Programmable Safety Circuits
Until now, safety design involved combining safety relays to configure safety control circuits. This process involved tedious wiring, and moreover,
any changes required direct modification of the wiring. The DeviceNet Safety System uses programmable safety circuits, dramatically improving
the ease of design and modification.
