Abstract
(EN)


A vital programmable logic device (VPD) is provided having at least two
microprocessors. The VPD is configured
to provide failsafe operation of a vital control system while operating in a
closed circuit environment. In at least one embodiment of
the present invention, railroad grade crossing signals are controlled by the
VPD.
