Abstract: An industrial controller executing a graphical language employs a comparator circuit for monitoring the address locations of memory used to store the control program and its data. A cursor positioned on a graphics representation of the program is used to identify a particular graphical element to be monitored and the address of the starting instruction for that element is loaded into the comparator. An interrupt generated by the comparator causes the generation of a histogram listing the particular rungs name and the times at which it has been executed, useful for verifying and monitoring the operation of a control program. A snapshot of data values used by the element of the program at the time of its execution may also be stored to verify the condition under which the element executes.

A screen of a display unit displays a stitch structure including a type of thread for each stitch of a knit fabric. The display area of each stitch is divided into a ground yarn display area and a plating yarn display area based on the type of stitch. The ground yarn is allocated to one of the divided areas while the plating yarn is allocated to the other of the divided areas.

Abstract: A method, system and program for creating child graphical objects in an object oriented graphical user interface. First, the child object is created by copying a set of attributes from a parent graphical object to a memory partition allocated to the first child graphical object. This operation is typically called inheritance or subclassing in object oriented programming. Next, the location data of the first child graphical object is automatically changed from those copied from the parent graphical object. Next, the parent and child graphical objects are displayed on a display in the graphical user interface, the child graphical object being offset in location from the parent graphical object.

Abstract: A method and an apparatus for writing display data to and reading display data from a FIFO. In one embodiment of the present invention, a memory controller coupled to a memory is configured to retrieve display data from the memory and write the retrieved data to a FIFO. The memory controller retrieves the display data from the memory in response to a FIFO write signal received from an output display controller. The output display controller is further configured to generate a FIFO read signal which is received by the FIFO. In response to the FIFO read signal, display data entries are sequentially read from the FIFO and transferred to an output display. The present invention features a programmable memory circuit such as a register, configured to store the value pointing to a particular display data entry in the FIFO. When the particular display data entry is read, a subsequent FIFO write signal is issued to the memory controller.

Abstract: A scanning signal from a scanning electrode drive circuit and a data signal from a signal electrode drive circuit are applied to a liquid crystal panel to perform image display in the liquid crystal panel. Here, as well as power supply to the scanning electrode drive circuit and the signal electrode drive circuit being from separate power supply circuits, a voltage for producing a data signal in the liquid crystal drive voltage power supply circuit is generated with a central voltage of a liquid crystal drive voltage power supply circuit, which is for generating a voltage for producing the scanning signal, as a reference voltage. Because power is supplied separately to the scanning electrode drive circuit and the signal electrode drive circuit, the breakdown voltage of the signal electrode drive circuit is alleviated and thus power consumption is reduced, and further, flickering does not occur in the display, etc., even if there are fluctuations in the power supply voltage.
