- Cross referencing is used to indicate associations
between symbols across multiple drawings.
So, say for example, again we have our
contactor component here, K1,
most likely it's broken up
into a number of different symbols
and those symbols are spread over
a whole bunch of different pages.
It's a large project,
maybe it's spread over 50 different pages.
So finding where all of those symbols are
within our large project can be a difficult process.
But thanks to cross-referencing,
this process is greatly simplified.
So if I take a look at my K1 here,
notice just at the top here
I have something telling me "05."
So what that is, is an example of cross-referencing.
This is telling me that the parent component of this
K1 contactor is actually located on page five.
Right now, I'm on page three, which is the line diagram.
I can actually grab this component, maybe right-click on it,
and I have a option to "Go To."
This "Go To" shows me all of the other symbols
associated with this same K1 contactor.
And I can see on page five I have a couple symbols,
so I'll just jump to my page five Relay Coil,
as my Relay Coil will generally
be the parent component here.
And it will automatically jump me into page five,
the control drawing, and here I have my K1 Relay Coil.
If I just scroll over to the right a little bit here,
I can also see this little schematic diagram.
This, again, is an example of cross-referencing.
This is an even more involved cross-reference,
as it actually shows diagrams, colors and page numbers.
So how I can read this if we are new to cross-referencing,
it's telling me that this contactor component, K1,
has a number of circuits associated with it.
It looks like the first three,
the ones I'm seeing in green here,
are all normally open contacts.
My guess here normally open power contacts,
but we can take a look.
And again, the green is going back to those
circuit state colors.
So green is telling me that it's correctly associated
between the manufacturer part and the schematic symbol.
And the "04" is telling me which page number
these are located on.
So if I just jump over to page four
and look for my K1 component,
or again I can right-click "Go To,"
jump to my page four
and there is my K1 component.
So as expected it's three normally open power contacts.
And why they are coming in green,
if I actually looked into this symbol,
just double-click on it,
jump into the manufacturer part and there's my states.
That's why they are coming in green here.
So again, since I have this specific manufacturer part
tied to this K1 component, this manufacturer part
has a number of normally open power contacts,
and they're correctly associating
with my normally open power contacts symbol.
In addition to this, I also have some red states.
So again, what that's telling me is that I have
the symbols placed in my design,
but this specific part that I've purchased
doesn't have those exact electrical connection points.
So I might need some additional parts to add on to that,
or auxiliary contacts or something like this.
Just say "OK."
I'll jump back to my cross-reference here.
So that was my three normally opened contacts
that actually gives me the terminal numbers as well.
And it's also showing me everything else
that's associated with this K1.
So I know that I have a red state on page five
and a page six, looks like it's a normally closed contact,
so let's just double-check.
We can jump over to page five.
And there's my normally open contact,
again coming in red because the manufacturer part
does not have one of these contacts.
And it looks like I also have one more symbol on page six.
So again, I can right-click, "Go To," and jump to page six
and that should be a normally closed contact,
but there it is associated with K1.
So essentially, cross-referencing is just a very useful way
to help read more complex symbols and components that
are broken up across many pages.
It just tells us exactly what each component is,
where it is, what state it's in,
what page it's on, and so on.
