Update ESP8266 Industrial Modbus TCP IP V2.0



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.

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


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.




Important note:
To perform this test is required to see the previous tutorial, settings for Google script and Google spreadsheets, Below are the sofware related to this project.

I have made changes to the library so you can control the GPIO 2 of our ESP8266, writing on or off, the ESP is constantly done reading cell A2.
Modifications
Temporary change in library HTTPS Redirect.ccp to turn GPIO2, receiving the socket "On \ r"or "Off \ r".
IMPORTANT NOTE: For this example must download the modified libraries, link down on downloads.

ESP8266 program with Arduino IDE in 5 minutes




This ESP8266 default module that works by AT commands, thanks to the contributions of the community has made integration with Arduino IDE.

This module (ESP8266) integrates the capabilities of an Arduino + Wifi (Ethenet) and easily the perfect combination for more or less one dollar, just personally I use in my applications in industrial integration, this module is perfect.

Installing ESP8266 in Arduino IDE is only valid from version 1.6.4 and above, in my case there are newer versions but I liked the version 1.6.4 and it worked perfect.

Video step by step explanation Installation and configuration Arduino IDE


Materials 
1 ESP8266 - 01
1 Conventer FTDI Usb - ttl serial 
3 Regulator de 5v a 3.3v
2 Pushers
1 resistor10k
1 Diode Led

Connections
SW1 = GPIO 0 (this pin to LOW = Bootloader Mode - Programming Mode)
SW2 = RST Reset (reset pulse module)

ESP8266 PINOUT

INSTALLATION, CONFIGURATION AND PROGRAMMING
With the next step you programmed your ESP8266 with Arduino IDE:

Step 1 . Download copy Boards Github: https://github.com/esp8266/Arduino


Step 2 . Open Preferences Arduino IDE and paste additional board
http://arduino.esp8266.com/stable/package_esp8266com_index.json


Step 3. Open Board Manager


Step 4. Search ESP8266 install library


Step 5. Open Board to select and configure ESP8266 Generic.


Step 6. Prepare Blink code example using the GPIO 2 output.


Step 7. Place GPIO0 (SW1) to position LOW Bootloader mode


Step 8. A pulse SW2 (Reset) and SW1 = LOW


Step 9. Keep GPIO SW1 = LOW

Step 10. Download code (Blink)


- Uploading Code


- The ESP8266 and FTDI module should flash


- Code uploaded to ESP8266


Step 11. Switch SW1 and SW2 Reset with a pulse (RST)


Step 12. RUN mode, the program should run normally

Step 13. Connect diode led to GPIO 2



Ready....

If set again ESP8266 mode AT commands with the same circuit and can configure the following video by Default, upload firmware by default.
