Appendix A.19. Advanced Map Descriptor Example 10 - Show
One Map Descriptor is required for each point whose attributes you wish to ‘show’. The show function reads data that describes the
attributes and the state of each attribute for a single device. Every type of device has a different set of attributes. When the response
is received by the driver, it fills a number of Data Array locations with numeric values that represent the attributes and their states.
You should reserve at least 100 array locations for each Map Descriptor by setting the length to 100.
Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Function, Node_Name, Length, Scan_Interval sim4100_Func Sim4100_Card, Sim4100_Point, Sim4100_Sub
Show_mapdesc1, DA_SHOW, 0, rdbc, Node_A, 100, 1.0s, Show, 1, 2, 3
By way of example assume that point 1-2-3 is a Heat Detector and the response to the show query is as follows
40 Character Custom Label
Mx-y-2 HEAT DETECTOR
DEVICE ADDRESS: 7-10-2 TYPE: COMBO

The driver will load the array DA_SHOW starting at offset zero for up to 100 elements. Using the following tables we determine what
values you can expect for this response.
