Yes, you're calling both now. Previously you had the "else-if" structured such that it wouldn't, though.
ecrt_domain_reg_pdo_entry_list doesn't require a *static* array (although that's used in the examples); you can build a temporary array if you wish, although then you're back to needing a loop. The important point though is that it captures the pointer to the actual value, which you are currently discarding in your call and simply hoping that the data appears at the offsets you expect in your process image structure. (Which, to be fair, it always should -- until you move devices around in your network or upgrade a device to a later revision with a different data model. What you have works for now, but it's brittle. But if you're happy with that caveat, then fine.)

AFAIU, `ecrt_domain_reg_pdo_entry_list` requires another explicit static array. This is a big no from my point of view, where I am struggling to keep complexity as low as possible by using conventions instead of explicit lists.
