Nice tutorial again. It's very useful. I have two questions: 1. Why does the running program sometimes show "0"? because the network is not good when using TPC /IP? Is such a problem possible when using RS485? 2.What should I do when I need to connect and read multiple powermeter/Analyze devices at the same time? Can you offer some advice? Thanks!
@@LearnToLead138 Thank you. Now I am mainly worried that I need to read a lot of data from different devices, maybe 2-10, so polling once will have a high delay, resulting in poor real-time performance
@@LearnToLead138 Thanks a lot for your response! That makes sense. Please don't stop making these more awesome videos. I would like to suggest videos if that's okay.
@@LearnToLead138 Can you please make a video of measuring temperature with thermocouple. If you can use Arduino as a microcontroller and use LabVIEW code to measure the temperature and display it on the front panel.
Hello, good work. What library do you use in this video? Could you send me a link?
It's modbus library
@@LearnToLead138 could you help me in Modbus TCP with IO Link Master and Pressure sensor?
It is obligatory to set unit id?
@goreskyy we can work together
@goreskyy yes
Great work thanks a lot of God bless you

My laptop is wireless connection with device so network disturbance
@@LearnToLead138 Thank you so much 😀.about reading multiple powermeter/Analyze devices, could you give me some experience or advice?
@@form_A_to_Z same method just you have to assign different devices ID number to each meter.

@@form_A_to_Z you can connect 32 device at a time
I wish you could explain why you chose to feed 8 to modbus read for number of inputs and why you chose to join numbers from the output of index array.
8 is to read 8 word of register
And as mannul say energy kWh value save in 2 word so to monitor you have to join 2 word
