Displays the current value of the proxy point including facets and status.
The value depends on the type of control point. Facets define how the value displays, including the value’s number of decimal places, engineering units, or text descriptors for Boolean/enum states. You can edit point facets to poll for additional properties, such as the native statusFlags and/or priorityArray level. Status reports the current health and validity of the value. Status is specified by a combination of status flags, such as fault, overridden, alarm, and so on. If no status flag is set, status is considered normal and reports {ok}. |
Action
Ping sends a message to a URL. The message provokes a response, which indicates the current state of the object.
