Overview

This library exposes a block interface for the Modbus protocol. This protocol is useful for many industrial application. The library handles many of the details under the hood, so the end-user can configure which modbus registers to read (master) or to write (slave). The library abstracts the details of the protocol into a simple block interface consisting of just a handful of blocks and configuration scripts.

Details

Modbus specification may be downloaded from (modbus.org): PI_MBUS_300

Modbus Master currently supports the following commonly used service(s):

  • 03 Read Holding Registers

Modbus Slave currently supports the following commonly used service(s):

  • 03 Read Holding Registers
  • 06 Preset Single Register

This library may be used on Raptor targets which expose a serial (RS232/RS485) interface such as the DISP-IMX286 (VEECAN) targets.
