Maximum allowable bit transfer between Allen-Bradley PLC, and an ABB IRC5 with Ethernet/IP

Can someone point me in the direction of some reference material regarding Ethernet/IP communication setup, such as maximum input and output size setting and such.

0 -505 bytes in and 0 - 505 bytes out. Maybe 509, manual is a little vague. 3HAC050998

Depends on the adapter – what’s the part number?
