By combining the safety functions covered in Chapter 3.1 "Overview of safety-
relevant functions" it is possible to implement completely new concepts for
operation on machines with different requirements. Intervention by the user,
e.g. in the tool magazine or setup location can be performed parallel to
production.
The most important consideration, however, is always the best possible
protection of the user while at the same time being able to use the machine for
the intended purpose.
Machine protection (machine, workpiece, tool, ...) can also profit to a large
extent from the advantages of these new possibilities.
Integrated safety technology now takes the emphasis away from purely
hardware and electro-mechanical-based solutions to those based on software
and electronics, thus gradually replacing technology that is subject to wear.
Integrated safety technology by its very concept provides intelligent system
control right down to the sensors and actuators. This results in a new
diagnostics concept that offers preventive error detection. Even with errors that
occur suddenly during production, the risk of injury to the operator and damage
to the machine can be confined to a minimum by fast error detection and
coordinated, safe shutdown.
Integrated safety technology allows
•
Optimized processes
•
Sub-processes to be able to operate in parallel
•
Simpler machine infrastructures
•
Practical machine handling concepts.
The effect on the availability
− Reduced error potential
− Longer production times
− Shorter downtimes
When applied consistently, integrated safety technology offers considerable
potential for increasing the availability.
