System role

This section explains what the product does and where it acts in the surrounding system.

Function: Transmits Industrial Ethernet data between the host PCI bus and the connected automation network.
System position: Sits inside a PG, PC, or industrial PC between host software and Industrial Ethernet.
Upstream / inputs: Accepts host-side communication data and Industrial Ethernet frames through the documented card interfaces.
Downstream / outputs: Transmits Ethernet frames to the automation network through the ITP and RJ45 connections.
Limitations: Unknown: operating-system compatibility, installed software version, replacement fit, and live commercial availability require separate evidence.
