When I added {{sys_variable}} in text box of CUSTOM HTML PANEL, it returns syntax {{sys_variable}} as it is, instead of value of sys_variable.
Please guide

I am able to log out from PyScada successfully, and am presented with the login screen, where I would expect to be able to re-login after entering username and password.
This is not the case. It simply presents the same login screen again.

I have tried this in Opera ver 57.x as well as Firefox 60.6.1esr, with both doing the same thing, and I am fairly sure this is not a browser related issue.

The only way to re-login is to click on the PyScada menu item at the top left corner.
But this opens another tab.

from pyscada/PyScada-Modbus#2 :

I am trying to install Pyscada on Windows. Is it possible to do this?

Hi @trombastic ,

Hopefully this only affects the links at the top of the Read the Docs PyScada page. However, I suspect it might be more than this, as the GitHub docs appear to be out of sync with the Read the Docs page.

Going to https://pyscada.readthedocs.io/en/dev-0.7.x/ and clicking on the "Edit on GitHub" link tries to load https://github.com/trombastic/PyScada/blob/dev-0.7.x/docs/index.rst which does not exist. It should be https://github.com/trombastic/PyScada/blob/dev/0.7.x/docs/index.rst .
Similarly going to https://pyscada.readthedocs.io/en/latest/ and clicking on the "Edit on GitHub" link tries to load https://github.com/trombastic/PyScada/blob/master/docs/index.rst . I'm not sure what this is supposed to load because the project does not contain a single master or equivalent branch.

Thank you for your help. 😊

Hello!
How can I build charts with this library? There is nothing about how to do that http://pyscada.readthedocs.io/en/dev-0.7.x/backend.html#add-a-new-chart
Is it possible or maybe is planned?

Hi!

Disclaimer: I am novice to SCADA systems.

I would like to use PyScada to talk to energy meters using TCP. They communicate via IEC62056 and dlms protocols - I have heard that I should be able to use MODBUS to talk to them.

Can you point me in right direction how I can do that?

The idea is to create a new recorded data table that is more simple to store numbers and boolean (one field) and allows to store strings.

I made some test about the difference using one field for boolean, integer and floats or separated fields as currently, and a field for strings.

Here is the django app used to test :
dbTest.zip

in dbTest/models.py you have :

• RecordedData is the same as currently used in PyScada
• RecordedData2 that store everything in a FloatField
• RecordedData3 is as RecordedData2 with a CharField column
• RecordedData4 is the same as RecordedData3
• RecordedData5 is the same as RecordedData4 but the CharField is a TextField

in dbTest/a.py you have the result :

• RecordedData2 is quite the same as RecordedData : slightly faster and smaller
• RecordedData3 is quite the same as RecordedData2 : slightly slower and larger
• RecordedData4 store a text and is larger than RecordedData3
• RecordedData5 is quite the same as RecordedData4

My proposition is to use the RecordedData4 or RecordedData5 as the new table.

@trombastic, what do you think ?

Hi @trombastic ,

Thank you for your work on this excellent project. I am looking to use PyScada as part of a range of educational equipment which my company is developing (https://www.tecquipment.com/).

I have followed the Installation Guide (https://pyscada.readthedocs.io/en/dev-0.7.x/installation.html). Unfortunately when I get to the the last step (sudo systemctl start pyscada) I get the following error (output from "journalctl -xe").

-- Unit pyscada.service has begun starting up.

I have also tried to follow this tutorial and @cwraig's tutorial on a Raspberry Pi 3 B+ on "Raspbian Stretch with desktop" (Release: 2019-04-08) and come to the same error.

I am new to django. Is there something obvious I've missed? What can I do to further diagnose the issue?

Thank you.
Tim

i have setup the PyScada on Raspberry pi. and i want to communicate it with modbus over tcp. I can loginmto PyScada admin page, but dont know how to send and receive data over modbus

I couldn't seem to complete the installation process, could someone help me? I haven't got a clue what's wrong. I could still get the django server up and running, but the issue is I only get text on the screen (see picture below). Any help will be greatly appreciated, I need to set this up for my course in University. Many thanks!

Currently using python 3.7.5

In PySCADA core events we have the ability to act on a specific event by logging the event and or sending an email. That is great, but, there is an option to select the action where there are four available selections. The option 'record and send main only when event occurs' and 'record and send mail', what is the difference between these options ?

Also, how is it possible to specify the particular email to be sent out ?
In the Mails section, I can add different mails, each with their own subject and text body, but again, how is it possible to make these meaningful by placing variables in the main body ?

For example, If I have two mails, one for a low alarm and one for a high alarm condition, yes, I can say this in the subject, but how can I place actual variable data in the mail body ?

Then, how is it possible to then have the event select the appropriate mail based on the event that occurred ? For example, how can PySCADA send out the mail for low alarm when the event for low alarm condition is triggered, there is nowhere to specify this ?

I have configured setting.py for correct mail settings and this functions fine with a test email.

Hi !
I'm new with Github and using PyScada. (with pyvisa(-py) and pyusb)
I don't know if it's the place to show what I found and how I resolved it.

I'm using 0.7.0rc1.
I change in visa/model.py :
if type(instance) is VISADevice: post_save.send_robust(sender=Device, instance=instance.modbus_device)
elif type(instance) is VISAVariable: post_save.send_robust(sender=Variable, instance=instance.modbus_variable)

to :
if type(instance) is VISADevice: post_save.send_robust(sender=Device, instance=instance.visa_device)
elif type(instance) is VISAVariable: post_save.send_robust(sender=Variable, instance=instance.visa_variable)

I restarted gunicorn and pyscada and I could create a visa device.

Thanks for the great job.

Hello everybody,
hello @trombastic,

is there a possibility to write into a Single Coil?
I want to use Pyscada to turn on a digitaloutput of a Wago module.

If this isnt currently implemented, could you tell me where I can create my own Modbus Functions?

regards
Jan

@trombastic Hi, PyScada is of great use for us. But can I use pyscada to setup a modbus tcp server ( the modbus device act as modbus client, while pyscada act as server) ?
Look forward to receiving your reply.

I am using ubuntu 22.4 and python 3.10. I am installing using quick installation. After installation program works and i can access it and add devices etc. However I have some problems.
1 - No log file is created at /var/www/pyscada/pyscadaserver/pyscada_debug.log. This file doesn't exist

2 - When i run migrations it gives error that there is no file pyscada.core.urls. When i manually copy the pyscada folder which is inside the github repo into the project folder where manage.py is located, that error is gone but i am not sure if it is the correct solution

let me know is any solution is there

Having no value in the COV field for variables and saving the form causes a server error (500).
It should return with form error that field needs a value.

Hi there,

I wanted to ask about some problems I have while I'm trying to use PyScada as an HMI for a modbus device. Let me explain the scenario to let you know what I'm trying to do. I have one Conpot honeypot (https://github.com/mushorg/conpot) running to simulate a PLC device that uses Modbus protocol. It's working fine as I can connect to it with some clients (for example mbtget) and also reading values (coils, discrete, holding... all of them). So I wanted to set an HMI just to get like a GUI where I can show some charts, tables and values that I read from that simulated PLC with Conpot. So, I took a look and I think PyScada is perfect for it.

So, I've installed it following your official documentation (the host version and also the docker version, in different machines, just to try if there was any difference). And once I've installed it and launched it, I can perfectly connect to admin GUI where I can set the scenario for the HMI. Just as a try, I've followed these steps (https://cwraig.id.au/2017/09/24/pyscada-on-raspberry-pi-for-temperature-monitoring-with-ds18b20-on-1-wire-part-4-pyscada-hmi-configuration/) where they explain how to set an easy HMI in a simple way, you know, creating charts, panels, items, view... I've also defined a Modbus TCP device and some variables, and that's not the problem as I've set the right IP address, port, registers addresses and type (coils...).

The problem is that, whatever I define, more or less variables, more or less elements, charts... they never give me a variable value, it's like it's never reading. I can see the tables and charts on the view, that's not the problem, but they're empty. And it's not just a problem of not being reading. The thing is that I don't see any kind of interaction in my Conpot log, like, if it never got an IP connection try.

So I'd like to ask if, besides launching the PyScada, defining the Modbus device, defining the view and HMI elements... I'd need to do something else to make it work, as I feel like it never sends a connection try.

Just to help to understand it, I'm leaving some pictures of what I've configured. I just defined 2 variables to read holding registers as an example. About variable addresses, I used one with address 1 and another with 40001 because I'm not sure if it starts in 1 mapping to 40001, or if I have to set the 40001 number.

Thank you so much!!

With https://github.com/fabiocaccamo/django-colorfield ?

@trombastic, what do you think ?

According to a previous question, I addded this custom html. However on the page I am seeing 0.0 when my variable is not 0.0. I tested this with other variables too. Is there another way to add variables to custom html.

Setting up the chart option I can set the variables for the Y axis, but there is no option for setting the X axis to the timestamp of recorded data.
How is this possible when only my variables are available for selection ?

Can you provide a command list for version upgrades within the version 0.7x stream
I am currently on PyScada Version: 0.7.0b18 and would like to move to the latest.

I would be happy to write these up if you could provide a brief command list.

Thanks again for the project.

On the main page where one can select the application views as well as Admin functions, there is a static image loaded under the Admin title that should be removed.
It shows details for Martin.

I went into the directory and renamed this file so it no longer loads, but this is not the best solution, as it still tries to load the image and fails with broken link reference, but does look better.

I don't see any reason for an image to be shown for Admin menu selection.

I've been working on trying to set up pyscada. Every time I try the command "sudo systemctl start pyscada" it never works. I've gone through the documentation looking to find if I can figure out why the command isn't working and I just can't seem to figure out why. I'm using a raspberry pi 3 B+, the os is Raspbian jessie 8. I added a screenshot of what comes up when I run the following commands "sudo systemctl start pyscada", "sudo journalctl -xn", and "sudo systemctl status pyscada.service".

https://github.com/trombastic/PyScada/blob/c6d7f333f056998f3ab02bf06f692059af1856cd/pyscada/models.py#L1221

displayed order in the web selection drop down.
limit_type_choices = (
(0, 'value is less than limit',),
(1, 'value is less than or equal to the limit',),
(2, 'value is greater than the limit'),
(3, 'value is greater than or equal to the limit'),
(4, 'value equals the limit'),
)

The implemented cases seem to be:
0 = less than
1 = less than or equals to
2 = equals to
3 = greater than or equals to
4 = greater than

I already have Python code that allows me to communicate with NX series (and probably others) PLCs over Ethernet/IP (but really FINS/UDP if I understand correctly).

With that code, how much work do you think it would be to add that functionality here? I started looking around your Modbus integration, but I'm not sure how much of it would be required for FINS because the protocol seems to be simpler.

I can provide more detail obviously just not sure what you need. If you can give me a direction to start in, I might be able to take a stab at implementing it myself and making a PR.

Thanks!

PySCADA Deamon is not failing to start after upgradation

I was able to setup PyScada on a small Cubieboard 2 operating Armbian which is Debian for ARM, which I have used now for many years.

Normally this Cubieboard is running my own C code application that is my own form of SCADA, having Modbus TCP/RTU and built in HTTP server. It normally communicates Modbus RTU to my microcontroller, an Arduino DUE via USB serial on port /dev/ttyACM0. The line settings are 115200 baud at 8 data bits no parity and one stop bit. I use libmodbus in my code and it works fine.

Now, coming to PyScada, I have installed it on the same Cubieboard and have configured what I guess is correct, by looking at the method of this person https://cwraig.id.au/2017/09/24/pyscada-on-raspberry-pi-for-temperature-monitoring-with-ds18b20-on-1-wire-part-4-pyscada-hmi-configuration/

I have set up the Modbus device for protocol being Serial RTU, the framer again RTU and unit ID of 1, which I guess is slave ID.

I next added a variable that links back to this device and using FC3 for holding registers, as this is what I do in my own application.

I have tried various addresses for the data variable as I don't know if PyScada for FC3 would use 0 or 1 or 4000 or 40000 as the first address in the holding register map ?
I have tried all of the above and I get no displayed data in a simple label with value or custom HTML.

I ssh to the cubieboard and can see that /dev/ttyACM0 is there and is not being used by my own application while I test with PyScada.

Do you have any method to see what the Modbus (PyModbus) module is doing or some other backend way to see data or errors ?

On my controller, I would normally see an LED flash each time it is being polled by my application, but not so with PyScada, it appears to simply not be polling this device at all.

Martin, have you tested and proved the Modbus RTU as working and can you suggest anything for me to check or try please.
Many thanks, Paul

Kindly Respond for the above Queries , Eagerly waiting for the answers because company project has been halted for the same

Based on:
https://pyscada.readthedocs.io/en/dev-0.7.x/django_settings.html
When running command:
sudo -u pyscada python manage.py pyscada_daemon init

Gives the following:
Warning: please change 'pyscada' to 'pyscada.core' in the INSTALLED_APPS section of the settings.py!

Please update the documentation to reflect the change.
I have tested this on a new installation on rasbian.

Hi all, that's me again with a new topic now :)

Is there a way through to get the variable data from an API rather than a device, if yes what is the practical one to achieve it?

Thank you.

I am unsure if this is the correct place to post this but I have written a series of blog posts for documenting my installation of pyscada on raspberrypi. I would be happy to have this incorporated into the documentation associated with the project. Let me know if you are interested and I could have a look at moving the relevant components over.

Thanks for all the work that has gone into the project, i hope to have a look into the modbus RTU side in the next week or so.

Hi,
could you share how to read analog value using ADS1115. thanks

Hi @trombastic, pretty cool project. I was wondering what is the state of the project, the plans to maintain it and keep improving it.

Cheers

Hello, I Want to use this on Django 4, my question is this project is dead? or it`s live?
I can contribute to this project because I need it
right now if we change the Django requirement in the setup file it is work it or we must change some code in repository?

I can see the variable value on the hmi by using variable_status page. I want to add a restframework to pyscada and I set it up. I want to retrieve the value of a variable in the code. In the database, value is not stored in variable table. I can find the value from pyscada_recordeddata but this way doesn't seem reasonable. I must order it and filter it and select the first record. That table will have maybe millions of records. How else can i access the value of a variable. In my api I want to say for example:

var = variable.objects.get(id=1)
return var.value

this is pseudo code of course but I am not sure how to access the value.

Creating a view with a "-" symbol somewhere in the link title field results in a server error 500 when accessing the root page.

PyScada Version: 0.7.0b18

The value class key should be unique.
Keep only one value for :

• float 32, 48, 64
• int 8, 16, 32, 48, 64
• uint 8, 16, 32, 48 (missing), 64
• boolean

Should we add other value classes ?

@trombastic : what is unixtime[i or f][32 or 64] value class for ?

Hello, I want to create a HMI for Siemens PLC thanks to PyScada with windows. I wonder how the modbus connection is set and how the variables are changed. I change the values on HMI with the command "$(".type-numeric.var-key").html(Value);" but it doesn't send on modbus. Can you help me ?
Thank you !

The install_docker.sh checks for root user. Why is it needed?

Is ssl required to run pyscada? Why?

When I install pycada according to the instructions or via Docker, I get the error django.db.utils.programmingerror: (1146, "table pyscada_db.pyscada_deviceprotocol doesnt exist"). How to get rid of it?
Installing on debian11

I have tried various methods to get variable data to be displayed in a custom HTML panel, mostly without success. What are the exact options for using this component as there is nothing in the documentation and there must have been some changes since 'cwraig's blog on it' ?

For example, if I want to use four variable which are selected from the variable list, what are the options for use in the custom HTML section, as I have tried using the variable names that I have selected, all without success ?

Also, if I need to use javascript library, say for some for of gauge or dial, can I place the included javascript here or does it need to live at some other location that will be loaded up on application load ?

Many questions :)

When at the main site where one can select either the View pages or the Admin section, a new browser tab is created for either selection.

Also, if i click the PyScada menu item at top left corner, it also creates and moves to a new browser tab.

This should not be the case, all operation should remain within the one browser tab unless the user selects otherwise.

Very quickly, one can have a bunch of open tabs created by PyScada, which annoying as one needs to close them and just work with the one or maybe two, say one for PyScada View and one for PyScada Admin.

In the Modbus Device a check box to set the device to active or not is available.
Saving a device with the 'Active' set false does not stop polling of the device as the background task that does the actual polling remains to exist and continues to operate.

The only way to stop PyScada Modbus Device from polling a slave unit is to set the device 'active' to false and save and then in 'Background Process' either delete or disable the task associated to the Modbus Device.

This task should be ended when the user set the Modbus Device 'Active' flag to false, and restarted when set to true.
