Specific OPC server knowledge enables OPC Expert to provide custom error messages based on the particular OPC server in question. OPC Expert contains specific knowledge on many OPC servers from companies such as Rockwell, Siemens, Schneider, Kepware, Emerson, Honeywell, Matrikon, and others. When troubleshooting connections with any of these servers, OPC Expert uses existing knowledge to tailor its error messages for the specific situation and warn users about OPC server problems such as demonstration timeouts, licensing, user limitations, etc.
OPC Snapshot records all computer settings affecting OPC communication to a file. This saves users from having to save a multitude of screenshots, and traverse through complicated documentation for instructions on how to find specific settings.

OPC Expert can also compare snapshots to determine the difference between them.
