Installation Node Red dashboard

Node red Dashboard
Node red has dashboard to create and view dashboards to interact with the devices in the internet of things.
There was an earlier version call node-red-contrib-ui which was replaced by node-red-dashboard created by Dave Conway-Jones (dceejay) thanks for your great contribution.

In this case we will install this add to our Node-red, previously installed Lubuntu (Ubuntu) in next tutorials integrate devices already used previously as Arduino and ESP8266.

Dashboard installation for developers

Enter a folder / node-red

 cd ~\.node-red\node_modules

Copy from github repositories

git clone https://github.com/node-red/node-red-dashboard.git

Enter folder node-red-dashboard

cd node-red-dashboard

Build application

npm install

Back to Folder node-red

cd ..

Run node red

node red

Dashboard widgets available

Example

Organization and Design Dashboards

The dashboard tab to organize our dashboard by tabs and groups since it does not have a tool own design, but consider this way very practical to design without worrying about compatibility design screens different resolutions on devices like smartphones tablets and pc.

Installation node Modbus TCP Node Red

scada Unknown 4:19:00 p.m.

In the search for attachable communication protocols Node-Red I found thanks to the collaborative development a library or nodes for communication Modbus TCP IP, the following tutorial is indicated as installing the nodes in lubuntu (Ubuntu).

Previous tutorials Recommended
Tutorial 1 : Install Lubuntu (Ubuntu)
Tutorial 2 : Installation node red platform
Tutorial 3 : Installation Node Red Dashboard

This library node-red-contrib-modbustcp was created by Jason D. Harper was based on the jsmodbus library, this library allows our Node-Red server is configured as master Modbus TCP, it contains 2 nodes one reading and one writing .

- your user linux - /node-red/node_modules/

npm install node-red-contrib-modbustcp

Update ESP8266 Industrial Modbus TCP IP V2.0

wifi Unknown 1:14:00 p.m.

There have been numerous applications in the ESP8266, I have taken as a goal to integrate this module into one of the industrial protocols most commonly used Modbus TCP IP, it would be good to have a node or sensor that sends data or a driver, OPC, PAC, PLC, HMI or SCADA.

A long time ago I found a group of people in forums.adafruit already had an advance and example have been implemented and improvements suggested by ibbba for the contribution.
The programming code for ESP8266 in this case was implemented in Arduino IDE versions 1.6.4 above. These 2 tutorials indicate connection and basic programming ESP8266 01 and 03 modules.

TUTORIAL

TUTORIAL

Previous tests library ModbusTCPSlave
ESP8266 - 01 Modbus Slave TCP IP (Ethernet) for Industrial Applications

CONCLUSIONS
In previous tests with the library Original ModbusTCPSlave, it had two drawbacks of application:
Code Execution
properly functioning communication modbus tcp, but do not run the code in the routine void loop, as a temporary solution the library for ESP8266 amending stop the connection and reconnect again, the problem with this method is time reconnection can make the teacher while accepting the data indicate error in data reception.
Serial port
Originally ESP8266 the serial port was used as a debug port in hexadecimal, I have made changes to the library so that Serial can be used freely.

VIDEO Update ESP8266 Industrial Modbus TCP IP V2.0

IMPROVEMENTS

With the new modifications it has been omitted disconnection allowing a constant flow of communication if stop the connection between the ESP8266 and modbus tcp master mandatory.

Ticker

He has implemented Ticker library created and documented by igrr, it is an object to call a given function with a certain period. Each Ticker calls a function. You can have as many as you like tickers, the only memory limitation.

Important note: When creating tickers consider not create any delay would affect both modbus communication protocol, such as the execution of that function.

TESTING

the connection between the ESP8266 and a simulator configured as master Modbus tcp was made.

-initially The Ticker Parada is created.

CODE DESCRIPTION

call the function value is created and defined 2 Holding Registers:

Mb.MBHoldingRegister[0] = Holding Registers 1
Mb.MBHoldingRegister[1] = Holding Registers 2

Mb.MBHoldingRegister[0] send a random(0,51) value to the Modbus Master and validate the upgrade value.

Mb.MBHoldingRegister[1] is used for reading a value sent from the Modbus Master and from the serial terminal validate the update.

modbus routine Mb.Run(); is executed; and execute the Ticker Parada.attach_ms(25,valor); every 25ms doing the value created in the function.

Taking this example as a basis, they could perform management functions for I / O similar and digital, load and others, taking only into account not implement any delay.

Introduction Plataform IoT Thinger.io

wifi Unknown 1:31:00 p.m.

This time I bring this IoT platform called Thinger.io, in this tutorial as NOTED create an account to register our devices either Arduino, Raspberry Pi or other data collection platform in my case tests effected, with the ESP8266 01.

This platform allows monitoring and control of variables without any complications.

Test ESP8266 + DS18B20 Onewire + Google Speadsheets (Google Docs)

wifi Unknown 7:36:00 a.m.

If we want a simple solution to monitor temperature, for complicate applications?

if we have Google Docs, This test perform temperature measurement using a probe DS18B20 and transmit directly to Google spreadsheets using as Google app script bridge.

For this test approximately every 10 seconds temperature data was sent.

Requirements

Arduino IDE

Programming ESP8266

Google Docs account

Connection ESP8266 and Google spreadsheet (Google Docs) Direct

I tested the bookstore Library HTTPSRedirect created by Sujay hadke (electronicsguy) thanks for their contribution to the ESP community, in your example creates a kind of chat between Google Docs and ESP8266, below a tutorial video where settings are explained and Connection.
