Profibus-DP Communication Between S7-200 and S7-300 PROFIBUS Fieldbus 1. Profibus-DP Communication Between S7-200 and S7-300 PLCs 1. Analysis: The S7-200 PLC does not support the DP communication protocol and does not have a Profibus-DP interface, so it cannot be directly connected as a slave. However, it can be connected to the Profibus-DP network by adding … Read more
The S7 protocol is the standard protocol used for communication between SIEMENS S7 series products. Its advantage is that both communication parties can establish a communication connection through the S7 protocol, regardless of whether they are on the same MPI bus, the same PROFIBUS bus, or the same Industrial Ethernet. The data exchange is independent … 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
