》》PROFIBUS DP to Modbus/TCP Gateway Operation Guide Abstract： This article takes the NT100-RE-DP gateway as an example to implement communication between Modbus/TCP Client and PROFIBUS DP devices, thereby integrating PROFIBUS DP slave devices into the Modbus/TCP network. The following will gradually demonstrate the configuration steps of this gateway, which are similar for other models in … Read more
Search on WeChat Technical Training In most cases, the touch screen is connected to the PLC, which then connects to the inverter. However, the touch screen can also connect directly to the inverter without going through the PLC. It can control the inverter’s start, stop, frequency change, etc. Today, we will take the Weicon touch … Read more
1. Product Introduction In some factories, certain situations, and applications, due to some objective factors, wiring is inconvenient. Therefore, Beichen’s S series wireless modules are very suitable. By placing the S series wireless modules in a stable industrial wireless (AP) network environment, PLC data acquisition and device networking can be achieved. The S series is … Read more
