Description

An embodiment of the present invention relates to an instrumentation monitoring device that monitors and controls each input / output contact in an instrumentation control system of a plant.

In the instrumentation monitoring device used in the instrumentation control system, the user searches for the tags set corresponding to each input / output contact of the equipment, devices, instruments, etc. provided in the plant by the tag name search function. Can be done. In such an instrumentation control system, it is possible to easily expand to a tag point screen that displays various data and the like related to the tag having the searched tag name.

The instrumentation control system has a tag grouping function that can register a plurality of tag names. The tag group screen that displays the tag group generated by the tag grouping function is often positioned on the upper screen of the tag point screen. On the tag point screen, one tag group including the tag name can be displayed by clicking a button or the like for displaying the upper screen.

However, when a tag having the searched tag name is registered in a plurality of tag groups, only a specific tag group screen may be displayed. The specific tag group screen displayed in such a case is preset and is often not the desired tag group screen. Therefore, the user may take a long time to find a desired tag group using the tag name as a clue.

(First Embodiment)
FIG. 1 is a block diagram illustrating an instrumentation control system including an instrumentation monitoring device.
The instrumentation monitoring device according to the present embodiment is used for an instrumentation control system for plants such as steel, non-ferrous metals, papermaking, petrochemicals, and pharmaceuticals. As shown in FIG. 1, the instrumentation monitoring device 1 is used by being connected to a general-purpose communication network 103 such as Ethernet (registered trademark). A data server 101, various engineering tools 102, a distributed control system (DCS) 105, and the like are connected to the communication network 103 to which the instrumentation monitoring device 1 is connected.

The DCS 105 is also provided with a network 106 to which various input / output contacts are linked. The DCS 105 is also connected to the control network 104. Although not shown, a plurality of other DCSs can be connected to the communication network 103 and the control system network 104, and a programmable logic controller (PLC) or the like can also be connected via a gateway. .. The DCS and PLC are connected to the input / output contacts in the process line by dedicated network links or the like. The instrumentation monitoring device 1 monitors the devices, devices, instruments, etc. to which the input / output contacts are connected based on the data of the input / output contacts, and also controls the devices, devices, instruments, etc. via the input / output contacts. can do.

In the instrumentation control system 100, tags corresponding to each input / output contact are set. Each tag is given a tag name and stored in the data server 101. The data server 101 associates the tag name with the current data (real-time data) and past data (historical data) of the contact point corresponding to the tag, the symbol data on the HMI screen corresponding to the tag, and the like as a database. It is stored.

The instrumentation monitoring device 1 calls various data and the like associated with the tag name by designating the tag name and the display type and the like on the HMI screen, and displays the data according to the display type. , The corresponding input / output contacts can be operated. The HMI screen generally refers to a screen displayed by the instrumentation monitoring device 1 for establishing an interface (Human Machine Interface) between the user and the system side. For example, by clicking the tag symbol displayed on the HMI screen with the mouse, the attributes of the tag, contact data, and the like can be displayed.

When the scale of the instrumentation control system 100 becomes large, or when there are many tags set in the device even if the scale is small, the entire monitored system is displayed, and the monitored system is displayed each time. Searching for and displaying the tag name reduces the work efficiency of the user. Therefore, the instrumentation monitoring device 1 has a tag grouping function for registering necessary tags as a group.

The tag grouping function is realized by associating the tag group name of the tag group to be registered with the tag name in the database stored in the data server 101.

The user can register a tag having a plurality of tag names by using the tag grouping function. Then, the user can call the necessary tag group and perform the work efficiently when performing tag monitoring, tag operation, or the like.

The tag group may have a limit on the number of tag names that can be registered (for example, 8 or 16), but it is possible to register tags with the same tag name in different tag groups. In the present embodiment, the user can extract a list of tag groups using the tag name as a clue and search for a desired tag group from the extracted tag groups.
