Fig. 1: KL6031
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.
