  There is no how-to. You would have to do it on your own. But most of them are in /var/opt/rcware /tftpboot/ and you will also need /www/ and of course the init scripts /etc/init.d/ - scripts and nginx and maybe some libraries… By the way what is the purpose of this? We worked hard on making the system as much read-only as possible in order to keep your sd card safe... It might be easier to install your packages on the distribution that we created.

  Have you tried the official HMI for crating web GUI? There is a http API but without any documentation. You would have to find out how the communication works from the HMI…

  Thank You for the response, I was charting out how I was going to setup the controls for the system and while lining it up the weather came to mind and had to ask. Currently I am just getting the system up and going so automatic control will come at a later date, at that point I will dig into it.

  The time of how often your program is evaluated depends on the complexity of your program and of course on the performance of the HW. I have tested that a simple program like your on RPi 2 B is evaluated every 30ms. You can do a small speedup by changing the sleep time between every loop - in order to do that you need to switch to your main Profile and then on the PLC change the sleep time parameter (default is 50%).

  The web interface can be drawn in the Mervis HMI. However you need your own pictures… There is a detailed tutorial at https://downloads.unipi.technology

  Anything you do in Mervis runs in loop. Make sure to check the basic program example in the documentation https://files.unipi.technology/index.ph ... umentation

  I do not understand your question… In order to make the AO work, you need to provide max 12VDC to the AOV. See this http://unipi.technology/wiki/Using_Analog_Output

  There is no support for audio output yet for any software I came across that works with UniPi so it it up to users how they deal with it…
