# CreateMsg

### int CreateMsg(short nStream, short nFunction, short nWbit)

새로운 SECS 메시지 객체를 생성합니다. `SnFnW` 형식(Stream, Function, Wait bit)을 지정하여 메시지 작성을 시작하며, 성공 시 해당 메시지를 핸들링할 수 있는 고유 Message ID를 반환합니다.

Parameters

<table data-header-hidden><thead><tr><th width="200"></th><th width="149"></th><th></th></tr></thead><tbody><tr><td><strong>Name</strong></td><td><strong>Type</strong></td><td><strong>Description</strong></td></tr><tr><td>nStream</td><td>short</td><td>메시지의 Stream 번호 (Sn)</td></tr><tr><td>nFunction</td><td>short</td><td>메시지의 Function 번호 (Fn)</td></tr><tr><td>nWbit</td><td>short</td><td>Wait Bit 설정 (1: 응답 대기, 0: 응답 불필요)</td></tr></tbody></table>

```csharp
// 예: S1F1 (Are You There?) 메시지 생성 (Wait Bit = 1)
short stream = 1;
short function = 1;
short wBit = 1;
string strMODELNAME = "Model_1",strSOFTREV = "V.14.1.2";

int lMsgId = m_gem.CreateMsg(stream, function, wBit);
m_gem.OpenListItem(lMsgId);
m_gem.AddAsciiItem(lMsgId, strMODELNAME, strMODELNAME.Length);
m_gem.AddAsciiItem(lMsgId, strSOFTREV, strSOFTREV.Length);
m_gem.CloseListItem(lMsgId);
m_gem.SendMsg(lMsgId);
