6.9 Diagnostic and interrupt
The parameterization allows you to define the following trigger for a hardware interrupt
that may initialize a diagnostic interrupt:
Counter function
n
Edge at a digital input
n
Opening the HW gate (at opened SW gate)
n
Closing the HW gate (at opened SW gate)
n
Reaching the comparison value
n
Overflow respectively at overrun upper counter limit
n
Underflow respectively at underrun lower counter limit
Frequency measurement
n
Edge at a digital input
n
End of measurement (end of the integration time)
Pulse width modulation
n
There is no process interrupt available
6.9.1 Process interrupt
The activation of the process interrupt occurs only if at the same time the
counter output is activated and "DiagProcess" is set in the basic
parameters.
A process interrupt causes a call of the OB 40. Within the OB 40 you may find the logical
basic address of the module that initialized the process interrupt by using the Local word
6. More detailed information about the initializing event is to find in the
local double word
8
.
