Wonderware PacWest Tech Note 80 “How to use the $PingNode Object Template in Wonderware Application Server“, written by Mark Boisvert, is available on the Wonderware PacWest website.

This tech note describes how to use a custom $PingNode object template created for Wonderware Application Server. Object based on that template provides ping status for a given machine (node). The $PingNode object template includes the Ping script that can be customized to provide additional features. By default the enabled object will ping the configured node every 10 seconds and report general status and reply time. It also can be configured to alarm if a ping timeout is incurred. This type of information should be useful for monitoring system health of network hardware and other machines that are not part of the galaxy.
