Hi everyone, I guess some of you know Factory IO, a very easy software to learn automation, handy to connect to lots of PLC and simulators to learn how to code automation with them. So this time I've used Node-red in a Raspberry Pi to connect with Factory IO and to code a GRAFCET with Gemma guide automation program to try if we could use just Node-red to solve an automation problem. To control real I/O, I've finally decided to use a ESP8266 wifi arduino connected to the RPi working as a wifi access point and using MQTT protocol, so it's been connected the Rpi wifi AP just with the Arduino, a PC and a phone to control the Node-red dashboard.  Besides this, I've had to install also a Mosquitto broker in the RPi to do the MQTT communication with Arduino. You'll see how we can test our Node-red code with Factory IO but, after this, we can stop Factory IO and just let the Arduino I/O to change our automation  states and control a real machine. Here you have the video to ...

Hello everyone. Siemens NX is a great tool to create your 3D designs and assamblies and help you as a mechatronic designer to create new machines but , in fact, it can go beyond that. He has a very useful utility called Mechatronic Concept Design (MCD) where you can give phisics to every piece in your design and later connect these pieces to Siemens Tia Portal (using PLC-Sim Advanced) or even any PLC (using OPC UA) to test your PLC programming on your Mechatronic design converted in a digital twin So you can avoid future programming or concept mistakes in the real machine. Keep an eye on this because is going to be very used in the automation early future. Regards.
