    摘要: An address associated with a failure in a programmable controller is provided, for reading out an operating state of each element of a sequence circuit. The address and a logic level thereof are stored in an address setting table (TA). The logic level is compared with a logic level of an actual signal stored in a signal update storage table (TB), and a difference therebetween is detected by a signal update detecting means (2). Every time a difference is detected, a signal update writing means (3) writes the address and the logic level of the actual signal into the signal update storage table (TB). The storage contents of the signal update storage table (TB) are displayed on a display means, thereby allowing an operator to check for the cause of the failure.

    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: 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.

    摘要: Not any special display is required to provide a monitor displaying of I/O data and timer/counter data during operation of programmable controller. Instead, the display of program console will be utilized to display instruction codes and addresses or error messages in characters. Multiple number of sets, in which the numbers of either I/O data or timer/counter data which optionally specified with numbers, are displayed simultaneously on the character display of the program console.
