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
