4.5 Telecontrol communication (CP 1542SP-1 IRC)
CP 1542SP-1, CP 1542SP-1 IRC, CP 1543SP-1
48 Operating Instructions, 01/2017, C79000-G8976-C426-03
Address information required by the CP
You will find information about the address information of the communications partner
required by the CP in section Partner stations (Page 52).
Ethernet interface (X1) > Advanced options
Configure the generally available parameters just as for every other Ethernet interface:
● General data (name etc.)
● Addresses and possibly routers
● Port settings
● Access to the Web server
Below you will find only the description of the specific parameters for telecontrol
communication.
TCP connection monitoring
The setting made here applies globally to all TCP connections of the CP. Note the option of
overwriting the value configured here for individual communications partners, see below.
●
TCP connection monitoring time
If there is no data traffic within the connection monitoring time, the CP sends a keepalive
to the communications partner.
Permitted range: 1 ... 65535 s. Default setting: 180
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", compare section Partner stations (Page 52). The function can only be
disabled by entering 0 (zero) for the partners.
●
TCP keepalive monitoring time
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: 1 ... 65535 s. Default setting: 10
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 only be disabled by entering 0 (zero) for the partners.
