The XP kernel is a closed, proprietary product, but does has a certain amount of scalability, so there are many possible ways to load and configure this OS. There is no way that that the list members could possibly know anything about the OS configuration, or the application code or the tool chain used to build the application, or the test drivers, or the hardware platform and communications (I/O); so the scope of question cannot be defined. The question cannot be correctly answered.
The question should be directed at Microsoft, and the hardware vendors, and the application programmers. I can only say that 'it depends'. As the PFD for SIL 2 is 0.001 to 0.01, the off-the-shelf XP/NT kernel should not be used for the direct and sole control of a system where a software failure would result in harm to a human. There are companies that claim to have developed SIL 2 control system where WIn XP was one of the software components. Before the open-source seeking missiles are launched, I will also note that the current Linux kernel, in its 'raw' form, cannot be used for controlling a system where a failure would result in harm to a human. luck, Brian From: [email protected] [mailto:[email protected]]On Behalf Of [email protected] Sent: Wednesday, June 04, 2008 3:21 AM To: [email protected] Subject: 61508 Safety Integrity Level 2 and Windows XP All, A colleague has asked me for any advice in using Windows XP for a SIL2 application (in an advisory capacity).
