Practical Tips and Techniques
Photoelectric sensors detect the presence or distance of objects in various industrial applications. They typically integrate all necessary optics and electronics into a single unit, requiring only a power source to function and provide an output based on their specifications and the object detection criteria. Photoelectric sensors, also called photo eyes, detect object presence or … Read more
To ensure the proper functioning of any PLC digital input, it is crucial to correctly test and wire the discrete inputs. By understanding the testing process and providing accurate wiring, we can guarantee the optimal performance of our PLC hardware. Testing the inputs allows us to verify that they function as intended and that our … Read more
What is a proximity switch? A proximity switch is a type of sensor that detects the presence or absence of an object without physical contact. It uses electromagnetic fields, light, or sound to sense the proximity of an object. This technology is widely used in various industries for automation and control purposes. Proximity switches are … Read more
To get started with the XY-MD02 temperature and humidity sensor, we will be using the program PuTTY for serial communication. We will use RS485 serial communication to establish a connection and show how to read the values and parameters of the XY-MD02 sensor effectively. Additionally, we will explore the automatic polling feature, which allows for … Read more
The XY-MD02 temperature and humidity sensor uses Modbus RTU for communication. Modbus RTU (serial) works as a master (client) to slave (server) communication protocol. To add this sensor to an existing network as another unit number, you must set it up first. We will be using the Simply Modbus Master software in demo mode to … Read more
Using Modbus RTU (RS485), we will connect the XY-MD02 Temperature and Humidity Sensor to the Click PLC. The Click will be the Client (Master), and the Sensor will be the Server (Slave). This is an ideal sensor to place in a panel to ensure that the panel is within a working temperature and humidity range. … Read more
