4.4.4. Reading TIWAY data map descriptor examples
4.4.4.1. Reading data from contiguous PLC data memory locations
Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Function, Node_name, TIWAY_Data_Type, Address, Length,
C01_RAW16_PLC01, RAW16_Data, 0, RDBC, PLC_01, IE_Ladder, 0, 10,
Scan_Interval
0s
The above map descriptor will continuously read 10 data elements starting from address 0 of type “IE_Ladder” from
PLC_01. The data will be stored in the data array called “RAW16_Data” from an offset of 0.

Scan_Interval
0s
The above map descriptor will continuously read 2 data elements from address 5 and 9 of type “Variable” from
PLC_01. The data will be stored in the data array called “RAW16_Data” from an offset of 10. The data will be
stored at offsets 10 and 11.
