XY-MD02 Temp Humidity Serial UART Communication

XY-MD02 Temp Humidity Serial UART Communication

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

XY-MD02 Sensor Setting – Modbus RTU Network

XY-MD02 Sensor Setting - Modbus RTU Network

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

Integrating XY-MD02 Sensor Modbus RTU Click PLC

Integrating an XY-MD02 Sensor with Modbus RTU into Click PLC

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

Productivity 2000 Series PLC Modbus RTU Serial

Productivity 2000 Series PLC Modbus RTU Serial Communication

The Productivity 2000 series of PLCs has five built-in communication ports for easy connectivity to your PC or various industrial networks. Serial protocols like Modbus RTU can be utilized with the RS232 or RS485 ports on this PLC. Modbus RTU (Serial) is an open (published) protocol that uses the Master / Slave architecture. It’s a … Read more

Click to Click PLC Communication – Remote IO

Click to Click PLC Communication

We will connect two Click PLUS PLCs and communicate in three different ways. Using the send and receive commands, we will set up one PLC to be the master (client) and communicate with the slave (server). WiFi, Ethernet, and Serial communication will share common memory areas between the Click PLCs. The send and receive commands … Read more

BRX Do-More Simple Modbus Serial Communication

BRX Do-More Simple Modbus Serial Communication

The newest Do-More Designer Programming Software (2.9) version includes a Modbus I/O Scanner. This Modbus scanner will simplify Modbus RTU serial communications to any device. Communications are done independent of the PLC scan time and will have little or no ladder logic for the program. We will be communicating to a Solo process temperature controller … Read more
