    I copies this from the SCADA documentation as below:-
    An input channel formula that does not contain “;” (semicolon) symbol calculates the input channel value only.
    If an input channel formula contains “;”, the formula calculates the input channel value and status. The first part before semicolon is a formula for value calculation and the second part after semicolon calculates status.

    But I still do not understand this point. Can you kindly help to explain with an example if possible? There is a confusion between value and status using semicolon here. Thanks for your further clarification on this.

    Channel data contains value and status. If you open archive data using the Administrator app you can see that.
    A formula can calculate channel value and status separately. Semicolon splits formula into 2 parts. 1st for calculating value, 2nd for calculating status.
