Abstract

An objective of the present invention is to simplify generation of a program for carrying out data collection performed by a PLC and reduce the burden on an operator. The invention comprises: a device information library (111) which stores program templates corresponding to various process relating to data collection and, for each target device from which data is to be collected, device parameters corresponding to said target device; and a program generation unit (117) which generates a data collection program using program templates and device parameters corresponding to an accepted target device.

First claim

1 . A program generation device, which generates a data collection program enabling a programmable logic controller (PLC) to execute processing related to data collection, the program generation device comprising:
a storage portion which stores program templates corresponding to plural processing related to the data collection and stores, for each target apparatus from which data is to be collected, apparatus parameters corresponding to the target apparatus; a reception portion which receives input of the target apparatus from a user; and a program generation portion which generates a data collection program for collecting data from the target apparatus by the PLC by using the program templates and the apparatus parameters corresponding to the target apparatus received by the reception portion.

2 . The program generation device according to claim 1 , wherein
an incorporation column for incorporating the apparatus parameters or processing corresponding to the apparatus parameters is arranged in the program template, and the program generation portion generates the data collection program by incorporating the apparatus parameters or processing corresponding to the apparatus parameters into the incorporation column of the program template.

3 . The program generation device according to claim 1 , wherein
the program generation portion generates the data collection program comprising a program for controlling communication for acquiring data from the target apparatus.

4 . The program generation device according to claim 1 , which
acquires information of a relay device connected to the PLC from the PLC, and displays apparatuses capable of being connected to the relay device on a display portion as selection candidates of the target apparatus.

5 . The program generation device according to claim 4 , which
displays a numerical input screen which receives input of at least one of a numerical value and a character string related to the apparatus parameters corresponding to the target apparatus selected from the selection candidates.

6 . The program generation device according to claim 1 , wherein
the program generation portion generates a database definition program for defining a database which stores collected data by using the program templates and the apparatus parameters corresponding to the target apparatus received by the reception portion.

7 . The program generation device according to claim 1 , wherein
the reception portion receives a correction instruction for the data collection program generated by the program generation portion.

8 . A control method of a program generation device which generates a data collection program enabling a programmable logic controller (PLC) to execute processing related to data collection, wherein program templates corresponding to plural processing related to the data collection and, for each target apparatus from which data is to be collected, apparatus parameters corresponding to the target apparatus are stored in a storage portion, the control method comprising:
a reception step of receiving input of the target apparatus from a user; and a program generation step of generating a data collection program for collecting data from the target apparatus by the PLC by using the program templates and the apparatus parameters corresponding to the target apparatus received in the reception step.

9 . A non-transitory computer readable recording medium that records a control program for enabling a computer to function as the program generation device according to claim 1 , and enabling the computer to function as the program generation portion.

10 . (canceled)

11 . The program generation device according to claim 2 , wherein
the program generation portion generates the data collection program comprising a program for controlling communication for acquiring data from the target apparatus.

12 . The program generation device according to claim 2 , which
acquires information of a relay device connected to the PLC from the PLC, and displays apparatuses capable of being connected to the relay device on a display portion as selection candidates of the target apparatus.

13 . The program generation device according to claim 3 , which
acquires information of a relay device connected to the PLC from the PLC, and displays apparatuses capable of being connected to the relay device on a display portion as selection candidates of the target apparatus.

14 . The program generation device according to claim 11 , which
acquires information of a relay device connected to the PLC from the PLC, and displays apparatuses capable of being connected to the relay device on a display portion as selection candidates of the target apparatus.

15 . The program generation device according to claim 12 , which
displays a numerical input screen which receives input of at least one of a numerical value and a character string related to the apparatus parameters corresponding to the target apparatus selected from the selection candidates.

16 . The program generation device according to claim 13 , which
displays a numerical input screen which receives input of at least one of a numerical value and a character string related to the apparatus parameters corresponding to the target apparatus selected from the selection candidates.

17 . The program generation device according to claim 14 , which
displays a numerical input screen which receives input of at least one of a numerical value and a character string related to the apparatus parameters corresponding to the target apparatus selected from the selection candidates.

18 . The program generation device according to claim 2 , wherein
the program generation portion generates a database definition program for defining a database which stores collected data by using the program templates and the apparatus parameters corresponding to the target apparatus received by the reception portion.

19 . The program generation device according to claim 3 , wherein
the program generation portion generates a database definition program for defining a database which stores collected data by using the program templates and the apparatus parameters corresponding to the target apparatus received by the reception portion.

20 . The program generation device according to claim 4 , wherein
the program generation portion generates a database definition program for defining a database which stores collected data by using the program templates and the apparatus parameters corresponding to the target apparatus received by the reception portion.
