Events are important time periods that affect your asset operation: downtime, equipment
shutdown, any deviation from ordinary activity.
In the PI System, events are known as Event Frames.
If you'd like to learn more about Event Frames, check out the additional resources in the description
below.
In this video I’ll be focusing on how to acknowledge and comment on an event in PI Vision.
Hi, this is Andreas from OSIsoft.
Let's say we are a member of a team responsible for the operation of a set of mixing tanks; we need
to keep track of any process excursions; data values that might indicate we have issues.
So, let's go to the Events pane and look at the events that occurred in the past few hours
for this mixing tank.
Great, our events are colour coded and if we hover over the colour, we see this represents
event severity.
So, we have information, a warning and a critical event that occurred in the past few hours.
In order for these colour labels to show up in PI Vision, Event Frame severity needs
to have been set in the PI Asset Framework.
There’s a link to a video showing how to do this in the description below.
Notice that as I click on these events, the values change in the attributes pane below,
providing us with critical information such as event duration or reason code.
To acknowledge or comment on an event we need to access the event details.
One way to do this is to right-click and select event details.
This will open the event details in the same browser tab.
Another way is to create an Events Table.
We can acknowledge an Event straight from here by clicking on the Acknowledge button.
This would let our team know that we are aware of or looking into this event.
I can also double-click on an event-row to access the details.
This will open the event details in a new browser tab.
Here we have our trend at the top showing us the time series attributes of the Event
Frame and the related asset attributes table at the bottom.
But we also have a table called trigger attributes in the middle here which focuses on the attribute
values that triggered the Event Frame.
So now I want all my other teammates to know that I have seen this event and that
I'm taking ownership of it.
In order to do that, I'll click on the acknowledge button at the top here so when any of my teammates
view this event in PI Vision, they'll see that I’m already aware of it.
For the acknowledge button to be available, the Event Frame needs to have been configured
to accept acknowledgements in the PI Asset Framework.
So, let’s say I conducted an analysis on the event, and I’d like now to share my
findings with the rest of the team.
To do that we'll add a comment.
To add an attachment to our comment, all we need to do is click on the attachment button here.
By default, the maximum size of attachments is 7 MB and only specific types of files can
be attached, but your PI AF administrator can customize these limitations.
When I'm ready to add my attachment all I need to do is click on the add button here.
Now when any of my teammates come to see this event, they'll see both my acknowledgement
and my comment, and they'll be able to see exactly what happened.
One last thing to note is that in order to acknowledge or comment on an event, you need
to have the proper permissions in the PI Asset Framework on that Event Frame.
For more information on how to set this up, please refer to the information on Live Library
and specifically “Set permissions to allow users to acknowledge and annotate events”.
So, PI Vision offers a great way to view and share data with your colleagues.
