In the example above, the stoppage occurred in OB 23 when processing the

STEP 5 statement at the absolute memory address "0064 - 1 = 0063".

OB 23 (QVZ error OB) was called in FB 5 at the relative address "0008 -

1 = 0007".

The data block DB 100 was opened in FB 6. When the CPU went into the

stop mode, data block DB 13 was valid.

Data block DB 13 was opened in FB 5.
