====== CFHEADER library 설치 및 프로젝트 만들기 ======
[[https://www.comfilewiki.co.kr/ko/doku.php?id=cfnet:cfheaderdevelopmentenvironment:index|개발PC 환경 설정]]을 마쳤다면,
Visual Studio를 이용하여 프로그램(App)를 만드는 방법과 CFHEADER library(Nuget Packages) 설치 방법을 설명합니다.
  - [[:fieldio:cfnet:cfheadernewproject:newproject|프로젝트 만들기]]
  - [[:fieldio:cfnet:cfheadernewproject:library|프로젝트에 CFHEADER library 설치 (Nuget Packages) ]]

위 설정을 마쳤다면 아래의 예제 코드로 동작을 확인할 수 있습니다. **( CFHEADER [**//ADDR. 0//**] + CFDO-16N [**//ADDR. 0//**] )**

<code csharp>
using ComfileTech.Cfnet.Cfheader;

var cfheader0 = Cfheader.Instances[0];
var digitalOutputModule0 = cfheader0.DigitalOutputModules[0];

cfheader0.Open();

while (true)
{
    // Blink each output in increasing order
    foreach (var channel in digitalOutputModule0.Channels)
    {
        channel.Blink();
    }

    // Blink each output in decreasing order
    foreach (var channel in digitalOutputModule0.Channels.Reverse())
    {
        channel.Blink();
    }
}

static class Extensions
{
    public static void Blink(this DigitalOutputModule.Channel channel)
    {
        // Toggle the channel's state
        channel.Toggle();

        // Delay for 50ms
        Thread.Sleep(50);

        // Toggle the channel's state again
        channel.Toggle();
    }

    public static void Toggle(this DigitalOutputModule.Channel channel)
    {
        // Toggle state
        channel.State = !channel.State;

        // Write the state to the module
        channel.Module.Header.Sync();
    }
}

=====예제 프로그램 2=====

아래 예는 여러 개의 CFHEADER모듈 사용 프로그램입니다. **[ CFHEADER[0, 1, 2] x CFDO[0, 0, 0] ]**
