Practical Tips and Techniques
We will now look at communication between the Productivity 2000 PLC (Modbus TCP Server) and Node-RED (Modbus TCP Client). Node-RED is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that uses flow programming. Minimal coding is required; you can see the program flow visually. The best thing is that the software is … Read more
This article discusses the Arduino PLC IDE in Instruction List (IL) format, an industrial programming language that is simple and intuitive for those familiar with mnemonic program code. The Opta PLC can be programmed using any of the five official languages specified in the IEC standard and sketches written in C++. This article will focus … 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
In the current era of automation and digitization, Programmable Logic Controllers (PLCs) have emerged as integral components for varied industries, including manufacturing, construction, and more. Mastering the PLC and what you need to know involves different facets of the PLCs. Understanding their basics to troubleshooting common concerns is crucial in optimizing their efficiency and application. … Read more
