3.2.4 BRS Specifying I Relays to be Monitored on a Bit-by-bit

Basis

● Function

Specifies the numbers of I relays to be monitored on a bit-by-bit basis. Note that this

command simply specifies I relays. Actual monitoring is performed by the BRM command

after the I relay numbers are specified.

When the volume of data is large and you wish to increase the communication rate, it is

effective to use a combination of the BRS and BRM commands rather than just the BRR

command.

When the power is turned OFF, the register numbers specified will be erased.

• The number of registers to be specified 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 a checksum, do not include the 2-byte checksum command

element in the command.
