Delta plc to Arduino OLED Display - 3 device RS232 communication 

I work with delta plc every day But I can't try communicate all of these devices plc+arduino+oled display it is very helpful. Do it for these people who can't buy hmi and work with small industry Thanx for making video on it

This is a very good video I think the first video with Delta PLC +Arduino+ Oled . If you can share the ckt diagram it would have been gr8.

Thanks Sir you did a great video, you help me a lot. Do more video. Thanks.

Thanks a lot from Kyrgyzstan

Really Nice Video. It helped me a lot to complete my project. Thank you so much.

Thanks sir.for this video

Great video.it is very helpful for us. Thanks .

Very good idea 👍

It would be a lot helpful if u could explain the circuit with a schematic diagram otherwise good video thank u !

Why can't we use the Rx TX pin on the Arduino board to receive serial data? Is it really required to convert serial to TTL and use Didgital input?

Hello, I need one suggestion since you have already worked with RS232. I have a project where I need to communicate (both Rx/Tx) with 16 devices ( industrial Chillers). I know that RS232 is PtP type. But is it possible to communicate with all 16 with my single port (RS232) on PLC? My PLC (Siemens) has to communicate to 16 such devices, how should the physical wiring be done. Is it even possible? I have experience with Modbus RTU (RS485) but I know very little about RS232.

Good morning.. Can i connect delta as228t plc to arduino uno, so that plc can read load cell data that is read by arduino uno and displayed in serial monitor of IDE

Sir, i need a suggestion from you can you help me how to communicate multiple Arduino with delta hmi with rs232 -ttl converter

Can you make the same example, but with esp32?

thank you very much you best, I have weight indicator si4010 with rs232 i want read current weight in delta ss2 plc , i make program for RS in wplsoft the indicator received signal and sent signal but no any data in data registers in plc

Hi, How we can write the data in this PLC delta ss2? How we can generate the communication interrupt with same port COM1(rs232) modbus rtu mode?

Good morning.. Can I connect delta plc master to two slave Arduino or more by rs485 ...... I need to know the program of Delta PLC master... Thanks

I have updated the link to the code in the description. Comment If you want me to do more such videos. I would be happy to oblige

sir ,can u explain me more on PLC ladder logic for sending data from particular register via RS232.

sir can you able to help me in similar project please, i have to get arduino analog value A0 in delta plc dvp14ss2

dear hobbiesntech do you try 14ss2 receive rs232 data from external device. if yes pls send me prog thanks

thanks for the information can you please upload a circuit diagram in your repository and share with details too?

Hi. I would like to send the command "AT + CMGF = 1" via serial communication, is it possible? tanks

sir this same method is also used for delta hmi ??

Is any convertion interface for rs485 to TTL

Sir, can we connect RFID reader directly to Delta PLC using RS232 to TTL converter

Can you provide tha code of arduino and the ladder logic.

Hello HobbiesNTech,
