BRW Writes data into I relays on a bit-by-bit basis in a random order.
●
Function
Writes ON/OFF statuses into I relays at intervals of the specified number of bits on a per-I relay basis
and in random order.
• The number of bits to be written at a time is 1 to 16.
• 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 a checksum, do not include the 2-byte checksum command element in the command.

Example: Setting four user-defined flags of the UT150L with address number 05 to ON, OFF,
OFF, and ON.
The following command sets the four user-defined flags (I0025, I0026, I0027, and I0028) at address
number 05 to ON, OFF, OFF, and ON respectively.
[Command] STX$+ “05010BRW04I0025, 1, I0026, 0, I0027, 0, I0028, 181” +ETX$+CR$
Note: The user-defined flags (I relays) are flags that the user can freely read/write. For areas available
to the user, see Chapter 6, Functions and Applications of I Relays.
“OK” is returned as the response to the above command.
[Response] STX$+ “0501OK60” +ETX$+CR$
