Modify emulation sensor variable since dashboard

Hello,
How can I modify the value of a sensor emulation variable since a dashboard?
I want that if I write a value of a variable, this value changes in my PLC, but I don´t know how reference the variable.

I am using an edit box in the dashboard and if I reference the variable like this, It does not work.

I tried to reference it from the tree but it did not work either.

Thanks in advance.

Software Version:

FlexSim 22.1.3

You cannot link to the variable value directly because it is stored as part of an sdt-node (SimpleDataType) and not as a value of a separate node.

You can still use the edit field to update the variable, but there will be not direct link between the field and the value. So if the value gets changed by another part of the simulation, this change will not be reflected by in the edit field. Not sure if this is the only way to do it, but this is how we managed sensor variables when we experimented with emulation some time ago (similar anyway).

If the sensor variable does not have an "Associated Object" yet, add a dummy object (for example a plane or BasicFR) and connect it to the variable.

Then link the dashboard edit field to that object as well and send a message to it in the "On Apply" trigger, with the first message parameter containing the value of the edit field.

You can use this message being send as a "Write Event" for the sensor variable, setting the value to that of the first message parameter.
