The control system may be combined with a data acquisition system by adding the use of coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions".
In short words, it's a system that will control outputs, receive and collect data about inputs and present all this data to operator. Unfortunately, most of them cost a lot, are difficult in configuration and demands a lot of knowledge from engineer that configures them.
Probably, on the internet you will find many different proposals of SCADAs and its components - better, worse, cheaper or more expensive. My solution is based on two components:. In next lines I will describe how to integrate all these components into one system. First of all - Advanced HMI has this drivers and moreover, there is Pymodbus library that makes work with this protocol very easy. You can find more information about Pymodbus in my previous article. DHT11 sensor measures temperature and humidity.
First and foremost, it's very, very cheap. On the ebay you will find lots of it. But there is one problem. To read data from this sensor you have to count microseconds quite precisely. There are 40 bits and every bit lasts specific period of time - when it's "0" it's ca. It means that counting time can be problematic.
I have found two libraries that allow you to read data from DHT And I recommend the second one - it makes that your code during counting microseconds has high priority and therefore it's quite precise. I used it to prepare raports - it's very simple to download this file and convert it to more user-friendly Excel. For me Gspread at the beginning seemed to be super easy to implement, but since April it changed and now to have access to your files on Google disc you need to use double authorization - previously your mail and password were enough.
The authorization process demands to configure some settings in Google Developers Console, save these settings to json file, upload it to Raspberry Pi and finally share your file with mail that appears in json file More information about Google API and some goods tips how to authorize the access you will find in these websites:.

I'm trying to use the raspberry pi 3 for industrial application and for that I've connected quite a few sensors temperature, humidity, co2 etc. I'm successfully able to get reading from the individual sensors and wrote a structured program with few functions related to each sensors to get reading from all the sensors in 2 sec interval and display the reading in GUI.
I'm finding it very difficult to make GUI with Tkinter programming and make several pop-ups for my purpose.Amazon Web Services (AWS) IoT MQTT Node-RED Raspberry Pi & PLC
I really don't know how to create an efficient HMI on raspberry pi. I didn't find the right solution from the internet. Thanks for your post. VTScada can only be installed on a Windows computer so you won't be able to install it on your Raspberry Pi.
There are a few scenarios you could try to use VTScada for, but it's not built for what you're doing. Installing Windows on your pi is not what it's intended to do but possible. A better option would be to use the pi as a data soruce and query the data from a more powerful Windows workstation. But your issue is likely with your Python code. Python may be slow, but you should easily be able to process a few hundred values every few seconds.
I've done it and it works, but it's slow. You also need to take a lot of precautions regarding security if your Pi connects to the Internet or pretty soon it's going to be a zombie for somebody's DDS network.
The Pi is a fantastic device for learning a lot about technology. I take one to all of my courses now. You can do some basic monitoring of things around the house and control nifty gadgets.
But, it's not a PLC and never will be. If you want to do industrial monitoring and control, then sooner or later you'll need to use the right tools for the job. The x86 version may run VTScada but we have never tested it and, as such, don't support it.
As per my knowledge TScada can only be installed on a Windows computer so you won't be able to install it on your Raspberry Pi. It looks like Microsoft released a proper Windows build for the Pi 3. See the article below for more details:. Note: I have not tried this as the news just came out a few hours ago and I own a Pi 2B which is not supported.

I need to it runs on raspberry and it communicates with other device for RS The guys over at Proview are getting very close to a RaspPi that works, but it looks like a horrible fiddle at the moment. It seems to be stable. Last edited by maba on Sat Apr 19, pm, edited 1 time in total.
I've been hoping to use the Pi in a industrial application. Around 2 weeks ago I saw the main developer of Proview version 5. I only have a Gertboard. I compiled the Proview source haven't tried the standard deb on the Pi and the basics are working. With the tools from Gordon is it possible to use the AVR, 3. For a strange reason I need to upload the sketch every time after a reboot. Please keep in mind.

If you developed an interesting and beautiful project using Rapid SCADA, and you would like to publish information about it in this page, please email us at info rapidscada. The home page of Rapid SCADA is implemented as an interactive map, which allows an operator to monitor the state of the entire system and quickly navigate to detailing of a desired location.
The developed reports display amount of run hours and number of engine starts per period. The software, provided by the controllers manufacturer, displays only current state of gensets and doesn't implement history database.
Environment Protection The environmental protection project implements the control of the technological process of the landfill located in the US. The water from rain is pumped off the bottom of the dump and flows through local sewage treatment facilities to remove petroleum products and other contaminants. The top is drilled into and methane gas is collected and burned off or used to create steam and energy.
Rapid SCADA monitors the status of pumping equipment, calculates the fluid flow rate and the time before the tanks overflow.
The personnel of the facility are promptly receive alarm notifications via email and Telegram. Pressure Monitoring System The system monitors pressure and temperature of oil products on an oil tank farm. More than 50 segments of the pipeline are under control.Poppy flower

While it's technically possible to do this, in most applications sensors are already installed and connected to a PLC that is also controlling the system. In those situations, there's typically no provisions built into the equipment that would allow you to install additional sensors for a second device. And while some might suggest connecting the Microcomputer to the same sensors the PLC is wired to, since most sensors only have a single output this would often require adding additional devices like signal splitters or converters.
In practice, the most convenient way to collect all the data coming from existing sensors that are already wired into a controlling PLC is to collect that data from the PLC itself. There are definitely advantages to setting up communications with a system's PLC, as apposed to reading the system's sensors directly. The most obvious of which is that you also gain the option to write data back to the PLC.
This means the data your analytics provide can actually be sent to the PLC to effect the control of the process. One disadvantage of communicating with the PLC is that you'll typically need to purchase the specific PLC's communications driver software. When we started our journey to connect the plant floor to our ERP systems, our team didn't really have any PLC knowledge as our team was comprised of several mechanical and software engineers.
What we did have was a requirement that we connect our ERP system with the PLC's in our facility, and with that in mind we started searching for solutions. While there are several drivers you can use to connect to an Allen Bradley PLC, after trying many of them we found the node-red-contrib-pccc to be the best because of its simple structure and efficient functionality.
Now find node-red-contrib-pccc in the search results and install it:. This greatly reduces unnecessary server calls for the same value, improving the efficiency of the system.
