摘要： A system includes a computing cloud having at least one data storage unit and at least one processing unit. The computing cloud is configured to receive information associated with at least one process collected by an industrial tool, archive the process-related information, analyze the process-related information, and instruct a client device on a type of data to be cached by the client device. §The industrial tool could include a sensor configured to collect data associated with industrial equipment. Also, the client device may be associated with a local environment, the sensor may be configured to capture sensor readings at a specified interval, and the local environment may be configured to use a subset of the sensor readings. The client device can be configured to provide all of the sensor readings to the computing cloud.

摘要： A method includes receiving a representation of an industrial site and selecting a plurality of locations in the representation. The method further includes predicting a level of wireless coverage of the industrial site based upon the selected locations and comparing the level of wireless coverage to a predetermined coverage criterion. Based upon a result of the comparison, the method repeats the steps of selecting, predicting and comparing.

摘要： A system for, and method of, disseminating a functional block to a redundant controller for a real-time process control system and a real-time process control system incorporating the system or the method. In one embodiment, the system includes: (1) a dynamically linkable library object associable with the functional block and (2) a shared memory, associated with at least two nodes of the redundant controller, that receives the dynamically linkable library object and the functional block and provides concurrent access thereto by both the at least two nodes to ensure consistent memory images therefore without requiring one of the at least two nodes to be taken off-line.

摘要： A primary (first) and secondary (second) slave (IOP) collect input pulses from a field device, each independently maintaining an interim total number of pulses. A master controller executes a method for maintaining the total number of pulses for the entire process by requesting the interim total number of pulses, a process variable, and a flag from the first IOP by the controller. If the flag indicates no anomaly in the interim total number of pulses or the process variable, the master controller determines a new interim total number of pulse and the process variable since the previous request. The new interim total number of pulses and the process variable is saved in a temporary holding area, such that upon a failover of the first IOP, differences in the interim total number of pulses transmitted by the second IOP can be handled without causing an error in the total number of pulses for the entire process being maintained by the master controller.

摘要： Data bases of a first and second input output processor (IOP), which are primary and secondary slave IOPs, respectively, are sychronized, and communications by a master controller is made only to the first IOP. Each IOP is executing the same tasks utilizing their own clocking systems. A method for maintaining synchronization between the first and second IOP comprises the steps of transmitting a message addressed to the first IOP by the master controller. The first IOP receives the message for subsequent execution. Receipt of the message is acknowledged by a transmission back to the master controller the acknowledge message including a message number. The second IOP eavesdrops on the transmissions between the master controller and any of the IOPs on the network. Upon recognizing that the message is addressed to the corresponding first IOP and that the message is of a predetermined type, the second IOP receives the message for subsequent execution. The second IOP verifies the message number in the acknowledge message, the message number being determinable by the second IOP, such that when both the first and second IOP complete execution of the received message which results in an update of the respective data bases, both data bases continue to contain the same information thereby maintaining synchronization.

摘要： A method by which redundant network interface modules (NIMs) interconnecting the communication buses of two local area networks communicate with one another at predetermined time intervals over the communication buses of both networks. A first NIM of a redundant pair of NIMs is designated as the primary and a second NIM of the redundant pair is designated as the secondary. Contents of the information communicated between the NIMs over the communication bus of the first network includes the status of the transmitting NIMs ability to communicate with the second network and the information communicated between the NIMs over the communication bus of the second network includes the status of the transmitting NIM's ability to communicate with the first network. Based on the information exchanged, the failure of the NIMs to communicate as scheduled, and the internal status of each NIM as understood by that NIM, the NIMs decide when failover from the primary NIM to the secondary NIM occurs.
