At a pending diagnostic the CPU interrupts the user application and
jumps to the OB 82 for diagnostic
incoming
. This OB allows you with an
according programming to monitor detailed diagnostic information via
the SFCs 51 or 59 and to react to it. After the execution of the OB 82
the user application processing is continued. The diagnostic data is
consistent until leaving the OB 82. After error correction automatically
a diagnostic
going
occurs if the diagnostic interrupt release is still active.
In the following the record sets for diagnostic
incoming
and diagnostic
going
are specified.
Record set 0 - diagnostic

n Bit 6 ... 5: reserved
n Bit 7: set at error in parametrization
