I have a tag UDT definition called Motor. This UDT has a custom parameter “Description”. Each time I create an instance of this UDT, I enter the motor description so that I can use it in alarm messages and such.
I also have a popup window, which is the motor control popup (e.g. status, start/stop, etc). This motor window has a custom property “TagPath”, where I specify the path to the tag so that I can call the same popup with multiple instances of the Motor tag.
At the top of the popup I’d like to display the description of the motor. I can create a label, and I’ve got access to the tag path, but I can’t find a way to use that tag path to obtain the value of the specified tag’s “Description” property.
I know I could pass a description string to the window when I open it, but again, I can pass a window property or a tag value, but I can’t find a way to pass a tag property.
Any help is appreciated!
[edit] while I play around, I’m sending a hard-coded string. It’s working, but when I’ve got the label’s text property bound to the Description property, I then can’t use HTML to wrap the text across multiple lines. So, once I have my motor description being passed in correctly, any ideas on how to force the label object to display it with HTML (or at least, across multiple lines)?
As for the html, just use an expression bound to the text property of the label like: "<html>" + {<your string type property>}
I don't bother with closing html tags anymore unless I need to limit the scope
You can also use the html tag or
to otherwise format text after a html tag for text alignment etc. in addition to the wrapping you get from the "conversion" to html, although it sounds like you might already be familiar with this.
if TagProperties.value is not None:
for Property in TagProperties.value:
if Property.getProperty().name == ‘Description’:
system.gui.getParentWindow(event).getComponentForPath(‘Root Container.Motor Description’).text = ‘’+Property.value
