    摘要： A task executed on a multi-tasking industrial controller is employed to monitor data exchanged between a control program (executed as a second task on the industrial controller) and the controlled process. The monitoring task, which may be invoked on a periodic basis, reads designated data, compares it to its last value and if it changes, stores the value in a buffer. A separate program reads this buffer and displays relevant information to the user minimizing degradation in the performance of the control program and eliminating the possibility of corruption of the control program as would be required for the introduction of special memory trapping instructions into the control program.

    摘要： A method of editing a real-time control program as it controls equipment is provided in which the editing occurs in a second area of memory and integrated into the pre-existing program by means of conditional jump instructions concatenated to that edited material. The pre-existing program is uninterrupted by the editing process except for a change of single instructions which do not affect the results of the execution but redirect the execution thread of that control program to be conditionally connected to the edited material. This single writing of single instructions, which do not affect execution results, precludes the possibility of the controller executing partially edited programs. The jump instructions are conditional on a test edit pointer to allow instantaneous implementation of the edits and a simple return to unedited instructions simply by changing the state of the flag.

    摘要： The present invention relates to a system and methodology to mitigate memory current requirements in an industrial controller and to facilitate efficient on-line editing, storage and retrieval of user programs and data. A segmented memory architecture is provided, wherein a first memory segment is loaded with programmed instructions and other data that is relatively static in nature. A second memory segment is provided for storage of dynamic information such as controller data table variables that change frequently and/or rapidly during program execution of the controller. An execution memory is concurrently loaded with the user program to facilitate high performance program execution and to enable on-line edits of the user program during operation of the controller.
