Industrial data exchange between field devices can be achieved with the Modbus communication protocol. The Modbus coils, discrete inputs, input registers and holding registers were programmed into the ESP32 using FLProg. The Modbus RTU connection was established between the ESP32 and FLProg SCADA on a computer using the TTL-to-RS485 converter and the USB-to-RS485 converter modules. The programming demonstration circuit uses the ESP32 NodeMCU, LEDs, a push-button switch, a potentiometer, an I2C LCD, a TTL-to-RS485 converter, and a USB-to-RS485 converter module.

FLProg is a visual or graphical programming language that uses PLC's Function Block Diagram or Ladder Diagram for programming Arduino Uno, Micro, Nano, Mega Leonardo, ESP8266, EP32, Intel Galileo and lots more.

I Personally Like your Videos you are a Best Man your are a best Teacher.
Thank you sir.
Wow, thanks
Wait for a positive response...
Thank you Sir
I would love a modbus TCP video like this one please.
I will build on this video for TCP
Very good video, thank you very much.
Glad you liked it!
Very useful tutorial brother..... Thank you
You're welcome!
Thank you
Hello sir, this video is also great
Thanks you
You are welcome
Plz make a video for FLPROG tm1637 display module
And display OP320 HMI analog values and digital State like on off switch in FLPROG platform and possible pic controller like 16F876A ? VIA PICKIT3
Hi Onos:
In the link you recommend to buy ESP-32 there are two options:
ESP-WROOM-32E and ESP-32S
Wich one do you recommend the most?
I already ordered both of them but I would like to know wich is the best for future buyings.
Great job by the way!!!
Thanks KARTE!
They have the same specification but different brand. ESP-WROOM-32E is Espressif brand and ESP-32S is Ai-Thinker brand.
And digital values read and write
In which analog values Read and write
Hi, very interesting, I would like to try some experiments to read solaredge inverter data via modbus.
Tanks a lot
You are welcome
i use arduino nano when connecting to scada, chip CH340 will heat up causing loss of connection, ESP32 will there be such situation? 24/7 connection
I am not sure why the CH340 chip of the Arduino Nano is heating up. You may try the ESP32 or an external CH340 chip module like the USB-TTL Serial Adapter connected to the TX and RX pins of the Nano. s.click.aliexpress.com/e/_Atjr47
Sir please Using Nodemcu and link scada.
Please sir make a video.
Please Communicate to Scada using nodemcu wifi Connection
I also tried a two-slave network with two Arduino Nano and FLProg Scada as the master. Did not work.
It just works with one slave Arduino.
WOULD YOU BE SO KIND ENOUGH OF MAKING A SIMILAR VIDEO WITH 3 OR 4 ARDUINO NANO SLAVES AND FLPROG AS A MASTER?
Thank you very much in advance!😀!
Did you connect two TTL to RS485 converter module to the two Arduino nanos?
Send your circuit schematic to onos.technology@gmail.com?
Same steps follow for Arduino uno ?
Yes please
@@OnosTech but.....not working brother
If possible Arduino mega 2560 and HMI OP320 configuration set-up
I already have a scheduled video in a couple of weeks for the OP320 and the ESP8266 for the current series of FLProg ladder logic which can be adapted to the Arduino mega 2560 controller
@@OnosTech ok I'll be waiting..
Using Trend graph 📈📉
And link ms execl
And analog link
Please sir make a video.
And sorry sir my English is not perfect. 🙂🤗
I am not sure about this
Your software version 8.1.0 correct
Yes, but you can also use a recent and stable version of 8.2.1
Hello Sir
Can you give me license key please
