Operation Center1 Or Operation Center2 - Siemens CP 1243-1 PCC Operating Instructions Manual

5.11.3.1

Operation center1 or Operation center2

Connection to operation center
● Operation center address
The URL address of the operation center.
● Connection monitoring
When the function is enabled, the connection to the communications partner (operation
center) 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 44). The setting applies to all TCP connections of the CP.
Here in the parameter group "Operation center", the globally set TCP connection
monitoring time can be set separately for the operation center. The value set here
overwrites the global value for the operation center 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.
– Permitted range: 0 ... 65535 s
– Default setting: 180 s; if you enter 0 (zero), the function is deactivated.
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
"Operation center" and this overwrites the global value for this partner that was set in the
parameter group "Ethernet interface (X1) > Advanced options > TCP connection
monitoring".
● 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.
– Permitted range: 0 ... 65535 s
– Default setting: 1 s; if you enter 0 (zero), the function is deactivated.
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
"Operation center".
