command line utility to communicate with ModBus slave (RTU or TCP)


mbpoll uses libmodbus (http://libmodbus.org/). Although the syntax of these options is very close modpoll proconX program, it is a completely independent project.

mbpoll can:

 - read discrete inputs
 - read and write binary outputs (coil)
 - read input registers
 - read and write output registers (holding register)

The reading and writing registers may be in decimal, hexadecimal or floating single precision.
