Now from a System Manager's
point of view, one of the most useful little widgets here
is this, in the Data Section you will find
a plug-in for editing the archive, for looking
at Current Values, and also for looking at
stale and bad Tags. So, for Current Values, what
we are simply saying is you can go out and search for all of your
PI Tags or sub-set of your PI Tags.
There we go. I will select all of these.
And what we are going to do is show you what their Current Value is.
So here are the Current Values. If you want, you can
force this to Auto Update so you can see these change in real time.
Obviously, though, we have much better tools for
getting up-to-date data -- ProcessBook for example,
DataLink and if you want to bring it into Excel, but
as you can see, as a quick and dirty tool, it's a fine way to look
at the data, and there is an Option here to Export this
to a file. Now, take a look at Archive Editor.
With your Archive Editor you can find a PI Tag and then
edit its Value. And, if you do edit any of these Values,
there's specific flags that will go ahead and trigger
if you do edit. So, for example, let me go back -- let's
go a little bit more. How about the last eight hours worth of data
for this Tag, Sinusoid.
And, if I would like to
edit its Value, for example -- I know for a fact that was actually a hundred --
I will go ahead and put an Edit Value. I will
go ahead and type in the actual Value.
I will go ahead and Save that. And, you will notice
this little flag here called "Substituted" is
indicating to me that there's been a substitution at this
point. You can also add Annotations. So
again, using this Value, I can go ahead and add an
Annotation, and just say this was, this was
corrected by Admin.
And, if you do not
put in by whom, do not worry about that. This, any of these
changes are going to be stored in our, in our
auto-database if you have got that feature turned on. But, as you can
see, we have, indicating here that there has been an
Annotation. And, by the way, that Annotation will
show up in different clients. For example, you can show that in
ProcessBook Trend or you can bring that into Excel.
Now, the last, Is Questionable, is something that
some of our, certain of our interfaces will support, so
if, if that's something that you are interested
in, take a look at your interface documentation. See if it
supports setting things to Questionable, you know, under
certain circumstances of data collection. Now, lastly,
you can, of course, add new Values at the end. For example,
I will put in a Value of 50, and I will say
that that happened let's go with T+
7 Hours, that's today at 7 o'clock in the morning.
I will go ahead and Save it.
And that should give us a Value of 50
at 7 am. So, let's go back
minus one day, and
here's our Value of 50 recorded at 7 am.
Now, of course, this is all supposing that you have the proper
credentials using the Security
so that you have permission to write to these Tags.
Now, finally, this plug-in right here for stale and bad
points. What this is going to do is it's going to allow you to go out
and find what are considered stale or
bad Tags in your system. By stale
meaning the Values have not been changing. And you get to
set what that criteria is. So, for example, anywhere
between the last,
say four hours, the last 365 days. If they
have not, have not changed then what we will see is
those Values are going to be reported as stale Values.
