This video will demonstrate how to use the WAGO 750 Series I/O with an Ethernet/IP Master.
And we're just going to connect a patch cable between the WAGO coupler and the CompactLogix
L32E processor. Alright, we're just going to wire up a couple
of field devices for this demonstration. We've got an indicator lamp, a proximity switch
and a flow meter. And we've got a two channel digital output,
going to wire straight to the I/O module. One of the big advantages of the I/O system
is the, uh, commoning connections right on the I/O system, so you don't have to, have
um, your standard, uh, 24 volts and common, uh, terminal blocks. uh, also for the analogs
and also, you're three wire and four wire sensors, you have a convenient place to land
those wires right on the I/O system. So, here I'm wiring up the proximity sensor,
on the digital input. and now we're going to wire in the flow meter,
its a zero to ten volt. We also have these communing modules, that
provide a 24V and common potential, again to simplify the installation.
and need a little jumper here to tie in the reference potential to our 24V common plane.
Now we're ready to set the IP address of the 881.
and here we're going to just set the last octet to a three. Which would be 192.168.1.3
for the default. and I'm going to power up the node.
So, now we're going to go and change the IP address to something different, using the
web browser. I'm just going to navigate to the 192.168.1.3 that we just used, go to the
TCP/IP page, log in with admin/wago, and then I'm going to change the IP address to 192.168.4.3,
and you could change this to anything you'd like at this point.
Then I want to go down to the ports tab and enable the Ethernet/IP and disable the Modbus
TCP. At this point we can actually program our
Ethernet/IP master. We're going to first go into the addressing
tool, and uh, calculate what the addresses are based on the I/O on this node.
I've got an 880, and digital in, digital out and analog in, analog out.
I'm just going to select the modules that I have, uh,
on this node. You can also calculate these manually. Basically
it (the PLC) just maps the analog values first, and then maps the digitals
on the first available (memory) word after that.
Sometimes its nice to, on a big node, to have it, a tool to do that.
So these are you're Ethernet/IP assembly instances, so just make note of that.
Then we're going to go in and create a new project for our AB controller.
We're going to add a generic Ethernet/IP module, going to change the comm format to SINT, and
then here we're going to enter in the instance, assembly instances for our node
with the right size (bytes). Just going to give it a name, set the IP address
to what we used before. and we're going to go online, and make sure
that we are making communication. So you can see we're online, the "I/O" is
"OK". and you can see the input changing.
Now, we're just going to add a bit of logic to our program.
I'm going to go in to the program tags and add a few aliases, um, to reference our I/O
that we have here. Going to make one for our proximity switch
input, and add another one here for our lamp output,
and then one for our flow meter. So, then in our main routine, I;m going to,
uh, add some ladder here. If we sense the proximity switch, then were
going to drive the output (lamp). and I'll add a rung here to just do a compare
for our flow meter, uh, just against some arbitrary number, 10, so we can, uh 20, sorry.
We'll toggle an output. We'll create a new tag here called flow alarm. We'll tag that
to the second output. Alright, and well go ahead and save this and
download it. Now we're ready to test the, uh, remote I/O.
So, here I've got the proximity sensor thats driving the output whenever it senses it.
This really demonstrates how fast the communication is between the ethernet/IP master and the
WAGO remote I/O. Every time that sensor is tripped, it uh the
logic is actually being done in the CompactLogix, and you can see it the lamp output.
And here I'm just going to spin the flow meter and you'll see that second output come on.
and that concludes this video, hope you've enjoyed it, thanks.
