Working principle
The core working principle of YOKOGAWA F3WD64-3N high-performance module controller is based on the mechanism of "multi task parallel scanning+distributed collaborative control", which achieves precise control of industrial automation processes through coordinated processing of input signals, execution of control programs, driving output actions, and interactive communication data. After the controller is powered on and initialized (including hardware self-test, program loading, parameter configuration), it enters a stable operating state, and the core workflow is divided into four stages.
The first stage is the multi-channel signal acquisition stage: the controller synchronously reads the field signals (including digital switch signals and analog process parameter signals) collected by each extended I/O module through the internal high-speed bus, and classifies and stores the signal status in the corresponding input image register. This stage adopts a parallel acquisition mechanism, which can process multiple I/O signals simultaneously. The acquisition cycle is as low as 1ms, and the input image register data remains stable during this scanning cycle until the next acquisition stage update. The second stage is the multitasking program execution stage: the controller executes multiple control tasks (such as logic control, motion control, data processing, etc.) in parallel according to the priority order of the user program. During the execution process, the controller calls the data in the input image register, and through parallel processing by a multi-core processor, updates the operation results in real-time to the output image register, while completing auxiliary operations such as data storage and logical judgment.
The third stage is the precise output driving stage: the controller synchronously transmits the operation results in the output image register to each extended output module through the high-speed bus, and the output module drives the on-site execution mechanism (such as solenoid valves, frequency converters, servo drivers, etc.) to complete one control cycle. The fourth stage is the communication interaction and fault monitoring stage: the controller interacts with the upper computer, HMI and other devices through built-in or extended communication interfaces to exchange data, upload system operating status and process parameters, and receive remote control instructions; At the same time, the built-in diagnostic module monitors the hardware status, program operation, I/O link, communication link, and power status in real time. If any abnormalities are detected (such as program runaway, I/O disconnection, communication interruption, power failure, etc.), an alarm output is immediately triggered, fault information is recorded, and redundant protection mechanisms (such as power switching, communication link switching, program self recovery) are activated to ensure the continuous operation of the system. In addition, the controller supports program backup and recovery through SD card, improving the convenience of system operation and maintenance.
