<One Embodiment>
FIG. 1 is a functional block diagram showing a functional configuration example of the control system 1 according to the embodiment.
As shown in FIG. 1, the control system 1 includes an information processing device 100 and a control device 200.

The information processing device 100 and the control device 200 may be connected to each other via a network such as a LAN (Local Area Network). The information processing device 100 and the control device 200 may be directly connected to each other via a connection interface (not shown).

The control device 200 is a numerical control device known to those skilled in the art and controls the operation of a machine tool (not shown). When the machine tool is a robot or the like, the control device 200 may be a robot control device or the like.
The control target of the control device 200 is not limited to machine tools and robots, and can be widely applied to industrial machines in general. Industrial machines include, for example, various machines such as machine tools, industrial robots, service robots, forging machines and injection molding machines.

Further, the control device 200 has the functions of the transmission / reception means 210 and the authentication means 220.
The transmission / reception means 210 communicates with the information processing device 100 via a logical connection with the information processing device 100.
For example, the transmission / reception means 210 may communicate with the information processing device 100 via two logical connections 300 (1) and 300 (2).
Hereinafter, when it is not necessary to distinguish the logical connections 300 (1) and 300 (2) individually, it is also referred to as "logical connection 300".

The authentication means 220 includes, for example, the authentication information of the application to be described later received from the information processing device 100 via the transmission / reception means 210, and the authentication information (permitted user ID and permitted user ID) of the authentication table stored in advance in the storage unit (not shown). Compare with the list of passwords, etc.) to determine whether to authenticate. The authentication means 220 may determine that the authentication means authenticates, for example, when the authentication information that matches the authentication information of the application from the information processing apparatus 100 is in the authentication table. On the other hand, the authentication means 220 may determine that the authentication is rejected when there is no authentication information in the authentication table that matches the authentication information of the application from the information processing device 100. The authentication means 220 may transmit the authentication result to the information processing device 100.

<Information processing device 100>
As shown in FIG. 1, the information processing apparatus 100 according to the present embodiment is a personal computer or the like, and includes an application executing means 110 and a communication relay means 120.
The information processing device 100 includes an arithmetic processing unit (not shown) such as a CPU (Central Processing Unit) in order to realize the operation of the functional block shown in FIG. Further, the information processing device 100 is temporarily used as an auxiliary storage device (not shown) such as a ROM (Read Only Memory) or HDD (Hard Disk Drive) in which various control programs are stored, or an arithmetic processing device for executing the program. It is provided with a main storage device (not shown) such as a RAM (Random Access Memory) for storing data that is specifically required.

Then, in the information processing device 100, the arithmetic processing device reads the OS and application software from the auxiliary storage device, and while deploying the read OS and application software to the main storage device, arithmetic processing based on these OS and application software is performed. Do. The information processing apparatus 100 controls each hardware based on the calculation result. As a result, the processing by the functional block of FIG. 1 is realized. That is, the information processing device 100 can be realized by the cooperation of hardware and software.

The application execution means 110 executes, for example, three applications 111 (1) to 111 (3) that communicate with the control device 200. Each of the applications 111 (1) to 111 (3) is an application including "connection destination information", "connection group number", and "authentication information" in order to communicate with the control device 200 when executed. The information is transmitted to the communication relay means 120 described later.
Here, the "connection destination information" is information for specifying the connection destination control device 200, such as an IP address and a port number. Further, the "connection group number" is information indicating a group including each application 111, and at the same time, when the information processing device 100 and the control device 200 are connected by a plurality of logical connections 300, each of them. It is a number for distinguishing the logical connection 300. Further, the "authentication information" is information including a user ID, a password, and the like indicating that the connection is permitted.

In FIG. 1, the same "connection group number" is set in advance for application 111 (1) and application 111 (2), and it is indicated by a rectangular broken line that they are included in the same group. In other words, application 111 (1) and application 111 (2) and application 111 (3) are set with different "connection group numbers".

Although the application execution means 110 executes the three applications 111 (1) to 111 (3), a plurality of applications other than the three may be executed.
Further, hereinafter, when it is not necessary to individually distinguish the applications 111 (1) to 111 (3), it is also referred to as "application 111".

The communication relay means 120 relays the communication performed by each of the three executed applications 111 with the control device 200.
Here, the communication relay means 120 has the functions of the transmission / reception means 121, the connection ID issuing means 122, the connection information determination means 123, the connection information storage means 124, and the authentication means 125.

The transmission / reception means 121 logically connects to the control device 200 based on the connection information described later, and each of the three applications 111 transmits / receives data to / from the control device 200.
For example, the transmission / reception means 121 connects to the control device 200 based on the connection information by two logical connections 300 (1) and 300 (2), and each of the three applications 111 connects to the control device 200. Send and receive data with.
The data includes a request from the information processing device 100 to the control device 200 (data read request, data write request, operation instruction request, etc.) and a response (result to the request) from the control device 200 to the request. included.

The connection ID issuing means 122 receives application information from each of the three applications 111 executed by the application executing means 110, and issues a connection ID that identifies each of the three applications 111 based on the application information.
As an example, the connection ID issuing means 122 issues the connection ID (1) to the application 111 (1). Further, the connection ID issuing means 122 issues the connection ID (2) to the application 111 (2). Further, the connection ID issuing means 122 issues the connection ID (3) to the application 111 (3).

When the connection ID issuing means 122 issues the connection ID, the connection information determining means 123 uses the "connection destination information" and the "connection group number" of the application 111 to which the connection ID is issued as keys to store the connection information described later. The connection information stored in the means 124 is searched. When the connection information determination means 123 includes the "connection destination information" and "connection group number" of the same key in the connection information, the connection information determines the "connection destination information" and "connection group number" of the same key in the connection information. , Add the connection ID of the application 111 to which the connection ID was issued.
On the other hand, when the connection information determination means 123 does not have the "connection destination information" and "connection group number" of the same key, the "connection destination information" and "connection group number" fields of the application 111 to which the connection ID is issued are displayed. Create in connection information. The connection information determination means 123 stores information such as the connection ID and authentication information of the application 111 to which the connection ID is issued in the created column. The operation of the connection information determining means 123 and the connection information will be described with reference to FIGS. 4 to 6.

The connection information storage means 124 is a RAM or the like, and stores connection information in which application information and connection ID are associated with each application 111.

The authentication means 125 issued the connection ID when the "connection destination information" and the "connection group number" of the same key as the application 111 to which the connection ID was issued by the connection information determination means 123 were included in the connection information. The authentication information of the application information of the application 111 is compared with the authentication information associated with the same key of the connection information. If the authentication information matches, the authentication means 125 authenticates the application 111 to which the connection ID is issued. On the other hand, the authentication means 125 does not authenticate the application 111 to which the connection ID is issued if the authentication information does not match.
That is, when the "connection destination information" and "connection group number" of the same key are included in the connection information, the information processing device 100 authenticates the application without transmitting the authentication information of the application 111 to the control device 200. It can be carried out. As a result, security between the information processing device 100 and the control device 200 can be ensured without increasing unnecessary traffic between the information processing device 100 and the control device 200.

<Setting processing of control system 1>
Next, the operation related to the setting process of the control system 1 according to the present embodiment will be described. In the following, the setting process of the entire control system 1 will be described first, and then the setting process for each of the applications 111 (1) to 111 (3) will be described.

2 and 3 are flowcharts for explaining the setting process of the control system 1.
In step S11, the connection ID issuing means 122 of the information processing apparatus 100 receives application information from the application 111 executed by the application executing means 110.

In step S12, the connection ID issuing means 122 issues a connection ID to the application 111 that received the application information in step S11.

In step S13, the connection information determination means 123 searches for the connection information of the connection information storage means 124 by using the "connection destination information" and the "connection group number" of the application 111 to which the connection ID was issued in step S12 as keys. ..

In step S14, the connection information determination means 123 determines whether or not the connection information includes the "connection destination information" and the "connection group number" of the same key. If there is "connection destination information" and "connection group number" of the same key, the process proceeds to step S21 (FIG. 3). On the other hand, if there is no "connection destination information" and "connection group number" of the same key, the process proceeds to step S15.

In step S15, the transmission / reception means 121 makes a new logical connection (for example, logical connection 300 (1)) with the transmission / reception means 210 of the control device 200, and “authentication” of the application 111 to which the connection ID is issued in step S12. Information "is sent.

In step S31, the authentication means 220 of the control device 200 receives the authentication information of the application transmitted by the information processing device 100 in step S15, and authenticates the received authentication information.

In step S32 of FIG. 3, the authentication means 220 transmits the authentication result to the information processing device 100.

In step S16 of FIG. 3, the transmission / reception means 121 of the information processing device 100 receives the authentication result for step S15 from the control device 200.

In step S17, the transmission / reception means 121 determines whether the authentication is permitted or rejected in the authentication result received in step S16. In the case of authentication permission, the transmission / reception means 121 maintains the new logical connection connected in step S15, and the process proceeds to step S18. On the other hand, in the case of authentication refusal, the transmission / reception means 121 cancels the new logical connection connected in step S15, and the process proceeds to step S20.

In step S18, the connection information determination means 123 stores the application information and the connection ID of the application 111 for which the connection ID was issued in step S12 in the connection information.

In step S19, the communication relay means 120 transmits the authentication result and the connection ID to the application 111 that issued the connection ID in step S12.

In step S20, the communication relay means 120 determines whether or not there is the next application. If there is the next application, the process returns to step S11. If there is no next application, the setting process of the information processing device 100 ends.

In step S21, the authentication means 125 compares the authentication information of the application information of the application 111 whose connection ID was issued in step S12 with the authentication information associated with the same key of the connection information, and determines whether or not they match. Determine. If they match, the process proceeds to step S18. On the other hand, if they do not match, the authentication means 125 does not authenticate the application 111, discards the connection ID issued in step S12, and proceeds to step S20.

<Setting processing for each application 111>
Next, the setting process for each application 111 will be described.

a) In the case of application 111 (1) When the connection ID issuing means 122 receives the application information of application 111 (1) in step S11, the connection ID issuing means 122 issues the connection ID (1) in step S12.
In step S13, the connection information determination means 123 searches for the connection information stored in the connection information storage means 124 by using the "connection destination information" and the "connection group number" of the application information of the application 111 (1) as keys.
In the connection information determination means 123, for example, when the application 111 (1) is the first application, since no data is stored in the connection information, the “connection destination information” of the same key is included in the connection information in step S14. And "connection group number" are not present.

In step S15, the transmission / reception means 121 connects to the transmission / reception means 210 of the control device 200 with a new logical connection 300 (1), and transmits the authentication information of the application 111 (1). The transmission / reception means 121 receives the authentication result from the control device 200 in step S16.
When the authentication is permitted in step S17, the connection information determination means 123 stores the application information and the connection ID of the application 111 (1) in the connection information in step S18.
The communication relay means 120 transmits the authentication result and the connection ID (1) to the application 111 (1) in step S19.

FIG. 4 is a diagram showing an example of connection information.
As shown in FIG. 4, the connection information includes a key table TB1 in which a key and data are associated with each other, and a connection ID table TB2 in which a connection ID and a logical connection are associated with each other.
The connection information determination means 123 newly creates a column in the key table TB1 with "connection destination information" and "connection group number (1)" as keys, and the connection destination information of the application 111 (1) is created in the created key column. , And the connection group number (1) are stored. Further, the connection information determination means 123 stores the authentication information, the logical connection number (1), and the connection ID (1) of the application 111 (1) in the data column corresponding to the key.

The connection group number (1) is a number preset in the application 111 (1), and is a number for distinguishing the logical connection 300. Further, the logical connection number (1) is a number preset in the logical connection 300 (1) and is associated with the connection group number.
Further, the connection information determination means 123 stores the connection ID (1) of the application 111 (1) in the connection ID column of the connection ID table TB2, and logically connects in the logical connection number column associated with the connection ID. Stores the logical connection number (1) of 300 (1).

The connection information includes the key table TB1 and the connection ID table TB2, but since the key table TB1 includes the connection ID and the logical connection number, the connection ID table TB2 may not be provided. However, since the connection information includes the connection ID table TB2, the information processing apparatus 100 can easily search for the logical connection number corresponding to the connection ID in the communication processing of the control system 1 described later.

b) In the case of application 111 (2) When the connection ID issuing means 122 receives the application information of application 111 (2) in step S11, the connection ID issuing means 122 issues the connection ID (2) in step S12.
In step S13, the connection information determining means 123 searches for the connection information stored in the connection information storage means 124 by using the "connection destination information" and the "connection group number" of the application information of the application 111 (2) as keys.
For example, when the application 111 (2) is the same as the "connection destination information" and the "connection group number (1)" of the application 111 (1), the connection information determination means 123 includes the connection information in FIG. 4 in step S14. It is determined that there is "connection destination information" and "connection group number (1)" of the same key.

In step S21, the authentication means 125 compares the authentication information of the application 111 (2) with the authentication information associated with the same key in the key table TB1 of FIG. 4, and determines whether or not they match. When it is determined that the authentication means 125 matches, the connection information determination means 123 stores the application information and the connection ID of the application 111 (2) in the connection information in step S18.
The communication relay means 120 transmits the authentication result and the connection ID (2) to the application 111 (2) in step S19.

FIG. 5 is a diagram showing an example of connection information.
As shown in FIG. 5, in the key table TB1, the connection ID (2) of the application 111 (2) is stored in the data column corresponding to the key. Further, in the connection ID table TB2, the connection ID (2) of the application 111 (2) is stored in the connection ID column, and the logical connection 300 (1) is stored in the logical connection number column associated with the connection ID. The logical connection number (1) is stored.

In step S13, the connection information determining means 123 searches for the connection information stored in the connection information storage means 124 by using the "connection destination information" and the "connection group number" of the application information of the application 111 (3) as keys.
For example, when the "connection group number (2)" of the application 111 (3) is different from the "connection group number (1)" of the application (1), the connection information determination means 123 can be used to obtain the connection information of FIG. 5 in step S14. It is determined that there is no "connection destination information" and "connection group number" of the same key in it.
In step S15, the transmission / reception means 121 connects to the transmission / reception means 210 of the control device 200 with a new logical connection 300 (2), and transmits the authentication information of the application 111 (3). The transmission / reception means 121 receives the authentication result from the control device 200 in step S16.
When the authentication is permitted in step S17, the connection information determination means 123 stores the application information and the connection ID of the application 111 (3) in the connection information in step S18.
The communication relay means 120 transmits the authentication result and the connection ID (3) to the application 111 (3) in step S19.

FIG. 6 is a diagram showing an example of connection information.
As shown in FIG. 6, the connection information determining means 123 newly creates a column in the key table TB1 with "connection destination information" and "connection group number (2)" as keys, and the application 111 is created in the created key column. The connection destination information of (1) and the connection group number (2) are stored. Further, the connection information determination means 123 stores the authentication information, the logical connection number (2), and the connection ID (3) of the application 111 (3) in the data column corresponding to the key.
The connection group number (2) is a number preset in the application 111 (3), and is a number for distinguishing the logical connection 300. Further, the logical connection number (2) is a number preset in the logical connection 300 (2) and is associated with the connection group number.
Further, the connection information determination means 123 stores the connection ID (3) of the application 111 (3) in the connection ID column in the connection ID table TB2, and logically connects in the logical connection number column associated with the connection ID. Stores the logical connection number (2) of 300 (2).

<Communication processing of control system 1>
Next, the operation related to the communication processing of the control system 1 according to the present embodiment will be described.
FIG. 7 is a flowchart illustrating the communication process of the control system 1.
The communication process shown in FIG. 7 is executed after the connection process shown in FIGS. 2 and 3 is performed, for example.

In step S51, the communication relay means 120 of the information processing device 100 receives the request to the control device 200 from the application 111 and the connection ID.

In step S52, the communication relay means 120 searches for a logical connection number corresponding to the connection ID received in step S51 based on the connection ID table TB2 of the connection information of FIG.

In step S53, the transmission / reception means 121 transmits the request and the connection ID received in step S51 to the control device 200 via the logical connection 300 of the logical connection number searched in step S52.

In step S71, the control device 200 processes the received request and generates a response.

In step S72, the control device 200 transmits the response generated in step S71 and the connection ID received from the information processing device 100 to the information processing device 100.

In step S54, the transmission / reception means 121 of the information processing apparatus 100 receives the response to the request transmitted in step S53 and the connection ID.

In step S55, the communication relay means 120 transmits the response received in step S54 to the application 111 indicated by the connection ID received in step S54.

As described above, the information processing apparatus 100 according to the embodiment issues a connection ID for each connection of the application 111. Further, the information processing apparatus 100 divides the application 111 into a plurality of groups based on the connection group number preset in the application 111, and sets the application 111 to use a different logical connection 300 for each group. When the information processing device 100 receives the request (data) to which the connection ID is added from the application 111, which logical connection 300 should be used to transmit the request (data) to the control device 200? It is possible to determine whether the communication is with the application 111.
As a result, the information processing device 100 can suppress the number of logical connections 300 with the control device 200 to a number smaller than the number of applications 111 even in a configuration in which there are a plurality of applications 111.

By doing so, the information processing device 100 can suppress the number of logical connections 300 with the control device 200 to one or an arbitrary number even in a configuration in which there are a plurality of applications 111. The information processing device 100 suppresses the consumption of CPU power and memory resources of the control device 200 more than necessary, so that the performance and stability of the control device 200 can be improved.
Further, the information processing device 100 may group the application 111 according to the operation content of the application 111, for example, an application that transmits / receives a large amount of data or an application that requires a quick response from the control device 200. ..
As a result, the information processing apparatus 100 separates the logical connection 300 used by the application 111, which is scheduled to communicate a large amount of data in advance, from the logical connection 300 used by the other applications 111. , The deterioration of the performance of the control device 200 can be suppressed more effectively.
