[0002] In FSoE (FailSafe over EtherCAT, an internationally standardized technology) protocol communication, its secure address serves as the only addressing method for the master station and slave stations. The current traditional method for allocating secure addresses to slave stations is to configure them through DIP switches.

[0003] However, when using DIP switches to allocate secure addresses to slave stations, it is necessary to add a design circuit for the DIP switches inside the slave stations, which increases the size and cost of the printed circuit board (PCB). Moreover, during the configuration process, since one master station can correspond to multiple slave stations simultaneously, each slave station needs to ensure the uniqueness of the configured secure address. At the same time, when new or internal modules need to be added or replaced in the slave station, it is also necessary to consider the original secure address situation to reconfigure non-duplicate secure addresses, and the overall configuration process is too cumbersome.

[0004] In view of the above technologies, seeking a secure address allocation method is an urgent problem for those skilled in the art. Summary of the Invention

[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0047] The core of the present application is to provide a secure address allocation method, device, electronic device and medium.

[0048] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0049] Figure 1 Flow chart of a secure address allocation method provided by an embodiment of the present application, including the following steps:

[0050] S10: Obtain the configuration range of the secure address.

[0051] S11: Generate the slave secure address based on the configuration range.

[0052] In a specific embodiment, the security address allocation method is applied to the master computer. That is, the software in the master computer first obtains the configuration range of the security address, specifying an initial range for generating the slave security addresses subsequently. The reason is as follows: The security address specifically includes 16 bytes, and the characters at different byte positions can be numbers, letters, etc. Therefore, each different byte corresponds to a relatively large range. If a corresponding slave security address is generated for each slave within such a range, there is no pattern, and it is also relatively complex to determine whether the currently generated slave security address is repeated. Therefore, in this application, before generating the slave security address, the configuration range of the security address is obtained, and then the slave security address is generated based on the configuration range. The multiple slave security addresses generated in this way are convenient for management, with simple operations, and it is also convenient to determine whether the currently generated slave security address is repeated with the previously generated slave security addresses.

[0053] Among them, the specific steps for obtaining the configuration range of the security address can be: The specific implementation method for obtaining the configuration range of the security address is: Obtain each historical security address stored in itself; Determine each address data range based on each security historical address; Determine the corresponding said configuration range based on each address data range.

[0054] And the specific steps for generating the slave security address based on the configuration range can be: The specific implementation method for generating the slave security address based on the configuration range is: Determine the byte range corresponding to each different byte according to the configuration range; Determine the characters corresponding to different bytes based on the corresponding byte range according to the preset numerical selection rule; Sort the characters corresponding to different bytes based on the preset byte sorting rule, and use the sorted array as the slave security address.

[0055] S12: Determine whether the slave security address is the same as each historical security address stored in itself.

[0056] S13: If the slave security address is the same as any one of the historical security addresses, return to the step of generating the slave security address based on the configuration range; if the slave security address is not the same as the historical security addresses, write the slave security address into the master station so that the master station and the corresponding slave can communicate according to the slave security address.

[0057] In a specific embodiment, since the purpose of the master station generating the slave station security address is to configure the slave station security address to the slave station through the master station, but one master station is connected to multiple slave stations. Therefore, during the process of the master station generating the slave station security address, actually multiple slave station security addresses are generated, and each of them is specifically configured for each slave station so that the master station can communicate with the corresponding slave station according to the current slave station security address in the future. Therefore, it is necessary to ensure that each slave station security address is unique and will not be repeated with other slave station security addresses. At the initial stage of configuration, it is required that the master station determines whether the slave station security address is the same as each historical security address stored in itself. If the slave station security address is the same as any one of the historical security addresses, it means that the currently generated slave station security address does not meet the requirements, and the step of generating the slave station security address based on the configuration range needs to be returned, that is, a unique slave station security address is regenerated; if the slave station security address is different from all the historical security addresses, it means that the currently generated slave station security address meets the requirements and is unique. At this time, the master station sends the slave station security address to the master station, and then the master station configures it to a slave station without an address so that the current and subsequent master stations and slave stations can communicate through the slave station security address.

[0058] The communication between the master station and the slave station includes the following steps:

[0059] Step 1: The master station and the slave station are powered on respectively. If the power-on fails.

[0060] Step 2: The master station needs to send communication instructions to each connected slave station. (The communication instructions include the address corresponding to the slave station that needs to communicate).

[0061] Step 3: Each slave station makes its own judgment according to the slave station security address in the communication instruction. If the slave station security address corresponding to itself is the same as the address in the communication instruction, communication with the master station is achieved; if the slave station security address corresponding to itself is different from the address in the communication instruction, communication with the master station is achieved.

[0062] Step 4: After the master station and the slave station communicate through the slave station security address, they can transmit security communication and application parameters through the current communication channel, which specifically includes the watchdog interval, application parameter length, and application data.

[0063] It should be noted that the specific steps for obtaining the configuration range of the security address and the specific steps for the slave station security address based on the configuration range provided in the embodiments of the present application are only one possible implementation method, but not limited to only this implementation method, and can be set by the user according to needs.

[0064] A secure address allocation method provided by the present application is applied to a master computer and includes: obtaining a configuration range of secure addresses; generating a slave secure address based on the configuration range; determining whether the slave secure address is the same as each historical secure address stored by itself; if the slave secure address is the same as any one of the historical secure addresses, returning to the step of generating the slave secure address based on the configuration range; if the slave secure address is different from each historical secure address, writing the slave secure address into the master computer so that the master computer and the corresponding slave can communicate according to the slave secure address. It can be seen that the present application uses a software method to configure and generate the slave secure address, which not only reduces the hardware design cost of configuring the slave secure address, but also simplifies the actual application complexity and is convenient for maintenance.

[0065] On the basis of the above embodiment, as a preferred embodiment, the specific implementation manner of the above S10 step: obtaining the configuration range of the secure address is: obtaining each historical secure address stored by itself; determining each address data range based on each secure historical address; determining the corresponding configuration range based on each address data range.

[0066] In a specific embodiment, whenever the master computer generates a slave secure address, that is, stores a slave secure address, then the slave secure address at this time will be used as the historical secure address of the next slave secure address. In order to avoid the newly generated slave secure address from being repeated with the previously generated slave secure address and simplify the process of determining whether the currently generated slave secure address is repeated with the previously generated slave secure address, it is necessary to obtain each historical secure address stored by itself, then determine each address data range according to each secure historical address, and finally fuse each address data range to finally obtain a configuration range.

[0067] Among them, the master computer is connected to multiple slaves, but not all slaves have slave secure addresses. Therefore, the secure slave addresses corresponding to some slaves will be stored in the master computer as each historical secure address stored by itself. Or all slaves do not have corresponding slave secure addresses, then a part of each historical secure address that meets the address specification can be stored in the master computer in advance as the basis for the master computer to generate the slave secure address.

[0068] The specific implementation manner of the above S11 step: generating a slave secure address based on the configuration range is: determining the byte range corresponding to different bytes according to the configuration range; determining the characters corresponding to different bytes based on the corresponding byte range according to a preset value selection rule; sorting the characters corresponding to different bytes based on a preset byte sorting rule, and using the sorted array as the slave secure address.

[0069] In a specific embodiment, the number of bytes of the slave security address is 16 bytes, and the initial configuration range of the 16-byte slave security address is: 0000 0000 0000 0000 - 0000 0000 0000 FFFF. According to each historical security address, a relatively smaller configuration range can be further divided on the basis of the initial configuration range. Specifically, the byte ranges corresponding to different position bytes are determined within the configuration range, and then characters (such as 0, 1, F, etc.) corresponding to different bytes are determined based on the corresponding byte ranges according to a preset value selection rule (for example: random selection rule or sequential selection rule). Then, the characters corresponding to different bytes are sorted based on a preset byte sorting rule, which can also be understood as re-sorting according to the original byte positions. The sorted array is used as the slave security address. For example: 0000 0000 0010 0100.

[0070] Based on the above embodiment, as a preferred embodiment, for the above S14 step: If the slave security address is different from each historical security address, the specific implementation of writing the slave security address into the master station is as follows: If the slave security address is different from each historical security address, write the slave security address into the corresponding object dictionary; where the object dictionary includes: slave security address, configuration parameters, and configuration variables; write the object dictionary into the master station.

[0071] After writing the slave security address into the master station, it further includes: performing an address read-back on the slave security address, and controlling the slave display target indication signal corresponding to the slave security address during the address read-back phase.

[0072] In a specific embodiment, the present application uses an object dictionary to write the slave security address into the master station. That is to say, the host computer generates a unique slave security address through software, then writes the slave security address into the object dictionary, and then writes the object dictionary into the master station, so that the master station writes the object dictionary into the slave station through the EtherCAT protocol to implement the address configuration process.

[0073] During this process, after the host computer configures the slave security address through the configuration interface, it is also necessary to read back the configured slave security address through the software of the host computer. Each time the slave security address corresponding to the slave is read back, it controls the corresponding slave display target indication signal (for example: controlling the LED indicator in the slave to blink for about 3 - 5 seconds) to indicate the specific position of the currently read-back slave, so that the operation can be detected arbitrarily.

[0074] Among them, it should be noted that after the host computer writes the object into the master station, the master station writes the object dictionary into the slave station through the EtherCAT protocol. Then, the micro control unit in the slave station stores the slave station security address in the object dictionary into the memory in the micro control unit. The controller of the slave station then loads the slave station security address from the memory and verifies it. If the verification is correct, the security protocol stack configured with the correct slave station security address is used, and the correct slave station security address is used each time communicating with the station. After verification, the slave station downloads the verification result (which can also be understood as the configuration result) to the master station again; the master station parses the slave station security address again and uses the configured slave station security address to communicate with the slave station during communication.

[0075] Therefore, the hardware schematic diagram corresponding to the current security address allocation method is as shown in Figure 2 Figure 5, which includes a host computer 1, a master station 2, and two slave stations 3. The master station includes a controller 401, a master station central processing unit 402, and a master station network configuration file 403; the slave module in the slave station 3 includes a slave station central controller 301 and a slave station network configuration file 302, and the slave station security address is included in the slave station network configuration file 302 and the master station network configuration file 203. The host computer 1 is connected to the master station 2 through Ethernet, and the master station 2 is connected to the first slave station 3 through the EtherCAT protocol. At the same time, the first slave station 3 and the second slave station 3 are also connected through the EtherCAT protocol. The host computer 1 generates the slave station security address through software and configures it to the corresponding slave station 3 through the master station 2 to realize the communication between the master station 2 and the slave station 3.

[0076] Among them, it should be noted that the embodiment provided in this application is only one implementable way, but it is not limited to only this implementable way and can be set by oneself according to the needs of users.

[0077] It can be seen that this application uses a software method to configure and generate the slave station security address, which not only reduces the hardware design cost of the slave station security address configuration, but also simplifies the actual application complexity and is convenient for maintenance.

[0078] Figure 3 The flowchart of a security address allocation method provided in another embodiment of this application is as shown in Figure 3 Figure 6, and includes the following steps:

[0079] S20: Obtain the object dictionary written by the host computer to the master station based on a preset network protocol.

[0080] S21: Obtain the slave station security address in the object dictionary.

[0081] S22: Perform an address check on the slave station security address to obtain a check result.

[0082] S23: If the verification result indicates correct verification, send the verification result to the master station and communicate with the master station through the slave station security address.

[0083] S24: If the verification result indicates incorrect verification, send the verification result to the host computer through the master station so that the host computer can display the verification result.

[0084] In a specific embodiment, Figure 3 The method flow shown is applied to the slave station. The host computer first sends the generated slave station security address to the master station in the form of an object dictionary, and then the master station and the corresponding slave station are connected using a preset network protocol (for example: EtherCAT protocol) for transmitting the object dictionary. The slave station obtains the slave station security address in the object dictionary and then verifies it. If the verification is correct, the verification result is sent to the master station so that the current or subsequent master station can communicate with the corresponding slave station through the slave station security address; if the verification result indicates incorrect verification, the verification result is sent to the host computer through the master station so that the host computer can display the verification result and at the same time so that the operator can determine which slave station is communicating with the master station currently.

[0085] A security address allocation method provided by the present application is applied to the slave station and includes: obtaining the object dictionary written by the host computer to the master station based on a preset network protocol; obtaining the slave station security address in the object dictionary; performing address verification on the slave station security address to obtain a verification result; if the verification result indicates correct verification, send the verification result to the master station and communicate with the master station through the slave station security address. It can be seen that in the present application, the host computer configures and generates the slave station security address in a software manner and distributes the configured slave station security address through the object dictionary of the EtherCAT protocol, which not only reduces the hardware design cost of configuring the slave station security address, but also simplifies the actual application complexity and is convenient for maintenance.

[0086] In the above embodiment, the security address allocation method is described in detail. The present application also provides an embodiment corresponding to the security address allocation device. It should be noted that the present application describes the embodiment of the device part from two perspectives, one is from the perspective of functional modules and the other is from the perspective of hardware.

If the slave station security address is different from each historical security address, the slave station security address is written into the master station so that the master station and the corresponding slave station can communicate according to the slave station security address.
