Operator Terminal Expert : Index 0 DropDown List

[rfond]

Hello everyone,

I have another issue with EOTE. I have a selectable dropdown list, and I want to use index 0 from this list (my selection options are 0 = Stop / 1 = Auto / 2 = Manual). The problem is that the index always starts at 1. This is a big issue for me.

How can I use index 0?

Thanks!

Hi unfortunately there is no way the dropdown object to start with index 0. If this is on a faceplate (popup) you can probably add an additional 'Accept/Ok' button to write the (selected index - 1) to the PLC variable. Convertors will also not work as it can only convert direction PLC -> HMI and not the other way around.

Are any fixes planned for this version?
Is there a roadmap for EOTE's future development?

EOTE is the software that will be used going forward on all new HMI models. It is active product and regular updates are released.

So can a fix be implemented for this issue?

Hi,

You can use convertor function with variable of item. I shared document at attached and shared  sample program that it made different method. You can reach to sample program via this link.

But the variable's direction is "One Way" :(.

I've already tried this solution, but it doesn't work.

I’m currently working with Schneider’s Operator Terminal Expert (EOTE) as well, and although my reply is a bit delayed, I recently ran into the same issue.

My goal was to assign a value from 0 to 3 to a DINT variable in the PLC based on the selection from a dropdown list.

I initially tried using a converter, but binding the variable to the object didn’t work: it seemed to expect a Boolean.

What ended up working for me was writing an onClick script for the dropdown component that subtracts 1 from the selected index and assigns it to the variable.

Here’s an example:

onClick($GraphicObject.ModeDropDown, () => {
    LS_PmpGrp001_W.Mode.Value = ($GraphicObject.ModeDropDown.SelectedIndex -1);
});

Hope this helps someone else running into the same challenge.
