...serial monitoring devices, a technology that creates new efficiencies for SCADA systems. In a typical SCADA architecture, the SCADA system obtains monitoring data from an OPC Server that communicates to field monitoring devices. Moxa's technology enables data from serial monitoring devices in the field to be proactively sent to the OPC server and to the SCADA system, resulting in more timely data and lower bandwidth use. Moxa's active monitoring system differs from prior methods in that it uses a unique triggering device to receive data transmitted from serial monitoring devices. This serial data is analyzed to generate a device tag which is actively sent to a server that automatically generates a corresponding OPC (Object Linking and Embedding for Process Control) tag for monitoring, therefore enhancing device compatibility and the overall efficiency and bandwidth usage of monitoring systems.

This technology is currently used in a line of Moxa's cellular RTUs that have been optimized for deployment in remote locations that are difficult to connect to control centers and SCADA systems.
