Why is the module INT_P issuing invalid values at the output?
Input U of module INT_P is for example connected to the output of a module DIV_R. If a division by zero occurs on module DIV_R, the module INT_P reverts to error mode and its output issues only invalid values.
A division by zero is not allowed. The operator has to make sure by means of external circuits that an undefined value is written directly on the INT_P module. When a division by zero occurs, the output ENO on module DIV_R is set to ZERO.
