【英文介绍】
The 1756-CN2R is a ControlLogix communication module that is an important part of the Logix controller platform. It is primarily used to establish connections in redundant control network topologies because it has two BNC
control network ports. This module uses 1786-RG6 quad-shielded RG6 coaxial cable to connect to the network and supports transfer speeds of up to 5 Mbps. In addition, the 1756-CN2R is equipped with a USB port that supports
a full-speed transfer rate of 12 Mbps.
The 1756-CN2R communication module has a wide range of applications, can cover each 1000m control network segment, and can be easily extended by using Repeaters as signal enhancers for control network segments above
1000m. It also supports communication with human machine interface (HMI) devices and supervisory control and Data acquisition (SCADA) systems.
The ControlLogix system is a flexible control system platform that supports multiple controllers connected to a network in a single chassis for redundancy and enhanced system availability. The 1756-CN2R communication module
plays a key role in such systems, supporting redundant control networks to ensure system stability and reliability.
The ControlLogix controller has large capacity storage to support process-intensive applications and fast motion control applications. It supports an unlimited mix of processors and communication modules, as well as I/O, and can
use the network to distribute control to additional racks as the system grows.
Overall, the 1756-CN2R communication module is a high-performance, highly reliable communication solution for a variety of industrial automation applications.
