Working principle

The core working principle of the YOKOGAWA F3LC21-1N multi link module is to achieve data encoding, transmission, and decoding interaction between different devices by constructing standardized communication links. As the communication hub of the system, the module first establishes a data exchange channel with the PLC main CPU module through slot type connection, receives communication instructions and configuration parameters from the main station, and specifies key parameters such as communication mode (remote I/O station/remote equipment station/local station), transmission rate, and station address.

In the data transmission stage, the module processes different types of data according to the preset communication mode: in remote I/O station mode, only the on/off status data (remote input RX, remote output RY) is collected and forwarded; In remote device station mode, in addition to on/off data, digital data (remote registers) are also packaged and transmitted; In the N: N mode of the local station, bidirectional data exchange between multiple PC CPUs is achieved, establishing a synchronous transmission link for bit data and word data. The module sends data frames at a set rate (up to 10Mbps) through a high-speed communication interface, while receiving real-time feedback data from the slave station, completing link scanning and data verification to ensure the accuracy of data transmission.

In addition, the built-in protection mechanism of the module will monitor the circuit status in real time. When abnormal situations such as short circuit, overcurrent, overvoltage, etc. are detected, the protection action will be immediately triggered to cut off the faulty link or issue an alarm signal, avoiding the expansion of the fault and ensuring the stable operation of the entire control system.
