KS6201 | BECKHOFF | Bornier de bus

Description

Operating as a dedicated master interface on the local K-bus network, the Beckhoff KS6201 Bus Terminal enables direct connection of AS-Interface (AS-i) networks to higher-level fieldbus control architectures. This terminal incorporates a pluggable wiring design, allowing the electronic module to be easily extracted from the terminal housing without disconnecting the field wiring, thereby minimizing machine downtime during maintenance cycles. The unit supports the integration of digital and analog field devices, offering high-performance diagnostics and flexible process image structures to accommodate complex sensor-actuator topologies.

Key Features

• AS-Interface Master Functionality: Complies fully with AS-Interface specification versions 2.0 and 2.1.
• Flexible Slave Capacity: Supports up to 31 standard slaves (V2.0) or up to 62 extended-addressing slaves (V2.1).
• Pluggable Wiring Interface: Fast, tool-free installation and replacement via secure spring force connection technology.
• Selectable Process Image: Dynamic mapping options of 12, 22, or 38 bytes (including 6 bytes parameter interface) to optimize bandwidth utilization.
• Integrated Diagnostics: Continuous monitoring of power supply status, active slave communication health, and parameterization status.

Industrial Applications

• Material Handling & Logistics: Efficient control of distributed sensors and actuators along long-distance conveyor runs.
• Automated Packaging Machinery: Seamless integration of pneumatic valves, proximity switches, and safety interlocks.
• Specialized OEM Machinery: Decentralized networking within compact control cabinets using space-saving 12 mm form factor modules.

Alternative Models & Compatibility

The KS6201 is hardware-identical to the standard KL6201 in its electrical and software features, but features a modular, pluggable wiring layer. In systems where quick-swap capability is mandated by plant standards, the KS6201 can directly replace a KL6201 without changes to the TwinCAT System Manager software configuration, provided the physical base layout matches.

Application Pitfalls & Engineering Notes

This module features no integrated power contacts. Under no circumstances should you attempt to bridge standard 24V DC field bus power into the AS-i communication terminals. The AS-i network requires a specialized 30V DC power supply with integrated data decoupling networks. Connecting standard 24V DC control power directly to the AS-i bus lines will instantly short-circuit the high-frequency communications and may cause hardware degradation.

Commissioning & Wiring Tips

When configuring the terminal using the KS2000 configuration software or during initial PLC hardware scan, ensure the physical process image bit width (12, 22, or 38 bytes) configured in the PLC master matches the dynamic setting of the terminal block. A mismatch in process image allocation will result in a K-bus transmission error, halting communication across all downstream modules on the DIN rail stack.
