摘要： In the case of processor or installations, or both, which are monitored by sequence control from a PLC program which is produced as a contact plan (KOP), as a function plan (FUP) or as an instruction list (AWL), the AWL code of the PLC program is analyzed by machine and is prepared in the form of a knowledge base, according to the invention, in order to prepare for diagnosis. Step chain analysis and/or a transition analysis are/is carried out in order to prepare the knowledge base.

摘要： A programmable controller includes a microprocessor which operates in response to machine instructions stored in a read-only memory. A control program comprised of programmable controller-type instructions is stored in a random access memory. These are executed by translating their operation codes into the starting addresses of corresponding sets of machine instructions. In addition, one or more "universal instructions" may be contained in the control program, and when these are read from the random-access memory, they are translated to enable the microprocessor to execute a user defined set of microprocessor machine instructions. These user defined machine instructions may be stored in a read-only memory or they may be stored in the random access memory with the control program. The programmable controller may thus effectively be programmed in two languages, a programmable controller language and a microprocessor machine language.

摘要： A programmable controller (PC) which converts PC instructions directly into targeted CPU instructions, not into a macroprogram format, and stores them as an execution file. The PC stores restoration information for ladder display together with the CPU instructions, whereby the number of program steps to be executed is reduced and a ladder display can be provided. The PC also converts PC instructions written in the ladder language into restoration information restorable to the ladder language and generates them as a main processing restoration information file, then converts the PC instructions directly into targeted CPU instructions, not into a macroprogram format, on the basis of the restoration information file, and stores them as an execution file independently of the main processing restoration information file. Also, the execution file for sequence processing is separated from the main processing restoration information file for ladder display, ensuring that processing can be performed much faster without needing to judge whether a step is an execution instruction or display information. The PC incorporates conversion programs and conversion tables for generating finally required CPU instructions, whereby sequence programs can be developed in an environment where there is no computer for sequence program development. The use of such tables and programs permits function change and function addition to be made to the stored conversion tables using an accessory CRT/keyboard so that specifications can be changed as required.

摘要翻译： 可编程控制器（PC）将PC指令直接转换为目标CPU指令，而不是宏编程格式，并将它们存储为执行文件。 PC与CPU指令一起存储用于梯形图显示的恢复信息，从而减少要执行的程序步骤的数量，并且可以提供梯形图显示。 PC还将以梯形语言编写的PC指令转换为可恢复为梯形图语言的恢复信息，并将其作为主处理恢复信息文件生成，然后将PC指令直接转换为目标CPU指令，而不是以宏编程格式 的恢复信息文件，并且将它们独立于主处理恢复信息文件存储为执行文件。 此外，用于顺序处理的执行文件与用于梯形图显示的主处理恢复信息文件分离，确保可以更快地执行处理，而不需要判断步骤是执行指令还是显示信息。 PC包含用于产生最终所需的CPU指令的转换程序和转换表，从而可以在没有用于顺序程序开发的计算机的环境中开发顺序程序。 使用这样的表和程序允许使用附件CRT /键盘对存储的转换表进行功能改变和功能添加，使得可以根据需要改变规格。
