How-To Troubleshoot: IC693CMM321 (GE Fanuc 90-30 Training Test & Tutorial)


Welcome to PDFsupply.com A Global Supplier of
Industrial Automation. Today we’re going to be testing a GE Series
90-30 the part is an IC693CMM321. This particular device is an Ethernet Controller.
Now, I’m going to place it in the rack. I have a 5 slot rack, Power Supply, CPU, and
the Ethernet Controller. What we want to do is a full functional test.
This particular device reacts to a “ping” test.
First thing that we do obviously when we get it is to check that we have an OK LED, that
the device is actually working, and we do. So, we’ll go ahead and continue with it and
on the programmer here, we’re going to configure the device.
Communication Device, CMM321. It’s going to need an IP address in order to communicate
with it. And a Sub Net Mask. Those numbers will depend
on what you have available to you, you probably want to check with your IT people so that
it doesn’t confuse with another device. So I have chosen a number that’s not going
to conflict with anything, and we’re going to go ahead and connect up to the CPU.
Clear out any present faults. And then we’re going to download this scenario. Once the
CPU is downloaded and I’ve got these numbers and this configuration all set, and the device
is in Run Mode, I’m going to want to do a simple “ping” test.
The way you can do that is go to your Start menu, and look for your Command Prompt.
If you don’t have your Command Prompt up, you can always do a search for it and it will
come up. This is what it should look like when you
have it, looks like a DOS screen. What I want to do is type in “ping” space,
the number that you configure. You want to have an ethernet wire, ethernet
cable available. Put it into this labeled “10BASE T”
You always want to wait make sure that it connects up to the CMM321 using this “LAN”
LED. Once that’s blinking, you’ve got a connection.
You go ahead and hit “Enter” and you should get a response. There’s going to be four “ping”
four replies, and they’ll have the amount of milliseconds the replies take.
They usually range between 3 and 10 milliseconds. Another thing that you want to do, on this
particular device, is test the AAUI port. This is a Ethernet Transceiver. See the cable
goes in here. We’re going to connect up.
And underneath the device (CMM321), and I can show you more clearly later, this plugs
in. Same thing, we want to make sure that the
LED starts to blink. Right now it’s just solid. And now it’s blinking, so we’re okay.
You can just hit the UP arrow key and it will bring up this same prompt that you want, which
is “ping” that same number. Hit Enter. And again, same thing. It’s going
to “ping” it 4 times, 4 responses. As long as I get a reply every time, and there’s no
glitches, I can go ahead and do it again. No glitch.
Now, one thing I want to point out that I always do, and I’m going to mention this in
a lot of different scenarios is I always test the test equipment. So, I’ll disconnect my
cable and I’ll go ahead and try “pinging” it again.
What I’m looking for here is that I haven’t cross-referenced with another device in the
building somewhere. So, if I hit Enter, I should not get a reply.
This can take a couple minutes but you’re going to start to notice I’ve already gotten
one reply, that’s it’s timed out, there’s been no response. Two replies, and this will
carry on again for four replies, and they should all be “no”
That way I’m totally sure that I’ve only tested this device and nothing else in the building
that could be on the network. Okay and we’re going to stop the controller,
disconnect from it and show you the device itself.
This is the AAUI port that’s underneath, and this is the corresponding plug that plugs
into it. Once again, PDF Supply dot com – Global Supplier
