Process image

Definition of process image
The process image is a component of the AS-i master system memory.
At the start of the cyclic program, the signal states of the inputs are transferred to the
process image of inputs.
At the end of the cyclic program, the process image of the output is transferred to the slave
as a signal state.
Input process image (PII)
The table below contains process data and a process image of inputs DI 0 to DI 3:
