4.1 Process data and process images
Definition of process image
The process image is part of the system memory in the AS-i master. At the
start of the cyclical program, the signal states of the inputs are transferred
to the process image of the inputs. At the end of the cyclical program, the
process image of the outputs is transferred to the slave as a signal state
.
Table
The table below shows the process data and process images:
