System role

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

Function: Transmits Industrial Ethernet data through the CP 1623 two-port RJ45 switch.
System position: Sits in a PC or industrial PC between the host automation application and the Industrial Ethernet network.
Upstream / inputs: Accepts host communication data and network frames through the PCI Express and RJ45 interfaces.
Downstream / outputs: Transmits switched Ethernet traffic to connected automation-network devices.
Limitations: Unknown: host software release, slot and power compatibility, network topology fit, and current commercial availability require separate evidence.
