Firewall settings
The TwinCAT PLC library IEC 60870-5-104 sub station (slave/server) 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 must be considered by using a firewall.
Description | Type | Protocol | Port |
|---|---|---|---|
IEC 60870-5-104 telecontrol protocol | Protocol | TCP | 2404 |
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.

Remember if you use an Embedded Controller without display and USB: Activate the port for Remote Display (Windows CE) or Remote Desktop (Windows XP / Windows Vista) in the firewall. Otherwise, you have no way to manage the computer via the network. |
