Title:
TECHNOLOGIES FOR CONFIGURING VOTING BLOCKS ASSOCIATED WITH PROCESS CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2021068433
Kind Code:
A
Abstract:
To provide techniques for enabling the configuration of a voting block for use in a process control system of a process plant.SOLUTION: According to certain aspects, the voting block may have a voting scheme that dictates an output based on a set of inputs, where the voting block may be configured parametrically using various control selections that direct the behavior of the voting scheme. In particular, a bypass degrade selection can be specified for one or more inputs that controls whether a "bypass" input degrades the voting scheme; a status degrade selection can be specified for one or more inputs that controls whether a "defective" input degrades the voting scheme; and a trip enable selection can be specified that controls whether a trip occurs automatically under certain conditions. The control selections enable the voting blocks to be configured to conform with various specifications and other requirements.SELECTED DRAWING: Figure 2
