Hello

I'am facing up a probñem reñated with HW configuration of a CP 343-1 lean

The configuration is very simple ,I want to add the Cp343 for comunícate a PLC with a SIEMENS panel by ethernet

I've checked many times the HW configuration and I'am not able to get the PLC in run ( There is no program in the PLC only OB1 and empty)

If I go to Accesible nodes ,as you can see in the attached Word ,the CP doesn't appears, so I understand HW configuration has not been transfered completly to PLC

Please help, and theank you in advance

Hello Thank you for your answer

Here attached you can see the online Ethernet diagnostics of the module

Hope this helps

IF I try to connect by MPI to the CP is not posible

Thank you in advance !

Hello,

simply if you set correct (unique) MPI address to CP, after correct download HW cfg to CPU, all MPI nodes addresses will show, mean f.ex. in download HW cfg to CPU after click search for nodes. Don't see problem with this. Ok, in first download in case of same MPI address on CPU and CP, no one or maybe one of that 2 same devices can be show. To be sure you can disconnect CP from bus and download HW cfg to CPU with option that CP configuration will be saved on CPU. This must simply work, also in my case working.

Hello  Duris_I

As you can see in the Word ,CPU and CP have different MPI adresses (  2 and 5)

But you are right ,it should be seen in accesible nodes all MPI nodes , and in my case only node 2 can be seen

Everithing seems to indicate that HW configuration was not right transfered to CPU

By performing your method ( transfer without the CP mounted) PLC goes to RUN, but when connected again in the backplane ,and after restart everything goes STOP again

Any idea??

Thank you in advance

Hello,

hmmmm only one idea going inside my head, on CP Properties set connection to Profinet Subnet, probably still you don't have it. Recompile, download with CP inside bus (now for sure you have different MPI addresses), turn off/on PLC and wait for change status on CP. Hope this can be last step for success.

Hello,

look, if your CPU has SF error, it probably point to not good HW type of CPU, modules cfg. Simply if I will not have right full cfg of CP343-1 (mean ok IP and MPI but nothing else configured), my CPU will run only with OB1 without problems, but CP can be in SF without RUN, simply in STOP. Pls check again your HW type or if all fails, what Umencho recommended to you.

Hello,

the CP343-1 lean version is very important. Plz check the module version with your soft HW configuration
