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
Case Study How the Intelligent Logistics Drive System Integrates Electric Rollers (CANopen Devices) with PROFINET Controllers Application Scenario In a smart factory environment, an efficient logistics system requires an integrated and systematic approach, organically combining various adaptive logistics hardware and software technologies for different operational scenarios. CANopen is a traditional industrial automation communication protocol, commonly … Read more
1, NMT Messages CANopen devices have three states: pre-operational, operational, and stopped. By default, after startup, they automatically enter the pre-operational state, during which PDO messages cannot be sent. If PDO messages need to be sent, the device must be manually switched to operational (run) state after startup. The following message can be sent to … Read more

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
