2. Description of the Related Art Generally, various control devices that an operator can operate include a display means for displaying the status of equipment to be operated, and an operation means for an operator to input a command.
The control unit actually operates the operation target device. The display means and the operating means with which the operator contacts are usually integrated. Further, when operating manufacturing equipment or the like in a factory, a programmable controller or the like is often used as the control unit.

Since there is a demand for the display means to display various information such as internal information of the control section and programs in addition to the information necessary for operating the operation target device, the display content is rich. The amount of information also increases, and it often becomes large and heavy. There are also positional restrictions due to the length of the cable connected to the power supply. As a result, the display operation unit is installed and used in a fixed place. Then, the operator in the manufacturing factory or the like inputs a desired operation command for the operation target device while viewing the operation target device and the display information displayed on the display means.

[0004]

[Problems to be Solved] However, in the case of the display operation panel of the above method, when the remote operation target device or the back side of the operation target device is closely observed and controlled, the operator is close to the operation target device. There are some inconveniences, such as going back to the operation after checking up and going back to operate the device, or arranging another person near the device to be operated and operating in coordination. The present invention
The present invention has been made in view of such conventional problems, and relates to a display operation panel excellent in operability that allows an operator to freely operate away from the apparatus body.

[0005]

A display operation panel according to the invention of claim 1 of the present application includes a controller provided with an input / output unit and a main unit.
It has a display / operation unit, a simple / display operation unit, and operation unit selection means for switching the display / operation unit to either the main / display operation unit or the simple / display operation unit. And
A relatively low speed and high signal between the controller and the simple / display operation unit via a wireless connection by electromagnetic waves reaching the periphery of the operation target device or a wire of a length that can approach the vicinity of the operation target device. Wired by level electric signal.

Therefore, it is possible to move the simple / display operation unit to the vicinity of the operation target device and use it while maintaining the connection state with the controller. Therefore, according to the display / operation panel of the present invention, the operator can carry out the operation while moving away from the apparatus main body to the vicinity of the operation target device while carrying the simple / display operation unit.

[0007] Further, the display operation unit, which is the main body of the operation by the operation unit selection means, that is, the display operation unit to which the controller responds and issues an operation command to the operation target device is a simple / display operation unit or a main / display unit. It can be switched to either one of the operation units. Therefore, there is no risk that a double operation command will be issued from the two display operation units. The display / operation panel may be, for example, a display / operation panel for a programmable controller as described in claim 2.

The operating section selecting means may be the same as in claim 3.
As described, it is preferable to provide the simple / display operation unit. Because the operator may operate the simple / display operation unit in the vicinity of the operation target device, it is preferable to secure the display / operation unit, which is the main operator, from the viewpoint of safety. The reason is that it is not preferable to switch the display operation unit, which is the main body of operation, to the main / display operation unit. That is, when the operator is near the operation target device, it is appropriate to lock the command from the main / display operation unit from the viewpoint of safety for the operator.
