Siemens Communication 1. Generally speaking, the communication network of an enterprise can be divided into three levels: enterprise level, workshop level, and site level. Enterprise Level: Top-level management of the enterprise; IT technology applications are very extensive, such as the INTERNET. Workshop Level: Solving communication between different process segments that need to coordinate work within … 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
Multiple How to Exchange Signals Between Multiple PLCs? Previously, I discussed that in some large smart factories, a single or multiple large PLCs usually form the processing core.The advantage of a single PLC is that all important equipment needs to be controlled by this unified core, allowing for high integration of information. However, large PLCs … Read more
Introduction In practical work sites, PLCs are often used to control inverters. There are several ways to control inverters via PLCs, such as terminal control, analog control, and communication control. Among these, communication control has certain advantages over the first two methods, such as being able to read multiple data from the inverter with just … Read more
