Dear All,

I setup a simulation mode on my PG. I configured hardware. When I tried to downloaded , the system can not be done due to "Cannot Load SDB 7" Error.

PLC got stop in simulation mode.

I tried many things but can not be achieved.

Could you give me some advice.

Not : IDE Simatic Manager

Version V5.7 + SP1

Best Regards,

Hello redsky_tr,

You should regenerate the blocks generated during compilation. To do this: In the SIMATIC Manager  delete the "System Data" folder in "CPU > S7 program > Blocks".

Then regenerate the system data in "NetPro". This is indicated in the FAQ where the different types of error codes for Step 7 are listed: What is the meaning of the error codes (xxxx:yyyy) in STEP 7?

Hi,

maybe this can help, too. Its also for STEP 7 classic, not only TIA.

In STEP 7 (TIA Portal), how do you format an MMC or MC and why does a message appear saying that the SDB 7 is not loaded?

Below are reasons why you get the messages indicating that block SDB 7 cannot be loaded or that the block/OS update is too big when downloading with STEP 7 V5.x or STEP 7 (TIA Portal).
