QUESTION:  
Why can't I load the function block (FB49), that has been created with the Report System Errors function, into the ET 200S CPU?

ANSWER:  
In the HW Config, the menu item Options > Report System Errors offers two options for creating a diagnostics block. If OB82 is in the OB Configuration tab, then the resulting FB49 (default setting in the "General" tab) contains SFC13 calls. This FB49 cannot then be loaded into the CPU, because the SFC13 is not in the CPU.

SFC13 "DPNRM_DG" is not included in the delivery package of the system blocks, because the ET 200S CPUs up to and including firmware version V2.0 do not have a DP master functionality.

Therefore you should exclude the OB82 for creating the FB 49. Create a separate block for the diagnostics (OB82) of the central ET 200S modules of the CPU.

Note:
Information on the structure of the diagnostics data is available in chapter 7 "Commissioning and Diagnostics" of the manual "ET 200S IM 151-7 CPU Interface Module" in Entry ID: 12714722.
