The server's diagnostic features provide real-time information on the communication driver's performance. All read and write operations can be viewed in the Diagnostics Viewer or tracked directly in the OPC client application with built-in Diagnostics tags. The Diagnostic Viewer also provides a real-time protocol view, which is useful when making changes to key communication parameter settings (such as baud rate, parity, or device IDs). The changes' effects are displayed in real-time. Once the correct communication and device settings are set, the data exchange with the device is visible. For more information, refer to "Communication Diagnostics" in the KEPServerEX V5 product manual.
