the network interface on the other side of the gateway using the standard Anybus-S API.

Allocation of I/O Data
Example
I/O Size, Interface A = 30 bytes
I/O Size, Interface B = 20 bytes
Transport Provider I/O Size = 20 bytes - 10 bytes =
10 bytes
Interface A
I/O Size = 30 bytes
Interface B
I/O Size = 20 bytes
20 bytes
20 bytes
10 bytes
10 bytes
This data is available as I/O Data
on the PROFINET (Ethernet) side
This data is transported as I/O Data
through the Ethernet Transport Provider

Transport Provider example
If the Transport Provider shall handle the complete I/O image towards the other network, the I/O
size should be set to 0 (zero) on the Ethernet interface.
