Now, the screen will update its values to the correct tags as the user shifts between the different stations and devices.
Once that expression is set up, we can implement an indirect tag for the float IO field.
The next step is to create a property binding on that string parameter so that it accesses the FloatName column that has been configured on the Device Selector dropdown. A screen’s custom properties can be accessed by right-clicking the screen and selecting the Custom Properties item under the Customizers menu. The first step to achieving this is to create a string custom property on the screen that will hold the tag path for our float IO field. Fortunately, with a few extra steps, we can still use that value to point the float input/output field to the correct tag in our tag browser. The only difference between the two being that I replaced Double with Int.Īs unfortunate as it is, we cannot use indirect tagging to access the custom column that we added to the device selector. An almost identical indirect tag expression can be used to set the integer field to the correct tag. In this dynamic mapping, the tag-path is automatically set to the correct double by taking the selected value of the station and device selectors. The Device Selector dataset can be set up in a very similar fashion to the Station Selector with the biggest difference being that it needs to have an extra column added to account for the float values' tag-paths.Īfter the dropdown lists were configured, I used indirect tag bindings to map the selected integers and double values to their respective IO fields. The second dropdown list is used to select a device within that station. One of the dropdown lists is used to set the selected station (see figure 1 for the dataset configuration and figure 2 for the tag structure). In this example, I set up a calibration screen with two dropdown lists. For example, Device 1 would correspond to Int1, Double1, and SmallFloat ( Devices 1 and 2 share SmallFloat, while 3 and 4 share BigFloat). If each station has four devices, then each will have its own integer and double value with two devices sharing a float value. In the above tag structure, each station has many sub-devices with the same underlying tag structure. Since the value and label are independent from each other, the developer can use any label they want (such as a number or a relative position) to convey the station’s identity to the user.

For example, in situations where the system has individual stations that use similar equipment, it is likely that the only thing differentiating these units from a software perspective would be the number assigned to that station. This is useful because a more detailed description is displayed to the user while something as simple as an integer can be set to a parameter in the background. The dropdown list comes with a built-in, two-column dataset where one column displays a label and the other corresponds to a selected value. One object that can be very useful and intuitive to implement is the dropdown list component.

This blog will explore how to create a screen that allows the user to navigate easily between configuration settings for similar devices. Some of these features are custom screen properties, parameterized templates, and expression building.
Ignition has many powerful and useful features that can be utilized for making screens with dynamic animations and control. Ignition can run on a variety of platforms and interfaces easily with many field IO devices using its built-in drivers. Ignition is a versatile SCADA platform from Inductive Automation that is quickly becoming one of the top choices for industrial automation solutions.
