cFP, ETS and RTX

[Khalid]

Hi,

I just want to confirm that on cFP 2120s, the ETS RTOS exists, and not the RTX. Am I right? Is it even possible to install the RTX on the cFPs?

Why do I care, you ask? Well, I want to know if I can use the Real-Time Shared Memory VIs on cFPs. They apparently work only on targets with RTX systems.

Admittedly, I don't know much about the differences between the ETS and RTX targets. If only the KB article (# 3DE7BMXT) on ETS vs. RTX was available online. It's not, as of 23rd August 2006 at least:

Thanks for any input.

Hi Khalid,

I hope you're doing well.  It looks like you're hoping to use the Shared Memory VIs on a FieldPoint controller, and you weren't sure if it was supported.  The Shared Memory VIs are meant to be used with our Real-Time Series Plug-In boards, such as the 7030/7041 cards, to share data with the host.  If you are trying to send data back to your PC from a FieldPoint controller, there are a few different ways to do so: Shared Variables, TCP VIs, or DataSocket.  To answer your question, Real-Time FieldPoint controllers do not run RTX, since an RTX machine runs both the RTOS and Windows simultaneously, and FieldPoint controllers don't quite meet the specs for Windows May I ask why you are looking at the Shared Memory VIs in particular?  If it's just for data transfer to the host, one of the other methods I mentioned are the typical ones used with a Real-Time FieldPoint controller.  Let me know if I helped answer your question, or if you do have follow questions about this.  Have a great day Khalid!
