    Default Multiple binary inputs to analogue value

    Can anyone give some thoughts on the best way to take multiple single binary inputs and convert them to an analogue value?

    We have a tap changer which gives us discrete binary output for each tap position (eg 1 to 10). I'm looking to display this onscreen as a numberical value. What is the most efficent way to program this? I could create a combined element and use formula there is to display seperate images with a number in it for each input, but I'm thinking there may be a better way to do this (perhaps use a formula to convert to an analogue value whcih can then be displayed easily on screen). IS there a way I can combine multiple binaries together to create a single value (and can then use reaction matrix 'bits'?

    Thanks.

    I would make a solution using zenon Logic.
    You may create a Logic project (to run on network servers) and use the values of these binary inputs to calculate the value of additional, integer variable - of stratonNG driver.

    Steps:
    1. create a Logic project, configure the binary input variables 'externally visible', in Logic create fieldbus driver 'Logic to SCADA connection'; cycle > 100ms
    2. create variable in stratonNG, e.g. "tap_position"
    3. ST-language code to calculate value:
    tap_position.0 := variable_binary_input1;
    tap_position.1 := variable_binary_input2;
    ...

    Ursula,

    Thanks for the reply.. I will certainly give that a try, although I was hoping there would be way to do this without using Zenon Logic... in the editor only. Is there at least a way within Logic where I can create a 'template' logic and have it apply to all variables with a specifc naming convertion (eg ending _TAP01, TAP02 etc)?

    Cheers.

    You could do this using a sub-program.
    In zenon Logic, right-click in your project-list > Insert new program > Choose a name, the programming language can be ST, and think to check Execution-style = Sub-program

    As inputs, your binary values. As an output, the values converted to an analog one.



    Then in the sub-program, as Ursula said:

       tap_pos.0 := bi_1;
       tap_pos.1 := bi_2;
       ...


    Finally in your main program you just have to use your sub-program multiple times.

       tap_position_TAP01 := My_SP( variable_binary_input1, variable_binary_input2, variable_binary_input3, ...);
       tap_position_TAP02 := My_SP( variable_binary_input10, variable_binary_input11, variable_binary_input12, ...);
       ...


    Cheers,
    Anthony
