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.
4.4.4.2.Reading data from random PLC data memory locations
Map_Descriptor_Name, | Data_Array_Name, | Data_Array_Offset, | Function, | Node_name, | TIWAY_Data_Type, | TIWAY_Address_List, | Length, |
C02_RAW16_PLC01, | RAW16_Data, | 10, | RDBC, | PLC_01, | Variable, | 5 9, | 2, |

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.
4.4.4.3.Reading Drum_Count_Preset data from contiguous PLC data memory locations
Map_Descriptor_Name, | Data_Array_Name, | Data_Array_Offset, | Function, | Node_name, | TIWAY_Data_Type, Address, | Length, |
C08_RAW16_PLC01, | RAW16_Data, | 70, | RDBC, | PLC_01, | Drum_Count_Preset, 0, | 5, |
