1. A computer-implemented method of enabling configuration of a configurable voting block for a process control system in a process plant, the configurable voting block having a voting scheme associated with a set of inputs generated by a set of field devices to control operation of at least one device within the process plant, the method comprising:
receiving, via a user interface, a first control selection that directs whether the voting scheme for the configurable voting block is degraded for a first instance of a first type of input of one of the set of inputs;
receiving, via the user interface, a second control selection that directs whether the voting scheme for the configurable voting block is degraded for a second instance of the first type of input of another one of the set of inputs;
receiving, via the user interface, a trip inhibit enable selection that directs whether the at least one device is inhibited from tripping automatically when a number of required votes of the voting scheme exceeds a number of votes of the voting scheme that are not bypassed or bad, wherein the trip inhibit enable selection is either a yes selection or a no selection;
configuring the configurable voting block according to the first control selection, the second control selection, and the trip inhibit enable selection;
receiving, from the set of field devices, the set of inputs; and
determining, from the set of inputs and according to the configurable voting block that was configured, whether the number of required votes of the voting scheme exceeds the number of votes of the voting scheme that are not bypassed or bad; and
based on the determining, causing the at least one device to trip automatically or be inhibited from tripping automatically.
