Cycle

Definition of cycle
A cycle includes the following sections:
● Update of process image partition 0 of the outputs (PIPQ 0)
● Automatic update of the process image partition 0 of the inputs (PIPI 0)
● Execution of the cyclic program
The process image partition 0 is automatically updated in the cycle. You assign the I/O
addresses to these process image partitions (PIPI 0/PIPQ 0) when you configure the I/O
modules via the "Automatic update" setting (default).
