We have published know-how regarding the implementation of TCP in industrial networks in a Q&A format.

図研エルミック

【Q1】 I want to improve the accuracy of time synchronization using EtherCAT; could you provide some key points? 【Q2】 I would like to build a PLC using Raspberry Pi or CODESYS on Windows to test the connectivity of a product under development; are there any points to be aware of? 【Q3】 Is it possible to analyze a proprietary protocol with Wireshark? 【Q4】 Is there a way to check encrypted data with Wireshark? 【Q5】 Please explain why both UDP and TCP are used for real-time processing. 【Q6】 Please explain why video can become distorted even when using TCP, which guarantees retransmission. 【Q7】 TCP communication sockets are remaining open. What points should I check? 【Q8】 Communication with the server is intermittently interrupted. What points should I check? 【Q9】 Do you have any recommended methods to assess the quality of the network? 【Appendix】 Introduction to engineering services and industrial network implementation/testing support services.
