The mode determination module 290 can define that the trigger mode of the communication command that is not collected for the first time is "period transmission".

The trigger mode determining module 290 may also calculate the trigger period of the communication command according to the interval time collected by the command collection module 220 after the trigger mode for defining the communication command is “period transmission”, and the calculation manner includes but not When the command collection module 220 collects the communication command three times or more, the trigger mode determining module 290 collects the statistical value of the average or median interval of the communication command collection module 220, and The calculated statistical value is used as the trigger period.

In practice, the setting module 210, the command collecting module 220, the condition determining module 230, the display module 240, the data corresponding module 250, and the trigger mode determining module 290 are not necessarily required to be the gateway 100. The operation of the module may also be included in the utility as shown in "FIG. 2B". After the utility is executed, the system 200 generated includes the above-described setting module 210, command collection module 220, and conditions. The determination module 230, the display module 240, the data correspondence module 250, and the trigger mode determination module 290. Since each module operates in the same manner as described above, it will not be described again.

Next, an operational system and method of the present invention will be described with reference to an embodiment, and reference is made to the flowchart of the method for automatically configuring the learning command proposed by the present invention in "3A". In this embodiment, it is assumed that the first communication protocol used by the first network 300 is a Modbus protocol, and the second communication protocol used by the second network 400 is a PROFIBUS protocol.

Since the communication protocol used by the first network 300 and the second network 400 is different, it is necessary to exchange data between the first network 300 and the second network 400 through the gateway 100. If the gateway 100 includes the present invention, the setting module 210 of the present invention can provide the communication parameters required by the user to set the first communication interface 111 of the gateway 100 to use the Modbus protocol (first communication protocol) (step 501). . In this embodiment, the user can set the operation mode, the transmission speed, the parity, the stop bit, and the interface type of the first communication interface 111 through the setting module 210.

After the setting module 210 provides the first communication interface 111 of the user setting gateway 100 to use the communication parameters of the first communication protocol (step 501), the first communication interface 111 can be connected to the gateway 100 and the first network 300. (Step 510). In this embodiment, if the interface type of the first communication interface 111 is RS-232, it means that there is only the primary station device in the first network 300, and the gateway 100 will be the primary station device in the first network 300. Connected, the gateway 100 is the slave device in the first network 300. If the interface type of the first communication interface 111 is RS-422 or RS-485, it means that the gateway 100 is multi-dropped on the first network 300. At this time, the first network 300 includes The master station device and more than one slave station device, and the gateway device 100 is a probe device on the first network 300. The master station device may be a Programmable Logic Controller (PLC), a Human Machine Interface (HMI), or a computer that executes test software.

After connecting the gateway 100 and the first network 300 (step 510), the command collection module 220 can collect the respective communication commands transmitted in the first network 300 through the first communication interface 111 (step 520). If the gateway 100 is a slave device in the first network 300, the command collection module 220 also sends a response through the first communication interface 111 to the received communication command after receiving the communication command. Master station device. In this embodiment, the command collection module 220 can further determine whether the gateway 100 supports the first communication interface 111 after receiving the communication command on the first communication interface 111 as shown in the flow of FIG. 3B. Receiving the communication command (step 521), if the gateway 100 supports the communication command, recording the communication command (step 529), that is, recording the slave address/target node address and the source node in the communication command Address, command code, function code, data start address / memory address, data volume, and target data. If the gateway 100 does not support the communication command, the command collection module 220 can record only the slave address/target node address in the record communication command (step 525).

If the trigger mode determination module 290 is included in the gateway 100, after the command collection module 220 collects the communication command, the trigger mode determination module 290 can determine the trigger mode of the collected communication command. The trigger mode judging module 290 can first determine whether the communication command collected by the command collection module 220 is collected for the first time (step 532), as shown in the flow of the "3C" diagram. If so, the trigger mode judging module 290 can Defining the trigger mode of the communication command is "data change" (step 534). If not, the trigger mode determining module 290 can define that the trigger mode of the communication command is "period transmission" (step 536), and according to the communication command The trigger period of the communication command is calculated by the interval collected by the command collection module 220 (step 538).

Returning to "FIG. 3A", when the command collection module 220 collects the communication command (step 520), the condition determination module 230 also determines whether the stop collection condition is satisfied (step 550). In the present embodiment, it is assumed to stop. The collection condition is that the time for collecting the communication command reaches three system cycles, and the condition determination module 230 determines that the collection condition is satisfied after the time elapsed after the command collection module 220 collects the communication command reaches three system cycles. The command collection module 220 will stop collecting communication commands. At this time, the gateway 100 completes the setting of each communication command used in the first network 300 according to the content of the communication command collected by the command collection module 220, and thus can become the new network 300. The primary station device replaces the original primary station device 390. If the gateway 100 is originally tapped on the first network 300 (the gateway 100 is a detecting device), the user needs to interrupt the connection of the original primary station device 390 with the first network 300 to avoid subsequent gateways. When the device 100 reads and writes data from the slave device (the first device 310/320/330), it is interfered by the original master station device 390. If the gateway 100 is originally docked with the original primary station device 390 (the gateway 100 is a secondary device), the user needs to change the gateway to the first device 310/320/ in the first network 300. 330 (slave device) docked for subsequent data reading and writing.

After the gateway 100 becomes the primary station device of the first network 300, that is, the condition determining module 230 determines that the stop collection condition is satisfied, and after the command collection module 220 stops collecting the communication command, the data corresponding module 250 can The storage address of the target data read and written by each collected communication command corresponds to the communication output module of the second device 410 for accessing the target data (step 570).

In this embodiment, it is assumed that during the process of collecting the communication command by the command collection module 220, three read communication commands are collected, wherein the collected communication command indicates that the user wants to operate the second network 400. The second device 410 reads the data of the first device 310 in the first network 300, and as shown in "FIG. 4A", the gateway 100 transmits a communication command (first communication command) indicated as a read request. To the first device 310, after receiving the read request, the first device 310 will return the target data of 50 words according to the read request, and the data corresponding module 250 will transmit according to the gateway 100. Reading the function code and the data amount in the request, calculating the data length of the target data read by the read request, and writing the target data returned by the first device 310 into the internal memory 120 of the gateway 100. Enter the block. Similarly, the gateway 100 will also transmit read requests (second communication commands and third communication commands) to other first devices (320, 330) in the first network 300, if the first device 320 and the first The device 330 returns the target data of the 24-word group and the 3-bit group respectively, and the data corresponding module 250 can write the target data returned by the first device 320 and the first device 330 into the internal memory 120, the first device. The storage space after the target data returned by 310.

Then, the data corresponding module 250 can be configured with the PROFIBUS protocol communication output module to store the storage space of the target data returned by the first device 310, the first device 320, and the first device 330. Since the target data has a total of 151 bits. Therefore, the data corresponding module 250 can be configured with a 64-word group and a 23-bit communication output module (using a minimum of communication output modules) or a 50-word group, a 24-word group, and a 3-byte group. The communication output module (using the communication input/output module corresponding to the communication command) is used to store the storage space of the target data, and then the second device 410 can be read and stored in the internal memory through the configured communication output module. Target data in 120.

If the command collection module 220 collects the communication command, two written communication commands are collected, wherein the collected communication command indicates that the user desires to use the second device 410 in the second network 400. The data is written into the first device 310 in the first network 300. As shown in the "FIG. 4B", after the data corresponding module 250 is configured with 63 words and 7-bit communication output modules, The second device 410 can write the target data into the output block of the internal memory 120 of the gateway 100 through the communication output module, and use the 63-character and 7-bit communication output module in the second device 410. After the group writes the target data into the storage locations corresponding to the first device 310 and the first device 320 in the internal memory 120, the gateway 100 will trigger according to the write request (the fourth communication command and the fifth communication command). The mode transmits a write request including the target data of 63 words and 7 bytes to the first device 310 and the first device 320, that is, according to the trigger period calculated by the trigger mode determination module 290, and periodically transmits Write request, or detect internal A write request is transmitted when the data in the output block of the memory 120 changes.

After the first device 310 receives the write request, the target data of 63 words will be stored according to the write request. Similarly, after receiving the write request, the first device 320 will store 7 bits according to the write request. The target data of the tuple. In this manner, the second device 410 can write the target data to the first devices 310, 320 using different communication protocols through the gateway 100.

In summary, it can be seen that the difference between the present invention and the prior art is that there is a communication command transmitted by using the collected in the first network, and the storage address of the target data read and written by the communication command is corresponding to the second device. The technical means for accessing the communication data of the target data to the gateway device can solve the problem that the heterogeneous network gateway device set in the prior art is time-consuming and difficult to set, thereby achieving the lifting gateway device The technical efficiency of the efficiency of the configuration settings.

Furthermore, the learning command of the present invention can be implemented in hardware, software or a combination of hardware and software by means of automatic configuration setting, or can be implemented in a centralized manner in a computer system or spread over several different components by different components. Even the decentralized way of implementing computer systems.

While the embodiments of the present invention have been described above, the above description is not intended to limit the scope of the invention.

A system for learning commands to automatically configure settings is applied to a gateway device that uses a first communication protocol to connect to a first network including a first device through a first communication interface, and Using a second communication protocol to connect to a second network including a second device through a second communication interface, the system includes at least: a setting module configured to set the gateway to use a first communication protocol a communication parameter; a condition determination module for determining whether a stop collection condition is satisfied; and a command collection module for collecting at least one communication command transmitted in the first network through the first communication interface, Until the condition determination module determines that the stop collection condition is satisfied; and a data corresponding module for storing a target data read and written by the communication command in the internal memory of the gateway, and storing The storage address of the target data corresponds to at least one communication input/output module, so that the second device accesses the target data via the communication output module. A gateway for automatically configuring a setting command, the gateway comprising at least: an internal memory; a first communication interface for connecting to a first network using a first communication protocol, the first The network includes at least one first device; a second communication interface for connecting to a second network using a second communication protocol, the second network includes at least one second device; and a setting module for Setting a first communication interface to use a first communication protocol communication parameter; a condition determination module for determining whether a stop collection condition is satisfied; and a command collection module for collecting the first communication interface At least one communication command transmitted in the first network until the condition determining module determines that the stop collection condition is satisfied; and a data corresponding module for storing a target data read and written by the communication command In the internal memory, the storage address storing the target data is corresponding to the at least one communication input and output module, so that the second device accesses the target data via the communication output module. For example, the learning command described in claim 8 is configured to automatically configure the gateway device, wherein the command collection module sets the gateway device as a slave device/detection device in the first communication protocol, thereby receiving / Detecting each of the communication commands sent by the primary station device in the first communication protocol to each of the target nodes having different slave addresses or different target node addresses, and receiving/detecting each of the communication commands Record these communication commands after the command. For example, the learning command described in claim 8 of the patent application is automatically configured to set the gateway, wherein the gateway further includes a trigger mode determining module for determining whether each communication command is collected for the first time. When the communication command is collected for the first time, the trigger mode for defining the first collected communication command is "data change", and when the communication command is not collected for the first time, the trigger mode of the non-first collected communication command is defined. It is "sent periodically" and calculates the trigger period of the communication command that is not collected for the first time. For example, the learning command described in claim 8 is configured to automatically configure the gateway device, wherein the command collection module is further configured to determine whether the gateway supports the communication commands, when the gateway supports the When the communication commands are used, the communication commands are recorded, and when the gateway does not support the communication commands, the slave address or the target node address in the communication commands are recorded. For example, the learning command described in claim 8 of the patent application is automatically configured to set the gateway, wherein the stop collection condition is that the time for collecting the communication command reaches a specific system period, and the number of collected communication commands is no longer in a specific time. Increased, or as defined by the communication command received, the number of communication commands received, and/or the time elapsed to collect the communication command.
