BRS Specifies I relays to be monitored on a bit-by-bit basis
● Function
Specifies the I-relay numbers to be monitored on a bit-by-bit basis. Note that this com-
mand simply specifies I relays. Actual monitoring is performed by the BRM command after
the I relay numbers are specified by this command.
When the volume of data is large and you wish to increase the baud rate, it is effective to
use a combination of the BRS and BRM commands rather than just the BRR command.
If the power supply is turned off, the specified I-relay numbers will be erased.
• The number of I relays 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 checksum, do not include the 2-byte
checksum element in the command.
