The WinCC OA Help misses TCP/UDP port information

[frankySie]

the WinCC OA help informs about alll used ports. See chapter "TCP/IP communication" mainly and others.
Missing is the information if the ports are type of TCP or UDP.
Please add this information.
E.g. it is necessary to know to configure the firewall rules.

Now we got the experience that some ports are UDP ports.

This could be a blocking point if port-forwarding is used. Typical port-forwarding solutions (puTTY, ...) are working with TCP ports only. Our test network has realized some links per port-forwarding.

Please note this udp ports.

Hello,

for the communication between WinCC OA processes TCP/IP is used. Also alive-messages are send using the TCP/IP-communication.
The UDP-communication is only used for the UDP alive messages.
For details concerning the alive mechanism please have a look at the online help: Special functions --> Connection monitoring.

Which ports are used as standard ports for the communication to the data- and event-manager is decribed at the online-help: Reference tables --> Configuration file --> General settings.
