The PLC is a controller used in industry. When selecting this device, we primarily consider whether its performance meets our needs and whether the price is appropriate. Which is more important, price or performance? Clearly, performance is paramount; if the machine cannot meet the requirements, what does the price matter? Alternatively, if the performance is … Read more
CANopen is a common industrial automation communication protocol, widely used in the industrial sector for applications such as robot control, lifting equipment transmission, and motion control devices, with extensive usage in the motor control field. Typical master station products include industrial computers, PLCs, and motion controllers, while typical slave station products include motor drivers, distributed … Read more
Introduction IIoT (Industrial Internet of Things) refers to the integration of various sensing and monitoring devices, controllers, mobile communications, intelligent analysis, and other technologies into all stages of industrial production. This significantly enhances manufacturing efficiency, improves product quality, reduces product costs and resource consumption, ultimately elevating traditional industries to a new stage of intelligence. The … Read more
Connection Method 1: Not recommended, interference leads to continuous bugs. Solution 2: Connect the passive termination resistor as shown in the figure: recommended. Connection Method 3: Connect 5V active termination resistor: Incorrect Connection Method: Error 1: The bus must be connected in a linear fashion, not in a star configuration. Error 2: Missing termination resistors. … Read more
S7-1200 Modbus RTU Communication Overview (Data information source: Siemens official website) Modbus has two serial transmission modes: ASCII and RTU. Modbus is a master-slave communication mode with a single master station. There can only be one master station on the Modbus network, which does not have an address. Each slave station must have a unique … Read more
01 Introduction MODBUS communication is widely used in actual industrial sites, commonly for data exchange and monitoring between PLCs and third-party devices such as inverters and instruments. 02 Example Application Below is a case study to fully understand the application of MODBUS. The specific control requirements are for Siemens 200SMART and Siemens V20 inverter to … Read more
Project Address https://github.com/enddo/smod Project Introduction Based on SCADA (Supervisory Control and Data Acquisition) systems, proprietary closed network protocols have developed towards open-source solutions and TCP/IP network protocols in recent years. This makes them vulnerable to the same security flaws as traditional computer networks. The Modbus/TCP protocol is one such solution that provides free public utility … Read more
