2) Communication Setup
The web server adopted by XGB high-performance PLC module is supposed to send one data packet per one scan
to minimize the impact on scan time. In this structure, if the response to the sent data packet is not immediately
received, the next packet will not be sent until the response is received. However, in the case of Windows, when
receiving data packets, generally, it is supposed to wait until 2 packets are received and send responses without
responding to all packets or send the response in 200ms. Therefore, if you operate the web server in Windows
without changing the registry, the communication speed will decrease. That is why the web server provides the
program to change communication settings to solve such a problem. After downloading the program as shown below,
it is recommended that you set up the program so that ACK is sent every time the Windows’ TCP/IP receives one
packet.
