● Partner number
The partner number is always signed by STEP 7.
● Station address / Master station address
The station address of the telecontrol server is assigned automatically by the system if
telecontrol communication is enabled.
"Connection to partner"
You will find information on the permitted ranges and defaults in the tooltips of STEP 7.
● Partner IP address
IP address or host name (FQDN) of the telecontrol server. This can, for example, also be
the FQDN of a DynDNS service.
● Connection monitoring
When the function is enabled, the connection to the communications partner 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, see also the section Ethernet interface (X1) >
Advanced options (Page 48). These settings apply to all TCP connections of the CP.
Here in the parameter group "Partner stations" the globally set monitoring time can also
be set separately for this partner. The value set here overwrites the global value for this
partner that was set in the "Ethernet interface (X1) > Advanced options > TCP connection
monitoring" parameter group.
● TCP connection monitoring time
Only with TCP: If there is no data traffic within the connection monitoring time, the CP
sends a keepalive to the communications partner.
The monitoring time is configured for the Ethernet interface as the default for all TCP
connections. The default value can be adapted individually for each connection in
"Partner stations" and this overwrites the global value for this partner that was set in the
parameter group "Ethernet interface".
The function can be disabled by entering 0 (zero) for the individual partners.
● TCP keepalive monitoring time
Only with TCP: After sending a keepalive, the CP expects a reply from the
communications partner within the keepalive monitoring time. If the CP does not receive
a reply within the configured time, it terminates the connection.
The monitoring time is configured for the Ethernet interface as the default for all TCP
connections. The default value can be adapted individually for each connection in
"Partner stations".
The function can be disabled by entering 0 (zero) for the individual partners.
● Connection mode
In the "Permanent" connection mode, there is a permanent connection to the
communications partner.
