Overview

The Modbus Router provides intelligent data routing between EtherNet/IP and Modbus (serial Modbus-RTU or Ethernet Modbus-TCP). NOTE: The Modbus Router can communicate on serial RS485 or RS232. The Modbus Router allows the user to integrate Modbus devices into a Rockwell Logix platform (e.g. ControlLogix or CompactLogix) with minimal effort. The Connection to Logix can be over standard Ethernet or USB.

The router can be used to communicated with MicroLogix and SLCs.

The Modbus Router is able to transfer data from various Modbus devices to a maximum of three Logix controllers. The module operates in one of three modes, simplifying the configuration for all applications.

Mode	Description	Message Initiator
Reactive Tag	The Modbus Router will convert Modbus messages to Logix controller tag reads or tag writes. (Modbus Slave)	Remote Device
Scheduled Tag	The Modbus Router transfers data between a Modbus device and a number of Logix tags, using a preconfigured scheduled. (Modbus Master) No Logix or remote device configuration is required.	Modbus Router
Unscheduled	The Modbus Router transfers messages received from a Logix Message Instruction. (Modbus Master)	Logix (Msg)

The Modbus Router is configured using the Aparian Slate application. Slate offers various configuration methods, including a controller tag browser.

The module can operate in both a Logix “owned” and standalone mode. With a Logix connection, the input and output assemblies will provide additional diagnostics information which will be available in the Logix controller environment.

The Modbus Router allows the user to integrate Modbus devices into a Logix system with minimal effort. No copying or mapping of data in the Logix controller is required as the Modbus Router writes directly into Logix tags. The Modbus Router can access a Logix controller by either using EtherNet/IP or CIP USB.

The module also provides a range of statistics and traffic analyser to help fault find anyproblems.

The Modbus Router supports Modbus on two ports which can be configured from the Slate environment: Modbus-RTU (Serial) or Modbus-TCP (Ethernet).

The Modbus Router uses isolated RS232 or isolated RS485 for Modbus serial communication providing better noise immunity. The RS232 and RS485 ports use a terminal block for convenient installation.

A built-in webserver provides detailed diagnostics of system configuration and operation, including the display of Modbus operation and communication statistics, without the need for any additional software.
