
BRR Reading I relays on a bit-by-bit basis in a random order

Function
Reads the ON/OFF status of the individual I relays specified in a random order by the
specified number of bits.
• The number of bits to be read at a time is 1 to 32 (decimal).
• For details on the response format at an error, see “3.2.3 Configuration of Response.”
• The command/response shown below includes a checksum function. When performing
communication without the checksum, do not include the 2-byte checksum element in the command.


BRW Writing data into I relays on a bit-by-bit basis in a random order

Function
Writes ON/OFF status in the individual I relays specified in a random order by the
specified number of bits.
• The number of bits to be written at a time is 1 to 32 (decimal).
• For details on the response format at an error, see “3.2.3 Configuration of Response.”
• The command/response shown below includes the checksum function. When performing
communication without the checksum, do not include the 2-byte checksum element in the command.
