Interface settings for using an Ethernet port for Fieldbus communication in zenon Logic (e.g. ProfiNET)

When using a local Ethernet interface for Fieldbus communication in zenon Logic, you have to ensure that VLAN and/or priority settings (cf. IEEE802.1Q) are deactivated in the network adapter configuration.

Therefore, go to the Network controller settings in Administrator mode and open the Ethernet adapter configuration by clicking on the "Configuration" button:

Go to the "Enhanced" page in the upcoming dialog. Depending on the network adapter, different options may appear.
Find a setting dealing with VLAN and/or priority and make sure to deactivate those. Otherwise, you might not be able to communicate with field devices!


If required, you can also set other options here such as manually force a specific MAC address or fix the network speed to e.g. 100 MBit.

Additionally, you should deactivate any unused protocols in the network configuration to avoid unnecessary network traffic on the fieldbus network.
Therefore, go back to the Network controller settings and only activate the following protocols:
  1. Internet Protocol Version 4 (TCP/IPv4) [required for Fieldbusses based on IP]
  2. COPA-DATA Multiple Network Protocol Driver [required for Fieldbusses that operate directly on MAC-Layer / Layer 2, e.g. ProfiNET]
  3. Npcap Packet Driver (NPCAP) [required to record Wireshark traces on this network interface]
