■
Extend MFDO1 to MFDO3 Function Selection
You can set MFDO functions to bit 0 to bit 2 [MEMOBUS MFDO1 to 3] of MEMOBUS register 15E0 (Hex.).
Use H2-40 to H2-42 [Mbus Reg 15E0h bit0 to bit2 Output Func] to select the function.

Note:
• Refer to H2-xx "MFDO Setting Values" for more information about MFDO setting values.
• When you do not set functions to H2-40 to H2-42, set them to F.
■
Output of Logical Operation Results of MFDO
This enables the logical operation results of two MFDOs to be output to one MFDO terminal.
Use H2-60, H2-63, and H2-66 [Term M1-M2 Secondary Function to Term M5-M6 Secondary Function] to set the
function of the output signal for which logical operations are performed.
Use H2-61, H2-64, H2-67 [Terminal M1-M2 Logical Operation to Terminal M5-M6 Logical Operation] to set the
logical operation.
