Veristand Ethercat Custom Device for 3rd Party Slaves - Setting CoE and PDO's

[BrokenArrow]

Hi,

I am currently working on a Veristand Custom Device to read the I/O of several Beckhoff Ethercat modules. So far the custom device is working and I can scan the I/O of all modules OK but now I have the problem that I can't work out how to send the configuration data to the modules. The documentation says I need to set PDO and CoE values over the Ethercat interface but I can't see any way of doing this in Labview.

Has anyone configured a similar system that could offer any advice?

The Beckhoff modules I am using are Ethercat Box EP8309 and EP3314

Thanks in advance,

Joe

there are some examples of sending pdo in labview, but I am not sure if they are built into the custom device. I would track down the examples and go from there. Also, unless these are special devices or you need configure them in a one-off way, you typically don't have to send any pdo messages to commuinicate. The driver will take care of that for you.

If its possible to set them, it will be in the section "Ethercat references and procedures" section of the help (https://www.ni.com/docs/en-US/bundle/ni-industrial-communications-ethercat/page/user-manual-welcome.... looking at the master and slave device methods. If I remember correctly there are also some super low-level examples that get installed with ethercat.
