Map_Descriptor_Name, | Data_Array_Name, | Data_Array_Offset, | Function, | Node_Name, | Toshiba_Command, | Length, | Scan_Interval |
A1, | DA_AI_01, | 0, | RDBC, | Node_A, | OV1, | 1, | 5 |
For all commands except FAULT and ALARM, ensure that the Data_Array_Name points to an array of type float.
Make sure the Toshiba command supports the selected function.
For a list of commands, see Appendix A
All commands except ALARM and FAULT have length 1.

Map_Descriptor_Name, | Data_Array_Name, | Data_Array_Offset, | Function, | Node_Name, | Toshiba_Command, | Length, | Scan_Interval |
B1, | DA_DI_01, | 23, | RDBC, | Node_A, | ALARM, | 1, | 5 |
B2, | DA_DI_01, | 15, | RDBC, | Node_A, | ALARM, | 4, | 5 |
B3, | DA_DI_01, | 0, | RDBC, | Node_A, | ALARM, | 23, | 5 |
For ALARM and FAULT, use bit arrays
Use the offset to read a specific bit or start reading at a specific bit. Use in conjunction with length. Max value is 23.
Specify number of bits to read. Maximum for Offset + Length is 23.
