Active monitoring system for serial monitoring device and method thereof
An active monitoring system for serial monitoring devices and the method thereof are provided. By receiving serial data from a serial monitoring device on a triggering device and analyzing the serial data to generate a device tag, the mechanism transmits the packed device tag actively to a server through a network. The server automatically generates a tag compliant with the Object Linking and Embedding for Process Control (OPC) according to the device tag for monitoring. The mechanism improves the compatibility and efficiency of monitoring and bandwidth usage.
