## Note: About Siemens PLC address
```
VB263、VW263、VD263中的B、W、D分别表示：byte型(8位)、word型(16位)、doubleword型(32位)。

When this component passes in the address, there is no need to carry the data type, just use the corresponding method to read the corresponding type, such as:
VB263       - client.ReadByte("V263")
VD263       - client.ReadFloat("V263")
VD263       - client.ReadInt32("V263")
DB108.DBW4  - client.ReadUInt16("DB108.4")
DB1.DBX0.0  - client.ReadBoolean("DB1.0.0")
DB1.DBD0    - client.ReadFloat("DB1.0")
```
|C# data type | smart200 | 1200/1500/300
|---|---|---
|bit | V1.0 | DB1.DBX1.0
|byte | VB1 | DB1.DBB1
|shor <br> ushort  | VW2 | DB1.DBW2
|int <br> uint <br> float | VD4 | DB1.DBD4

## SiemensClient best practices
```
1、When not to take the initiative to open
Siemens plc generally allows up to 8 long connections. So when the number of connections is not enough or when doing testing, do not take the initiative to open, so that the component will automatically open and close immediately.

2、When to take the initiative to open
When the number of long connections is enough, and you want to improve the read and write performance.

3、In addition to active Open connections, batch read and write can also greatly improve read and write performance.
//Batch read
Dictionary<string, DataTypeEnum> addresses = new Dictionary<string, DataTypeEnum>();
addresses.Add("DB4.24", DataTypeEnum.Float);
addresses.Add("DB1.434.0", DataTypeEnum.Bool);
addresses.Add("V4109", DataTypeEnum.Byte);
...
var result = client.BatchRead(addresses);

//Batch write
Dictionary<string, object> addresses = new Dictionary<string, object>();
addresses.Add("DB4.24", (float)1);
addresses.Add("DB4.0", (float)2);
addresses.Add("DB1.434.0", true);
...
var result = client.BatchWrite(addresses);

4、[Note] When writing data, you need to clarify the data type
client.Write("DB4.12", 9);          //What is written is of type int
client.Write("DB4.12", (float)9);   //What is written is a float type

5、SiemensClient is a thread safe class
Due to limited long PLC connections, SiemensClient is designed as a thread-safe class. You can set SiemensClient as a singleton, and use the instance of SiemensClient to read and write PLC between multiple threads.
```

## MitsubishiClient (Mitsubishi) read and write operations
```
//1、Instantiate the client-enter the correct IP and port
MitsubishiClient client = new MitsubishiClient(MitsubishiVersion.Qna_3E, "127.0.0.1",6000);

//2、Write operation

//3、Read operation
var value1 = client.ReadBoolean("M100").Value;
var value2 = client.ReadInt16("D200").Value;
var value3 = client.ReadInt32("D210").Value;

//4、If there is no active Open, it will automatically open and close the connection every time you read and write operations, which will greatly reduce the efficiency of reading and writing. So it is recommended to open and close manually.
