Process image outputs (
The pneumatics interface is the interface between the modular electrical
peripherals and the pneumatics.
The process image is part of a controller's system memory. At the start of
the cyclical programme the signal states of the input modules are trans-
ferred to the process image for the inputs (PII). At the end of the cyclical
programme the process image for the outputs (PIO) is transferred to the
output modules as a signal status.
