BRM Monitors I relays on a bit-by-bit basis.
●
Function
Reads the ON/OFF statuses of I relays that have been specified in advance by the BRS command.
• Before executing this command, the BRS command must always be executed to specify which I
relays are to be monitored. If no relay has been specified, error code 06 is generated. This error also
occurs if the power supply is turned off.
• 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 the checksum, do not include the 2-byte checksum command element in the command.

dn: read data to the extent of the number of bits specified by the BRS command (n = 1 to 16)
dn = 0 (OFF)
dn = 1 (ON)
The response is “0” when the status is OFF or “1” when ON.

Example: Monitoring the PV burnout status of the UT150L with address number 05
The following command monitors the PV burnout status (I0007) at address number 05.
(This command reads the statuses of the I relays specified by the BRS command.)
[Command] STX$+ “05010BRMD7” +ETX$+CR$
The ON/OFF status of the I relay is returned as the response to the above command.
[Response] STX$+ “0501OK191” +ETX$+CR$
I relay has been ON.
