Hi all,
The system in question uses as P4 HP, Labview 6.1, with NI's SCXI as I/O. Second, I should explain what RTC (Real Time Control) is required for my application.
Nominal, control action and DAQ every 0.100 seconds.
Maximun 2 seconds of no control (Control application not main thread), every 1 minute.
Thirdly, the risk associated with loss of control is more product damage base than human safety base.
I am familiar with the Windows OS and its Non-deterministic characteristics. However, is there any means that can be used to keep it under control to meet my application?
Furthermore, I do not have a firm opinion on whether to prevent Non-deterministic behaviour (mimmic PLC based systems) or detect it (external watchdog).
This system already exists and converting to a PLC based system is an expensive option.
You thoughts pls.
