processes all the rungs in parallel. The speed with which a
contactor switches is thus dependent on the components
used, and ranges from 15 to 40 ms for relay pick-up and
drop-out.
With easySafety the circuit diagram is processed with a
microprocessor that simulates the contacts and relays of the
circuit concerned and thus processes all switching opera-
tions considerably faster. Safety and standard circuit
diagrams are processed in succession from the beginning to
the end. In this time, the easySafety device first runs through
the six segments of the safety circuit diagram and then the
six segments of the standard circuit diagram.
If the operands of the inputs and outputs are addressed in
the easySafety configuration, the signal states of the digital
inputs/outputs are not scanned but a memory range in the
device system memory is accessed. This memory range is
called the process image. The process image is divided into
two sections: the process image for the inputs and the
process image for the outputs.
