Coded with RevPiModIO, starting with RevPiPyPlc

We are developing the RevPiPyPlc system as well as RevPiModIO!

This is primary a tool to start and monitor your python program on the revolution pi during system start up. You can transfer and debug your python program over the network, too.

It consists of two components:

  • RevPiPyLoad – Daemon for the RevolutionPi
  • RevPiPyControl – Graphical Interface for the control, monitoring and transfer of Python Programs
RevPiPyControl

With this program, which was also written in Python, all tasks can be performed over the network with the RevPiPyLoad. The program uses the tkinter for windowing and therefore runs on Linux, Windows and Mac, if Python is installed.

This program allows you to create your own RevPi systems in a list to allow quick Access.

A very cool feature is the “watch” mode!

The current values of the IOs in the process image can be viewed in the user interface. The system also writes outputs to the process image on demand, for the IO check – very useful for the first start with the Revolution Pi without further software installation and programming: D

Besides the possibility to view the log files and to control the Python program, we can also import and export the piCtory configuration.

You can find everything else in our documentation!

RevPiPyLoad

This program is running as a service on the RevPi in the background. It starts the transferred Python program for the control and monitors it. Outputs of the program are being written to a logfile.

It offers various settings in the /etc/revpipyload/revpipyload.conf file.

  • Should the Python program start automatically?
  • Should it be restarted after a crash?
  • Should the entire process image being set to NULL if the process crashes?
  • etc.

In addition, an XML-RPC server can be activated, with which the following possibilities are made available via the local network (NOT INTERNET):

  • Start / Stop the Python program
  • Read logfiles
  • Send or download a Python program
  • piCtory configuration
  • Download process Image as DUMP file
  • Watch online the process image and set outputs
  • etc.

These tasks can be carried out via a graphical user interface from another PC.
