Ignition Vision Slider - How to make slider change value as you sliding

Ignition
1

In FactoryTalk HMI, if you slide the slider, the value update as you sliding.
In Ignition Vision, if you slide the slider, the value does not update until you release the mouse.
Are there a way to allow the slider change the tag value as you slide it?
At least should have a feed back of the slider value itself.

  • Select the slider.
  • On the Vision Property Editor set
    Behavior | Defer Updates = false

When set it to fault, I got this error:
"Bad("Bad_InternalError: An internal error occurred as a result of a programming or configuration error.")"

4

When set it to fault, ...
false not 'fault'. How did you even do that?

I got this error:
Where did the editor show up?

Defer updates

I did the same, that when I got the error.
What tag do you use?
I am running AB PLC on the Emulator.
Tag value can be updated, just cannot slide and change value.
When set Defer Updates to False, it won't work.

Sorry for late reply, I got pulled to other things, too many projects going on at the same time.

I try it using a memory tag, it has not issue.
It does not work with a live tag.

  1. Are you running in Designer or in a browser?
  2. If running in Designer, can you modify the tag value in Tag Browser? (You may have forgotten to switch Designer to Read/Write mode.)
  3. Does it work on the live tag after you let go the slider?

When I use a derive tag, it does not get the error, but it does not change value as I sliding it.
When using a derive tag, Defer Updates setting does not make any different.

I can change value.
both on designer and vision client.
It only updates value when I release the mouse.
Maybe there is something to do with OPC update rate.

I got the same error on vision client and on designers

Perhaps review this information:
Tag Groups

Pay close attention to the parts about polling rates and optimistic writes.

Thanks:
I created a group called Sim, then set rate to 200. it works fine.
In the past I created every individual type of group, AI, DI and many other type for UDT, for simulation, I just import tag, forgot about the data group.
Thank you very much for reminding me.
