PROFIBUS Physical Wiring and DP Connector Diagram From the diagram, it can be seen that when the switch is turned to “ON”, terminals A1 and B1 are connected to the termination resistor, so only A1 and B1 can be connected at the end of the DP network; otherwise, the termination resistor cannot be connected. When … 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
WeChat Search Technical Training The M580 is Schneider’s medium to large PLC, powerful in functionality, while the S7 200 SMART is Siemens’ small PLC, widely used in industrial settings where communication between two PLCs is often required. The M580 supports both MODBUS TCP and Ethernet/IP industrial Ethernet protocols, and the S7 200 SMART can also … 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
