+### API
+
+Python可以使用的`S7`其实是一个`IS7ServerService`接口对象：
+
+```C#
+public interface IS7ServerService
+{
+	bool ReadBit(int dbNumber, int offset, byte bit);
+	void WriteBit(int dbNumber, int offset, byte bit, bool flag);
+
+	byte ReadByte(int dbNumber, int pos);
+	void WriteByte(int dbNumber, int pos, byte value);
+
+	short ReadShort(int dbNumber, int pos);
+	void WriteShort(int dbNumber, int pos, short value);
+
+	uint ReadUInt32(int dbNumber, int pos);
+	void WriteUInt32(int dbNumber, int pos, uint value);
+
+	ulong ReadULong(int dbNumber, int pos);
+	void WriteULong(int dbNumber, int pos, ulong value);
+
+	float ReadReal(int dbNumber, int pos);
+	void WriteReal(int dbNumber, int pos, float real);
+
+	string ReadString(int dbNumber, int offset);
+	void WriteString(int dbNumber, int offset, int maxlen, string str);
+	Task StartServerAsync();
+	Task StopServerAsync();
+}
