EtherCAT: "Found an unsupported module on the slave device"?

[JKSH]

Hello,

I have a CompactRIO system which uses EtherCAT slave chasses (cRIO-9081 + cRIO-9144) When I tried deploying my settings, I got this message:

Found an unsupported module on the slave device at the address 0: slot 32445

What does this mean? (I have several slaves daisy chained, but I sure don't have that many slots!) The chassis that was flagged with a red exclamation mark contains these modules:

• NI9201
• NI9203
• NI9265
• NI9421
• NI9481

Is one of them unsupported over EtherCAT? If so, is there a list of supported/unsupported modules somewhere?

Thanks!

Hey there,

I think you may find this KnowledgeBase, http://digital.ni.com/public.nsf/allkb/CA3A1D2166A4591386257514007A0F9C?OpenDocument , useful. It would be best to check what version of DAQmx you're using and then check the associated readme for compatibility or check this DeveloperZone, http://www.ni.com/white-paper/10462/en. I hope this helps.

Hi Miles,

Thanks for the links. I'm not using CompactDAQ and all 5 of my modules appear in the supported modules list, but the KB suggested that improper seating could cause this message. So, I removed + re-inserted all modules, then deleted the chassis from the project and re-added it (using "Discover an existing target(s) or device(s)"). That seemed to do the trick.

Hello,

I am having this same problem. The error code given is...

"Found an unsupported module on the slave device at the address 0: slot 2"

On Slot 2 I have a 9203 which shouldn't have any problems based on the C-series compatibility chart and the documents posted above.

I have switched this module out with a known good 9203 and I get the same error... When I remove the module from the project the error just moves on to the next module in slot 3, a 9425, also supported.

My software is up to date. and I installed the Ethercat software on my CRIO.

Has anybody run into this problem before? I must be missing some config stuff.

Any help would be appreciated.

Thanks,

Eric

Ok,

For whatever reason, once I removed the 9144 chassis from the project and re-built the modules, it works. I guess it doesnt like you configuring the modules and channels before you have the hardware connected. I was hoping to not have to rebuild it since I lost all my channel names I had already configured.
