Let the MFAI function be assigned to MEMOBUS/Modbus register 15C1 to 15C3 (Hex.) [Mbus Reg 15C1h through 15C3h Input Function]. Use H3-40 to H3-42 [Mbus Reg 15C1h through 15C3h Input Function] to set the function and use H3-43 [Mbus Reg Inputs FilterTime Const] to set the input filter.

Note:
-
Refer to H3-xx “MFAI Setting Values” for the analog input setting values.
-
When you will not use the terminal, set H3-40 to H3-42 = F. The through mode function is not supported.
-
You cannot use H3-40 to H3-42 to set these MFAI terminals:
