Nurchi Guseynov posted a comment on discussion General Discussion

@dadreamer, This is normal. As I understand, 505 (or 504) bytes is the maximum, so the array is preallocated. You only fill/read the data relevant to your application. This is the reason there are O_T_Length and T_O_Length properties.

@alura Just want to say thanks. I applied these settings to my test LabVIEW program. Everything works like a charm. There's one oddity though - the T_O_IOData and O_T_IOData arrays are 505 bytes long straight away, but I mostly don't care as I only use 56 and 40 bytes of them (for input and output respectively as per the driver manuals).

Hey Bisl, This was a few years ago so my memory is a bit fuzzy and I don't remember where I put that code. But I was never able to get the default code to work. What I learned though was that basically, some devices will always respond on the default UDP port regardless of claims; in my case it was a Turck FEN20. Proper Unicast UDP should allow port binding, which is why it's frustrating. So I ended up writing a connection manager that was basically a dictionary of connection objects using the built-in...

Hi, The maximum size that you can set for Forward Open are 9 bits according to the standard which is 511 bytes. For Large Forward Open are 15 bits. and it is optional to implemented. Not all the EIP devices does it. I tested with Codesys with a EIP device which I know that Large Forward Open is not implemented.
