Need IoT Solution

Projects General Guidance
1

Hi,

I am trying to develop an end to end IoT solution using Arduino UNO with Ethernet Shield. I will be reading data from a PLC using Modbus RTU and transferring it to the internet using ethernet.

I need some help for developing the cloud/ web page UI and subsequently an Android/ iOS application for the same.

Following are the basic requirements of the project:

100 tags to be read/written
Web page and Mobile app should contain graphs/ datalogs
Dynamic IP present
I have tried exosite and the sample IoT program provided, but I require a free/cheaper solution with multiple users and customizable UI.

Please provide an example webpage and mobile app if possible.

Thanks,

Komal

What do you propose to use the Uno for.
I don't see an obvious role for it in your description

Please provide an example webpage and mobile app if possible.

First, neither of these is an Arduino problem.

Second, even if they were, we would offer to help you to develop the software, not do it for you.

If you want someone else to write Arduino software you should ask in the Gigs and Collaborations section of the Forum.

Cheapskate. You get what you pay for.

@Robin2
I need to develop a code for monitoring data from a PLC.
Secondly, I need some idea on how data is sent from Arduino to a web page, what protocol is used? What coding is needed on the web UI side?

In your Original Post you said

I will be reading data from a PLC using Modbus RTU and transferring it to the internet using ethernet.

If the data is on the internet why not monitor it on a PC rather than an Arduino.

Maybe it would help if you post a diagram of the data flow that you have in mind. Also an example of the type of data would be useful.

Interestingly, when you say "IoT", the ESP8266 comes to mind. It actually has the stacks built in and somewhat more computing power than basic Arduinos!

Hi,
If you want to monitor PLC values, enquire with the PLC distributor about network connections.
Most PLCs now have network I/O for remote access, which sounds like the application you are looking for.
No need for an inbetween box, the PLC unit does it all.

What make and model is the PLC?
