Checking Data Source Performance

With polling Data Sources such as Modbus, BACnet, SNMP, etc. you can easily check the performance under the Runtime status when editing a Data Source.

The Poll duration tells you how long each poll takes to complete to retrieve your data.  A poll will be discarded if the poll times take longer than your poll period.  For example if you have a Modbus Data Source polling at 1 second and your poll time takes 1.5 seconds a poll will be discarded.  It is good practice to have your poll times greater than the Poll duration.  It is also best practice to have your time out x retries to be less than your poll time.
