4.4.12.Map Descriptor Example 9 - Multistate Output (Zone and Area Machine)
A write to the Multistate Output Data Array which is shared by a BACNet IP Map Descriptor will execute one of multiple scripts. The multiple scripts are specified in the Data Array defined under “DA_Lut_List”. The value written into the Multistate Output Data Array is used as the offset into the Data Array defined under “DA_Lut_List” to retrieve a script number from the Data Array. Script numbers range from 0 to 65535.

The Multi_Scripts_Length field is used to indicate the maximum size of the Data Array specified under Data_Array_Name. One Map Descriptor per object must be defined with a Multi_Scripts_Length value of one or greater.
