BRW Writes data into I relays on a bit-by-bit basis in random order
● Function
Writes ON/OFF data into the individual I relays specified in random order by the specified
number of bits.
• The number of bits to be written into at a time is 1 to 32.
• For the format of response in the event of failure, see subsection 3.1.2.
• The command shown below includes the checksum function.
When performing communication without checksum, do not include the 2-byte
checksum element in the command.

Write data 0 and 1 indicate OFF and ON respectively.
Command (continued)
dn: write data of the specified number of bits (n=1 to 32)
dn=0 (OFF)
dn=1 (ON)
● Example:
Setting the four user-defined flags (I0033, I0034, I0035 and I0036) of the M Series with
address number 05 to ON, OFF, OFF and ON respectively.
