Happy OLD millenium!
My Master's project is a controllers testing enviroment on RTLinux
(I will keep you informed).
The program (enviroment) would launch modules as RT tasks. These
modules are code that model the processes to be controlled and their
controllers, both with their inputs and outputs.
Modules must be precompiled. They should have standard inputs and
outputs, and their programmers (automation engineers) should know about
RTLinux features as little as possible. They currently program them in
Pascal for other system, and it would be good if they could keep using
the same language.
I thought about automatically launch other RT tasks, which would
provide module's inputs and catch module's outputs. These tasks would
send the values to Linux tasks through RTLinux FIFOS, take values from
hardware, and do as much as possible to make modules programmation easy.
What I need are ideas about how to communicate the modules with the
input/output tasks. Remember, the goal is that modules get inputs and
put outputs in a unique way, knowing nothing about the input/output
tasks.
Thank you!.
