PR6423002-001-CN In a control system, although there are some process quantities that have high real-time requirements, but at the same time there are more process quantities that do not have special requirements for real-time, if the same refresh speed is used to deal with them is actually a waste of system resources, and the cyclic scanning operation mechanism also results in the processing cycle of the system mainly depends on the size of the application programme, such as If the application is complex and large, the scanning cycle is inevitably longer, which is undoubtedly contrary to the high real-time requirements of the I/O channels.

The PR6423002-001-CN is now widely used in frequency and phase measurements as well as PWM (pulse width modulation) and other time processing applications that require extremely high accuracy. In addition, the main board of the CPU integrates a variety of communication interfaces, and the PCC is also a highly open product configured with a variety of communication modules. all the digital inputs of the PCC have been isolated by opto-electrical coupling, and the analogue inputs have been processed by RC filtering, so it has a very good ability to resist electromagnetic interference.
