Hello,

I have such a problem. I uploaded the program from the PLC S7-300 and ET200S CPU (Upload by TIA Step 7 Professional V13 SP1). Everything was OK, but the SCL Blocks cannot be editted and  an errors appear as attachments.

"SCL Blocks uploaded from an S7-300/400 module cannot be edited"

I think, the TIA version is not compatible so I tried uploading with different versions.

The Version Step7 Pro V13 SP1 Update 0 and Step7 Pro V13 SP1 Update 9 fully uploaded but still the same error on.

I don't have source program

If you know how to open it, please help

Thanks..

hi kyuclangtubk,

I guess this is just not supported

In s7-300 PLCs there is just the STL-code that is made from the compiler. there is no SCL-source in the CPU.

With the newer PLCs S7-1200/1500 the complete project is on the CPU and it will compiled on the CPU.

regards,

As far as I know, In STEP 7 V5 the SCL code was only in the PG and when you compile you generate a STL code which is downloaded to the CPU.

Therefore the CPU has only a STL code. I think this is why you can not upload it.

Without the SCL source, you have a problem!

It's a longshot, but can you generate source from block then import it back into your program?

Cheers

no.I have this problem yet.
