The Modbus Explorer App lets you read and write data to any Modbus® device without writing MATLAB® code. With this app you can configure Modbus communication, read and write to Modbus registers, view live plots of register data, and automatically generate a MATLAB live script. The app supports communication over Modbus TCP/IP and Modbus Serial (RTU). Using interactive panels, you can set the baud rate of the communication, define the word and byte order, and set the timeout. You can add coils, input registers, and holding registers. You can save your configuration for future use, eliminating the need to set up the device each time you open MATLAB. The app automatically reads the register data and provides live plots. You can also interactively write data to registers from the app.
We'll demonstrate how to use the app to set up Modbus communication with a Click Koyo Programmable Logic Controller (PLC). The controller is programmed with two holding registers and 3 coils/switches. The holding registers are set up as counters. We'll show how to use the app to change the switch values, which will turn the counters on and off. The effect of our changes can be easily viewed in the live plots, which display the values stored in the counter registers.
2008-06-24 - Modbus Applications for Mac OS X Listed on Technical Resources Page ModBusProbe has been developed by Matthew Butch of Volitans Software and Rudy Boonstra of R Engineering Inc. To provide one of the necessary tools to use the Apple Mac OS X platform for industrial control. Description: iRidium controls Modbus as well as any other equipment (like Beckhoff or KNX), Media Servers with full 2-way communication. Your customer gets a complete solution to control all equipment, using only one app. Control Modbus and any other equipment from iPad, iPhone, Mac, Android or Windows panels. The EKI-1242EIMS Industrial Protocol gateway not only provides seamless communication between Fieldbus and Industrial Ethernet but also supports different protocol devices. Therefore, the Fieldbus gateway can integrate new and existing Modbus RTU/TCP devices to the EtherNet/IP network.
At the end of the demonstration, we'll show how to automatically generate a MATLAB live script, which can be used as reference for building test programs that require Modbus connectivity.
- Jun 26, 2019 Modbus Server provides a Modbus TCP server (and RTU slave as of V3.0) for testing Modbus clients. It simulates a Modbus device with registers. Modbus TCP Server and RTU Slave simulates Modbus Holding, Input and Output registers 0 to 65535 according to Modbus specification 1.1b3.
- Description: An intelligent and cost-effective Protocol Converter. It enables different devices to communicate with each other using Modbus RTU or Modbus-TCP protocol. An extensive library of drivers is available to support interoperability between a variety of serial device especially in the fire and process control industries.
Use the Modbus Explorer App
You can read and write to coils and registers in the Modbus Explorer app. The app supports a subset of the MATLAB Modbus functionality. You can do the following in the Modbus Explorer:
- Read coils, inputs, registers, and holding registers. This is the functionality of the Modbus
read
function. - Write to coils and holding registers. This is the functionality of the Modbus
write
function.
The app does not support the functionality of the Modbus
writeRead
function or the maskWrite
function.The Modbus Explorer offers a user interface to easily set up reads and writes and a live plot to see the values. The read table allows you to easily organize and manage reads for multiple addresses, such as different sensors on a PLC.
To launch the Modbus Explorer, do one of these:
- In the MATLAB Apps tab, under Test & Measurement, select .
- At the MATLAB command line, type
modbusExplorer
.
Modbus Tcp Ip Over Ethernet
To use the Modbus Explorer, you need to configure your device and connect over TCP/IP or Serial RTU. For information about how to configure and connect to your device, see Configure a Connection in the Modbus Explorer.
Modbus Ip Explorer For Os Xp
After you have successfully configured your device in the Configure tab, press the button to open the read and write section of the Modbus Explorer. You can then perform reads and writes. For information about doing reads, see Read Coils, Inputs, and Registers in the Modbus Explorer. For information about doing writes, see Write to Coils and Holding Registers in the Modbus Explorer.
