Time diagram in Fig. 10.2 gives prolongation of the response time of the
programmable controller to change of the signal at the interrupt input at
synchronization of the response with the user program cycle. In the P42
process, identification of the interrupt source is performed and servicing of
the interrupt by writing to the scratchpad. Response time of the programma-
ble controller is in this case the following sum of times:
t
OA
= t
IH
(t
IL
) + t
VP
+ t
P42

KC

OC

signal at the interrupt input at processing of the response in the
P42 process and writing to the scratchpad
Time diagram in Fig. 10.3 illustrates prolongation of the response time of
the programmable controller to change of the signal when standard binary
inputs are used (interrupt inputs in the basic mode). Response time of the
programmable controller is in this case the following sum of times:
