    Abstract
  • The characteristics of real-time industrial Ethernet(RTIE) were studied. A timing analysis system was proposed consisting of probe, monitoring PC and Timing-Analyzer software. Each of the passing frames was captured by the probe which includes one field-programmable gate array(FPGA) core. The information of the original frame was extracted and encapsulated in the probe frame, which was transmitted to the monitoring PC together with the original frame. The probe frame is one specific Ethernet frame format for the timing or functional analysis of RTIE. The information contained in the probe frames was parsed and synthesized by the timing-analyzer. The graphical results were displayed according to the user-defined parameters. A verification system based on EtherCAT was presented. The implementation shows that the on-line acquiring and off-line analyzing for RTIE were carried out by the proposed timing analysis system. The graphical result is clear and useful for determining the timing characteristics of the communication links and devices.
