Firewall settings

IEC 60870-5-104 uses the TCP/IP protocol for communication. It is therefore essential to make sure that the corresponding TCP port will be activated during the using of a firewall. The table below lists standard ports, that have to be considered by using a firewall.

The configuration of the Windows Firewall is done via the corresponding dialog in the control panel. For further information please see the Windows resp. Firewall documentation.
