KL6051 | Data exchange terminal with serial interface

The KL6051 serial interface terminal makes it possible to exchange data between different fieldbus systems. Full duplex data exchange is possible, independently of the higher-level fieldbus. Under the terminal’s default setting, 32 inputs and 32 outputs are transferred between the fieldbus systems. The time to exchange the data is about 5 ms for 32 bits of I/O. The exchange of data with the Bus Coupler is indicated by the run LED. The TxD and RxD LEDs indicate the state of the signal transmission.
