    摘要： The present invention discloses a method of identifying elements in a plurality of data table files of a programmable logic controller using symbols to represent the addresses thereof. This, and other techniques, provide means for managing and economizing the allocation of memory. The software package tracks which of the elements are represented by symbols and which of the elements are available. Symbols can be attached to element addresses by the user displaying a list of previously defined symbols and selecting a symbol from the list. Symbols can be attached to element addresses by the user selecting a particular Data Table file and simply requesting the next available element address from the file. Symbols can also be automatically attached to elements in new Data Table files. The user specifies the file type for the new Data Table file and the software package creates the new file. At the same time, the software package will automatically attach the symbol to the address of the first element in the new created file. The user has the option of manually attaching symbols to elements in the Data Table files. The user selects a Data Table file and the software package displays the contents of the file on the screen. The user positions the cursor on the desired element and the software package attaches the symbol to the address of the element.

    摘要翻译： 本发明公开了一种使用符号来表示其地址来识别可编程逻辑控制器的多个数据表文件中的元素的方法。 这和其他技术提供了管理和节省存储器分配的手段。 软件包跟踪哪些元素由符号表示，哪些元素可用。 符号可以通过用户显示先前定义的符号的列表并从列表中选择一个符号来附加到元素地址。 符号可以通过用户选择特定的数据表文件并简单地从文件请求下一个可用的元素地址来附加到元素地址。 符号也可以自动附加到新数据表文件中的元素。 用户指定新数据表文件的文件类型，软件包创建新文件。 同时，软件包将自动将符号附加到新创建的文件中的第一个元素的地址上。 用户可以手动将符号附加到数据表文件中的元素。 用户选择数据表文件，软件包在屏幕上显示文件的内容。 用户将光标定位在所需的元素上，软件包将符号附加到元素的地址。

    摘要： The present invention provides productivity aids for ladder logic programs for Programmable Logic Controllers (PLCs). The present invention discloses a software package embodying a method of creating custom screens for displaying the values and status of bits and words in a PLC as a ladder logic program executing therein is monitored. Any combination of bits and words can be displayed by the custom screens. This Custom Data Monitor function is designed to simplify troubleshooting by giving the user the tools to develop screens that act as windows into user-selected Data Table locations in the PLC.

    摘要： The disclosed embodiments relate to simulation of one or more PLCs 302 which are to be physically implemented on conjunction with other devices 304 306, such as sensors or other devices 304 which provide information or signals to the PLC and/or actuators or other devices 306 which are controlled or otherwise receive information or signals from the PLC 302, e.g. to monitor and/or control various industrial machines or processes. The characteristics, physical or other attributes, of the interconnection(s) 308 between the PLC 302 and the other devices 304 306 are modeled 116 118 120 and simulated to ensure that the PLC 302 behaves in a manner consistent with the characteristics of the interconnection 308. Accordingly, using the disclosed embodiments, simulation of a PLC 302 will provide a more accurate representation of the expected actual operation thereof in the actual environment.

    摘要： A safety system programmable logic controller provides for cross connection of inputs and outputs of separate independent control modules through the use of virtual wire connections passing as messages on a single logical backplane. The backplane executes a high level protocol that provides wire-like indications of communication failures mimicking those of separate physical wires.
