  In many industrial sectors such as factory automation and process control
sensor redundancy is required to ensure reliable and highly-available
operation. Measured values from N-redundant sensors are typically subjected to
some voting scheme to determine a value which is used in further processing. In
this paper we present a voting framework which allows the sensors and the
voting scheme to be configured at systemconfiguration time. The voting scheme
is designed as a Real Time Ethernet profile. We describe the structure of the
voting system and the design and verification of the framework. We argue the
applicability of this sub-system based on a successful prototype
implementation.
