KL6831 | Bus Terminal, 1-channel communication interface, SMI, master, LoVo

The KL6831 master terminal connects the Bus Terminal system with the SMI bus system. SMI (Standard Motor Interface) is used for controlling and exact positioning of roller shutter and sun protection device drives. In conjunction with intelligent energy and lighting management the blades can be positioned and moved according to the sun's position. Up to 16 drives can be connected via an SMI master terminal. With the KS2000 configuration software, parameterization can be done easily via a PC, which is coupled directly to the Bus Coupler via the RS232 interface or the fieldbus. Operation is done exclusively via TwinCAT function blocks. The KL6831 is used for the connection of LoVo-SMI devices.
