Now for the fun bit, interfaces. We're going to be getting data flowing from our sensors to our users
at least we're going to take a step in that direction. In this video we'll install the
PI interface for OPC DA read only result calling it from now on the OPC interface
and all other prerequisite software we need before getting everything hooked up.
This is what we have right now. We're going to pretend on the left-hand side that we have
a distributed control system connected up to our OPC servers we'll assume that this
is all good and working it's not our job in this course to set this up it's not PI System
software we're not really going to touch it apart from reading from the OPC servers.
We'll install three things on OPC 01, we'll install the interface configuration utility
or ICU which is the tool we'll use to configure our interfaces,
then we'll install the interface and then we'll install the PI API for windows integrated security
which will allow the interface to connect to the data archive with a mapping which is what
we want. Once all this is installed we can open up the ICU and configure an interface instance.
Interface installation is fairly straightforward we'll connect to PIINT01 and then just
run the kits. Now as we run these I’m going to fast forward through a lot of this feel free to
pause the video when you need to I’ll make comments when we need to make some changes
but otherwise it's pretty much the next next next affair. So I open up the PI install kits folder on
the desktop and we'll take a look what we have the first clip we're running is the PI ICU install kit
right click on that and run as administrator. We'll accept the default unzip location that's
fine and continue so the setup tells us what's going to be installed which right now is really
everything this machine doesn't have anything on it yet at least nothing PI related that's fine
let's go. We're asked for a default server this is the name of our PI data archive it's the data
archive that any client tools installed on this machine are going to try to connect to by default
so type in PISRV01 here that's the name of our data archive in this configuration.
So we're asked for a default installation location uh just like with our other installs we're going
to keep our PI System software off the c drive and put it on its own drive just makes it simpler
to manage it later. The defaults are fine we'll just change the drive letter all right
and from now on we're just going to continue and click next next next and we're successful.
Now for the OPC interface right click and run as administrator we accept the default and we're
told what will be installed. All right next it's telling us some services that will be restarted
so seeing as though we're not doing anything with those services right now that's completely fine
we're just going to click next, but if this system was already in production
and this was an upgrade this would matter a fair bit all of these services will be restarted and
data will stop flowing through this interface while we restart which means a few minutes of
data loss which means golden rule of being an administrator your job is to prevent data loss
you failed your job. So it's not really what we want we'll be able to compensate for it by having
redundant interfaces which we'll discuss later, but we're clicking next for now and we're done.
So now for the PI API for windows integrated security accept the default location and
continue and now we're greeted with a big caution screen. We're installing the part
that will remove the ability of the interface machine to use all legacy security models and
allow us to use mappings. This is really what we want in this case this warning screen is here to
tell us that if we're upgrading and relying on an old security model then we're going to have
a bad time if we haven't thought about this. We're fine with it now this is exactly what we want for
this class but if you're upgrading in production this is definitely something to look at and read
let's click install and it looks like the next screen has jumped behind our window here this
can happen if you've got multiple windows open just click on the taskbar and it'll come back up
and click next and next on the services restarts and we're done.
Click next and finish so we can now go down to start and open the
interface configuration utility, I’ll call it the ICU from now on,
we'll use this in upcoming lessons to configure interface instances.
