Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
Direct connection of SSI encoders to the K-bus system is facilitated by the BECKHOFF KS5051 1-channel SSI encoder interface terminal. This module provides a dedicated interface for absolute positioning systems, receiving differential RS422 signals and supplying them to the higher-level controller via the process image. The KS5051 features a pluggable wiring level, making it highly serviceable for rapid module replacement without disconnecting field wiring.
Operating as a bidirectional unit, this bus terminal supports data transmission rates up to 1 MHz and accommodates variable serial input widths of up to 24 bits. It integrates 500 V electrical isolation between the internal K-bus and the field potential to protect sensitive processing electronics from electrical surges in harsh environments.
