If the second information processing device is connected to a communication simulation device (200), a communication simulation unit (260) carries out a communication with the second information processing device by executing the first simulation program. If the first information processing device is connected to the communication simulation device, the communication simulation unit carries out a communication with the first information processing device by executing the second simulation program.

Description

Communication simulation device and communication simulation program

The present invention relates to a technique for simulating communication of one information processing apparatus and communicating with the other information processing apparatus.

A manufacturing apparatus for manufacturing is installed in the factory. The main components of the manufacturing apparatus are a machine that performs processing and assembly, a sensor that detects the state of the manufacturing apparatus and the surrounding environment, and a programmable logic controller (PLC) that controls the machine and the sensor.
A method of controlling machines and sensors is designed to produce an object, a control program based on the design is written into the PLC, and the PLC operates.

Information held by the manufacturing apparatus, such as operating status and manufacturing results, is reflected in an information system such as supply chain management or corporate resource management. As the mechanism, a manufacturing execution system (MES) is used.
The MES receives an information collection instruction from the information system, acquires information from the manufacturing apparatus, and stores the acquired information so that it can be used from the information system.
For this reason, communication for reading and writing data is performed between the manufacturing apparatus and the MES.

When a factory is built, typically the manufacturing equipment and MES are developed in parallel by separate developers.
When the development of each of the manufacturing apparatus and the MES is completed, a combination test between the developed actual machines is performed. At the stage of this combination test, a communication failure between the manufacturing apparatus and the MES is detected.
When a communication failure is detected, it is analyzed whether the cause of the failure is the manufacturing apparatus or the MES. And correction work is performed about the cause of a malfunction.
In order to prevent the occurrence of such trouble analysis and rework, verification related to communication is performed in the development process of each of the manufacturing apparatus and the MES.
However, since there is no actual machine as a communication partner in the development process, how to perform verification related to communication becomes a problem.

Patent Document 1 includes the same number of virtual devices as the actual devices constituting the production system, connects the actual devices and the virtual devices according to the connection relationship set by the setting unit, and synchronizes the actual devices and the virtual devices. A technique for executing simulation is disclosed. With this technology, even when there is no real machine, it is possible to perform verification related to communication by replacing the real machine with a virtual device.
However, the virtual device does not necessarily perform the same operation as the actual device. Therefore, even if communication can be performed correctly by verification using a virtual device, a problem may occur in communication between real machines.
The reason why the virtual device does not perform the same operation as that of the actual machine is a case where a discrepancy in communication specifications occurs between the developer of the manufacturing apparatus and the developer of the MES. In the process of separately developing the manufacturing apparatus and the MES, if a change in specifications related to communication such as a communication procedure or interface definition occurs, there is a possibility that the specification change is not reflected in each development of the manufacturing apparatus and the MES. . Then, due to the omission of reflection of the specification change, there is a discrepancy between the developer of the manufacturing apparatus and the MES developer regarding the interpretation of the communication specification. As a result, the virtual device of the MES prepared for verification by the developer of the manufacturing apparatus and the virtual device of the manufacturing apparatus prepared for verification by the developer of the MES will operate differently from the actual machine. . Even if there is no interpretation error related to the communication specification, if the virtual device is misconfigured, the virtual device still operates differently from the actual device.
If the virtual device performs an operation different from that of the actual device, a communication failure that is not detected in the verification using the virtual device occurs in the combination test using the actual device of the manufacturing apparatus and the MES.

The processing table of FIG. 5 includes three communication processes of reading (1), writing (2), and writing (3).
Read (1) includes two events, the start of reading and the end of reading, and Write (2) (3) includes two events, the start of writing and the end of writing.
Therefore, the communication model generation unit 220 starts reading (1), ends reading (1), starts writing (2), ends writing (2), starts writing (3), and writes. Six events with the end of (3) are extracted.

In S132h, the communication model generation unit 220 generates a processing object 292O for each extracted event, and assigns an object name to the generated processing object 292O.

In S133h, the communication model generation unit 220 selects one unselected event in order.
As shown in the timing chart of FIG. 5, the six events are: start of write (2), start of write (3), start of read (1), end of read (1), end of write (2), Occurs in the order of completion of writing (3).
Therefore, the communication model generation unit 220 starts writing (2), starts writing (3), starts reading (1), ends reading (1), ends writing (2), and ends writing (3). In this order, one unselected event is selected.
Then, the communication model generation unit 220 sets a number indicating the order of the selected event in the processing object 292O of the selected event.

In S134h, the communication model generation unit 220 extracts the processing subject of the selected event from the procedure data 291C.
The processing table of FIG. 5 includes processing subjects for each processing. Therefore, the communication model generation unit 220 extracts the processing subject of the processing corresponding to the selected event from the processing table.
Then, the communication model generation unit 220 sets the extracted processing subject to the selected processing object 292O.

In S135h, the communication model generation unit 220 extracts the processing conditions of the selected event from the procedure data 291C.

Therefore, the communication model generation unit 220 extracts a condition for determining that the previous event has ended as a processing condition. If the selected event is the first event, there is no processing condition to be extracted.
Then, the communication model generation unit 220 sets the extracted processing condition in the processing object 292O of the selected event. However, when the selected event is the first event, it is not necessary to set processing conditions.

In S136h, the communication model generation unit 220 extracts the processing content of the selected event from the procedure data 291C.
The extracted processing content is the content excluding the processing subject and processing conditions.

In S133s, the communication model generation unit 220 selects one unselected message in order.
As shown in the sequence diagram of FIG. 6, four messages are generated in the order of read (1), write (2), write (3), and write (4).
Therefore, the communication model generation unit 220 selects one unselected message in the order of reading (1), writing (2), writing (3), and writing (4).
Then, the communication model generation unit 220 sets a number indicating the order of the selected message in the processing object 292O of the selected message.

In S134s, the communication model generation unit 220 extracts the processing subject of the selected message from the procedure data 291C.
The sequence diagram of FIG. 6 includes a processing entity for each message. The subject on the starting point side of the arrow representing the message is the processing subject. For example, the processing subject of the reading (1) is the first information processing apparatus 110A represented by “first”.
Then, the communication model generation unit 220 sets the extracted processing subject to the selected processing object 292O.

In S135s-1, the communication model generation unit 220 extracts the processing conditions of the selected message from the procedure data 291C.
The selected message occurs after communication of the previous message is completed. Therefore, the communication model generation unit 220 extracts a condition for determining that the communication of the previous message has ended as a processing condition. If the selected message is the first event, there is no processing condition to be extracted.
Then, the communication model generation unit 220 sets the extracted processing condition in the processing object 292O of the selected message. However, when the selected message is the first message, it is not necessary to set processing conditions.

In S135s-2, the communication model generation unit 220 determines whether the selected message is the first message in the combined fragment.
When the selected message is the first message in the combined fragment, the communication model generation unit 220 extracts the conditional expression included in the combined fragment as a processing condition.
The sequence of FIG. 6 includes a binding fragment marked with “opt”. The first message in this combined fragment is a write (2). Therefore, when the selected message is write (2), the communication model generation unit 220 extracts a conditional expression included in [Conditional Expression] written in the combined fragment as a processing condition.
Then, the communication model generation unit 220 adds the extracted processing condition to the processing object 292O of the selected message.

In S136s, the communication model generation unit 220 extracts the processing content of the selected message from the procedure data 291C.
The extracted processing content is the content excluding the processing subject and processing conditions. The processing table of FIG. 6 includes a type, a target address, a write value, and a storage address. Therefore, the communication model generation unit 220 extracts the type, target address, write value, and storage address corresponding to the selected message as processing contents from the processing table.
Then, the communication model generation unit 220 sets the extracted processing content in the processing object 292O of the selected message.

In S137s, the communication model generation unit 220 determines whether there is a next message.
If there is a next message, the process proceeds to S138s.
If there is no next message, the communication model generation process (S130) ends.

In S138s, the communication model generation unit 220 sets the object name of the processing object 292O of the next message as the next object name in the processing object 292O of the selected message.
After S138s, the process returns to S133s.
