Hi Wat_PEA Thailand,

Regarding faster communication, you should consider the following points:

1. Cycle Time: The cycle time of the LOGO! program is crucial. The cycle time is the program processing time, which includes reading inputs, executing the program, and writing outputs. The cycle time of each function is less than 0.1 ms (LOGO!Soft Comfort Online Help: How to establish the cycle time).

2. TCP Connection and Flow Control: The TCP protocol has a flow control mechanism that can affect the response times. If the sender sends data faster than the recipient can process it, the TCP window size will decrease, potentially leading to longer response times (Why under certain circumstances are there very long response times with TCP connections?).

3. Ethernet Connection Configuration: Properly configuring the Ethernet connection in LOGO!Soft Comfort is essential. You can create an Ethernet connection by using network blocks and ensure that the connection settings are optimized for fast data transfer (LOGO!Soft Comfort Online Help: Create Ethernet connection by network block).

By optimizing the cycle time and ensuring efficient TCP connection management, you can achieve faster data transfer rates through the Internet port.

I hope it can help you improve communication speed.

Best regards!
