Introduction to Modbus

In the communication between our microcontrollers, as well as between microcontrollers and PCs, different content specifications are established. Both parties involved in the communication need to adhere to these specifications to facilitate effective communication. There are various protocols to meet different device and communication requirements, such as I2C, SPI, UART, etc. Modbus is one such serial communication protocol. It has become an industry standard in communication protocols for the industrial sector and is commonly used for connecting industrial electronic devices. Modbus plays a crucial role in facilitating communication among various devices in industrial environments, such as PLCs, sensors, and actuators.

Development Tools & Process

Modbus Arduino IDE

Arduino IDE

Arduino IDE is a powerful tool for Modbus module development. It provides an intuitive interface and support for multiple programming languages, allowing developers to easily write, compile and upload code. The IDE contains rich libraries and functions to quickly implement Modbus communication functions. In addition, it is compatible with a variety of Arduino development boards. In addtion, it also provides debugging functions.

Modbus Slave Simulator

Modbus Slave

The Modbus Slave software is primarily used for simulating Modbus slave or Modbus server devices, receiving command packets from the master station, and sending back data packets. It can simulate up to 32 slave devices/address domains. Each interface provides OLE automation support for Excel reports. Similar to the user interface of Modbus Poll, it supports functions 01, 02, 03, 04, 05, 06, 15, 16, 22, and 23, and monitors serial port data.

Modbus Poll Test and Simulate Tool

Modbus Poll

"Modbus Poll" is a PC software that simulates a Modbus protocol master, primarily used for emulating the communication process with other slave devices for testing purposes. This software encapsulates a standard Modbus protocol stack internally and provides a user-friendly graphical interface for ease of operation. Currently, the software supports functions such as detecting exception messages, viewing raw messages, and recording data.

Development Process:

Hardware selection

Choose suitable microcontrollers, communication interfaces, and other components.

Software development

Write firmware or software code to implement Modbus communication protocols.

Testing and validation

Conduct thorough testing to ensure compatibility and reliability.

Documentation and deployment

Prepare user manuals, datasheets, and application notes for customers.
