Thanks Hoang ,I have Loat of learn from your video. Any questions in my automation journey you have solve, i am truly grateful to you
@user-dy9eb7tj7y: So nice of you! A "super thanks" is always a great way for everyone to show the support to my channel and the appreciation of the experience I have been sharing. Thank you for your support to my channel.
That awesomely explained!
thanks, great content keep it up! cheers.
Very cool ! Appreciate your hard working to share those great contents !
@Dennis Jiu: Glad you enjoy it!
I was writing Addr "40004" instead of "4" for 2 hours, many thanks!
@Micha Hydra: Great to hear. Thanks for subscribing to my channel.
Thank you!

excelent!! congrulations master
@alansosadiaz3581: If the information I provided is helpful, would you mind hitting a "thanks" button at the lower right corner of the video to give me a super thanks to show your support to my channel. Once again thank you for subscribing and your big support to my channel.
Engineer I have a question I have a delta HMI and I want it to communicate with a
communicate with a micro 850 by means of the modbus protocol (with a RJ-45 connector)
a RJ-45 connector) this to be able to send data, my question is if a specific
is if it is required a specific instruction in the plc
or only with mapping in the modbus list.
thank you very much for your answer.@@SYPHOANG
@alansosadiaz3581: Modbus is Modbus. It should be very simple but I don't think this video is what you need. Below is the right one you might want to watch. Your Micro850 PLC should be the server. Your delta HMI should be the client. In the server PLC, you only need to set up the "Modbus Mapping" table starts at 1:00. However, in the delta HMI which is the client, you will need set the PLC IP address, slave ID, etc to the server configuration so that your HMI can read and write data from and to the right PLC server. Once again If the information I provided is helpful, would you mind hitting a "thanks" button at the lower right corner of the video to give me a super thanks to show your support to my channel.

"I have a Schneider EM6436H energy meter. I have communicated with it using Micro820. I have used Modbus communication as you mentioned in your video. But the problem is that it sends data in words, but I need to read float data of 8 length. How can I read that?"
Thaks you!
@daljeetsingh3161: I faced this problem long ago. What you need is the sample code available on Rockwell Knowledgebase website. It combines 2 16-bit words back into a 32-bit real/float tag for you. Please let me know if you have any more questions. Thank you for your support to my channel.
hola una pregunta si quisiera cocatenar un dato que viene en 4 registros, como podria hacerlo
@user-fb9rd2dl4l: I don't quite understand your question. Maybe the google translate doesn't do a good job. Would you please leave your comments or questions in English? Thank you.
I facing a problem in micro850 modbus client (msg_modbus2). It gives an errorID of 222
@Mechtronics Services: errorID 222 is for "Network connection fail to establish before timeout." My recommendations is to try connecting client directly to server device. You can also use "Modscan32" to test if Modbus Server device really works FIRST.
Hello Sy, would you share what is your work and what is the hard part of the job.
@nayrbsworld3048: Thank you for your support to my channel. If you really like what I am doing in my channel, "super thanks" at the lower right corner is a great way to show your appreciation to what I've been sharing on my channel. I have been working as an automation engineer since 2018. As I mentioned earlier, the most challenging part sometimes is the network communication. Developing/writing the logic for PLC's can be challenging too but the it should be okay if you are a thoroughly thinking and well organized person.
Can I get a copy of the document you used and are referencing please?
@christopher Guerrero: I already added the link in the video description. Thank you for subscribing to my channel. Should you have any more questions just let me know.

i got error id 130 illegal data adress and i did the same setup like you...
@ambroise musnier: Unfortunately, I am not sure what "130 illegal data address" is. If you figured it out, please share your experience here to everyone... Thank you for your comment.
Hola, me podrías ayudar, necesito enviar datos Modbus del plc por ethernet y visualizarlo en otra pc que se encuentra en otra red.- gracias por tus videos
@diego cajal: I am not sure what you are trying to do but for a Modbus TCP client/master device (your PC) to be able to communicate with any Modbus TCP server/slave devices (your PLC), both devices must be on the same network. That is the first requirement. Thank you for your support to my channel.
This test can be work whit modbus doctor like a server ?
@vladimirgp139: Unfortunately, I am not familiar with Modbus Doctor.
I can't find ANYTHING about what to do with LocalAddr, you showed it in the video but didn't do anything with it.
@Jim H: “LocalAddr” is an array of multiple data elements where collected data from servers is stored. It’s just like a shopping cart for the PLC to store data it just collect from the servers. To process collected data is another topic. That’s why it’s left alone in this video.
what is target device modbus data address ,,sir
@babu: It is for the device your PLC want to send data to OR get data from.
