5.5 Interrupt response time
5.5.1 Overview
Definition of interrupt response time
The interrupt response time is the time that expires between the first occurrence of an
interrupt signal and the call of the first interrupt OB instruction. Generally valid: Higher-
priority interrupts take priority. This means that the interrupt response time is increased by
the program processing time of the higher-priority interrupt OBs and the interrupt OBs of
equal priority which have not yet been executed (queued).
