[UI_SCINFO]
The [UI_SCINFO] Health Point provides scan class information. The value of this point is a
string that indicates

the number of scan classes;

the update frequency of the [UI_HEARTBEAT] Health Point; and

the scan class frequencies
An example value for the [UI_SCINFO] Health Point is:
3 | 5 | 5 | 60 | 120
The Interface updates the value of this point at startup and at each performance summary
interval.
[UI_IORATE]
The [UI_IORATE] Health Point indicates the sum of
1. the number of scan-based input values the interface collects before it performs
exception reporting; and
2. the number of event-based input values the interface collects before it performs
exception reporting; and
3. the number of values that the interface writes to output tags that have a SourceTag .
The Interface updates this point at the same frequency as the [UI_HEARTBEAT] point. The
value of this [UI_IORATE] Health Point may be zero. A stale timestamp for this point
indicates that this Interface has stopped collecting data.
[UI_MSGCOUNT]
The [UI_MSGCOUNT] Health Point tracks the number of messages that the interface has
written to the
pipc.log file since start-up. In general, a large number for this point indicates
that the interface is encountering problems. You should investigate the cause of these
problems by looking in
pipc.log .
The Interface updates the value of this point every 60 seconds. While the interface is running,
the value of this point never decreases.
[UI_POINTCOUNT]
The [UI_POINTCOUNT] Health Point counts number of Historian tags loaded by the
interface. This count includes all input, output and triggered input tags. This count does NOT
include any Interface Health tags or performance points.
The interface updates the value of this point at startup, on change and at shutdown.
[UI_OUTPUTRATE]
After performing an output to the device, this Interface writes the output value to the output
tag if the tag has a
SourceTag . The [UI_OUTPUTRATE] Health Point tracks the number of
these values. If there are no output tags for this Interface, it writes the System Digital State No
Result to this Health Point.
