Basic Function Principles

The KL6051 serial interface terminal makes it possible to exchange data between different fieldbus systems. Data can be exchanged in full duplex mode independently of the higher-level fieldbus system. In the default setting of KL6051, 32 inputs and 32 outputs are transferred between the fieldbus systems. In addition, the optionally displayable status byte contains information about the quality and status of the data transmission. The terminal is supplied with an RCV timeout of 200 ms. This means that the inputs of the higher-level controller are set to zero if the terminal does not receive any valid data via the serial interface from the second device for more than 200 ms. Up to 40 bits of inputs and outputs plus control/status bytes can be mapped through reconfiguration.
