343-5 all leds flashing

tecno44 · Nov 22, 2020

Hello,
i have 315-2pn/db Cpu (315-2EH14-0AB0) V.3.2.16
and to be using with Cp343-5 profibus (343-5FA01-0XE0) V4.0

I guess I did something wrong.

I might have uploaded the wrong SDB files
SDB 1002 1003 in System Data

How can I fix this problem?
Thks for all.

Do you have 24VDC power applied to the CP343-5 on the L+ and M terminals?

In addition to sigmadeltas suggestion,..
Did you install the U-shaped connector between the CPU and and the CP343-5 ?
And between the CP343-5 and the subsequent modules ?
Did you by chance configure the wrong type of module, i.e. CP342-5 or CP343-1 ?

Yes ı have 6ES7307-1KA00-0AA0Power Supply.

There is only Power Supply, CPU and CP module on rail. Cpu and CP module combined with U Connector.

Thank You.

What does the hardware diagnostics say (not the diagnostics buffer) ?
Can you reach the diagnostics buffer of the CP343-5 ?

Can you share your STEP7 project ?
Strip out the program blocks if they are sensitive to you.

Just to be clear, make sure you connect +24VDC to the L+ terminal, and your ground (0VDC) to one of the M terminals. See the picture attached.

Great news thanks. So how can I update fw?
With Simatic Net Firmware Loader? So where can I find the .FWL file for V4.1?

User defined Bus Parameters were entered in my project. This may be my problem !!!

Response from Siemens call center

Mr. Ufuk,
SDB system data blocks cannot be intervened in any way. You can see the relevant explanation in the appendix. Flashing of all leds of the device means Module fault / system error. The fact that the CP module systematically interrupts a process and the energy fluctuates during the process cause such problems. When the stop led flashes permanently and the stop led flashes, it means start up. If the stop led or run led is constant after this step, communication can be established, otherwise, if all leds of the module are flashing, you cannot configure it because you cannot communicate.
In the attachment, the meanings of the status leds are available in the manual of the product. You can examine.
