Which ports are used by WinCC flexible?

Configuration Notes:The Ethernet ports are assigned by the IANA (Internet Assigned Numbers Authority). When using a firewall you must enable all the ports specified in the table. All the services listed are handled via the TCP/IP protocol, except archiving via UDP.
The following ports are used in WinCC flexible Runtime:
 

	Service			Port
Web server	Access to internal HTML pages (HTTP)			80
	Access to internal HTML pages (HTTPS)			443 (SSL)
Sm@rtServer	Connection with the Sm@rtServer (access to the Sm@rtServer for downloading the Java applets with the Internet Explorer)			5800
	Connection with the Sm@rtServer (access to the Sm@rtServer with Internet Explorer for remote monitoring and operation)			5900
OPC
	OPC via DCOM	Server	Connection setup:	135
			Communication	dynamic 1)
		Client	Communication	dynamic 1)

	Modicon controller (Modicon channel MODBUS TCP/IP)			502

¹⁾ Dynamic port:
The Microsoft Windows operating system automatically assigns the relevant service a free port that can be between Port 1024 and 65534. You must enable this area when using a firewall.
²⁾ Archiving:
Requirement for archiving via an Ethernet network is that the server is enabled.
³⁾ PROFINET
Communication via PROFINET must be activated in the "Control Panel", in the "PROFINET" Settings dialog.
Note:If you change the ports of the Sm@rtServer, you must change the links accordingly in the HTML pages used. More information on changing HTML pages is available in the Help system of WinCC flexible under "Example: Configuring an integrated web server".
