Description
Technical Field
Embodiments of the present disclosure relate generally to bus communications and, more particularly, relate to a method, apparatus, and computer program product for configuring a slave device.
Background
Modbus is a serial communication protocol that has become an industry standard for industrial field communication protocols and is now a common connection between industrial electronic devices.
The Modbus protocol is a master/slave architecture protocol. One node is the master node and the other nodes participating in communications using the Modbus protocol are slave nodes. Each slave device has a unique address. One ModBus command contains the Modbus address of the device intended to execute. All devices receive the command, but only the device at the specified location executes and responds to the command, except for address 0. Since the command specifying address 0 is a broadcast command in the Modbus protocol, all devices receiving the command will operate, but will not respond to the command.
Traditionally, the configuration of the address for the slave device has been accomplished using knobs or Human Machine Interface (HMI), which requires a significant amount of physical device hardware. As the number of slave devices increases, the required physical device hardware causes a significant increase in hardware cost overhead.

Detailed Description
Hereinafter, various exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that the drawings and description relate to exemplary embodiments only. It is noted that from the following description, alternative embodiments of the structures and methods disclosed herein are readily contemplated and may be employed without departing from the principles of the present disclosure as claimed.
It should be understood that these exemplary embodiments are given solely for the purpose of enabling those skilled in the art to better understand and to practice the present disclosure, and are not intended to limit the scope of the present disclosure in any way.
The terms "including," comprising, "and the like, as used herein, are to be construed as open-ended terms, i.e.," including/including but not limited to. The term "based on" is "based, at least in part, on". The term "some embodiments" means "at least some embodiments"; the term "another embodiment" means "at least one additional embodiment". Relevant definitions for other terms will be given in the following description.
Fig. 1 illustrates a schematic diagram of an exemplary system 100 in which embodiments of the present disclosure may be implemented.
As shown in FIG. 1, a master device 110 and a plurality of slave devices 120-1, 120-2, 120-3, and 120-4 are included in a system 100. The slave devices 120-1, 120-2, 120-3, and 120-4 are connected to the master device 110 through a bus, thereby enabling communication with the master device. Communication between the master device 110 and the plurality of slave devices 120-1, 120-2, 120-3, and 120-4 (hereinafter collectively referred to as slave devices 120) shown in FIG. 1 may employ, for example, a Modbus bus communication protocol. Each slave device 120 has a unique address.
In the present disclosure, the master device 110 may be regarded as a device acting as a master node in an industrial control system, such as the system 100, for example. The slave device 120 may for example be seen as a device acting as a slave node in an industrial control system, e.g. in the system 100. For example, the slave device 120 may be a smart meter, a sensor, a smart building, and the like.
It should be understood that the number of slave devices shown in fig. 1 is merely exemplary and is not intended to limit the scope of the present application. Any number of slave devices is possible, as long as the system 100 allows.
To enable communication between the master device 110 and the slave device 120 to enable the master device 110 to send control signals to the slave device 120 or to receive information, such as data collection information, from the slave device 120. The master device 110 needs to know the communication address specific to the slave device 120.
As described above, currently, under a system architecture employing the Modbus protocol, the master device 110 needs to install a large amount of physical hardware, such as a knob or a human-machine interface (HMI) to configure the communication address of the slave device 120, so as to realize communication between the master device 110 and the slave device 120. This approach requires a large amount of physical device hardware, resulting in a large hardware cost overhead.
In view of the above problems, embodiments of the present disclosure provide a method for configuring slave devices and corresponding master and slave devices, such that the master devices can configure slave-specific private communication addresses in a simple manner using the Modbus bus communication protocol without additional physical hardware. In this way, hardware overhead and system cost are saved.
The principles and implementations of the present disclosure will be described in detail below with reference to fig. 2, where fig. 2 illustrates a process 200 according to an example embodiment of the present disclosure. For discussion purposes, process 200 will be described with reference to fig. 1. Process 200 may involve a configuration method of slave device 120.
As shown in fig. 2, the master device 110 obtains 210 identity information associated with the slave device 120. In the system 100, the identity information of the slave devices 120 may be obtained, for example, from factory settings of the slave devices 120, each slave device 120 having unique identity information.
In some embodiments, the master device 110 may obtain the serial number of the slave device 120. In some embodiments, the master device 110 may also obtain, for example, an index to a register set associated with the serial number of the slave device in the slave device 120, the register set being used to configure the communication address.
Generally, there are several registers at each slave device 120 to store data that the slave device 120 needs to save. Taking a smart meter as an example, its register may store parameters related to voltage, current, etc., for example. Further, for each slave device 120, there are several registers for holding the serial number of the slave device 120, and a register for storing the communication address of the slave device 120.
For each slave device 120, there is a list, hereinafter referred to as a register table, for recording the type of register set that the slave device 120 has. The register table may also be obtained from factory settings of the slave device 120. An example of a list of register sets associated with the serial number of the slave device 120 is shown in the table below.
Table 1: register set list with slave device 120
As shown in table 1, registers 3005 to 3005+ n store serial numbers of slave devices, and register 3005+ n +1 is used to store a specific communication address specific to the slave device to be configured for the slave device 120 by the master device 110. In other words, the indexes of the register sets associated with the serial numbers of the slave devices in the slave device 120 are 3005 to 3005+ n.
It should be understood that master device 110 may also obtain other identity information, such as other aspects of the index of the register set, for example, if desired.
Once the master device 110 acquires the identity information of the slave device 120, configuration information specific to the slave device 120 is generated based on the identity information. To configure the address of the slave device 120, the master device 110 sends 220 the configuration information to the slave device 120.
In some embodiments, master device 110 may send configuration information to each slave device 120 via a broadcast address for communication with slave devices 120. The broadcast address under the Modbus protocol is "0". Master device 110 may send configuration information to each slave device 120, for example, via bus 130.
In some embodiments, master device 110 may send a private communication address specific to slave device 120. In some embodiments, master device 110 may, for example, send a start address and an end address of a register set associated with a sequence number in slave device 120.
In some embodiments, master device 110 may send the configuration information shown in the table below to slave device 120.
Table 2: configuration information
In some embodiments, as shown in table 2, in addition to the private communication address specific to the slave device 120 and the start and end addresses of the register set associated with the serial number in the slave device 120. The configuration information may further include, for example, an address configured in a factory setting of the slave device 120, a function code of the configuration information, data of each bit of a serial number of the slave device 120, and information of Cyclic Redundancy Check (CRC).
In the above, it has been mentioned that by broadcasting the address, the master device 110 may send the configuration information to each slave device 120, e.g. over the bus 130. Although slave device 120 may not reply to a message sent by the broadcast address, slave device 120 may be configured with the received configuration information once slave device 120 (e.g., slave device 120-1) finds that the configuration information is specific to slave device 120. Conversely, once slave device 120 (e.g., slave device 120-2) determines that the configuration information is not for configuring slave device 120, it discards the configuration information. This ensures that the slave device 120 receives configuration information that matches itself accurately and uses the configuration information to configure the communication address.
In some embodiments, the slave device 120 may receive a private communication address specific to the slave device, a serial number of the slave device 120, and a start address and an end address of a register set associated with the serial number in the slave device 120.
Upon receiving the configuration information from the slave device 120, the slave device 120 determines 230 whether the configuration information matches the slave device 120.
In some embodiments, the slave device 120 may retrieve a register set table associated with its own serial number. As already mentioned above, the register set table is stored at the slave device 120 and may indicate the serial number of the slave device. The slave device 120 may determine the validity of the serial number of the slave device in the configuration information and the start address and the end address of the register set associated with the serial number in the slave device based on the register set table. If the validity is successfully verified, slave device 120 may determine that the configuration information matches the slave device.
In some embodiments, the slave device 120 may, for example, compare a serial number stored in a register set table with the serial number of the slave device in the configuration information. If the two serial numbers are identical, the serial number of the slave device in the configuration information is considered to be valid, so that the configuration information can be considered to be matched with the slave device 120. Since the serial number that each slave device 120 has is unique.
If it is determined that the configuration information matches the slave device 120, the slave device 120 configures an address of the slave device 120 based on the configuration information.
In some embodiments, slave device 120 may obtain a private communication address specific to slave device 120 from the configuration information and configure the private communication address as the address of slave device 120.
In this way, the specific communication address specific to the slave device 120 can be accurately configured within the framework of the Modbus bus communication protocol in a simple manner without the use of additional hardware.
It has been mentioned above that the slave device 120 is able to receive the configuration information sent via the broadcast address and configure the slave device 120 if the configuration information matches. However, the slave device 120 does not reply with information from the broadcast address. That is, the master device 110 does not know whether the slave device 120 successfully configured the private communication address. Therefore, the master device 110 needs to further verify whether the previously transmitted configuration information of the slave device 120 is accepted by the slave device 120 based on the private address previously configured for the slave device 120.
The master device 110 may send 240 the test information to the slave device 120 via a private communication address specific to the slave device 120. If the slave device 120 receives the test information via the private communication address, a reply message is sent 250 to the master device 110. Once the master device 110 receives the reply information, it can be determined that the address of the slave device 120 is successfully configured.
In this manner, the master device can configure the slave-specific communication addresses in a simple manner using the Modbus bus communication protocol without requiring additional physical hardware, thereby saving hardware overhead and system cost.
Fig. 3 shows a flow diagram of a communication method 300 according to an embodiment of the present disclosure. In some embodiments, the method 300 may be implemented by the master device 110 in the system 100, for example, may be implemented by a processor or processing unit of the master device 110. In other embodiments, the method 300 may also be implemented by a computing device separate from the master device 110, or may be implemented by other units in the system 100. For ease of discussion, the method 300 will be discussed in conjunction with FIG. 1.
At 310, the master device 110 obtains identity information associated with the slave device 120.
In some embodiments, master device 110 may obtain the following: a serial number of the slave device; and an index of a register set for configuring a communication address in the slave device in association with the serial number.
At 320, based on the identity information, the master device 110 generates configuration information specific to the slave device 120.
At 330, the master device 110 sends configuration information to the slave device 120 to configure the address of the slave device 120.
In some embodiments, master device 110 may send configuration information to slave device 120 via a broadcast address used for communication between master device 110 and slave device 120.
In some embodiments, master device 110 may send the following: a slave device specific private communication address; a serial number of the slave device; and a start address and an end address of a register set associated with the sequence number in the slave device.
In some embodiments, master device 110 also sends test information to the slave device via a private communication address specific to slave device 120. If the master device 110 receives the reply information from the slave device 120, the master device 110 determines that the address of the slave device is successfully configured.
Fig. 4 shows a flow diagram of a communication method 400 according to an embodiment of the present disclosure. In some embodiments, the method 400 may be implemented by the slave device 120 in the system 100, for example, may be implemented by a processor or processing unit of the slave device 120. In other embodiments, method 400 may also be implemented by a computing device separate from slave device 120, or may be implemented by other units in system 100. For ease of discussion, the method 400 will be discussed in conjunction with FIG. 1.
At 410, the slave device 120 receives slave-specific configuration information from the master device. The configuration information is generated by the master device based on identity information associated with the slave device.
In some embodiments, slave device 120 may receive the following: a slave device specific private communication address; a serial number of the slave device; and a start address and an end address of a register set associated with the sequence number in the slave device.
In some embodiments, slave device 120 may receive configuration information from the master device via a broadcast address used for communication between master device 110 and slave device 120.
At 420, the slave device 120 determines whether the configuration information matches the slave device.
In some embodiments, the slave device 120 may retrieve a register set table associated with the serial number of the slave device. The register set table is stored at the slave device and indicates a serial number of the slave device. The slave device 120 may determine the validity of the serial number of the slave device in the configuration information and the start address and the end address of the register set associated with the serial number in the slave device based on the register set table. If the validity is successfully verified, slave device 120 may determine that the configuration information matches the slave device.
At 430, if the slave device 120 determines that the configuration information matches the slave device, the slave device 120 configures an address of the slave device based on the configuration information.
In some embodiments, the slave device 120 may obtain a slave-device-specific private communication address from the configuration information and configure the private communication address as the address of the slave device.
In some embodiments, slave device 120 may also receive test information from master device 110, which the master device sent using the private communication address. In addition, the slave device 120 may also send reply information to the master device.
