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?
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.
