Abstract
In a programmable controller system, a program display device includes: a command name conversion table; a second conversion unit that receives a program list from a programmable controller and converts a command number described in the program list into a command name on the basis of a command name conversion table; a non-corresponding command name acquisition unit that acquires a command name corresponding to a non-corresponding command number among the command numbers described in the program list on the basis of an additional command information table; and a display unit that displays the command name converted by the second conversion unit and the command name acquired by the non-corresponding command name acquisition unit.
Claims17
A programmable controller system comprising:
- a programmable controller;
- and
- a program display device that is communicably connected to the programmable controller,
- wherein the programmable controller includes:
- a program that is described using a command number for uniquely identifying a command to control an external device;
- an additional command information table that defines association between a command name, which is a name corresponding to the command number, and the command number and defines association between a non-corresponding command number which is not present in a command name conversion table included in the program display device and a command name corresponding to the non-corresponding command number;
- and
- a first conversion unit that converts the non-corresponding command number into the command name on the basis of the additional command information table, and
- the program display device includes:
- the command name conversion table;
- a second conversion unit that receives the program from the programmable controller and converts the command number described in the program into the command name on the basis of the command name conversion table;
- a non-corresponding command name acquisition unit that acquires the command name corresponding to the non-corresponding command number among the command numbers described in the program on the basis of the additional command information table;
- and
- a display unit that displays the command name converted by the second conversion unit and the command name acquired by the non-corresponding command name acquisition unit.
A program display device that is communicably connected to a programmable controller, which has a program that is described using a command number for uniquely identifying a command to control an external device, to form a programmable controller system, comprising:
- a command name conversion table that defines association between a command name, which is a name corresponding to the command number, and the command number;
- a conversion unit that receives the program from the programmable controller and converts the command number described in the program into the command name on the basis of the command name conversion table;
- a non-corresponding command name acquisition unit that acquires a command name corresponding to a non-corresponding command number which is not present in the command name conversion table among the command numbers described in the program, on the basis of additional command information table, included in the programmable controller, that defines association between the non-corresponding command number which is not present in the command name conversion table and the command name corresponding to the non-corresponding command number;
- and
- a display unit that displays the command name converted by the conversion unit and the command name acquired by the non-corresponding command name acquisition unit.
A programmable controller that has a program, which is described using a command number for uniquely identifying a command to control an external device, and is communicably connected to a program display device to form a programmable controller system, comprising:
- an additional command information table that defines association between a command name, which is a name corresponding to the command number, and the command number and defines association between a non-corresponding command number which is not present in a command name conversion table included in the program display device and a command name corresponding to the non-corresponding command number;
- and
- a conversion unit that converts the non-corresponding command number into the command name, on the basis of the additional command information table, in response to a request from the program display device and transmits the command name to the program display device.
A program display method that displays a program, which is described using a command number for uniquely identifying a command to control an external device, on a program display device, comprising:
- converting the command number described in the program into a command name, which is a name corresponding to the command number, on the basis of a command name conversion table, included in the program display device, that defines association between the command name and the command number;
- acquiring a command name corresponding to a non-corresponding command number which is not present in the command name conversion table among the command numbers described in the program, on the basis of additional command information table, included in a programmable controller, that defines association between the non-corresponding command number which is not present in the command name conversion table and the command name corresponding to the non-corresponding command number;
- and
- displaying the command name converted in the converting and the command name acquired in the acquiring.
