A) This product has the following three working modes:
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 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 is completed, the data server can actively request disconnection, otherwise the connection will be maintained.
2. As a TCP client, when the converter is powered on, it will actively request the connection from the server until the TCP connection is established, and once it is established, it will keep the 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.
3. There are two 3s. UDP method:
When working in UDP normal mode, KTR2000 will respond to the data sent by all IP addresses and ports, and send the returned data to the IP address and port to which the query request was sent last time.
When working in UDP designated mode, it can receive data from all IP addresses and ports, but only send the returned data to the designated IP addresses and ports.
B) The application software can communicate with the frequency converter in three ways:
1. Redirect the network data to the virtual serial port through the virtual serial port management program developed by our company, and then read the data from the virtual serial port;
2. Use the control edsocserver.ocx (or dynamic library edsocserver.ocx) developed by our company.
3. Use sockets for communication.
How to choose:
High efficiency and low delay. In some traditional serial port transmission applications, 1 15.2Kbps is enough. But if you want to switch to a 100-megabit interface converter, the speed of the embedded device module is higher than 230.4kbps, which will be safer.
Secondly, in some conservative serial port transmission, 1 15.2Kbps is enough, but if you want to switch to 100 Mbps Ethernet communication, the serial port rate will be more guaranteed. Core Huitong JetPort broke the industry serial port rate specification, with a serial port rate of 230.4kbps and a throughput of 45,600 byte/s/s, which is lower than10 ms.
Thirdly, whether the products are serialized or not, we know that the current series of TCP/IP converters (RS232 converters and interface converters) include 1, 2, 4, 8, 16 and 32 serial port to TCP/IP converters. However, many manufacturers only have single-port serial port servers or are not a series of multi-port products with their single ports, and their software and operation are different. From this, we can also judge the professionalism and stability of their products.
High quality serial port server
It will greatly improve work efficiency, improve the utilization rate of existing equipment, save investment, and simplify wiring complexity on the basis of existing network, so it is also a very important task to choose a high-quality serial server. Shenzhen Yu Tai Technology will provide you with more choices.
