OpenRTDynamics (ORTD) is a novel approach to the implementation of block /
signal based schematics, as commonly used in control engineering and signal
processing. The implementations are real-time capable (like the ones produced by
Real-Time Workshop® or Scicos Code Generation). This framework is suitable for
time discrete signal processing algorithms, using the same principles like in
Scicos or Simulink. However, schematics are described by combining special
Scilab functions provided by the framework, which enables advantageous
features:

Additionally to standard approaches, ORTD features the ability to implement
state machines represented by multiple, switching subsystems (each subsystem
corresponds to one state). Since, subsystems can also run in the context of
separated threads (with or without synchronisation to another one), e.g. high-
and low frequency parts can be divided or computationally intensive tasks can
run in the background. Because of a remote control interface and the ability to
include Scilab-Code as computational functions (S-function like), ORTD is also
ideally suited for laboratory automation. The ability to replace sub-schematics
with new implementations and parameters during runtime removes the effort of
restarting the main real-time program when new algorithms are (automatically)
designed.

This is the Scilab-Interface for OpenRTDynamics (openrtdynamics.sf.net). You can
define signal-based block schematics and get the encoded implementations
(similar to binaries), which can be transfered to target machines. However, for
running those implementations, you need the whole framework (especially the
ORTD-interpreter) on the target machine. Also having the interpreter installed
on the development host is advantageous, because then you can perform off-line
simulations.

Comment from Jeff Waters -- September 5, 2014, 06:03:08 PM    
I am having problems installing OpenRTDynamics.  It was on my Lenovo notebook running an
earlier version of ubuntu... I am now running ubuntu 14.04 and when I updated to 14.04 I
encountered problems with ORTD.  I have now gone thru the manual and Graphic installations
and ORTD does not show up in Scilab 5.4.1 that I allowed ORTD to install.  I also have
Scilab 5.5...

It seems that perhaps ORTD is checking scilab files and finding them and thus not
installing them ??? 

Im not familiar enough scilabs' internals to check them and verify their correctness.  

ANY HELP IS APPRECIATED ??? 

Thanks 

Jeff

Dear Jeff,

you could have a look into the folder scilab-5.4.1/share/scilab/contrib of your Scilab 
installation. There must be a link called "ld_toolbox" to the ORTD-Scilab Toolbox
that is 
normally created by the installation procedure or by the "make
install_toolbox"-command in 
order to show up in the Scilab-Toolboxes menu. For me it looks like:

chr@ch:~/tmp/scilab-5.4.1/share/scilab/contrib$ ls -l
insgesamt 24
lrwxrwxrwx  1 chr chr   56 Sep  6 11:32 ld_toolbox -> 
home/chrsys/tmp/OpenRTDynamics_source/scilab/ld_toolbox
-rw-r--r--  1 chr chr  118 Mr 29  2013 loader.sce
drwxr-xr-x  9 chr chr 4096 Mr 29  2013 toolbox_skeleton
drwxr-xr-x 11 chr chr 4096 Mr 29  2013 xcos_toolbox_skeleton

If it's not there, you can manually create it e.g. like this:

cd ~/tmp/scilab-5.4.1/share/scilab/contrib
ln -s ~/tmp/OpenRTDynamics_source/scilab/ld_toolbox ld_toolbox

On an 12.04-updated-to-14.04 ubuntu I tried to install ORTD using the current *.sh - file 
and it worked. Maybe that may be different when using a fresh install of 14.04 but I did 
not check by now... I'm looking forward to hear your report, so I can address this 
potential error.
