15. QUERY SERVICES

Query services are useful for viewing every parameter in every YVP. It is accessible by
several methods: from the Device Query icon in the tool bar, from the IVI, or PID dialogs
and by right-clicking a selected device in the device tree. As many as 30 Query dialogs can
be open simultaneously to examine parameters in the selected function blocks. Click Read
to update. They are not refreshed. A query will remain active even when the device to
which it is directed is no longer the selected device.

The General tab provides a selection from commonly used parameters. Use the scroll bar
to select a parameter, then click Read.
