    • Methods and apparatus for batch process control in which a Phase Logic Module operable in accordance with the state machine model of the batch server program is embedded within a programmable controller. More specifically, a phase executed by the batch server program in a data processing device is operable in accordance with a pre-defined state machine model (typically compliant with the ISA S88.01 standard). A Phase Logic Module (PLM) is implemented within a programmable controller in accordance with the same state machine model so as to mirror the state machine operation of the batch server process within the programmable controller. The PLM is pre-implemented and standardized. Specific state logic for performing desired control in accordance with the desired batch processing is defined by a control engineer using well known languages and tools and integrated with the standard PLM state machine. These methods and structure obviate the need for the control engineer to implement customized state processing logic and the associated need to test such complex state processing logic. The PLM in the programmable controller and the phase within the batch server program communicate using a high level communication protocol to exchange state processing information. Another aspect of the invention provides for implementing a PLM in a data processing device to perform soft phase processing (a phase unrelated to process I/O equipment and rather typically related to operator interaction).
    • 用于批处理控制的方法和装置,其中根据批处理服务器程序的状态机模型可操作的相位逻辑模块嵌入在可编程控制器内。 更具体地,由数据处理设备中的批量服务器程序执行的阶段可以根据预定义的状态机模型(通常符合ISA S88.01标准)来操作。 相位逻辑模块(PLM)根据相同的状态机模型在可编程控制器内实现,以便反映可编程控制器内的批处理服务器进程的状态机操作。 PLM是预先实施和标准化的。 用于根据期望的批处理执行所需控制的特定状态逻辑由控制工程师使用熟知的语言和工具定义并与标准PLM状态机集成。 这些方法和结构避免了控制工程师实现定制的状态处理逻辑和相关的测试这种复杂状态处理逻辑的需要。 可编程控制器中的PLM和批处理服务器程序中的阶段使用高级通信协议进行通信,以交换状态处理信息。 本发明的另一方面提供了在数据处理设备中实现PLM以执行软相位处理(与处理I / O设备无关的阶段,并且通常与操作者交互相关)。

    • A L-shaped bracket having aligned vertical and horizontal slots is mounted on a telescopic stand. A frame member is positioned on a horizontal support plate of the bracket. A bearing plate extends vertically from the support plate. The support plate includes spaced apart open ended slots aligned beneath elongated vertically extending slots in the bearing plate. A J-bolt having a cap at one end and a threaded portion at an opposite end extends through the aligned slots to a position where the cap abuts the bearing plate and the threaded end portion extends down through the slot in the support plate. A bell nut is tightened on the threaded end of the bolt to draw the bolt into clamping engagement with the frame where the bolt is adjustable along the length of the vertical slot in the bearing plate to receive frames of a variable range of height.
    • 具有对准的垂直和水平槽的L形支架安装在伸缩架上。 框架构件定位在支架的水平​​支撑板上。 支承板从支撑板垂直延伸。 支撑板包括在轴承板中的细长的垂直延伸的狭槽下方对准的间隔开的开口的狭槽。 在一端具有盖和在相对端的螺纹部分的J型螺栓延伸穿过对准的狭槽到达盖抵靠支承板的位置,并且螺纹端部向下延伸穿过支撑板中的狭槽。 喇叭螺母在螺栓的螺纹端被拧紧,以将螺栓拉紧到与框架夹紧接合,其中螺栓沿轴承板中的垂直槽的长度可调节以接收可变高度范围的框架。
