General information
The following information is required for the STEP 7 configuration of the CP:
● Own phone number of the CP (required for TeleService)
● Authorized phone numbers
Phone numbers of the nodes that are allowed to send an SMS to the CP.
● APN
Name of the access point (APN) from the mobile wireless network to the Internet
(information from the mobile wireless network provider)
● APN user name
User name for the access point of the mobile wireless network provider
● APN password
Password for the access point of the mobile wireless network provider
● Node number of the SMS master station (SMSC) when using SMS
● PIN of the SIM card
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.
