ALLEN-Bradley FLEX I/O now enjoys ethernet/IP connectivity, thanks to the new FLEX ethernet/IP adaptor 1794-AENT from Rockwell Automation. This adaptor utilises the same control and information protocol (CIP) as does DeviceNet and ControlNet, while combining ethernet TCP/IP and CIP configuration.
Delivering maximum communication functionality, the adaptor serves as a bridge between the I/O module and the network. The module incorporates built-in web pages offering module and network diagnostic information, module configuration, and TCP/IP configuration.
"The FLEX ethernet/IP adaptor has tremendous value for users," Rockwell product manager Gordon Senior said.
"It allows remote I/O data to be run over existing ethernet media, connection to a high-speed network capable of handling large amounts of I/O data, and easy remote monitoring of I/O and the network condition."
The two primary tasks performed by the 1794-AENT adaptor are the control of real time I/O data, and the support of messaging data for configuration and programming information. These are respectively known as 'implicit' and 'explicit' messaging.
Other features of the adaptor include: ethernet/IP communications at either 10 or 100 Mbps with interfacing via a 10 Base-T media; DIN-rail mounting; and the use of commercial, off-the-shelf communication cards, media and support tools to realise greater cost savings.
Significant time savings are also achieved, since neither network scheduling nor routing tables are required.
Part of the FLEX I/O system, the ethernet/IP adaptor offers a twisted pair (RJ-45) media, and protects existing equipment investments by being compatible with all existing FLEX I/O modules, terminal bases, power supplies, and accessories. Rockwell Automation 03 9896 0300.
