6.6 Analog part - Diagnostic functions
As soon as you've activated the diagnostic interrupt release in the parametrization, the
following events can release a diagnostic interrupt:
n
Wire break
n
Parametrization error
n
Measuring range underflow
n
Measuring range overflow
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 execu-
tion 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.
