    Default Line color based on two variables

    Dear All,

    I am using zenon Supervisor v7.11.
    I am new in zenon Supervisor and that is why, I can not figure out, how I can change color of polyline base on values of two variables.
    I have device with two network ports. For each port, I got status variable, which is:
    • 0 when the port is not connected
    • 1 when the port is connected. The device are connected in ring.
    I want to change the color of polyline, when both ports of two neighbout devices are connected to each other (i.e. are in status 1).

    I need AND (&) operation between the variable values. I see that the combi element allows such functionality. The problem is that it will be not very suitable to put combi element between device symbol.

    Any ideas how I can achieve this functionality?

    Best regards,
    Svetozar Yolov

    I figure out how to do it. I am writing it for a gents, in my situation.
    I made a symbol with polyline, with a form which suits me. Next I use combi element and use the symbol created. Next I use formula in combi element with logical AND (&) between the tag of my interest. Add the statuses. When both variables are in 1, the conditions will be fulfilled and the color will be changed accordingly.

    You could also use a variable from the mathematics driver to calculate the AND logic between the two variables. Then you don't need the combined element.

    Thank you for you answer. I considered this opportunity.
    In my perspective, if you have got a lot of devices (let say 20 and more), the quantity of work, in case of math driver will be more and more work to support.
    I believe combi element is better!
