    Hello everybody,
    I need to get the name of each device in the EtherCAT device tree and save it to a string in case it goes wrong. Is there any method? I actually can access to the ETCSlave_Diag of each device but with this seems there is no way to get the name.
    Any suggestion?

    Thank you!

    An option is to add the "application composer - device diagnosis". This will generate code including a textlist containing the names of the devices.

    See:
    https://help.codesys.com/webapp/ac_device_diagnose_overview;product=core_Application_Composer;version=3.5.17.0

    After configuring this module and generating the code, you can then get the name of all devices:

    IF DeviceDiagnosis.uiNumDDIs > 0 THEN
    FOR i := 0 TO DeviceDiagnosis.uiNumDDIs - 1 DO
        IF g_DDGInfos[i].pName <> 0 THEN
            sName := g_DDGInfos[i].pName^;
        END_IF
    END_FOR
END_IF
