The above map descriptor will continuously read the three status values from PLC_01. The status values are
defined as follows and will be stored in the data array contiguously from an offset of zero:
Status element 1 (DD) : Operational Status
Status element 2 (EE) : Auxiliary power source status
Status element 3 (FF) : NIM Operational Status
Please refer to the TIWAY systems manual for operational values and their meanings.

The above map descriptor will continuously write data of type “Control_Register” to 10 PLC data memory
addresses. The data to write will be collected from the data array “RAW8_Data” from an offset of 20.
