The mobile wireless network is selected automatically.
Note
Dial-in in mobile wireless networks with LOGO! CMR2020
LOGO! CMR2020 only dials into a GSM/GPRS network.
Dial-in in mobile wireless network with LOGO! CMR2040
As first choice, LOGO! CMR2040 attempts to establish a connection to an LTE network.
If the connection to the LTE network fails, the CMR attempts to establish a connection to a
UMTS network.
If the connection to the UMTS network fails, the CMR attempts to establish a connection to a
GSM/GPRS network.
By selecting the "Activate mobile wireless interface" check box, you make the mobile
wireless interface operational.
If the check box is not selected, the mobile wireless interface cannot be used. The mobile
wireless interface is turned off.
PIN of the SIM card
Note
SIM card without PIN
The CMR also works with SIM cards without a PIN. In this case, do not make an entry in the
"PIN of the SIM card" input box.
Entry of an incorrect PIN
The last entered (incorrect) PIN is saved. This means that when changing the configuration
(except the PIN) or when restarting the CMR, no further PIN entry attempt is used up.
For this reason, do not change the PIN of the SIM card to the previously stored incorrect PIN
outside the CMR.
Locking if the PIN is entered correctly
Enter the PIN correctly. If you enter the PIN incorrectly three times, the SIM card will be
locked. You should also refer to the information in the section Insert the SIM card and enter
the PIN (Page 44).
Unlocking the SIM card
Unlocking the SIM card is described in the section Insert the SIM card and enter the PIN
(Page 44).
