Max size of Assembly Input/Output data

[Ramaprasad Chakraborty]

Hi Members!

Is there any limitation on size of Input / Output Assembly data array? Upto 256 tried, but 512bytes giving problem.

Hi,

are you using a Forward Open (0x54) or Large Forward Open (0x5B) to establish the connection?

Forward Open is limited to 511 bytes payload.

Thanks Martin,

The scanner is a Schneider made NOC or communication module, no clarity on it's internal behaviour, i need to check via wireshark. I am able to access 1KB data also via EthernetIP Explorer but NOC module not supporting.

Thanks & Regards,
