usage : mbpoll [ options ] device|host [ writevalues... ] [ options ] ModBus Master Simulator. It allows to read and write in ModBus slave registers
connected by serial (RTU only) or TCP. Arguments :
device Serial port when using ModBus RTU protocol
COM1, COM2 ... on Windows
/dev/ttyS0, /dev/ttyS1 ... on Linux
/dev/ser1, /dev/ser2 ... on QNX
host Host name or dotted IP address when using ModBus/TCP protocol
writevalues List of values to be written.
If none specified (default) mbpoll reads data.
If negative numbers are provided, it will precede the list of
data to be written by two dashes ('--'). for example :
mbpoll -t4:int /dev/ttyUSB0 -- - -
General options :
-m # mode (rtu or tcp, TCP is default)
-a # Slave address (- for rtu, - for tcp, is default)
for reading, it is possible to give an address list
separated by commas or colons, for example :
-a ,,,: read [,,,,,,,]
-r # Start reference ( is default)
-c # Number of values to read (-, is default)
-u Read the description of the type, the current status, and other
information specific to a remote device (RTU only)
-t Discrete output (coil) data type (binary or )
-t Discrete input data type (binary or )
-t -bit input register data type
-t :hex -bit input register data type with hex display
-t :int -bit integer data type in input register table
-t :float -bit float data type in input register table
-t -bit output (holding) register data type (default)
-t :hex -bit output (holding) register data type with hex display
-t :int -bit integer data type in output (holding) register table
-t :float -bit float data type in output (holding) register table
- First reference is (PDU addressing) instead
-B Big endian word order for -bit integer and float
- Poll only once only, otherwise every poll rate interval
-l # Poll rate in ms, ( > , is default)
-o # Time-out in seconds (0.01 - 10.00, 1.00 s is default)
Options for ModBus / TCP :
-p # TCP port number ( is default)
Options for ModBus RTU :
-b # Baudrate (-, is default)
-d # Databits ( or , for RTU)
-s # Stopbits ( or , is default)
-P # Parity (none, even, odd, even is default)
- RS- mode (/RTS on after sending)
- RS- mode (/RTS on when sending) -h Print this help summary page
-V Print version and exit
-v Verbose mode. Causes mbpoll to print debugging messages about
its progress. This is helpful in debugging connection...
