Abstract: An industrial control system device that can be utilized for drive control, process control and/or logic control and which is comprised of a unique combination of hardware and software. Use of one or more of the devices in an industrial control system application permits the control system to be partitioned into subsystems which communicate with one another and which operate as self-contained units. Each subsystem can be further subdivided into modules that have distinct operating functions. The software utilized by the control system device separates the required operating functions of the control system into distinct tasks that operate concurrently (multi-tasking) on a priority level basis while sharing system data and control signals. Three programming languages (BASIC, Control Block, Ladder Logic) are employed so that the most appropriate language can be utilized for each task. Processors can be added to the industrial control system to permit the movement of a task from processor to processor (multi-processing) without reprogramming.

Abstract: A controller stores link information linking a predetermined event to a variable associated with the event. The controller stores first log information in association with time information into a memory in response to occurrence of the predetermined event. The first log information includes information about the event, and a current value of a predetermined variable associated with the event included in the link information. The controller stores second log information in association with time information into a memory in accordance with a predetermined period. The second log information includes information about a value of the predetermined variable. An information processing device obtains the link information from the controller, and displays information indicating the variable associated with an event indicated by the first log information onto the monitor-based on the link information and the second log information.

Abstract: A digital computer implemented software system is provided for programming industrial logic controllers using a software package of the type utilizing relay ladder logic to represent control programs. The control program is executable by the controller to control the operation of one or more industrial devices. Using relay ladder logic, the control programmer is provided with a system to replace a coil with an ACTION block containing at least one complex expression. When the left side of the ACTION block is energized, the expression is evaluated. In a further embodiment, the programmer is able to replace a contact with a DECISION block containing a Boolean expression. When the left side of the DECISION block is energized, the Boolean expression is evaluated. If the expression evaluates as TRUE, the right side of the DECISION is energized.

Abstract: 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.

Abstract: A program fragmentation unit (131) divides a target program into fragments according to groups of processing. A fragment group extraction unit (132) extracts, from among sets of fragments, each set in which instruction groups match between fragments, as a fragment group. A functionalization candidate extraction unit (136) extracts, from among sets of fragment groups, a set in which instruction groups match between fragment groups, usage patterns of a variable group match between the fragment groups, and types of variables match between the fragment groups, as a functionalization candidate. An output unit (140) outputs information on the functionalization candidate.

Abstract: A system and method for controlling operation of a plurality of elements in an automated process, such as a production process, and indicating error conditions as they occur. Each unique set of input and output conditions of the various system elements defines a unique logic state or zone. Thus, there are defined a multiplicity of valid system logic states or zones, each having a unique input/output image. A predetermined sequence of zones, productive zones representing designed machine operations, is stored in a zone table. All zones not explicitly defined in the zone table are automatically treated as error zones. A zone engine automatically cycles to observe any change in input/output image. Any change in inputs from the various system elements automatically transfer action to the unique zone associated with such inputs, resulting in corresponding changes in control outputs to the system elements and/or display an error message as appropriate.

Abstract: A computer-implemented system and method for configuring a plurality of field devices enables a user to perform both device parameter editing and marking device parameters for bulk transfer in a simple an easy manner. The system and method provide a single application or utility that enables a user to view and make configuration changes as well as to view and change bulk transfer status for individual field device parameters while providing the user contextual information regarding the field device components to which the field device parameters belong or relate. The system and method provide the user with typical or standard configuration screens that enable the user to perform configuration activities in a simple and well-known format, but that include contextual indications of the various field device components to which the displayed field device parameters relate. This functionality enables the user to view and change the bulk transfer status of the individual parameters, without needing to go to a separate application or screen.
