4.4.5.Map Descriptor Example #2 – QLA Report.

In this example, a Map Descriptor is created to read the Latest Area Report (QLA). This report contains gas concentration and status for each port and sensor. Ten Data array elements are required for each port / sensor that is reported. The poistion in the array is dependent on the port/sensor number. Appendix B provides additional information. By specifying the extra arrays (DA_Bit_Name and DA_Byte_Name) the driver stores additional information.
