KL6031 - Introduction
The KL6031 serial interface allows devices with RS232 interface to be connected. It operates in conformity with the CCITT V.28/DIN 66 259-1 standards. The device connected to the KL6031 terminal communicates with the automation device via the Bus Coupler. The active communication channel operates independently of the higher-level bus system in full duplex mode at up to 115.2 kbit/s. The RS232 interface guarantees high immunity to interference through electrically isolated signals.
LEDs
LED | Color | Meaning | |
---|---|---|---|
RUN | green | This LED indicates the terminal's operating state: | |
on | normal operation | ||
off | A watchdog timer overflow has occurred. The RUN LED goes out if no process data is transmitted to the terminal from the Bus Coupler for 100 ms. | ||
TxD | green | State of the transmit signal line | |
RxD | green | State of the receive signal line |
