Diagnostics interrupt

Diagnostic interrupt
The module generates a diagnostic error interrupt at the following events:
● Channel is temporarily unavailable
● Hardware interrupt lost
● Error
● Supply voltage missing
● Parameter assignment error
● Low limit voltage violated (measuring voltage < 80 V)
● High limit value voltage exceeded
● Underflow voltage (tolerance for supply voltage) violated
● Overflow voltage (tolerance for supply voltage) exceeded
● Overload (current measurement > 12 A or tolerance overcurrent exceeded after expiry of
the tolerance time)
● Overflow of the calculated values (measured or calculated values screen exceed the
representable range of values)
