Ping Issue Analysis What is Ping Ping is a commonly used network management command and is also part of a communication protocol that belongs to the TCP/IP suite, suitable for Windows, Linux, and Unix. It checks whether the network is smooth or the network connection speed (time) is normal based on the reply feedback results. … Read more
Search on WeChat Technical Training There have been persistent issues with Profibus communication at a certain brewery. Previously, SIAS and on-site engineers had re-planned the entire Profibus network topology, but there were still instances of DP slave devices dropping out, occurring multiple times in a short period, severely affecting the factory’s normal production. Therefore, the … Read more
