2.6 KL6041 – Basic function principles
The KL6041 serial interface terminal enables the connection either
• of devices with an RS485 interface or
• of a device with an RS422 interface (peer to peer).
Depending on the higher-level fieldbus system, data can be exchanged with the controller in full-duplex or
half-duplex mode. The size of the receive buffer is 1024 bytes, that of the transmit buffer 128 bytes. The data
transfer between terminal and controller is handled via a handshake in the status and control byte. The
factory setting of the terminal is 9600 bit, 8 data bits, 1 stop bit, no parity, full duplex mode.
LED display
The Run LED indicates the operating state of the terminal.
On – normal operation
Off – Watchdog timer overflow has occurred. If no process data is transmitted from the Bus Coupler for
100 ms, the green LED goes out.
The TxD and RxD LEDs indicate the states of the signal lines.
