#11 Let's automate using GRAFCET, Gemma with Node-red & Factory IO

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 see how all together is working.

See you!

#12 Send Modbus TCP data with Siemens PLCSim Advanced operation

Imagen
Hi everyone, Siemens PLCSim advanced is a new PLC simulator you can use with Tia Portal and much better than the older PLCSim integrated. It's a different program to be installed but now we can simulate almost a real PLC including several comunication protocols. This is very useful when we are learning or testing our programs and we still don't have a real PLC available or we are designing with our digital twin machine. In this video I want to show you how you can comunicate PLCSim Advaced with Modbus TCP protocol, after this, lots of practicing are available without having any real PLC. Keep in touch

#7 Siemens Tia Portal PLCSim simulating S7-1500 & HMI & Wincc Runtime. Good automation leaning tool.

Hi everyone, Siemens Tia portal is one of the best automation tools which integrate PLC, HMI, and Scada Programming besides drives, servos and much more. You can download Tia portal easyly from Siemens web site, then you just have to create and account and you will get a trial for 21 days. https://support.industry.siemens.com/cs/document/109772803/descarga-del-simatic-step-7-incluyendo-safety-y-wincc-v16-de-prueba-(trial)?dti=0&lc=es-WW I recommend to install SIMATIC STEP 7 Basic/Professional, STEP 7 Safety Basic/Advanced y WinCC Professional (trial) and STEP 7 PLCSIM (trial) to try the simulation although you can install SIMATIC S7-PLCSIM Advanced instead, with much more options and which you can even simulate a more realistic S7-1500 controller. https://support.industry.siemens.com/cs/document/109772889/descarga-del-simatic-s7-plcsim-advanced-v3-0-de-prueba-(trial)?dti=0&lc=es-ES Here you have a video where to see how it works:

#2 OPC-UA server / client with Node-red

Imagen
I've been testing how to implement a OPC-UA server / client with Node-red What's an OPC-UA server?  Usually, it's a server that let you to read tags from different PLC's, it doesn't matter PLC brand, and then, it serves this tags to other systems like other PLC's, Scada, Computer systems (SAP, ERP...), Databases,... In IIOT (Industrial Internet of Things) applications it's a really good idea to use a hardware that let you to implement and OPC-UA server. Actually, you can use propietary systems like WEINTEK, WAGO, Weidmuller,... or simply use a Raspberry Pi to do so, like it's shown in this video: So, I've simulated a Modbus server (it would be our PLC) and, after this, Node-red's read the tags with a Modbus client and it has written the tags to the OPC-UA Server. Later on, I've read these tags with a OPC-UA Softwate (UaExpert) and, with a Node-red OPC-UA Client which has published them in a Node-red Dashboard. ...
