Control and information company Rockwell Automation has announced the launch of its dial-in Ethernet modem, the 9300-RADESG. The modem enables remote access to control systems and Ethernet devices over any standard telephone line.

This functionality allows service and support personnel to quickly and comprehensively react to critical situations without having to be present on site. Customers can also benefit from more rapid fault rectification and lower service costs.

The dial-in Ethernet modem is an essential part of the remote support services from Rockwell Automation. The service also incorporates the secure-copy-certified TechConnect support programme. Within the framework of this program contract customers can contact automation specialists from Rockwell Automation directly by telephone. The specialists can then solve problems by remote diagnosis and, if required, also directly access the systems. This service is always available.

With the dial-in Ethernet modem, Rockwell Automation is supplementing the Ethernet diagnostic module 9300-8EDM, which allows users to access critical network data through their Logix control platform system. Using the dial-in modem over the telephone line, they are now also able to upload and download new programs or carry out modifica- tions, update firmware, and interro- gate and gather data as well as monitor the system status.

The solution combines a 56-K dial-in modem with the functionality of a four-port switch with management functions. The integrated configuration tool can speed up and simplify the installation and help to ensure a trouble-free link to new or existing applications. Owing to its compact design the dial-in modem only takes up 5,08 cm of space on a DIN rail.

Rockwell Automation makes use of the Windows dial-up networking service for the link. This means that the modem link is not visible to communications software, such as RSLinx. The familiar Windows interface may also simplify configura- tion and use.

Other features of the model include versatility with regard to power supply, with eight volts to 48-V direct voltage, data compression that can increase throughput over the telephone line by 40%, and dial-out capability to route data packets to other networks. The modem has been specifically designed for industrial use and also offers 17 light emitting diodes that provide information on system status and network activity, virtual local area network capability and Internet group management protocol snooping to reduce network load, and extensive security functions.
