製品紹介
The Allen-Bradley 1756-CN2/A is a ControlLogix ControlNet communication module designed to provide high-speed and deterministic data exchange within industrial control systems. Developed by Rockwell Automation, this module functions as a dual-capacity bridge, supporting up to 100 connections for efficient network communication.
As part / the ControlLogix platform, the 1756-CN2/A enables seamless integration between controllers, I/O modules, and other networked devices over the ControlNet network. It is widely used in applications requiring real-time data transfer, synchronization, and reliable communication across distributed systems.
The module also supports advanced communication capabilities such as CIP-based data exchange and can be integrated into safety architectures when used alongside GuardLogix or Compact GuardLogix controllers. This ensures compliance with functional safety standards up to SIL3 and PLe, making it suitable for safety-critical industrial environments.
