==== Full Name ====

Lib.Mervis.v1_0.ScadaAnimation

==== Required Project References ====

  * Lib.Mervis

===== Description =====

An auxiliary block used for generating state numbers for the animation of operation and alarm for SCADA.

===== Usage in ST =====

<code>
program test
    var
        inp: lib.mervis.v1_0.ScadaAnimation;
    end_var

    inp();
end_program
</code>

===== Inputs =====

|Name              |Data Type|Retain|Must Connect                                                                         |Meaning|
|CompositeState    |uint     |No    |Yes   |Composite state, see for example [[SwitcherBlock_v1.2.htm|SwitcherBlock v1.2 - Composite state]]|      |
|UseFeedbackForRun |bool     |No    |No    |Determines whether the run state is taken from the feedback value (=true) or command value (=false)|      |


===== Outputs =====

|Name        |Data Type                                                                                                                                                                                                                                                                                                                                                                                                                      |Meaning|
|StateNumber |int      |State number according to CompositeState. If there are multiple states, they change sequentially with a period of one second. Each state has its priority. If the input satisfies multiple states, the output is the one with higher priority (e.g., the technology reports a fault but is in operation)\\ \\ |Number              |Priority|Meaning |\\ |0                  |1       |Off    |\\ |1 -> 2 -> 3 -> 1...|2       |Running|\\ |4 -> 5 -> 4...     |3       |Fault  ||      |


===== Detailed Function Description =====

The block is used for animating the state of a controlled element. It cyclically changes the state number, thus allowing the assignment of individual animation phases. A typical use is with Weintek HMI displays.
