Practical Tips and Techniques
This introduction to IoT Industry 4.0 overviews the concepts and practical approach to the Industrial Internet of Things. Industry 4.0 builds on the digital revolution brought by Industry 3.0, which introduced computers like PLCs to the manufacturing floor and took us to the next level of technological advancement. The Internet of Things (IoT) protocol and … Read more
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
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines, like the palletizing conveyor machine, that show different programming techniques. The palletizing conveyor example is one of these machines, and we will use the Click PLC programming software. This will demonstrate a sequencer example. In this case, a box … 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
