●
The partner number for the telecontrol server is assigned automatically by the system if
telecontrol communication is enabled.
●
The station address of the telecontrol server is assigned automatically by the system if
telecontrol communication is enabled.

IP address of the telecontrol server
If the CP is connected to a TCSB redundancy group (TCSB V3), here configure the public
IP address of the DSL router via which the telecontrol server can be reached from the
Internet. Set the port forwarding on the DSL router so that the public IP address (external
network) is led to the virtual IP address of the TCSB server PCs (internal network). The
station does not therefore receive any information telling it which of the two computers of
the redundancy group it is connected to.
●
When the function is enabled, the connection to the communications partner (telecontrol
server) is monitored by sending keepalive frames.
The TCP connection monitoring time is set for all TCP connections of the CP in the
parameter group of the Ethernet interface. The setting applies to all TCP connections of
the CP.
Here in the parameter group "Partner stations > Telecontrol server", the globally set TCP
connection monitoring time can be set separately for the telecontrol server. The value set
here overwrites the global value for the telecontrol server that was set in the "Ethernet
interface (X1) > Advanced options > TCP connection monitoring" parameter group.
