4.5.11. Map Descriptor Example 11 – Alarm Ack
This example illustrates a Map Descriptor which can be used to acknowledge / silence or reset the panel. Read Appendix A.6 to
understand the limitations of this functionality. The value of the array element at offset zero in the array named DA_ACK is used to
send a signal to the Cheetah panel.
Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Function Node_Name, Cheet_Func
Ack_Mapdesc, DA_ACK, 0, Passive, Node_A, Port Response
This tells the driver
that this Map
Descriptor is to be
used for
acknowledging
alarms.
The Map Descriptor
must always be
passive. This is
because this Map
Descriptor is used to
respond to the port
supervision query.
Only one element of this
Data Array is used.
The value determines how
the Cheetah panel will be
affected.
If bit 0 is set then the panel
will be reset.
If bit 1 is set then the panel
will be silenced.
If bit 2 is set then the panel
will be acknowledged.
