mbmd write

Write register (EXPERIMENTAL)

Synopsis

Write writes a single register (holding, coil). Write will ignore the config file and requires adapter configuration using command line.

mbmd write [flags] register length value

Options

  -d, --device string     MODBUS device ID to query. Only single device allowed. (default "1")
  -e, --encoding string   Data encoding: bit|int|uint|hex|float|string (default "int")
  -t, --type string       Register type to write: holding|coil (default "holding")

Options inherited from parent commands

  -a, --adapter string     Default MODBUS adapter. This option can be used if all devices are attached to a single adapter.
                           Can be either an RTU device (/dev/ttyUSB0) or TCP socket (localhost:502).
                           The default adapter can be overridden per device
  -b, --baudrate int       Serial interface baud rate (default 9600)
      --comset string      Communication parameters for default adapter, either 8N1 or 8E1.
                           Only applicable if the default adapter is an RTU device (default "8N1")
  -c, --config string      Config file (default is $HOME/mbmd.yaml, ./mbmd.yaml, /etc/mbmd.yaml)
  -h, --help               Help for mbmd
      --raw                Log raw device data
      --rtu                Use RTU over TCP for default adapter.
                           Typically used with RS485 to Ethernet adapters that don't perform protocol conversion (e.g. USR-TCP232).
                           Only applicable if the default adapter is a TCP connection
      --timeout duration   Timeout for MODBUS communication (default 300ms)
  -v, --verbose            Verbose mode
