I've got a CR9000X that has noisy T/C probes. Scan times are the default 40us and I want to change this to the 60Hz integration filtering time (16ms). The logger in set up in a wind tunnel with enough electrical wiring around to be a concern.
I have some 100 sensors. I also need to send these out on a CAN bus every 500ms.
The question here is do the analog input boards perform scans in parallel, or are they sequencial? In other words, can I pull ALL the data in 16ms, or will it be 16ms * 100?
I've read through the manuals and did not catch a section that addressed this issue.
Thanks for your help.
I tried putting in scans for 3 cards, and get the following errors which tend to make me think that scanning is sequential and not parallel. Blah.
line 93: DataTable with interval > 1 hour cannot be called by scan whose interval is not an integral second is not divisible into a second.
line 76: Scan interval too short for measurement sequence by 503610 usec.
