Description

  The present invention relates to drawing software.

  The programmable display is usually connected to a PLC (Programmable Logic Controller), and is used to display and operate the state of the device itself and the connected PLC. Project data for PLC status display and operation is created using a project data creation device, which is a computer installed with drawing software, and is transferred from the project data creation device to a programmable display.

  In many cases, after programming the PLC, in order to create a display screen by drawing software, list the devices used in the PLC with comments, and refer to them to assign devices on the drawing software. It is common to do. The device is a memory address of the PLC associated with a specific function provided in the PLC or a device connected to the PLC, and the value of the memory address specified by the device by describing the device in the PLC control program. By rewriting, the function assigned to the device is executed, or the device assigned to the device is controlled. Hereinafter, a device to which a comment is added is referred to as a device comment.

  In order to improve the efficiency of creating the display screen, it is possible to understand the role of the device by referring to the comments assigned in advance in the PLC programming software when inputting the device. It is a conventional method to improve.

  Or, when a device is labeled by arbitrarily setting a label for each device, it is possible to centrally manage the allocation of labels and devices, etc., and use the label without being aware of the device The conventional technique is to improve the drawing efficiency. A label is a variable associated with a memory address. By creating a control program using such a variable instead of a device, the assignment between the variable and the memory address can be changed to change the control. When a new control program is created by combining programs, it is possible to eliminate inconsistencies in address assignment.

  In Patent Document 1, variable allocation information is read from a PLC, address unresolved screen data using a variable that is not associated with a memory address in the PLC is used as an address resolution screen based on the variable allocation information read from the PLC. A display device for converting data is disclosed.

  To design a display screen using drawing software from a list of device and comment combinations or labels used in an external device such as a PLC, refer to the display method on a programmable display for device comments and labels. It is necessary to perform the work of designating manually, which takes time. Note that specifying the display method of devices and comments on a programmable display is called object type assignment. Performing manual assignment of object types can cause human errors such as device errors.

  In the conventional method, device comments and labels can be referred to at the time of device setting. However, in creating a screen, after setting an object once, it is necessary to select and set a device or label to be used from a device comment or label list on the setting screen. In addition, device comments and labels include those that do not need to be set as objects on the screen, so depending on the data, the number of devices and labels in the list is enormous. It takes a lot of time to create the screen.

  The display device disclosed in Patent Document 1 makes it possible to assign a memory address to a variable that has not been assigned a memory address without communicating with a screen data creation device. There is no disclosure of a method for assigning object types to completed variables in a batch.

  The present invention has been made in view of the above, and collectively assigns object types to device comments and labels used in a control program for PLC, and lists object assigned device comments or object assigned labels. The object image representing the device comment selected from the object assigned device comment displayed and listed or the label selected from the object assigned label is added to the project data being created on the editor screen for creating project data The purpose is to obtain drawing software.

  In order to solve the above-described problems and achieve the object, the present invention provides a project data creation device having an editor screen for creating project data for causing a programmable display to perform status display and control of a programmable logic controller. Drawing software that allows a computer to function, from a program creation software that creates a control program for a programmable logic controller to a device that is used in the control program to specify a memory address in the programmable logic controller Get at least one of the label used in the control program to indirectly specify the memory address that is a variable associated with the device comment and memory address with Means, batch assignment means for batch assigning an object type representing a display method on a programmable display to the acquired device comments and labels, list display means for displaying a list of object assigned device comments or object assigned labels, An object that adds an object image that represents an object assigned device comment selected from the object assigned device comments displayed in a list or an object assigned label selected from an object assigned label to the project data being created on the editor screen It is characterized by functioning as additional means.
