ControlNet Router
A-CNR
The A-CNR ControlNet Router provides an efficient method of bridging between ControlNet and Ethernet networks. The module provides intelligent routing between EtherNet/IP or Modbus TCP/IP and a ControlNet network. The module can be configured as a ControlNet Target or an Originator. As a ControlNet target, a Logix controller can own the ControlNet router using a scheduled connection. As a ControlNet originator, the module can be configured to own ControlNet I/O or exchange data with up to 10 ControlNet devices.
The module can also be configured as a PCCC Client (allows the module to emulate a PLC5 or SLC5 providing legacy interface to PanelViews), EtherNet/IP target or originator, and as Modbus TCP/IP client or server.
As an EtherNet/IP target, a Logix controller can own the router using a Class 1 connection. As an EtherNet/IP originator, the router supports class 1 connection or explicit messaging.
As a Modbus TCP/IP client, the router can map ControlNet data to Modbus registers for exchange with Modbus TCP/IP servers. As a Modbus TCP/IP server, the router can exchange the ControlNet data with Modbus TCP/IP clients.
The I/O data can be accessed via Ethernet using either the PCCC or EtherNet/IP™ or Modbus TCP/IP protocols. The support for PCCC protocol allows the module to emulate user-defined PLC5-type data files data simplifying the migration to Ethernet-only PanelViews. The module also provides a range of statistics on Ethernet and ControlNet to assist with fault finding.
A built-in webserver provides detailed diagnostics of system configuration and operation, including the display of ControlNet operation and communication statistics, without the need for any additional software.

Features and Benefits
- Own ControlNet I/O enabling the migration from legacy Logix systems/controllers to newer EtherNet/IP Logix platforms, without replacing the existing ControlNet I/O.
- Can be configured as a ControlNet Target or Originator.
- Can operate as ControlNet Keeper.
- Supports Promiscuous Capture mode allowing the ControlNet Router to capture all traffic on the ControlNet network.
- Can be configured as an EtherNet/IP Target or Originator.
- Can be configured as a Modbus TCP/IP Client to exchange ControlNet data with Modbus TCP/IP servers.
- Can be configured as Modbus TCP/IP Server to exchange ControlNet data with Modbus TCP/IP clients.
- Connect Ethernet-only PanelViews to Logix via ControlNet.
- Supports Scheduled & Unscheduled ControlNet for PanelViews.
- Program Logix controllers via ControlNet.
- Supports Redundant ControlNet and Ethernet.
- Advanced Diagnostics, including packet capture and webserver.
Configuration
The Slate Configuration Utility software is used for configuration and troubleshooting of the module. The stand-alone configuration utility allows users to define the setup and configuration of the ControlNet router, connections with controllers and devices.
The configuration utility can be downloaded from the "Downloads" section.
