Tag Detail

A tag’s detail page gives you access to all a tag’s information and actions. Below we will go into further detail about what each tab and section means.

General Tab

Status Banner

The status banner is located at the top of the general section. This is your key indication of the state of the tag. The banner will change colors and give the current status text as well as a detailed error message upon a tag failure.

The status bar can also be clicked to give a shortcut to the control popup.

Live Data

Below the tag’s status bar is the live data section. This will appear when the tag is enabled, and give a critical view of the tag’s realtime information such as latest value, the time of the last update, and the quality of the data.

General Settings

Next, the general settings section overview settings that are not unique to any particular protocol. At the bottom of general settings, is a link to update these general settings along with the name and description of the tag.

Quick Trend

At the bottom of the tag detail page is the Quick Trend section. This gives a convenient way to quickly view historical data from the long term database.

In the upper right corner you can select the period, or use the dropdown menu for additional quick trend features:

  • Easy way to add this tag to a system level trend.

Protocol Specific Tab

The second tab will dynamically update based on which protocol this tag is using. For example, if a tag is an OPC-UA tag, the tab will be named “OPC-UA” and you will be shown a list of OPC-UA Settings as shown below. Clicking the link at the bottom of this section will take you to a protocol specific form to update this tag’s settings.

For a more detailed explantation of protocol specific parameters, go to the pages under the Creating a Tag subfolder.

Some protocols offer an easy way to test a tag read from the device using the current configured settings. At the top of the protocol specific tab, you will see a bar that says “Click here to test”. Clicking this will attempt a read and return the results as shown below.
