HslCommunication.Profinet.Siemens 命名空间

Contains the methods to convert between DateTime and S7 representation of datetime values.

使用了Fetch/Write协议来和西门子进行通讯，该种方法需要在PLC侧进行一些配置
Using the Fetch/write protocol to communicate with Siemens, this method requires some configuration on the PLC side

西门子的Fetch/Write协议的虚拟PLC，可以用来调试通讯，也可以实现一个虚拟的PLC功能，从而开发一套带虚拟环境的上位机系统，可以用来演示，测试。
The virtual PLC of Siemens Fetch/Write protocol can be used for debugging communication, and can also realize a virtual PLC function, so as to develop a set of upper computer system with virtual environment, which can be used for demonstration and testing.

西门子的MPI协议信息，注意：未测试通过，无法使用
Siemens MPI protocol information, note: it has not passed the test and cannot be used

西门子的PPI协议，适用于s7-200plc，注意，由于本类库的每次通讯分成2次操作，内部增加了一个同步锁，所以单次通信时间比较久，另外，地址支持携带站号，例如：s=2;M100
Siemens' PPI protocol is suitable for s7-200plc. Note that since each communication of this class library is divided into two operations, and a synchronization lock is added inside, the single communication time is relatively long. In addition, the address supports carrying the station number, for example : S=2;M100

PPIServer的虚拟服务器对象，支持的地址类型和S7虚拟服务器一致

一个西门子的客户端类，使用S7协议来进行数据交互，对于s300,s400需要关注Slot和Rack的设置值， 对于s200，需要关注LocalTSAP和DestTSAP的设置值，详细参考demo的设置。
A Siemens client class uses the S7 protocol for data exchange. For s300 and s400, you need to pay attention to the setting values of Slot and Rack. For s200, you need to pay attention to Slot and Rack. See cref="LocalTSAP"/> and DestTSAP settings, please refer to the demo settings for details.

测试的基于S7 PLUS的协议，功能还未完成，无法调用

西门子S7协议的虚拟服务器，支持TCP协议，模拟的是1200的PLC进行通信，在客户端进行操作操作的时候，最好是选择1200的客户端对象进行通信。
The virtual server of Siemens S7 protocol supports TCP protocol. It simulates 1200 PLC for communication. When the client is operating, it is best to select the 1200 client object for communication.

西门子的基于WebApi协议读写数据对象，支持对PLC的标签进行读取，适用于1500系列，该数据标签需要共享开放出来。
Siemens reads and writes data objects based on the WebApi protocol, supports reading PLC tags, and is suitable for the 1500 series. The data tags need to be shared and opened.
