Data Model

Data model is description of the properties, status and other information of the device.

Model List​

Click the Model menu in the Develop Manage navigation item on the left column List When the model's most recent model config (JSON) import has abnormal errors, it will be displayed in the publish Status column of the list

Model Add​

Click the Add button to slide out the new form on the right Add Fill in Name, Model, Number of modules, Note and click OK to complete the save

  • Name: The name of the data model. You can choose a meaningful name.
  • Machine Type: data model machine type, usually the device model
  • Modules: One device corresponds to the number of acquisition terminals (HMI), for example: one screen and one machine is: 1, and so on, n screens and one machine is n
  • Notes: Notes on the data model for easy reference

JSON Import​

After the model parameters are successfully imported, the model will be automatically published

If the imported model is the same as the previous model, and the original parameters are not modified, the code table configuration and alarm configuration of the original parameters will be retained.

The JSON format is:

{
    "mk":"{mk}", "un":{un},
    "env": [
        {
            "code":"mach_sts", "name":"Running status", "unit":"",
            "type":"u16", "dp":0, "rw":"rw"
        },
        {
            "code":"{code}", "name":"{name}", "unit":"{unit}",
            "type":"{type}", "dp":{dp}, "rw":"{rw}"
        },
        // ...
    ],
    "run": [
        {
            "code":"{code}", "name":"{name}", "unit":"{unit}",
            "type":"{type}", "dp":{dp}
        },
        // ...
    ],
    "err": [
        {
            "code":"{code}", "desc":"{desc}"
        },
        // ...
    ]
}
  • env is the environment parameter, the parameter mach_sts (must be included in the main module), the rw parameter** can be ** r (read-only), w (write-only), rw (read and write), ww (double write)
  • run is the running parameter. In this environment, the rw parameter can only be r (read-only)
  • err is the exception parameter. In this environment, the rw parameter can only be r (read-only).
  • ⚠️Note
    • The parameter code can only be a combination of alphanumeric characters and underscores except the __diff suffix. The characters iot_sts, ts, dn, req, rid, root, time and timestamp are reserved words. Import is prohibited.
    • When there is no associated device under the model, repeated import is an overwrite operation
    • When the model has related devices, repeated import is accumulative operation. If the same parameter display type is different, the import will report an error. If display type is the same and storage type is different, it will report an error based on compatibility. For example: u32 can be changed to u16, but not vice versa.
    • When the model is multi-module (n screens one machine), the parameters between modules cannot be repeated and the extension module (not un0) cannot contain the parameter mach_sts

If an abnormal occurs after importing, it will be prompted on the Tab page. After the import is successful, the abnormal prompt disappears.

Click the Download button to download the model configuration. After modification, you can modify the parameters through JSON import

Operate​

Edit​

Click the Edit button in the parameter list
Environment parameters, Abnormal parameters You can edit Name, Unit

IxSet

  • Name: data model parameter name
  • Unit: Model parameter unit, such as temperature is °C

Running parameters You can also add Difference calculation

RunIxSet

  • Difference: The numeric type parameters in the running parameters can be used for difference calculation. After enabling, there will be an additional parameter ending with _diff. When calculating statistics, use this field for difference calculation. Reference Case

Code table​

Used to configure the data source of the component in DV. When the data source parameter has been configured in the code table in the object model, you can check the matching code table and select the indicator that needs to match the code table.

For example, add the parameter machine status (mach_sts) in the code table value: 1 content: power on, value: 0 content: power off. When the component in dv is configured with a data source that uses this parameter, check the matching code table and select this indicator (mach_sts). If the indicator is 1, it will automatically convert to power on. Similarly, 0 will automatically convert to power off.

Click the More button and click Code Table

Code

  • Value: As in the example 1->Power on, key is 1
  • Content: The value is the power on

Alarm​

Configure alarm rules to generate alarm information. Multiple alarm rules can be configured, and third-party applications can process their own business based on the alarm information.

Click the Alarm -> Add Alarm button to configure Alarm Level, Trigger Condition, Trigger Value, Alarm Message Code Code

  • Alarm level: Custom alarm level in the system, Serious > Primary > Warning
  • Trigger conditions and trigger values: For example, when the indoor temperature temp_inner condition is greater than (>) and the value is 30, an alarm message will be sent
  • Alarm message: The message sent when the alarm condition is triggered

  • Machine Type: Machine Type, usually the device model
  • Notes: Notes on the data model for easy reference
