Python Mobile SCADA
This is a small SCADA package that will run on Linux (preferably) or Windows. The server runs as several modules on the host, sharing information through a message bus. A subset of modules is:
- Bus server - shares tag values with by exception updates
- Modbus client - reads and writes to a PLC using Modbus/TCP
- History - saves data changes, serves history to web pages
- Web server - serves web pages which connect with a web socket
- Web pages - an Angular single page web application
Web pages are responsive and defined procedurally from the
wwwserver.yaml
config file.
Trends use uPlot.
Objectives
Traditional SCADA has a fixed 19:6, 1920x1080 or some equivalent layout. It's great on a big screen but not good on a phone. Hence Mobile SCADA with a responsive layout.
I wrote Mobile SCADA to provide a GUI to the other things I was trying to do, I wanted to leverage web browsers and eliminate a dedicated viewer.exe. Display on the client is fast, trends, as fast as I can make them.
Uptimes should be excellent. The best I have on an earlier version is over 5 years for about half of the script modules. This version is a complete rewrite, however the aim is the same.
All tag value updates are by exception. So an update from you setting a value to seeing the feedback should be FAST.
