Detailed Description

The present invention will be further described in detail with reference to the following examples, in order to make the objects, technical solutions and advantages of the present invention more apparent.

Currently, fieldbus networks have been widely used in industrial automation processes. In some fieldbus networks, a master station and a slave station may be included. A master station may be connected to one or more slave stations via a fieldbus. The secondary stations may generally be field devices that participate in performing industrial automation processes, while the primary station may monitor and control the secondary stations.

Various fieldbus protocols have been developed, such as the Actuator-Sensor-Interface (ASI) bus protocol. The ASI bus network may be an underlying network in a fieldbus system. In an ASI bus network, an ASI master station and an ASI slave station are typically included. An ASI master station may be understood as a master unit in an ASI bus network, which is mainly used for controlling and managing connected ASI slaves. ASI slaves may typically include various types of modules such as input/output (I/O) modules (in which case the I/O modules may further connect to sensors, actuators, etc.), security modules (such as switching devices, sensors, actuators, etc.), and other application modules, etc.

Since the status of a secondary station is closely related to the normal operation of an industrial automation process, field personnel often need to monitor the status of the secondary station in order to, for example, discover anomalies or faults of the secondary station in time, etc. Therefore, the embodiment of the invention provides a technical scheme for processing the information of the secondary station, which can realize the efficient monitoring of the secondary station on site, not only effectively save the labor cost of site personnel, but also ensure the normal operation of the industrial automation process.

Embodiments of the present invention may be applied to a variety of applicable fieldbus networks, such as the ASI bus networks described above, but embodiments of the present invention are not limited thereto.

In the example of fig. 1, the master station 102 may be connected to a plurality of slave stations, such as slave stations 104-1, 104-2 through 104-N. Typically, the master station 102 may be coupled with the slave stations 104-1, 104-2 through 104-N via a Fieldbus. For example, in an ASI bus network, the master 102 may be connected to the slaves 104-1, 104-2 to 104-N via an ASI bus, in which case the master 102 may be an ASI master and the slaves 104-1, 104-2 to 104-N may be ASI slaves. It should be understood that the number of individual devices shown herein is for ease of illustration only and is not intended to limit the scope of the present invention in any way.

In addition, the master station 102 may also be in communication with a controller 106. The controller 106 may perform control and processing functions such as the master station 102 may transmit data from the slave stations 104-1, 104-2 through 104-N to the controller 106, which may be processed, diagnosed, etc. by the controller 106. In some cases, the controller 106 may also send an execution command to the master station 102 for one or more slave stations, and the master station 102 may send corresponding commands to the slave stations, causing the slave stations to perform corresponding actions.

In embodiments herein, the controller 106 may be a variety of suitable devices having processing functionality, for example, the controller 106 may be implemented by a programmable logic controller (Programmable Logic Controller, PLC), a general purpose processor, an application specific integrated circuit, or the like.

The master station 102 and the controller 106 may also be connected via a fieldbus, such as a PROFINET bus or the like. Further, while the master station 102 and the controller 106 are shown as separate devices in the example of fig. 1, in some implementations the master station 102 and the controller 106 may be integrated together. The embodiments of the present invention are not limited in this regard.

Further, a device 108 is also shown in the example of fig. 1. The device 108 may be deployed on the same site as the slave stations 104-1, 104-2 through 104-N. The device 108 may have a display function. For example, the device 108 may be a device that includes a human-machine interface, such as may be implemented as a touch screen.

In the example of fig. 1, the controller 106 may be in communication with the device 108. For example, the controller 106 may be coupled to the device 108 via a field bus, such as a PROFINET bus or the like. As will be described further below, in embodiments of the invention, the device 108 may receive information from the controller 106 regarding the current state of one or more of the secondary stations 104-1, 104-2, through 104-N, and may then visually present a state indicator indicating the current state of the secondary stations 104-1, 104-2, through 104-N. This allows field personnel to intuitively and efficiently monitor the status of each secondary station deployed in the field.

The technical scheme of the invention will be further described below in connection with specific embodiments.

Fig. 2 is a schematic flow diagram of a method for processing secondary station information, according to some embodiments. The method of fig. 2 may be performed by a device deployed at the same site as a secondary station, such as device 108 in fig. 1.

In step 202, current state information of a secondary station may be received from a controller. The current state information may be used to indicate the current state of the secondary station.

In step 204, a target state indicator corresponding to the current state of the secondary station may be visually presented based on the current state information.

It can be seen that in embodiments of the present invention, a status indicator corresponding to the current status of a secondary station is visually presented by a device deployed on the same site as the secondary station, so that a field person can intuitively and explicitly determine the status of the secondary station, such as in the event of an anomaly or failure of the secondary station, and can timely discover and maintain. Therefore, the labor cost of the on-site personnel management slave station can be greatly saved, and the management efficiency is improved.

In some embodiments, prior to step 204, a target state indicator corresponding to the current state of the secondary station may be determined among the plurality of state indicators based on the current state information and the preset correspondence information. The preset correspondence information may represent a preset correspondence relationship between the plurality of kinds of state information and the plurality of kinds of state indicators. For example, a status information may correspond to a status indicator. In this way, a target state indicator corresponding to the current state information can be selected from among a plurality of state indicators.

The various status indicators may be visually distinguishable from one another, which facilitates the field personnel to intuitively and unequivocally determine the status of the secondary station. For example, in some embodiments, the plurality of status indicators may each have a visual characteristic that is visually distinguishable, such as a different color, shape, symbol, pattern, etc., which is not limited herein.

In some embodiments, in step 204, the identity of the secondary station and a target status indicator corresponding to the current status of the secondary station may be presented in an associated manner. For example, the identity of the secondary station may be presented with a target status indicator, such as above, to the left, to the right, below, etc., the identity of the secondary station. In this way, it is easy to know directly and clearly which secondary station the status indicator corresponds to.

In some embodiments, there may be multiple secondary stations (including those described above) deployed on the same site as the device. In this case, the status indicators corresponding to the current status of each of the secondary stations may be presented visually at the same time. In particular, status indicators corresponding to individual secondary stations deployed in the field may be visually presented, and in addition, the identity of the individual secondary stations may also be presented together. In this way, it is convenient for field personnel to efficiently monitor the status of various secondary stations on the field.

Fig. 3 is a schematic flow chart of a method for processing secondary station information according to some embodiments. The method of fig. 3 may be performed by a controller, such as controller 106 in fig. 1.

In step 302, current status data reported by the secondary station may be acquired.

For example, in the example of fig. 1, the master station 102 may receive current state data from the slave station 104-1. The master station 102 may then send the current status data to the controller 106.

In step 304, the current state data may be processed to determine the current state information of the secondary station. The current state information may be used to indicate the current state of the secondary station and have a format that can be used by devices deployed on the same site as the secondary station.

In general, the current state data of the secondary station may be some raw measurement data and thus needs to be processed together to determine the current state information of the secondary station so that the current state information has a format that can be used by devices deployed in the same site as the secondary station.

In step 306, current status information of the secondary station may be transmitted to the device so that the device visually presents a target status indicator corresponding to the current status of the secondary station.

It can be seen that in an embodiment of the present invention, the current state information indicating the current state of the secondary station is obtained by processing the current state data reported by the secondary station, and has a format that can be used by a device disposed on the same site as the secondary station, so that the device can visually present a target state indicator corresponding to the current state of the secondary station based on the current state information. Thus, the field personnel can intuitively and clearly judge the state of the secondary station, and can timely find and maintain the state in case of abnormality or failure of the secondary station. Therefore, the labor cost of the on-site personnel management slave station can be greatly saved, and the management efficiency is improved.

In some embodiments, in step 302, current status data reported by a secondary station may be received from a primary station. For example, in the context of an ASI bus network, a master station and a slave station may be connected via an ASI bus. The master station may receive current status data of the slave station via the ASI bus. The master station may then send the current status data to the controller.

In some embodiments, the current state data may include values of a plurality of state bits. In this case, in step 304, the values of the plurality of status bits may be combined in a preset order, thereby obtaining current status information. For example, each status bit may have a binary value of 0 or 1. Then, the values of the status bits are combined in a preset order to obtain a decimal value. In this case, the current state information may include the decimal value.

In some embodiments, the plurality of status bits may include a first status bit, a second status bit, and a third status bit. The first status bit may indicate whether it is configured and detected on the Fieldbus, the second status bit may indicate whether it is detected but not configured on the Fieldbus, and the third status bit may indicate whether it is configured but not detected on the Fieldbus. For example, the value of each status bit may be 0 or 1, thereby indicating the corresponding status. In this context, configuration may mean that the secondary station parameters are set or configured in configuration software for the industrial automation process.

Accordingly, based on the three status bits, a variety of status information may be determined. For example, each state information may be used to indicate one of the first state, the second state, the third state, and the fourth state. The first state may represent configured and detected on the fieldbus, that is to say that the slave station is in a normal state. The second state may indicate that it is configured but not detected on the fieldbus, i.e. that the secondary station has been configured by the configuration software but is not actually connected to the fieldbus. The third state may indicate that it is detected on the fieldbus but not configured, i.e. that the slave is not configured by the configuration software but is actually connected to the fieldbus. The fourth state may indicate that it is not configured and not detected on the fieldbus, that is, that no secondary station is found on both the configuration software and the fieldbus.

As previously described, each type of status information may correspond to a type of status indicator such that devices deployed on the same site as the secondary station may present the corresponding status indicator based on the current status information of the secondary station.

For ease of understanding, the following description will be made in connection with specific examples. The following description is still made in connection with the exemplary scenario of fig. 1, and in addition, in the following example, it is assumed that the example of fig. 1 is an ASI bus network scenario. However, it should be understood that these examples do not limit the scope of the invention.

Fig. 4A is a schematic flow chart of a process for processing secondary station information according to some embodiments. In the example of fig. 4A, the secondary station 104-1 is described as an example. The procedure is similar for other secondary stations and will not be described in detail.

As previously described, assuming that the scenario of fig. 1 is an ASI bus network scenario, master 102 may be an ASI master and slave 104-1 may be an ASI slave.

In step 402, the secondary station 104-1 may transmit current state data to the primary station 102.

In the ASI bus network scenario, the current state data may include the values of three state bits. For example, the three status bits may be LPS (List of Projected Slaves) status bits, an LDS (List of DETECTED SLAVES) status bit, and an LAS (List of ACTIVATED SLAVES) status bit, respectively. The LPS status bit may indicate whether it is configured but not detected on the ASI bus. The LDS status bit may indicate whether it is detected on the ASI bus but not configured. The LAS state bit may indicate whether it is configured and detected on the ASI bus. The LPS state bit, LDS state bit, and LAS state bit have binary values of 0 or 1.

In step 404, the master 102 may transmit current state data of the slave 104-1 to the controller 106, such as transmitting respective values of the LPS state bit, the LDS state bit, and the LAS state bit to the controller 106.

In step 406, the controller 106 may process the values of the three status bits to obtain the current status information of the secondary station 104-1.

The controller 106 may combine the values of the three status bits in a preset order to obtain the current status information. For example, the controller 106 may divide a separate memory area to store the values of three status bits, such as the memory area may be one byte in size. The controller 106 may write the value of the LAS status bit to the 0 bit of the byte, the value of the LDS status bit to the 1 bit of the byte, and the value of the LPS status bit to the 2 bits of the byte. Fig. 4B illustrates an example of a storage area for storing a value of a status bit. As shown in fig. 4B, the memory region may be denoted as M100, where M100.0 may store the value of the LAS state bit, M100.1 may store the value of the LDS state bit, and M100.2 may store the value of the LPS state bit.

When the values of the LPS state bit, LDS state bit, and LAS state bit are all 1, the binary values 111, namely the decimal value 7, can be obtained by combining in the above order. In this case, the status information may include a decimal value of 7, which may indicate that the slave station is in a normal state, i.e., configured and detected on the ASI bus.

When the value of the LPS status bit is 0, the value of the LDS status bit is 1, and the value of the LAS status bit is 0, a binary value 010, namely a decimal value 2, can be obtained. In this case, the status information may include a decimal value of 2, which may indicate that the slave station is detected on the ASI bus, but not configured.

When the value of the LPS status bit is 1, the value of the LAS status bit is 0, and the value of the LDS status bit is 0, a binary value of 100, namely a decimal value of 4, may be obtained. In this case, the status information may include a decimal value of 4, which may indicate that the secondary station is configured but not detected on the ASI bus.

When the value of the LPS status bit is 0, the value of the LAS status bit is 0, and the value of the LDS status bit is 0, a binary value of 000, namely, a decimal value of 0, may be obtained. In this case, the status information may include a decimal value of 0, which may indicate that the secondary station is not configured and not detected on the ASI bus, i.e. that the secondary station is not present.

In step 408, the controller 106 may send the current status information of the secondary station 104-1 to the device 108. As previously described, the current state information may include decimal values.

In step 410, the device 108 may visually present a status indicator corresponding to the current status of the secondary station 104-1 based on the current status information and the preset correspondence information.

The preset correspondence information may include a preset correspondence relationship between the state information and the state indicator. Following the above example, assume that the status indicator is represented by a circle having a color. The settings may be as follows: a value of 2 corresponds to a yellow circle indicator, a value of 4 corresponds to a red circle indicator, a value of 7 corresponds to a green circle indicator, and a value of 0 corresponds to a gray circle indicator. Fig. 4C shows a schematic diagram of one example of preset correspondence information. As shown in FIG. 4C, column 420 may represent different decimal values and column 430 may represent status indicators corresponding to the different decimal values.

In this way, based on the decimal value included in the current state information, the device 108 may present a state indicator corresponding to the decimal value.

Of course, for other secondary stations, such as secondary stations 104-2 through 104-N, the process is similar to that described above. Thus, the device 108 may visually present the status indicators corresponding to the slave stations 104-1 through 104-N. For example, fig. 4D shows a simplified schematic diagram of status indicators for various secondary stations presented on device 108. In the example of fig. 4D, the identities of the secondary stations and their corresponding status indicators are presented together, thus enabling field personnel to intuitively monitor the status of each secondary station. In the example of fig. 4D, assuming that the slave station 104-1 is in a normal state, the slave station 104-2 is in a configured but not detected on the ASI bus, and the slave station 104-N is in a detected but not configured state on the ASI bus.
