Practical Tips and Techniques
Every Opta IoT PLC comes with the ability to be programmed using the professional series Arduino PLC IDE. (Arduino PRO) This is designed to implement industrial machine control functions and programming, including ladder logic. The Opta hardware is also designed to support industrial voltages. This quick start guide will show you how to wire, initialize, … Read more
The Arduino Opta can be programmed with basically two different software packages. The Arduino IDE and the Arduino PLC IDE. Arduino IDE is the traditional programming package for sketches (programs). C++ is used in sketches to develop your logic. Arduino PLC IDE will transform the Arduino Opta into a micro-PLC controller. Programs can be written … Read more
Arduino, the leading open-source electronics platform, has recently launched a new piece of hardware called the Arduino Opta IoT PLC. The device has been designed to enable the development of advanced industrial automation solutions, making it a game-changer in the world of IoT and Industry 4.0. In this blog post, we will look closer at … Read more
We will use an MQTT broker in Node-RED to communicate to the productivity PLC clients. MQTT stands for Message Queuing Telemetry Transport. This simple ‘publish and subscribe’ communication protocol does not take too many resources. Constrained devices with low bandwidth are ideal for MQTT. This protocol provides machine-to-machine (M2M) connectivity, perfect for the Internet of … Read more
A human-machine interface (HMI) is present in some form for every PLC. The HMI connects a user to a machine system to exchange information or control data. This interaction with the system can be through hardware or software. HMIs offer different people information and control in many ways for the automated system. Operators, supervisors, mechanics, … Read more
PLC manufactures have their own proprietary protocols. These methods of communication will allow you to program the controller. Other protocols will allow you to collect and log information from the programmable logic controller. Node-RED has the ability to read and write to the Omron controller using special protocol commands. We will connect Node-RED to the … Read more
