PLCSim

Hi,

I have configured PLCsim correctly (i mean with the good adress, import mnemonics). When i'm trying to launch the run mode for my CPU after 3 seconds the run button stop to flash for no reason ( i haven't forced values yet). When i go in my program with the online mode it's appears that my CPU is stopped.

Any ideas ?

Hello,

look in the diagnostic buffer when you are online on the simulated PLC, here the reason for stop is logged.

Christoph

go online

open online&diagnostic of the PLC

open diagnostic buffer

Apparently it's a problem of CPU. It's not the same in my program and in PLCSIM. 

I'm working with PLCSIM 5.3, how can I change my CPU version on PLCSIM ?

?

which PLC you have in the program?
Normaly if you start PLCSIm from the project the plc you have created in the project is started.

create a new PLCSIm Project and create the PLC and version you need.

in my program i have 6ES7 315-2EH14-0AB0

On PLC SIM  6ES7 841-0CC04-0YE0

Sems somebody had the same problem :

Hello,

this should not be the problem.

Where you have switch the PLC to RUN? In the PLCSIM directly?

Have you look in the diag buffer?

Regards

Christoph

yes directly in PLCSIM.

And i have the information that the CPUs are not the same thank to the buffer. it tells me that the cpu is stopped due to an error.

Perhaps you want  a screenshot of the buffer ?
