Configuration and operation
4.4 Information required for configuration
Note
Configured PIN and PIN on the SIM card must match.
If you enter the PIN of the SIM card of the CP incorrectly during STEP 7 configuration and
download the station, the CP stores the wrong PIN. An incorrectly entered PIN is transferred
by the CP only once so that the SIM card is not locked.
If you change the PIN of the SIM card externally to the incorrectly configured PIN (new PIN
of the SIM card = incorrectly entered PIN in STEP 7), the CP rejects this PIN again without
checking it.
Note
Solution after entering an incorrect PIN:
To avoid the PIN being rejected by the CP again, use a PIN that is different from the
incorrectly entered PIN. Procedure:
• If the PIN of the SIM card was not changed:
– Configure the PIN in STEP 7 with the PIN of the SIM card.
– Reload the station.
• If the original PIN of the SIM card was changed externally to the PIN that was previously
incorrectly entered in STEP 7:
– Change the PIN of the SIM card externally to a new PIN that has not yet been
– Change the configured PIN in STEP 7 to the newly assigned PIN of the SIM card.
– Reload the station.
Information required for telecontrol communication
The following information is required for the STEP 7 configuration of the CP:
● Address of the telecontrol server
– IP address
– Name of the telecontrol server that can be resolved by DNS
– IPT listener port of the telecontrol server. Default setting: 55097
If only connections with TCSB are used (no direct communication), a dynamic IP address
can be assigned to the CP by the Internet service provider.
For addressing a redundant TCSB system, refer to the section Partner stations >
Telecontrol server (Page 53).
● DNS server address(es)
You require the DNS server address if you address the telecontrol server using a name
that can be resolved by DNS and the DNS is not operated by the network provider. You
configure DNS in the parameter group "DNS configuration":
– If you do not specify an address, the DNS server address is obtained automatically
– If you want to use a different DNS server, enter its IP address. In this case, DNS
