The above map descriptor will continuously write data of type “Loop_Gain” to 2 PLC data memory addresses of 5
and 9. The data to write will be collected from the data array “FLOAT_Data” from offsets 0 and 1.

The above map descriptor will continuously write data of type “Drum_Count_Preset” to 5 PLC data memory
addresses. The data to write will be collected from the data array “RAW16_Data” from an offset of 70. The Preset
Steps associated with the addresses are (address 0):5, (address 1):8, (address 2):9, (address 3):33, and (address
4):49.
