摘要： A method and circuit for precisely synchronizing clocks in separate nodes on a communication network is provided by adjusting timestamps and related data in network messages. The circuit will allow a daisy-chain connection of the nodes and will forward time synchronization frames while accounting for delays in a manner that does not use boundary clocks, but does not depart from the IEEE 1588 standard protocol. The delays will be added on the fly to synchronization packets and the IP checksum and frame CRC will be adjusted. Deterministic data delivery and redundant data paths are also provided in a full duplex Ethernet network.

摘要： A transmission schedule is overlaid on the Ethernet protocol to allow use of this readily available high speed protocol for transmission of I/O data communicated in an industrial control environment and requiring a high degree of determinism. Scheduling improves load leveling and bandwidth utilization and by producing a more consistent delay may be teamed with time synchronization to produce more accurate clock synchronization.

摘要： In accordance with a first preferred embodiment, a control method comprises monitoring a position of a motion control axis and controlling an output device responsive to the position of the motion control axis. The controlling step further includes latching a cam element that controls the output device, and unlatching the cam element that controls the output device. The manner in which the latching step is performed and the manner in which the unlatching step is performed are configurable in a programming interface. The programming interface is capable of receiving a latch position for the cam element and an unlatch position for the cam element. The programming interface is further capable of receiving additional configuration information to configure the manner in which the latching step is performed and different additional configuration information to separately configure the manner in which the unlatching step is performed. The latching step and the unlatching step are performed in the manner configured in the programming interface. In accordance with another preferred embodiment, a programming interface for a control system comprises an axis motion control instruction and an output cam instruction. The axis motion control instruction is executable to control movement of a motion control axis. The output cam instruction is executable to control a state of an output device responsive to a position of the motion control axis. The programming interface permits the axis motion control instruction and the output cam instruction to both be used in a common user program.

摘要： Systems and methods that vary multiple data sampling rates, to collect sets of data with different levels of granularity for an industrial system. The data for such industrial system includes sets of data from the “internal” data stream(s) (e.g., history data collected from an industrial unit) and sets of data from an “external” (e.g., traffic data on network services) data stream(s), based in part on the criticality/importance criteria assigned to each collection stage. Each set of data can be assigned its own unique data collection rate. For example, a higher sample rate can be employed when collecting data from the network during an operation stage that is deemed more critical (e.g., dynamic attribution of predetermined importance factors) than the rest of the operation.

摘要： Systems and methods that manage resources and distribution thereof within an industrial system. Such an automated and dynamic allocation service can allocate resources from pools of resources available to the industrial system, and hence supply an efficient operation (e.g., adding/subtracting resources dynamically based on usage). A plurality of allocation rules and/or algorithms for resource types can be predetermined, and/or dynamically trained by the allocation service. The data employed for the industrial system includes sets of data from the “internal” data stream(s) (e.g., history data collected from an industrial unit) and sets of data from an “external” (e.g., traffic data on network services) data stream(s), based in part on the criticality/importance criteria assigned to each collection stage.

摘要： Systems and methods that correlate among disparate pieces of synchronized data, collected from an “internal” data stream (e.g., history data collected from an industrial unit) and an “external” data stream (e.g., traffic data on network services). A process trend component that determines/predicts an outcome of an industrial process and facilitates diagnostics/prognostics of an industrial system. Accordingly, relations among various parameters can be discovered (e.g., dynamically) and proper corrective adjustments supplied to the industrial process. Such enables a tight control and short reaction time to process parameters, and for a modification thereof.

摘要： Systems and methods that displays available relationships between internal and external data streams. A coordination component can collect and analyze both the “internal” data stream(s) and the “external” data stream(s) simultaneously, and a visualization component can present a form of a visual cue, on a collection of history data and network data. Accordingly, instead of merely storing data values as function of time, other non-time series correlation states can be employed dynamically to represent data to the user.

摘要： An industrial controller has an I/O scanner that may scan I/O modules at differing rates depending on the intrinsic bandwidth of the controlled process variable. The user defines an update rate for each I/O module reflecting the bandwidth of its associated variable. The scanner continuously updates a table of I/O events for each I/O module or I/O rack listing permissive and mandatory I/O execution times associated with each event. Using this event table, the I/O scanner determines the next I/O module to be serviced. If the event cannot be serviced on schedule, indication of an event slip is reported to the controller.
摘要翻译：工业控制器具有I / O扫描器，可以根据受控过程变量的固有带宽以不同的速率扫描I / O模块。用户为反映其关联变量的带宽的每个I / O模块定义更新速率。扫描仪不断更新每个I / O模块或I / O机架的I / O事件表，列出与每个事件相关联的许可和强制性I / O执行时间。使用此事件表，I / O扫描器确定要维修的下一个I / O模块。如果事件无法按计划进行维修，则会向控制器报告事件单。
