This single-channel terminal serves as a dedicated communication gateway, facilitating bilateral data transfer between the control processor and intelligent roller shutter or solar protection drives. Operating on the low-voltage SMI LoVo physical layer, the \u003cstrong\u003eBeckhoff KL6831\u003c\/strong\u003e minimizes system wiring overhead and bridges the field level directly to the controller process image using 24-byte input and output maps.
