    摘要： A system to determine the usage of loading dock equipment such as a dock leveler, a vehicle restraint and a barrier gate to provide an output indicative thereof. For each loading dock component mounted at a loading dock in an operable configuration whose operation is to be monitored, sensor outputs are used to provide data accumulated by PLC's located in a control panel associated with the loading dock. When operation of a piece of equipment is initiated the occurrence delivers an output signal to the PLC. A counting circuit accumulates a count of the output signals. The panel has displays in the form of lights and screens and the data maybe read out by means of a hand held unit for display and/or programing or delivered to a remote PC by appropriate cable.

    摘要： Embodiments include systems and methods of in-line mixing of hydrocarbon liquids and/or renewable liquids from a plurality of tanks into a single pipeline based on density or gravity. According to an embodiment, a method of admixing hydrocarbon liquids from a plurality of tanks into a single pipeline to provide in-line mixing thereof includes initiating a blending process. The blending process including continuously blending two or more liquids over a period of time, each of the two or more liquids stored in corresponding tanks, each of the corresponding tanks connected, via pipeline, to a blend pipe thereby blending the two or more liquids into a blended liquid. The method further includes determining a density of each of the two or more liquids to be blended during the blending process. The method includes, in response to a determination that the blend process has not finished and after the passage of a specified time interval, determining an actual blend density of the blended liquid, via a blend sensor connected to the blend pipe, the blended liquid flowing through the blend pipe and in contact with the blend sensor, and the specified time interval less than a total duration of the blending process. The method includes determining an actual blend density of the blended liquid, via a blend sensor connected to the blend pipe, the blended liquid flowing through the blend pipe and in contact with the blend sensor, and the specified time interval less than a total duration of the blending process; comparing the actual blend density with a target blend density; and in response to a difference, based on the comparison, of the actual blend density and target blend density determining a corrected ratio based on each density of the two or more liquids, the actual blend density, and the target blend density and adjusting, via one or more flow control devices, flow of one or more of the two or more liquids, based on the corrected ratio.

    摘要： A configuration of control device capable of linking control applications even in a control system that combines a control device with another control device is provided. A first control device includes: a first program execution part outputting a first control command at every first cycle; a parsing part parsing at least a part of a first application program at every second cycle to sequentially generate an internal command; a command calculation part outputting a second control command at every first cycle according to the internal command generated by the parsing part; and an arbitration part managing a parsing process performed by the parsing part. The arbitration part adjusts an output timing of the second control command according to the internal command generated by the parsing part in response to notification of a timing from the second control device.

    摘要： A method for controlling a batch process recipe, having a first recipe phase and a recipe phase step enabling condition is described, wherein a function module assigned to the first recipe phase is executed by a programmable controller and wherein a first setpoint value and a first actual value are stored in the first recipe phase. Measures are proposed whereby in the context of recipe creation particular functionalities are implemented graphically and therefore visibly for the user without it being necessary to adapt a function module running in the programmable controller.
