FANUC I/O Address Mapped I/O

Hi Andnet Deboer,

The rack number will match whatever communication you're using. The numbers are predefined (i.e., 89 = Ethernet, 100 = ProfiNet Device, etc.), and easily searched for. In your case, you're using 48 (address mapped I/O for peripheral connectors), which will apply to all your communication. The rack number will change only if you want a different communication protocol.

Slot number will not change, I think. The slot numbers are usually different for when you use more than one device on the same communication.

And the start should be whatever number you want to assign to the PLC.

For example:

If you wanted your DO[101] to turn the PLC's input 101, you map DO[101] to Rack 48, Slot 1, Start 101.

You can always assign all your peripherals consecutively. If you want DO [101 - 120] to match the PLC's DI[101-120], map DO101 - 120] to Rack 48, Slot 1, Start 101.

Hope that helps.

Welcome to the robot forum

This is an example for the DO, similar with DI

You mean

48..............1...............24 ?

You should write

48..............1.................1

meaning

first output on your crm58 is 101

second output on your crm58 is 102

When you use the 24, you are conflicting with other I/0

Show us you complete setup . What are your values on the picture that I posted ?

try again

I tried assigning DO[101-120] to rack 48 slot 1 start 101 but I got an invalid status.

First, determine what number input you want the PLC to receive your outputs, don't just go assigning them all willy nilly. Otherwise, you might end up double-mapping. Have you determined which PLC input needs to be the robot's DO[101] yet?
invalid status.

Any start that I assign that is greater than 24 for my output assignments I recieve an invalid status.

Invalid assignments can be if the Rack is incorrect, if you're trying to assign more outputs than the communciation has allocated, or if trying to allocate more outputs than allowed. Have you checked you have the right number of words / bytes in the communication with the PLC?

I also turned $IO_AUTO_CFG to true and it auto configured DO[101-120] to rack 48 slot 1 start 1.

Auto-configuration will assign the maximum number of I/O on the first spot available on the communication protocol, using the length you've entered in words / bytes. So, although it might find an available stop, it can sometimes also double map.

For example I have Start assigned to Rack 48 Slot 1 Start 23.

I noticed you mentioned you assigned Rack 48, Slot 1, Start 23. When you Auto-configured, DO[101 - 120] to Rack 48, Slot 1, Start 1 did you also double map your other IO?

Lastly, don't forget that changes to IO mapping will only be made after a controller restart.

Hope that helps.

Andnet,

I'm unsure on how your communication protocol works, since I'm more familiar with different ones.

Usually, you can find the settings for your communication protocol in: Menu > 5 I/O. Towards the end of the list the installed communication protocols are listed. There, under configuration you can change the number of input / output size.

Additionally, the PLC and robot communication size has to match. Sometimes, only the PLC can determine the communication size and the robot has it as a 'read-only'. Your PLC counterpart should be able to provide you information on the size needed.

Again, I'm unsure on what communication protocol uses Rack 48, so someone else might have a better response.

Check the electrical manual for the Mate controller. The output types have changed over the years on all controllers including the Mate controllers. You may not measure 24V at the output terminal with no load wired in place.
