I Personally Like your Videos you are a Best Man your are a best Teacher.
Thank you sir.

[@OnosTech]

Wow, thanks

[@raymondcwkoh7458]

learning from your video. Hello from Singapore. And thank you sir.

[@OnosTech]

@@raymondcwkoh7458 I am glad it is helpful

[@donnyblackston1676]

Very good video, thank you very much.

[@OnosTech]

Glad you liked it!

[@ragulr7168]

Very useful tutorial brother..... Thank you

[@OnosTech]

You're welcome!

[@imtiazahmed-vl9yn]

Wait for a positive response...
Thank you Sir

[@imtiazahmed-vl9yn]

Hello sir, this video is also great

[@tanachaiphoset3451]

Thanks you

[@OnosTech]

You are welcome

[@tsfd6275]

I would love a modbus TCP video like this one please.

[@OnosTech]

I will build on this video for TCP

[@imtiazahmed-vl9yn]

Thank you

In which analog values Read and write

[@imtiazahmed-vl9yn]

Plz make a video for FLPROG tm1637 display module

[@mughalsengineering8821]

Please Communicate to Scada using nodemcu wifi Connection

[@imtiazahmed-vl9yn]

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!!!

[@OnosTech]

Thanks KARTE!
They have the same specification but different brand. ESP-WROOM-32E is Espressif brand and ESP-32S is Ai-Thinker brand.

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

[@OnosTech]

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

[@karte2626]

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!😀!

[@OnosTech]

Did you connect two TTL to RS485 converter module to the two Arduino nanos?

[@OnosTech]

Send your circuit schematic to [e-mail]?

[@imtiazahmed-vl9yn]

And digital values read and write

[@imtiazahmed-vl9yn]

If possible Arduino mega 2560 and HMI OP320 configuration set-up

[@OnosTech]

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

[@imtiazahmed-vl9yn]

@@OnosTech ok I'll be waiting..

[@ragulr7168]

Same steps follow for Arduino uno ?

[@OnosTech]

Yes please

[@mughalsengineering8821]

Sir please Using Nodemcu and link scada.
Please sir make a video.

[@temyraverdana6421]

Hi, very interesting, I would like to try some experiments to read solaredge inverter data via modbus.
Tanks a lot

[@OnosTech]

You are welcome

[@ragulr7168]

Your software version 8.1.0 correct

[@OnosTech]

Yes, but you can also use a recent and stable version of 8.2.1

Can you give me license key please
