Modbus tcp simulator linux

Presentation

mbpoll is a command line utility to communicate with ModBus slave (RTU or TCP). It uses libmodbus ⟨http://libmodbus.org/⟩. This is a multiplatform project, the compilation was tested on GNU Linux x86 and x86_64, Microsoft Windows 7 x86 and GNU Linux ARM 6 (Raspbian). 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.

Quickstart guide

The fastest and safest way to install mbpoll is to use the APT repository from piduino.org ⟨http://apt.piduino.org⟩, so you should do the following : wget -O- http://www.piduino.org/piduino-key.asc | sudo apt-key add - sudo add-apt-repository 'deb http://apt.piduino.org stretch piduino' sudo apt update sudo apt install mbpoll This repository provides mbpoll and libmodbus (version 3.1.4) packages for i386, amd64, armhf and arm64 architectures. In the above commands, the repository is a Debian Stretch distribution, but you can also choose Ubuntu Xenial by replacing stretch with xenial. It may be necessary to install the software-properties-common package for add-apt-repository. For Raspbian you have to do a little different : wget -O- http://www.piduino.org/piduino-key.asc | sudo apt-key add - echo 'deb http://raspbian.piduino.org stretch piduino' | sudo tee /etc/apt/sources.list.d/piduino.list sudo apt update sudo apt install mbpoll The Raspbian repository provides Piduino packages for armhf architecture for Stretch only.

Build from source

For example, for a debian system: • Install libmodbus ⟨https://github.com/stephane/libmodbus.git⟩ (Version >= 3.1.4) : $ sudo apt-get install build-essential libtool git-core autoconf $ git clone https://github.com/stephane/libmodbus.git $ cd libmodbus $ ./autogen.sh $ ./configure $ make $ sudo make install You can also install it with apt if the version of libmodbus is greater than or equal to 3.1.4. For example to query a debian system: $ apt-cache show libmodbus-dev • Install piduino ⟨https://github.com/epsilonrt/piduino/tree/dev⟩ only if you want to manage the RS485 with a GPIO signal: $ sudo apt-get install cmake libcppdb-dev pkg-config libsqlite3-dev sqlite3 $ git clone https://github.com/epsilonrt/piduino.git $ cd piduino $ git checkout dev $ mkdir build $ cd build $ cmake .. $ make $ sudo make install • Generate Makefile with cmake: $ sudo apt-get install cmake pkg-config $ cd mbpoll $ mkdir build $ cd build $ cmake .. • Compile and install mbpoll: $ make $ sudo make install $ sudo ldconfig If you prefer, you can in the place of direct compilation create a package and install it: $ make package $ sudo dpkg -i * .deb That's all !

Examples

The following command is used to read the input registers 1 and 2 of the slave at address 33 connected through RTU /dev/ttyUSB2 (38400 Bd) _________________________________________________________________________________________________ $ mbpoll -a 33 -b 38400 -t 3 -r 1 -c 2 /dev/ttyUSB2 mbpoll 0.1-10 - FieldTalk(tm) Modbus(R) Master Simulator Copyright (c) 2015 epsilonRT, All rights reserved.
