Hello Tomy; You can enable. disable and delay specific diagnostic OBs in the user program of a S7-300 or S7-400 CPU in Simatic Manager, using specialized SFCs. This is explained in Chapter 12 of the System and Standard Functions manual: https://support.industry.siemens.com/cs/ww/en/view/109751826 Outside of these "external" functions, internal evaluation of the diagnostic messages.by the user program must use the local variables of the diagnostic OB to read out the fault. In TIA Portal there are specialized functions, such as can be seen here: https://support.industry.siemens.com/cs/ww/en/view/78380025 Hope this helps, Daniel Chartier |

Now is a good point to actually start reading the manual, and understand how to use diagnostics in OB's. |
