Today we're going to be talking about a new adapter that we have.
This is our M12 X code adapter.
I've been told that the X in X code stands for 10 or 10 gig.
We're seeing a transition in factory environments where rather than using bus
technologies to communicate with different devices,
io devices, a HMI devices that are out on the factory floor,
there is an interest to run ethernet closer to the edge and our factory floor.
That's great. Ethernet is a understood protocol.
It allows us to choose some more generic switches and routers,
but the factory environment is still very difficult and so if we look at
this M12 this is again the X code,
so it's four pairs capable of supporting 10 gigabits Ethernet.
We have concerns beyond the standard signal to noise ratio that we usually look
at with Ethernet with attenuation, and NEXT and return loss.
We start to worry about M.I.C.E.
M.I.C.E., yes. Is there going to be mechanical stress on our cable?
Is there the possibility of ingress oil or something and the 'E' mice has to do with
the electronic environment. There are three levels,
E1, E2, E3, representing a standard office would be an E1 environment.
E2 would have more interference and an E3 environment,
perhaps in a industrial environment where you may have arc welding machines or
large motors sources of electromagnetic interference.
So I want to test this connector.
It helps to have this M12 X coded adaptor to put it on,
but now what tests limit am I going to use for this? Well,
from the building world,
we're used to talking about the telecommunications industry association,
the TIA 568 standard,
but the TIA 568 standard is for buildings,
not industrial environments. TIA does has of a standard,
the 1005 standard is designed to be used in industrial environments.
What I've found is it's not as well known as possible.
So let me explain it to you a little bit.
When we go in here and choose to do a new test,
we're going to default to our standard category 6A unshielded cable and our
standard category 6A permanent link. Industrial people may be saying permanent
link? Not familiar with this term. Select the cable type.
Go down here and select more.
Go here and select generic and I can select a category 7
or a category 7A S/FTP suggests that there's both an individual and an overall shield on that
and an overall shield on that cable.
Now, the shield test will determine pass or fail.
We'll always look to see if there's continuity in the shield and to make sure
that the shield follows the path of the cable. If the shield tests enabled,
we'll check to make sure there's continuity. Now the test limit,
I'm going to choose more down here in the bottom corner and well let's start
with the TIA limits and we'll take a look at category 6A.
Here are our 568 limits with channel and permanent link.
Our MPTL limits. Please see our video on MPTL, MPTL +POE.
And then we start to get down into these 1005 limits.
You'll see there's a permanent link and a channel test.
Then we have the E1, E2, and E3.
The E1, E2, and the E3 are for those environments
that have a M.I.C.E. rating of E1, E2, or E3.
Let's select the basic E1 limit to start with.
and run a test here.
I'll use selected and push test to start.
Now what going to add to the test,
the basic test outside of well wire map and length,
we measure how much signal is getting through actually how much signal we lose
and we measure noise parameters.
Noise parameters can be NEXT from one pair to another pair or return loss,
which is a measure of reflected signal on the cable.
Now by choosing E1, E2, or E3, we're going to add another parameter
that is this TCL transverse conversion loss.
In simple terms,
Transverse conversion loss is a measurement of whether or not your cable is balanced
and by balanced, is each leg of the pair electrically similar.
If each leg of the pair is going to treat the signal in the same way,
then we're able to eliminate external interference.
So the TCL test is something that will tell us the limits for the TCL test
are in the 1005 and as we get to noisier and noisier environments,
as we move from an E1 to an E2, or E3 environment
an E3 environment that is more electronically noisy,
we want to make sure that the cable has better balance.
That means that it's more immune to external noise.
Now we are using a shielded cable,
so the shielded cable should eliminate any of that external noise from getting in
and we'll find in the ISO world an open discussion about whether or not the,
it's not much of a discussion in the ISO world. If you have a shield,
you're not required to run these TCL tests. All right,
so we've seen in the 1005 tests that we have some tests that include the TCL values
and some that do not. As we get into a tougher environment,
we may be interested in using the more stringent tests,
the E2 or the E3 tests. Please check with your consultant.
What does your contract say? What are you required to test.
