6.3.3 Map Descriptor Example 1 Server using Data Array:
The following Map Descriptor enables this Driver to send data for all 8 sensors to the Node (DEV1) connected at the FieldServer. Refer to Section 4 for the
Data Array format.
The Driver can send Gas value messages, Alarm messages, Trouble messages and lock point messages. The driver can also be locked to send data for only one
particular sensor. In this example, if a valid (1-8) sensor number is inserted at offset 0 in the Data Array DA_CTL_R1, the driver will only send data for that
particular sensor. To disable the lock, insert an invalid (0 or >8) number.
