5.3.6 Map Descriptor Example 3 – Handling BITs
This example writes data from the FieldServer Data Array called DA_AO to the PLC identified as NODE1. The write is repeated every 5 seconds. Ten word values are
written to the PLC’s %AQ Data Table starting at location 20.

The format parameter tells the driver to override the default
data type and read Bits specifically. In this case the Bits are
stored in the Data Array in two separate elements at DA_T[100]
and DA_T[101]
