Are cRIO 9072 and 9074 interchangeable?

[gmand]

Hello folks,

I just had a cRIO 9074 start acting funny, and I don't want to use it in production environment. I don't have a spare, and the budget for this year will not allow me to buy another one. I do have a cRIO 9072. I was wondering if I can use RAD to deploy the image from the 9074 to the 9072 (I don't need the 2nd LAN port).

NI seems to group NI 9074/9073/9072 together and all documentation I could find seem to apply to all three. Does anyone know if there are differences between the 9072 and 9074 that would preclude direct substitution? E.g. smaller FPGA, etc.

Thank you!

I don't think that it is possible. First of all, they don't use the same FPGA chip.

If you have the source code, migrating to a new target and recompiling the code should be fairly easy. See Moving Examples to a Different FPGA Target

However, since the FPGA in cRIO-9072 has way less resource, there is a possibility that your FPGA code won't fit in it.

The RAD utility (and System Configuration) does not support copying images between different models of cRIO. The 9072 and 9074 have different versions of FPGA, which is probably a deal breaker. You can try moving the image with RAD, but odds are it will fail.

If you need to buy a replacement, give Apex Waves a call.

Thank you very much to all who replied! I was afraid that something like this (a smaller FPGA) could be a problem. I do have the source code, so probably that is the way to go. Many thanks again!
