Abstract
In distribution networks for safety sensors and devices, aspects of the invention provide routing individualized status signals in parallel to potential safety sensor locations in addition to serially routing safety signals to provide substantially increased protection. A shorting plug that electrically shorts together an individualized status signal to a voltage reference level at a safety sensor location, in addition to electrically shorting together the safety signals for electrical continuity, provides individualized status information for each potential safety sensor location in addition to the serial safety information provided by the safety signals. Another aspect of the invention provides a remote monitoring device coupled to one or more adapter ports, with each adapter port coupled to one or more safety sensors, wherein adapter ports are coupled via cabling with cable endings of the same type, thereby preventing circumvention of a safety sensor simply by coupling together adjacent cables.
