TCP/UDP Ports used by B&R PLC

I have a B&R PLC in a machine that also have a firewall device. By using port forwarding in the firewall, we only need one public IP adress for our machine and the PLC will always have a local IP adress. But i wonder which ports are used by the PLC. Which ports needs to be allowed through the firewall?

These are the ports that I’ve found out so far:

  • Automation Studio: TCP 11169
  • Safe Designer: TCP 50000
  • Safe Designer: TCP 51000
  • FTP: TCP 21
  • Mapp Cockpit: TCP 8084
  • Mapp View: TCP 81
  • SDM: TCP 80 http
  • OPC UA server: TCP 4840

I just found out that I might need to open up TCP 50200 for the DTM as well, but I’m not sure about that one.

Does anyone know if there are any other ports that should be opened up?

You can look up available ports in the AS help.

Ethernet - Ports
dc7ec839-7dc0-4292-9f8e-540d20ecb2f7

E.g. you listed port 51000 which is for Safety Legacy. If you use mappSafety, port is now 52000 + SafeDomainID-1

Apart from that your list seems fine to me! Kind of depends on your requirements too…

Best regards,

In addition to Marcel’s reply, please note that some of the ports are customizable in the AS project. For example, OPC UA, mapp View, and the SDM can all be changed from their default ports listed above.

On some services you can use secure communication protocol (encrypted).
In this case you have additional ports numbers. For instance TCP port 443 for HTTPS or TCP port 11179 for secure ANSL.
I could not find a complete list of these port numbers.
