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.

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 communication bus suitable for use in a hazardous area of a process plant includes a first transmission path adapted to communicate electrical signals in a first direction, and a second transmission path adapted to communicate electrical signals in a second direction. A safety device is coupled to each of the first and second transmission paths and includes a control unit adapted to detect a fault condition associated with the communication bus. The safety device further includes a switch unit adapted to interrupt the flow of electrical signals along each of the first and second transmission paths in response to the detected fault condition. In this manner, the detection circuitry of the communication bus automatically reduces or prevents the occurrence of sparks or arcing in the event of a fault condition associated with the communication bus.

摘要： A handheld communicator wirelessly interfaces or communicates with individual devices in a process control system, such as field devices, controllers, etc., to wirelessly perform monitoring, maintenance, configuration and control activities with respect to those devices. The wireless handheld communicator includes a housing adapted for handheld operation, a processing unit disposed within the housing, a computer readable memory disposed within the housing and coupled to the processing unit and a display, a keypad and a radio frequency transceiver. The handheld communicator may be adapted to communicate with a host system to receive information needed to communicate with various field devices in the process plant and may then be used to wirelessly communicate with each of the various field devices directly while in close proximity to the field devices to perform monitoring and configuration activities with respect to the field devices. Thereafter, information obtained from the field devices may be wirelessly communicated to the host system or to a repository, such as a data historian or a configuration database.
