Feature

Wondering what you’ll do now that Rockwell Automation has discontinued its

legacy 1761-NET-ENI module? ProSoft Technology’s DF1 Routing Module can

be used in a similar way.

The PLX51-DF1-ENI module provides EtherNet/IP connectivity for SLC™ 500.

CompactLogix™ and MicroLogix™ controllers, as well as many other DF1™

enabled devices

The module can be used for messaging between two controllers, uploading

and downloading PLC programs, modernizing HMI’s, or migrating legacy

Honeywell systems.

Features

 Intelligent routing to ControlLogix or CompactLogix from PLC-5. SLC,

MicroLogix controllers SCADA, DCS gateways and more

 Direct-to-tag technology simplifies data mapping, reducing configuration

time

 Secure module configuration via on module switch

 Can be used in a redundant ControlLogix system

 Built-in packet analyzer for DF1 networks to assist in trouble shooting

serial network issues

The A-CANOR/B CANopen® Router/B provides intelligent data routing between either

EtherNet/IP™, Modbus® RTU or Modbus TCP/IP® and the CANopen bus network. This

allows the user to easily integrate CANopen devices into a Rockwell® Logix platform (e.g.

ControlLogix® or CompactLogix™) or any Modbus device.

The A-CANOR/B can be configured to be either a CANopen Master or Slave allowing the

user to not only integrate CANopen devices into a Logix or Modbus system, but to also

allow the user to use Logix, Modbus, or EtherNet/IP devices in an existing CANopen

network (by using the CANopen Router B in Slave mode). In a Logix system the module

can use Direct-To-Tag technology allowing CANopen devices to exchange data with a

Logix controller without the need to write any ladder or application code in Studio 5000.

The module provides a range of statistics to simplify the diagnostic process as well as a

CANopen packet capture for remote diagnosis. A built-in webserver provides detailed

diagnostics of system configuration and operation, including the display of CANopen

operation and communication statistics, without the need for any additional software.
