Hello all,
I'm doing an internship to renew the software and computer hardware of a rollerbench with NI and LabVIEW. The rollerbench remains unchanged.
The only experience I have with NI and LabVIEW is the Hands On of last thursday. So I hope you can help me sort some things out.
At this moment these requirements are fulfilled:
- 8x AI (250kS/s)
- 3x AO (100kS/s)
- 48x DIO
- 4x counters
- CAN-bus
The system also runs a PID controller with a max loop time of 0,5 ms.
I have configured some possibilities replacements:
cRIO-9024 (800MHz) + chassis + 9205 (AI) + 9263 (AO) + 9493 (DIO) + 9862 (CAN) = 10k EUR
cRIO-9074 chassis incl. (400MHz) + 9205 (AI) + 9263 (AO) + 9493 (DIO) + 9862 (CAN) = 5kEUR
PXIe-8102 + chassis PXIe-6363 (32AI+48DIO+4AO)+ 8513 (CAN) = 10k EUR
Dell Presision T5500 + PXIe-6323 (32 AI, 48DIO, 4AO) + 8513 (CAN) = 5k EUR
The most interesting system is according me the cRIO-9074, but my contact person at NI says it is possible too slow for my application with the high loop rate of the PID controller as main reason.
Normally, the second place is for the PC + PCI-e cards, but NI don't give any garantee it will work without problems. So the PXIe-configuration takes this place in as the reliability of the roller bench is highly recommended.
What's your opionion about this question and is there maybe a better configuration possible?
Thanks in advance.
