■Intelligent function module number of MELSECNET/H remote I/O station
Intelligent function module number of MELSECNET/H remote I/O station is the upper 2 digits of the last number represented
with 3-digit number of the following "Input/output signal based on the remote I/O station".
Specify this with "Input/output signal based on the remote I/O station" regardless of the contents of common parameters set in
the master station of MELSECNET/H remote I/O network.

Read data, write data
The read buffer memory value is stored for reading, and the data to be written is stored for writing.
This function reads/writes data in byte unit.
■Data communication in ASCII code
Handle a word data for one buffer memory address as 2-byte data.
Convert the value to 2-digit (hexadecimal) ASCII code per one byte, and send it from the upper digit.
■Data communication in binary code
Handle a word data for one buffer memory address as 2-byte data.
Send 2-byte numerical values from lower byte (L: bits 0 to 7).
Ex.
When the data for one buffer memory address is 09C1H
