefore the colour as well. Due to the type of acknowledgement selected,
acknowledgement is necessary in order to finally reset the alarms.
– The status bits of alarms and alarm groups now show the status "0010".
3. Acknowledge the alarms one after the other by double−clicking the corresponding
entry in the alarm list.
– The alarms then disappear from the alarm list.
– The status bits in "MessageState" are also reset.
4. Set the four switches Msg1 to Msg4 again and then click the two key control
elements.
The contained alarms are all acknowledged together by means of the
acknowledgement bit of a group.
