PAA Process image of outputs èprocess image.
Process image The process image is part of a controller's system memory. At the start of
the cyclical program, the signal states of the input modules are transferred
to the process image for the inputs (PII). At the end of the cyclical program,
the process image for the outputs (PIO) is transferred to the output mod-
ules as a signal status.
