Abstract

PURPOSE:To display an alarm generation/restoration time which has been generated in the past in a display device at an optional time by means of a real time system by inputting a counter value by means of an interval timer part in a controller. CONSTITUTION:When the display indication of an operator is inputted in a display/selection indicating part 6 in the display device 200, it is informed to a display data reception part 7, and an input request is informed to a display data transmission part 5 in the controller. The display data transmission part 5 transmits alarm hysteresis data of an alarm hysteresis file 4 and a present counter value to the display data reception part 7 of the display device. Reception data is informed to a real time operation part 8, and a real time at the alarm generation/restoration time is calculated by using the real time 9. A display date editing part 10 edits the calculated real time and alarm information and alarm hysteresis data is displayed in a display part 11. Thus, the alarm generation time can easily be learnt.

Conventionally, the alarm generation time display method in this type of real-time operation control device has been a method in which each control device has a real-time display function and the display time is adjusted and used, or There is an interval time because there is no real time display function within the unit. It was either a counter value display or a relative time display method. [Problems to be Solved by the Invention] In the conventional control device having a real-time display function as described above, it is necessary to input the real time in advance for each control device, especially when there are many control devices in the same system. When performing distributed processing, it is difficult to synchronize the time of all control devices. Furthermore, when real-time calculations and storage are performed within the control device, the processing execution time and real-time storage memory become large, which has the disadvantage of placing a load on the control processing function of the control device. Furthermore, control devices that do not have a real-time display function have the disadvantage that the alarm generation time cannot be easily determined. [Means for solving the problem] The alarm occurrence time display method of the present invention is as follows. By storing the counter value by the interval timer section in the control device in order at the time of alarm occurrence/recovery, and transmitting the alarm occurrence/recovery counter value and the current counter value to the display device when a display data input request is received from the display device. It has the function of performing the following arithmetic processing within the display device and displaying the alarm occurrence/recovery time in real-time display format. A
=N- (Go -Cl) where A is the alarm occurrence real time, N is the current real time, and C
O is the current counter value, and C1 is the counter value when an alarm occurs.

FIG. 1 is a functional block diagram of an embodiment of the present invention. An alarm detection section 1 in the control device 100 detects occurrence/recovery of an alarm based on data handled within the device, and notifies the alarm history editing section 2 of the alarm information. The alarm history editing section 2 receives the current counter value from the interval timer section 3, adds it to the alarm information, and stores it in the alarm history file 4.

The interval timer counter value is in 4-byte format and counts up by 1 at 1 second intervals. If cleared when the control device is started up, it can be counted for approximately 136 years. The value obtained by subtracting the count value at the time of alarm occurrence from the current count value indicates how many seconds ago the alarm occurred from now.
Subtracting this value from the real time becomes the real time when the alarm occurs. [Effects of the Invention] As explained above, the present invention allows alarm generation/recognition that occurred in the past at any time in the display device by inputting the counter value from the interval timer section in the control device.
This has the effect of displaying the recovery time in real time format.
