Can I use the ERTEC ASIC as standard Ethernet controller?
YES, The ERTEC 200/400 can be used as standard Ethernet controller with up to 4 ports.

In Wireshark I cannot see the VLAN tag in the PROFINET messages. What is the reason for this?
Probably the Ethernet card and/or driver of your PC filters away the VLAN tag. You have to enable it with the properties in Windows or add some lines in the Registry. You can request a document from us that describes what to add to the Registry.

Do I still require a mirror port on a switch if I monitor a PROFINET network with a ProfiTap?
NO, the ProfiTap has to placed between the PLC (PNIO controller) and the 1st switch. You save a mirror port and there is no risk that the Laptop/PC sends data on your network, but you have to "break" the cable to insert the ProfiTap and that automatically means a temporarily disturbance. I recommend to insert the ProfiTap during the cabling phase and leave it permanently in the loop.
