Abstract

PURPOSE:To make a selection operating device compact, and to improve the operability by selecting and displaying a state of only a selected equipment. CONSTITUTION:This selection operating device is constituted of a monitor panel 1 for displaying an operating state of a plant 8, an operating board 5, and a programmable controller 4 for displaying a plant state on a symbol state indicator 2 and outputting signal to an apparatus which is selected by an apparatus selecting switch 6, by a master operating switch 7, etc. In such a case, in the operating board 5, a common selection state indicator 9 for displaying the present state of a selected equipment is provided instead of an individual indicator. In such a state, when one o equipment selecting switches 6 is turned on and an equipment is selected, a fact that the equipment is being selected is displayed by turning on its corresponding switch 6, and simultaneously, the present state of the selected equipment is displayed on the selection state indicator 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention 1] The present invention relates to a selection operation device for selecting and operating an arbitrary device from a large number of operation targets.

[Technical dorsal fin of the invention and its problems 1 An example of a conventional selection operation device is shown in FIG.

In Fig. 3, 1 is a monitoring panel that displays the operating status of the plant, 2 is a graphic symbol display of the monitoring panel 1, and 3
4 is a display that displays the individual status of each device, and 4 is a display that displays the plant status on the symbol status display 2 and individual status display 3, or is selected according to a signal from the equipment selection switch 6 on the operation board 5. It is programmable to notify the operator of the selected device by flickering the symbol status display 2 of the selected device, or to output an operation signal to the device selected by the device selection switch 6 in response to a signal from the mask operation switch 7. A controller 8 is a plant including the above-mentioned devices.

The conventional selection operation device requires a large space because all devices other than the selected 8i device are displayed at the same time. That is, there are usually nearly 10 display items per device. For example, when there are 10 devices, the individual status display 3 requires a display section with 10 points x 10 points, or 100 points. In addition, the operator can check the status of the selected device on the individual display 3, which constantly displays the status of all devices.
There is a problem that the operation becomes troublesome because it is necessary to search among the .

[Object of the Invention] An object of the present invention is to provide a rational selection operation device that is compact and has improved operability by selectively displaying the status of only the selected device.

[Summary of the Invention] The present invention provides a selection operation device that selectively operates a plurality of devices in a plant via a programmable controller and displays the status of the devices. This selection operation device is equipped with a shared selection status display in the equipment, thereby making the status display compact and easy to read by the operator.

[Embodiments of the invention] An embodiment of the present invention is shown in FIG.

In FIG. 1, the conventional individual display 3 in FIG.
Instead, a shared selection status display 9 is provided in the selection operation board 5 for displaying the current status of the selected device. The selection status display 9 has a number of points (for example, 10 points) that can display all display items for one selected device.
It suffices to have . The rest is the same as the conventional figure 3.

Next, the operation shown in FIG. 1 will be explained with reference to the flowchart shown in FIG.

In FIG. 1, when one of the selection operation switches 6 is turned on and a device to be operated is selected from within the plant, the corresponding selection operation switch lights up to indicate that the device is being selected. At the same time, the current status of the selected device is displayed on the selection status display 9.

The status display includes automatic 9 manual mode status, driving,
This includes the status of equipment being stopped. For example, if the mode state of the selected device is automatic, it cannot be operated as it is, so first turn on the manual mode of the mask operation switch 7.

As a result, the mode is switched to manual mode, and manual mode is displayed on the selection status display 9.

Assuming that the selected device is in a stopped state, when the operation of the mask operation switch 7 is turned on, an operation signal is output from the programmable controller 4 to the selected device, and the corresponding device is operated and its state is selected. It is displayed on the status display 9. After a certain period of time has elapsed after the mask operation, the selection is automatically canceled and the selected surface water of the selection operation switch 6 and the display of the selection state display 9 are turned off.

[Effects of the Invention] As explained above, according to the present invention, the device status is displayed only for the selected device, so the display is compact and easy to distinguish, thus facilitating easy-to-understand selection operations and operation. It becomes possible to perform operation and monitoring operations.
