In this example separate Map Descriptors are provided to store the Pre-Alarm, Alarm and Trouble States of all devices on loops 1 and 2.
// Client Side Map Descriptors

A different array is used for each state.
Another strategy could have been to
use the same array but vary the offset.
The Data Type describes which Map
Descriptor to use for each device state’s
storage. If the device state doesn’t match
one of these data types then the message
will be ignored.
Additional Map
Descriptors are required
for each loop.
When storing
device data, the
Cheet_Zone must
be set to None.
