摘要： A process plant includes a safety system that is physically and logically integrated with a process control system such that the safety system and the process control system can use common communication, diagnostic and display hardware and software within the process plant while still providing functional isolation between the safety system controllers and the process control system controllers. This integrated process control and safety system uses a common data communication structure for both the safety system and the process control system so that applications can send data to and receive data from devices in either system in the same manner, e.g., using the same communication hardware and software. However, the common data communication structure is set up to distinguish process control system devices from safety system devices using tags, addresses or other fields within the messages sent to or received from the devices, which enables data associated with the process control system to be distinguishable from data associated with the safety system, thereby enabling a diagnostic application within a user interface to automatically treat this data differently depending on the source (or destination) of the data.

摘要： A voter function block, which can be integrated into a function block diagram programming environment in a process plant control or safety system, implements voter logic in conjunction with providing operational and maintenance overrides which may be set to override individual inputs to the voter function block as well as to override the output of the voter function block. The voter function block, which is easy to create, use, test, debug and document, includes one or input limit detection units which detect if a particular redundant input has reached a specified limit indicating a condition within the process plant, an override unit that may be set by a user to override the consideration of that input in the voting function, a voting logic entity that determines if a trip condition exists based on the values of the valid or non-inhibited inputs, and an inhibit block that may used to override the output of the voter logic block during, for example, a startup or other operational condition. The voter function block may be integrated into a process control or safety system by being communicatively connected to other function blocks, such as to analog or digital input function blocks, analog or digital output function blocks, control function blocks, cause and effect function blocks which implement cause and effect logic, etc. Within the process control or safety programming environment.

摘要： Secure data write apparatus and methods for use in safety instrumented process control systems select a parameter associated with a process control element within the process control system and send first data associated with the parameter to the process control element. A confirmation associated with a request to write the first data to the process control element is received from a user and the second data is sent to the process control element in response to receiving the confirmation. The first and second data are compared at the process control element and the first or second data are written to a location in the process control element associated with the parameter if the first and second data are at least substantially identical.

摘要： A process plant includes a safety system that is physically and logically integrated with a process control system such that the safety system and the process control system can use common communication, configuration hardware and software within the process plant while still providing functional isolation between the safety system controllers and the process control system controllers. This integrated process control and safety system uses a common data communication structure for both the safety system and the process control system so that the configuration application can send data to and receive data from devices in either system in the same manner, e.g., using the same communication hardware and software. However, the common data communication structure is set up to distinguish process control system devices from safety system devices using tags, addresses or other fields within the messages sent to or received from the devices, which enables data associated with the process control system to be distinguishable from data associated with the safety system, thereby enabling a configuration application within a user interface to automatically treat this data differently depending on the source (or destination) of the data.

摘要： A control system, a safety system, etc., within a process plant may each use one or more state machine function blocks that can be easily integrated into a function block diagram programming environment. Such a state machine function block may include one or more inputs, which may or may not cause a state machine implemented by the state machine function block to change states. The state machine function block may also include a plurality of outputs. Output configuration data associated with the function block may indicate values of the outputs of the function block for each of the states of the state machine. The state machine function block may use this output configuration data to determine its outputs when in a particular state.

摘要： The claimed system provides an I/O card that is used to interface two process controllers over a communication line that is separate from a primary communication line connecting the two process controllers to a workstation. The process controllers can access the I/O cards in a similar manner to I/O cards used to connect to field devices. In this manner, the physical hardware and software architecture does not need to be modified for inter-controller communications. Inter-controller communications can be programmed as general I/O communication.

摘要： A control system, a safety system, etc., within a process plant may each use one or more state machine function blocks that can be easily integrated into a function block diagram programming environment. Such a state machine function block may include one or more inputs, which may cause a state machine implemented by the state machine function block to change states. The state machine function block may determine a next state to which it is to transition based, at least in part, on data indicative of the next state to which to transition, if any. The configuration data may be retrieved from a database based on the current state of the state machine and at least one of the inputs. The state machine function block may also include one or more outputs that are generated based on the state of the state machine.

摘要： A process control or safety instrumented system uses function block logic to coordinate the logic within the process control or safety instrumented system with operational states of field devices, even when these operational states are initiated externally to the process control or safety system. Logic within input or voter function blocks associated with field devices may monitor and determine when the associated field devices are being put into testing or calibration modes and may automatically initiate appropriate bypass or override functionality in response to such detected field device configuration states. Likewise, the function block logic may automatically remove the bypass or override functionality when the field devices are placed back into their normal operational configuration states. This automatic initiation of bypasses and overrides helps to prevent a safety system within a process plant from initiating a shut-down procedure as a result of a device test initiated manually by, for example, a hand-held device attached to a field device. Likewise, the automatic removal of bypasses and overrides helps to prevent a safety system within a process plant from failing to operate properly because a user forgot to manually remove a bypass or override that was set up to allow a device test.

摘要： A process control or safety system within a process plant uses one or more testing blocks to effect the timely and safe operation of on-line testing routines within field devices, such as valves, used in the process control or safety system. These testing blocks, which are easy to implement and to place in the process control or safety system, enable the periodic or on-demand testing of field devices to be integrated into the normal and on-going operation of the process control or safety system without causing scheduling or connection problems and without the need to rely on maintenance or other personnel, thereby providing better monitoring of the operational status of the field devices used within the process control and safety systems. This functionality is especially important in safety systems, in which it is desirable to timely monitor or assess the operational status of the devices used to shut the process down when an unsafe condition arises, so as to assure that initiation of a shut down by the safety system actually results in a shut down of the system.
