Data acquisition for Rockwell Software's RSBizWare
The Historian module extends the reporting, analysis and management capabilities of the RSBizWare foundation by providing a powerful set of tools to analyse a wide variety of time-series data.
The device, which occupies only 2in of DIN rail space, offers an analogue phone line input and four 10BaseT Ethernet ports for RJ45 connectors.
Modem connection speed is 56Kbit/s, and data compression increases throughput by 40%.
Users can choose to configure the 9300-Rades locally via an Ethernet port or remotely over a dial-up connection.
Once the system is configured, users can access their sites using Windows' built-in dial-up networking.
By configuring an Ethernet driver in Rockwell Automation's RSLinx communication server, users can then use RSWho, an RSLinx utility, to scan and identify all devices recognised by the network.
Security is vital in remote applications, and Rockwell Automation has implemented security at several levels.
Users can set up 10 dial-in accounts, and built-in caller ID will accept calls only from pre-programmed numbers.
The modem will accept a password and then call back to a preprogrammed number.
Finally, the 9300-Rades incorporates the Challenge Handshake Authentication Protocol.
The modem is supplied with an AC adapter, a telephone cable and a 6ft UTP patch cable.
All four Ethernet ports detect and correct crossover cables and the 9300-Rades automatically selects 10 or 100Mbit/s speed.
The 9300-Rades remote access modem improves the ability of users or maintenance engineers to respond quickly to critical situations without having to be on site.
Whether at home, office or another site, all they need to gain full access to a network is a PC and any standard phone line.
