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： 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 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： 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 cause and effect function block, which can be easily integrated into a function block diagram programming environment in a process plant safety system to implement the cause and effect logic specified by a traditional cause and effect matrix, includes a set of cause inputs and a set of effect outputs. A multiplexer within the cause and effect function block receives each of the cause inputs and is coupled to one or more state machines, with a separate state machine existing for each effect output. The multiplexer decodes each of the cause inputs and, based on the cause inputs and previously identified cause and effect matrix logic, provides a trip signal to one or more of the state machines. Upon receiving a trip signal, a state machine forces an associated effect output into a tripped or safe state. If desired, the state machine may then use one or more other signals, such as signals from a user or from the process, to transition between a set of different states used to safely return the process plant back to the normal operating state from the tripped or safe state.

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： A versatile controller that can be used as either a stand-alone controller in a relatively small process plant or as one of numerous controllers in a distributed process control system depending on the needs of the process plant includes a processor adapted to be programmed to execute one or more programming routines and a memory, such as a non-volatile memory, coupled to the processor and adapted to store the one or more programming routines to be executed on the processor. The versatile controller also includes a plurality of field device input/output ports communicatively connected to the processor, a configuration communication port connected to the processor and to the memory to enable the controller to be configured with the programming routines and a second communication port which enables a user interface to be intermittently connected to the controller to view information stored within the controller memory. When used in a distributed process control system, the controller platform may be used as a remote input/output device and the ports of this remote input/output device may be logically mapped to controllers within the distributed process control system in a manner that is different than the physical connection between such controllers and the remote input/output device.
