PCD2.M48X 数字量输入模块 SAIA
PCD2.M48X 特点：
→具有TCP Server、TCP Client、UDP、虚拟串口、点对点连接等五种操作模式；
→用户基于网络软件，不需要做任何修改就可以与C2000 E210通讯；
→通过安装我们免费提供的虚拟串口软件，用户基于串口的软件不需要做任何修改就可以与C2000 E210通讯；
→对于需要开发软件的用户，我们免费提供通讯动态库、设置动态库或OCX控件；
→通过浏览器、设置软件或设置动态库进行参数设置；
→支持DNS域名解析功能；
→低消耗设计，无需散热装置；
→看门狗设计，稳定性高。
工作模式：
1．作为TCP服务器，转换器上电后在的TCP 端口等待数据服务器的连接请求，数据服务器在需要与转换器通讯的时候，向转换器的监听端口请求建立TCP 连接，连接建立后，数据服务器可以随时向转换器发送数据，转换器也可以随时将数据发送到数据服务器，在完成的通讯后，数据服务器可以主动要求断开连接，否则连接一直保持。
PCD2.M48X characteristic:
→ it has five operation modes: TCP server, TCP client, UDP, virtual serial port and point-to-point connection;
→ based on network software, users can communicate with C2000 E210 without any modification;
→ by installing our free virtual serial port software, users can communicate with C2000 E210 without any modification;
→ for users who need to develop software, we provide communication dynamic library, setting dynamic library or ocx control for free;
→ set parameters throu browser, setting software or dynamic library;
→ support DNS domain name resolution function;
→ low consumption design, sink required;
→ watchdog design, stability.
Working mode:
1. As a TCP server, after the converter is powered on, it waits for the connection request of the data server at the specified TCP port. When the data server needs to communicate with the converter, it requests the monitoring port of the converter to establish a TCP connection. After the connection is established, the data server can send data to the converter at any time, and the converter can also send data to the data server at any time. After the specified communication, The data server can actively request to disconnect, otherwise the connection will remain.
