I've downloaded theMODBUS_PN_CPU_EXAMPLE_V12 from the website. I've then changed the device ET200S-IM151-8 PN/DP to aET200S-IM151-8F PN/DP to be able to download the software to the ET200S F type CPU.

When compiling the software and hardware no error is given, but when loaded the software I get error messages about every FB:

(same message for FB102, FB103, FB105, DB11, DB12, etc. Even OB1 and OB100 gives the same error

--> Cannot load block CYCL_EXC (OB1). Error code 0x117.,5/9/2014,12:48:51 PM

--> Cannot load block COMPLETE RESTART (OB100). Error code 0x117.,5/9/2014,12:48:51 PM

I'm new to the Tia Portal, so maybe I'm missing something or it just isn't possible to convert from a ET200S-IM151 8 to a IM151 8F?

Are both CPU's compatible? With this I mean if you create a project for a IM151 8, can it be converted to a IM151 8F? It has more memory, so you would expect it can...

kind regards

I should install an MMC before trying to download...
