Click the blue text to follow Servo and Motion Control 1. The Origin of CANopen, Where Did CANopen Come From? The CAN protocol was developed by the German company Bosch in 1983 for network communication in automotive transmission systems. It later became the international standard ISO11898, and currently, CANopen is drafted and reviewed by the … Read more
This article briefly introduces an example of how the Schneider M241 PLC communicates with the LXM28A servo via CANopen to achieve hardware capture functionality, including hardware wiring, software configuration, and power-on debugging. First, let’s briefly introduce the capture function of Lexium 28: •What is the capture function? The capture input can capture the motor position … 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

1、 NMT Messages 1.1、NMT Module Control Only the NMT-Master node can send NMT ModuleControl messages. All slave devices must support NMT module control services. The NMT Module Control message does not require a response. The NMT message format is as follows: NMT-Master → NMT Slave When Node-ID=0, all NMT slave devices are addressed. CS is … Read more
Based on the Industrial Internet of Things and Industry 4.0 verification, CANopen CANopen FD is very suitable for the integration of embedded networks into industrial IoT applications. The high communication flexibility is due to the powerful USDO service. USDO conveniently enables communication between any running CANopen FD devices. Moreover, the high data throughput provided by … 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
