Finding the EtherCAT Slave XML File On My PC

  • NI-Industrial Communications for EtherCAT

Issue Details

I'm looking for the EtherCAT configuration file for my slave device. Where is this XML file located on my PC?


The XML file can be found in the following locations:

LabVIEW 2013 SP1 and later:

<Program Files>\National Instruments\LabVIEW XXXX\resource\Framework\Providers\indcomecat\DD where XXXX is the LabVIEW version you're using.

LabVIEW 2013 and earlier:

<Program Files>\National Instruments\Shared\IndComECAT\DD 

Additional Information

The EtherCAT XML files contain configuration data for EtherCAT communication. In LabVIEW 2013 SP1 the XML file moved so that it can be version-dependent (i.e., have different XML files for different versions). 

If you are using an NI EtherCAT Slave and the file is not present in the folder, the NI-Industrial Communications for EtherCAT driver may be corrupted. Reinstall the driver to resolve this.
