Hello,

I Have done everything and now I can restart my CP card but my CP card still cannot communicate with my CPU, it still gives me the same error message. Could there be a fault on my memory card that I have put into the CPU, because now when I put the memory card into the CPU it goes into stop mode and throws out a SF.?

 Hi,

I know this is an old post but i am in the same situation.

I am trying to communicate to the CP via the 343-1 but get the same error as the OP.

Any guidance would be gladly accepted.

 and what you want to do? What communications to CP you mean?

Hello,

ok but what type of communication? For download/monitoring to/with CPU or user defined communication between devices? If you see on screenshot you have difference between Online and Offline cfg so check properly your HW cfg if it is same as real PLC order number and other compoinents. Be careful that also firmware can be different...

Hello,

in PG/PC interface you need set in Access type S7Online (Step7) and in interface set there your used LM ETH card with ISO or TCP (also Auto yo can try) but you need to have set your IP PC to same subnet as Lean CP is configured, in case of TCP is set. try use ISO or Auto but your used LM card. Then try go diagnostic in menu and try connect.

Hello,

with Download/Upload and Monitoring options you don't need any blocks, do your preffered option as usually. In case you want exchange data between PLC and other device then due selected system of communication some blocks need to be used and configured.

Hello,

this is your new HW cfg? In case you want download to CPU, is your complete HW compilled and without any error? In case yes, then clcik on CPU or Icon on HW cfg and download to CPU, screen with selection of download interface can show. I recommend maybe set for first that .ISO protocol or is that CP configured already previously with some IP? That Diagnostic I mean inside main menu, not inside PG/PC interface, also download (if you want to do this) is there as option. On other case, for first configuration maybe first download with correct cfg is required via MPI and then IP is set inside CP what then can be used for download and other options under .TCP selection. Look to upper link with Hoseini's post for other check. Maybe also MPI address is set with CP and in case of also same as CPU has set, it can be problem. Look also to CP cfg and set all correctly with next compile and download after.

Hello,

really not sure, there are many settings you need set correctly, also I see you want Upload to PC from real PLC? Then really not sure what you want to do, I said that MPI addresses need to be set correctly and must be unique. Really not sure, hope you know what you do, do you have backups for sure? What I know was problem with some ETH LM cards on NTB with not correct driver but you have already some successful connection previously with some similar cards and this your NTB?

Hello,

again pls, if you compile complete your prj, I see that you can't download with errors in HW/PRG cfg...
