In a possible application scenario of an I/O module (hereinafter, also referred to as an I/O module), a field engineer converts an I/O module a1 originally running in the a station into the B station for use, and then converts an a1 module back into the a station for use, since the a1 module is reconfigured while the B station is in use, the configuration information of the a module has been changed, and at this time, the a module is converted back into the a station for use, the configuration of the a station cannot be adapted, and unpredictable errors may be generated due to errors in the configuration information. Therefore, how to timely discover the change of the configuration information of the I/O module so as to timely control the change of the configuration information of the I/O module is a problem to be solved.
One or more embodiments of the present specification provide a method for replacing a configurable input/output module, the method being applied to a host controller, wherein the input/output module may be a configurable input/output module, and fig. 1 is a flowchart illustrating a method for replacing a configurable input/output module according to one or more embodiments of the present specification, as shown in fig. 1, the method comprising:
step 101: sending a request message for reading an identification code to an input/output module at a preset time interval, wherein the identification code is used for identifying the input/output module;
for example, after the main controller is powered on every time, an information frame is sent to the input/output module at a preset time interval to request to acquire the identification code of the input/output module.
Alternatively, the identification code of the input/output module may be represented by a string of characters, for example, to identify the information of the input/output module.
Step 102: receiving a first identification code sent by the input/output module;
optionally, the input/output module may have a first identification code pre-stored therein, and the first identification code may be generated by the input/output module according to the configuration information of the input/output module and the CPU global unique ID of the input/output module.
Step 103: comparing the first identification code with a second identification code stored in advance, wherein the second identification code is generated by the main controller according to the configuration information of the input/output module and the identification information of the input/output module;
optionally, before step 103, the main controller receives configuration information of the input/output module from the user, and issues the configuration information to the input/output module so that the input/output module performs configuration according to the configuration information, and the main controller requests the input/output module to obtain identification information of the input/output module, and generates a second identification code according to the identification information and the configuration information of the input/output module. After the main controller obtains the first identification code from the input/output module, whether the input/output module is changed or not is determined by comparing the first identification code with the second identification code, if the first identification code is consistent with the second identification code, the input/output module is not changed, and if the first identification code is inconsistent with the second identification code, the input/output module is changed.
Step 104: and under the condition that the first identification code is inconsistent with the second identification code, issuing target configuration information to the input/output module.
Optionally, when it is determined in step 103 that the first identification code is not consistent with the second identification code, it is determined that the input/output module is changed, at this time, the configuration information in the input/output module is not consistent with the target configuration information of the input/output module stored in the main controller, and in order to ensure that the input/output module can normally operate, the main controller may issue the target configuration information to the input/output module, so that the input/output module updates to its own configuration information according to the target configuration information, and operates with the target configuration information.
In one or more embodiments of the present disclosure, a main controller periodically obtains a first identification code of an input/output module, compares the first identification code with a second identification code stored in advance, determines whether the input/output module has been changed through uniqueness of the identification code of the input/output module, and sends target configuration information to the input/output module when the input/output module has been changed, so that the input/output module can be configured according to the target configuration information, thereby achieving an objective of automatically synchronizing configuration information of the input/output module without manual intervention, facilitating configuration of the input/output module, and improving configuration efficiency.
The above-described change of the module a means a case where the module a is connected by replacing it with another module at the interface to which the module a is originally connected.
In one or more embodiments of the present disclosure, the method for replacing a configurable input/output module may further include:
receiving target configuration information for the input/output module; for example, user configuration information for an input/output module is received.
Sending the target configuration information to the input/output module and requesting to acquire identification information of the input/output module; and sending the target configuration information to the input/output module so that the input/output module performs configuration according to the target configuration information.
Receiving the identification information sent by the input/output module;
and generating the second identification code according to the target configuration information and the identification information. After the second identification code is generated, the second identification code can be stored, and the corresponding relation between the input/output module and the second identification code is recorded.
In one or more embodiments of the present description, the identification information may be a CPU global unique ID of the input/output module.
In one or more embodiments of the present description, generating the second identification code according to the target configuration information and the identification information may include:
generating a first hash value of the target configuration information through a preset hash algorithm; for example, a HASH value (which is an example of a first HASH value) is generated for the target configuration information by a secure HASH algorithm; and forming the second identification code by the first hash value and the identification information. For example, the first hash value may be concatenated with the CPU global unique ID of the input/output module to obtain a character string, and the character string may be used as the second identification code, where the first hash value may be preceded or the CPU global unique ID of the input/output module may be preceded when the first hash value and the CPU global unique ID of the input/output module are concatenated, and the positions of the first hash value and the CPU global unique ID of the input/output module are not limited.
One or more embodiments of the present specification further provide another method for replacing a configurable input/output module, the method being executable by an input/output module, and fig. 2 is a flowchart illustrating a method for replacing a configurable input/output module according to one or more embodiments of the present specification, as shown in fig. 2, the method comprising:
step 201: generating a first identification code according to the configuration information of the input/output module and the identification information of the input/output module, wherein the first identification code is used for identifying the input/output module;
optionally, the configuration information of the input/output module in step 201 may be configuration information stored in the input/output module.
The manner of generating the first identification code according to the configuration information of the input/output module and the identification information of the input/output module is consistent with the manner of generating the second identification code by the main controller according to the configuration information of the input/output module and the identification information of the input/output module, and details are not repeated here.
Step 202: receiving a request message for reading an identification code sent by a main controller;
wherein, the request message of the identification code is used for requesting to acquire the first identification code of the input/output module.
Step 203: and sending the first identification code to the main controller.
In the method for replacing a configurable input/output module according to one or more embodiments of the present disclosure, after receiving a request message of an identification code of a host controller, an input/output module sends a first identification code generated in advance according to its own identification information and its own configuration information to the host controller, so that the host controller can compare the first identification code with a second identification code generated in advance based on the configuration information of the input/output module and the identification information, and when the first identification code and the second identification code are consistent, it can be determined that the input/output module is not changed, otherwise, it can be determined that the input/output module is changed, so that the host controller can know a change condition of the input/output module managed by the host controller in real time. For example, after the configurable input/output module is replaced on site by the user, the main controller can compare the first identification code acquired from the input/output module with the pre-stored second identification code, and immediately synchronize the configuration information of the input/output module to the input/output module if the first identification code and the second identification code are not consistent. So that the input/output module can automatically synchronize the module configuration information without manual intervention.
According to one or more embodiments of the present disclosure, the method for replacing a configurable input/output module may further include:
after a first identification code generated in advance is sent to the main controller, target configuration information sent by the main controller is received, the target configuration information is updated to the configuration information of the input/output module, the updated first identification code is generated according to the target configuration information and the identification information, and the input/output module is identified by the updated first identification code. After the updated first identification code is generated, when the input/output module acquires an identification code acquisition request sent by the main controller, the updated first identification code is sent to the main controller, and correspondingly, after the main controller receives the updated first identification code, the identification code is compared with a prestored second identification code to determine whether the input/output module is changed.
In one or more embodiments of the present description, generating the first identification code according to the configuration information of the input/output module and the identification information of the input/output module may include: generating a second hash value of the configuration information through a preset hash algorithm; and forming the first identification code by the second hash value and the identification information. It should be noted that, when the input/output module generates the first identification code and the main controller generates the second identification code, the used preset hash algorithm is the same, and the main controller can inform the input/output module of the preset hash algorithm by configuring information for the input/output module.
The operations performed by the main controller and the i/o module in the method for replacing the configurable i/o module are described above. In order to clearly illustrate the information interaction between the controller and the input/output module in the method, the method is further described below by way of an example.
As shown in fig. 3, in this example, the method of replacing the configurable input/output module may include the following processes:
the main controller receives target configuration information of a user on an A module (which is an example of the input/output module);
the main controller generates a HASH value by using a secure HASH algorithm according to the target configuration information of the module A by the user;
the main controller asks the module A for the CPU global unique ID of the module, and the ID and the generated HASH form a character sequence;
the main controller sends the target configuration information to the module a (it should be noted that the main controller may send the target configuration information to the module a after acquiring the target configuration information of the module a by the user, or may send the target configuration information to the module a after generating the identification code based on the target configuration information, where this embodiment does not limit the timing for the main controller to execute this step);
the module A uses the same secure HASH algorithm to generate a HASH value for target configuration information, and forms a character sequence with the CPU global unique ID of the module A;
when the main controller normally operates, the main controller periodically sends (for example, immediately sends when the main controller is powered on) an information frame requesting the identification code of the module a to the module a, and the module a responds to the information and sends the identification code of the module a to the main controller;
and the main controller compares whether the received identification code is consistent with the identification code of the module A stored in advance by the main controller, if so, the module A is considered to be unchanged, the target configuration information is not sent to the module A, and if not, the target configuration information is immediately sent to the module A.
