DIAG LED blinked red and the NETWORK LED remained on

Hello,

I'm having a similar problem.

Initially, I created a project on TIA v13 SP1 Upd9 using a CPU 1214C (6ES7 214-1AG40-0XB0) FW 4.2.2 and a CP1243-7 LTE (6GK7 243-7KX30-0XE0) FW 3.1.24.

The DIAG LED blinked red and the NETWORK LED remained on (red color), meaning "Missing SIM card", according to the manual (C79000-G8976-C381-01, page 29).

I tried at least 3 different SIM cards, with no success. I used the same cards on a SCALANCE M874-3 (6GK8574-3AA00-2AA2) and they worked fine.

I installed TIA v15 on a computer with Windows 10 build 1803 and converted the project, replacing both CPU and CP with the correct FW (v4.2 and v3.1, respectively), downloaded the project, but the CP continues to show DIAG and NETWORK LEDs.

The antenna is connected to the CP 1243-7.

Any suggestions?

Thanks in advance.

Split from CP 1243-7 DIAG LED FLASHING RED.

huggy_d1, thank you for replying.

The "Diagnostic status" of the CP 1243 says that the Module exists and it is OK.

Still in the "Online & diagnostics" tool, the section "Mobile wireless interface" section says that the mobile wireless interface is not responding.

I activated the advanced CP diagnostics, according to page 68 of the CP 1243 Operating Instructions manual. Two things have drawn my attention:

1 - The TAG "Mobile wireless signal quality (LED) has the value "3", meaning "Waiting for PIN / no PIN configured", according to the manual. I tested different SIM cards, and even without a card in the slot the value remains the same. As I said earlier, the LED blinking pattern means that the SIM card is missing, so the correct value for this TAG shouldn't be "2"?

2 - I configured the Ethernet Interface of the CP module with a fixed IP, but the TAG "Current IP address" shows the address "0.0.0.0".

I'm attaching some screenshots to clarify the data posted above.

Any thoughts would be appreciated.

huggy_d1,

Through a mobile phone, I activated the PIN code in one of the SIM cards tested, entered the same code in the "Mobile wireless settings" section of the CP hardware configuration, and checked the box "Activate PIN". I did the test with and without the phone number entered. Still with no success.

Hello All

I am facing the same problem,

What I got to know through CP disgnostics is that in network status the value is shown as 3

which means :- Waiting for Pin/No pin configured or Waiting for pin entry.

Now for my SIM what i am using I have made that SIM security enable through phone and the same PIN number i gave in configuration by activating the PIN but still no success.

The LED's are still the same way..but yes I got Mobile Wireless Interface as "OK"  and signal quality as

No Network <110 DBM

So are there any more settings required on cp side for PIN and why it is asking for PIN on first hand when earlier it was working all fine.?????????????

so problem is still there.

Please help ,I need to solve this problem as customer is struggling

 Dear all,

I met this issue too. It was totally working fine before this.

I check program and SIM's network by my personal H/P, both were fine.

PLC's online diagnostics status without any ERROR/WARNING.

I also try to use another SIM and the issue was same (DIAG LED blinking with RED, NETWORK LED keep RED) that show 'Missing SIM Card'.

Anyone can help on this...?
