4.12 Error Handling for the S7-200 CPU
The S7-200 CPU classifies errors as either fatal errors or non-fatal errors. You can
use STEP 7-Micro/WIN 32 to view the error codes that were generated by an error.
Select PLC > Information from the menu bar to view these errors. Figure 4-25
shows the dialog box that displays the error code and the description of the error.
Refer to Appendix B for a complete listing of the error codes.
In Figure 4-25, the Last Fatal field shows the previous fatal error code generated
by the CPU. This value is retained over power cycles if the RAM is retained. This
location is cleared whenever all memory of the CPU is cleared, or if the RAM is not
retained after a prolonged power outage.
The Total Fatal field is the count of fatal errors generated by the CPU since the last
time the CPU had all memory areas cleared. This value is retained over power
cycles if the RAM is retained. This location is cleared whenever all memory of the
CPU is cleared, or when the RAM is not retained after a prolonged power outage.
