DeviceNet communication card

October 2003 Data Acquisition & Telemetry Infrastructure

Red Lion has produced a panel meter with built-in DeviceNet communication. This means that users can now access the display values, setpoints, and reset values stored within the PAX meter and communicate them via a DeviceNet bus. Combining this capability with the wide range of inputs and features offered by the PAX series means that a great many industrial panel meter networking applications may be addressed by such combinations.

The DeviceNet card supports polled, bit strobe, and explicit messaging. Communications set-up is easy with a DIP-switch located on the plug-in board, which allows programming of the MAC ID and baud rates up to 500 k. The PAX series offers inputs for both analog and digital applications. The analog inputs include voltage, current, process, resistance, temperature, and strain gauge, while the digital inputs cover count and rate applications. Now, with the new DeviceNet card, any of these parameters can not only be monitored at the machine, but the information can now be transmitted for higher level monitoring and process control.
