4.4.4 Map Descriptor Example

In this example two map descriptors are provided. The first reads Device 11 ( a Series 2 device) and obtains the Alarm Table. The second map descriptor reads Device 23 ( a series 9 device) and reads the Cooling analog output (2nd element of table 10).

Any name that is meaningful to you. The driver validates map descriptors and reports errors referring to the map descriptor name.

The first element from table 11 will be placed in element 220 (the 221st element) of the array

ALARMS.

The node names point the driver at a Node definition which specifies a port and a device address.
