– OPC? other generic protocols?– Requests, vendor contacts, models, timeframe
Most are bi-directional

Start with all points compdev = 0.5%span or 0.25% span
Add exceptions for specific groups of points to refine first guess

Temperatures– Set for engineering units 1degf / 0.5degc– Or appropriate for process (larger dev for
furnaces & high temperature processes)
Power– Set for 0.1% span– Low noise measurements

Yield Measurements
Custom tune yield calculations appropriate to production reporting requirements

compdev / compdevp
PI – SMT tool shows both attributes by default
Compdevp takes precedent over engineering deviations!
When both columns are shown in SMT then only the compdevp contents matters.
![Page 31: Technical Reflections By Don Smith OSI Software, Inc.](https://reader035.fdocuments.us/reader035/viewer/2022081507/5518a0bd550346c31f8b4876/html5/thumbnails/31.jpg)
April 2000 OSI Software, Inc. 37
A blank value of compdevp causes the default compdevp to be applied regardless of compdev value.
Remove the compdevp column to cause the compdev attribute to be applied
![Page 32: Technical Reflections By Don Smith OSI Software, Inc.](https://reader035.fdocuments.us/reader035/viewer/2022081507/5518a0bd550346c31f8b4876/html5/thumbnails/32.jpg)
