Subject: ai, soft channel, and breakpoint table
From: John Dobbins <[email protected]>

Is it possible to use a breakpoint table in an ai record to convert the output of another ai record (without loss of resolution)?

I have an ai record for which device support retrieves a floating point value from hardware and puts it directly into the VAL field.

I would like to use a breakpoint table in a second ai record to convert the reading of the first record - which (as I understand it) would require me to use a "Raw Soft Channel". Will a "Raw Soft Channel" ai record, in reading a value into RVAL, convert it to an integer (with a loss of resolution)?

Alternatives?

Thanks and regards,
