ROCKWELL Automation has introduced the Allen-Bradley EtherNet/IP-to-DeviceNet linking device (1788-EN2DN), suitable for economical, efficient and seamless data sharing between networks and controllers.
The linking device provides an alternative to PC-based gateways and racks of communication cards for connecting EtherNet/IP and DeviceNet, cutting system costs and increasing data-transfer rates.
The linking device acts as a bridge for explicit (information) messages between EtherNet/IP and DeviceNet, allowing data collection and configuration to take place from any PC with an Ethernet interface.
Data also can be collected from any device on DeviceNet for display, trending and monitoring, using an EtherNet/IP-ready industrial operator interface and software, such as the Allen-Bradley PanelView and Rockwell Software RSView.
For control, users can scan DeviceNet I/O remotely over EtherNet/IP and then send information to any controller on the network. The scanner interface is compatible with any Allen-Bradley Logix controller, as well as any controller that supports EtherNet/IP.
The linking device contains a simple Web interface, allowing the user to obtain DeviceNet diagnostics remotely and configure Ethernet parameters such as the IP address.
One side of the linking device is a DeviceNet scanner with the capacity to handle 496 bytes input words and 492 bytes output words of data from DeviceNet-compliant devices such as sensors, drives and I/O blocks. The other side is an EtherNet/IP adapter.
The 1788-EN2DN adds to the Allen-Bradley family of linking devices, which includes the 1788-CN2DN (ControlNet to DeviceNet), the 1788-CN2FF (ControlNet to Foundation Fieldbus) and the 1757-FFLD (EtherNet/IP to Foundation Fieldbus).
