I want to use the values from scaling on a tag - in an expression.

<M251_simulator\Modbus_Driver\SensorNivå1\"Scaled Min">] / 20 * 5

or rather something like this:

[*Numeric\"Scaled Min"] / 20 * 5

This is not working. Gives an error.

What am I doing wrong.

The format to get properties of a tag is [MyTagName]\PropertyName.

Just using [MyTagName], by default, returns the value property - the equivalent of [MyTagName]\Value.

You would need to do -

[<M251_simulator\Modbus_Driver\SensorNivå1>]\Scaled Min / 20 * 5


[*Numeric]\ScaledMin

Note that not all properties of tags are publicly exposed to be used in an expression.

Thanks!
