Abstract

PURPOSE: To reduce the man-hour of an operation confirmation test. CONSTITUTION: An automatic facility emulator 1 connected to a facility controller 4 with a communication channel, a procedure file 2 in which the order of processing desired to perform a test and error display when abnormality occurs, etc., are described, and a display 3 on which the content of an error when test abnormality occurs is displayed are used in the operation confirmation test for the facility controller 4 which performs the control of manufacturing facility. The automatic facility emulator 1 reads in the procedure file 2 sequentially, and automatically transmits a signal to the facility controller 4 in such order. The facility controller 4 performs every kind of processing setting a received signal as a trigger, and transmits a signal to the automatic facility emulator 1 again when the processing is completed. At this time, when no signal from the facility controller 4 is received, or a signal different from the one described in the procedure file 2 is received, etc., the content of the error is displayed on the display 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION
_{The present invention relates to an automatic equipment emulator, and more particularly, to an automatic equipment emulator that performs} an operation confirmation test _of an equipment controller that controls equipment on a production line of electronic devices and electronic components.

[0002]

[Prior art]
Conventional equipment _{emulator performs an operation confirmation test equipment controller,} have a function of being connected via a communication line to the installation controller, a signal which is determined for each test pattern generated, confirms a signal sent from the facility controller However, a person combined and repeated each test pattern and input it to the equipment emulator. In addition, a _{technique for} automatically generating all of the large number of test patterns is disclosed _in Japanese Patent Laid-Open No. 05-073353.
_{It is shown in the publication} .

[0003]

In the operation confirmation test _{of the} equipment controller by the conventional equipment emulator described above _,
Requires a person to instruct the equipment emulator for each test pattern one by one, which requires a great number of man-hours for the operation confirmation test. In addition, it is difficult to perform a repeated test for a long time or a test that requires simultaneity in the instruction timing of a test pattern, because the test cannot be performed unless a person gives instructions at any time.

[0004]

Means for Solving the Problems] equipment automatic emulator of the present invention, when performing the operation confirmation test of the installation controller for controlling the manufacturing equipment using equipment emulator signal generated by _the equipment emulator, and using the procedure file that previously described combinations of test patterns consisting of check processing of the signal from the equipment controller to the signal, automatically Loading sends sequential signals to _said equipment Kontora the procedure file, the signal from _the equipment controller It is characterized by displaying items to be checked against.

【Example】
_{Next, the present invention will be described with reference to the drawings.}

FIG _{. 1} is a system configuration diagram showing an embodiment of the present invention. _{This embodiment} comprises an automatic equipment emulator 1, a procedure file 2, a display 3, an equipment controller 4, a work record file 5, and a lot management file 6.

FIG _{. 2 shows} the description contents _{of the} procedure file _{2 in FIG.
Are shown, FIG. 3} is a process diagram showing a process when the equipment automatically emulator _{1 in FIG. 1} is operating.

First, the procedure file 2 as shown in FIG.
Describe the processing order and processing at the time of error in. Then the equipment automatically emulator 1s _are started performs the processing shown in FIG. First, the automatic facility emulator 1 transmits a product arrival signal 31 indicating that a product has arrived at the facility to the facility controller 4. The equipment controller 4 transmits a product arrival recognition signal 32 to the equipment automatic emulator 1. The automatic facility emulator 1 searches the procedure file 2, and when receiving the product arrival recognition signal 32 from the facility controller ₄ , transmits the next product name read request signal 33. here,
When the equipment automatic emulator 1 cannot receive the product arrival recognition signal 32 from the equipment controller 4 or receives a different signal even after waiting for a certain period of time, it refers to the procedure file 2 and sends it to the connected display 3. The name of the signal that has not been transmitted or the different signal that has been transmitted and other error information are displayed. Thereafter, when the equipment controller 4 receives the product name reading request signal 33, it performs a product name reading process 34 and transmits a product name reading completion signal 35. When the automatic equipment emulator 1 receives the product name reading completion signal 35, it performs the same error check as described above, and outputs the product name reading request OFF signal 3
Send 6. When the equipment controller ₄ receives the product name read request OFF signal 36, the work result report processing 37
Then _{, the} work record file 5 and the lot management file 6 are updated, and the work record report completion signal 38 is transmitted.

An operation confirmation test is automatically performed until an end command is found in the procedure file or an error occurs. Furthermore, if placed end command to the procedure file, since repeated combinations of test _{patterns specified} in step file from the beginning, can be performed continuously test, also such durability test.

[0010]

_{According to} the present invention, the operator can freely combine the order of the processes to be tested and describe it in the procedure file in advance, and the automatic facility emulator reads the procedure file and automatically performs the operation confirmation test. Therefore, the man-hours for the operation confirmation test can be significantly reduced. Further, by not designating an end command in the procedure file, it is possible to perform a continuous test, an endurance test, etc., and it is possible to execute a plurality of test patterns in parallel in a short time which can be said to be almost simultaneous depending on the test pattern.
