People,
I have been touring the Puffin Project site and have signed on as a member (?) out of ambitious interest. Although I am not a hardcore C/C++ programmer, I do work with the IEC-61131-3 languages as a consultant.
I would also like to respectfully submit an idea to the project on other I/O methods. Although the Modbus is a longstanding protocol, there are also others available which offer more reach and capacity for the true PLC programmer. Specifically, I feel that we should actively include other open bus protocols under the umbrella of IEC-61158.
Within the definition of IEC-61158, these are truly open fieldbuses which allow one to design a control system of much greater capacity and speed than the Modbus protocol. Included in this definition are Profibus and InterBus. Both are German-made fieldbuses with a strong following in the automation sector.
With a little investigation, I have been able to locate a project out of Luxembourg that developed a Solar Energy plant completely on
the Linux platform while utilizing InterBus as the fieldbus (URL:
<http://www.santel.lu/projects/wallace/interbus.html>). These guys have even included their own tarball of the InterBus fieldbus driver for Linux
(<http://www.santel.lu/projects/wallace/interbus.html>). It blew me away the first time I found this. If you want your own copy of the I/O driver, it's there.
Furthermore, I have found that the company National Instruments has developed their own Linux platform software (LabVIEW) for controls and data acquisition (LabVIEW Full Development System for Linux) for about $2,000. So, as I see, there IS a future for Linux in controls.
