measComp E-TC alarm IOC init error 106

[Rong Huang via Tech-talk <tech-talk at aps.anl.gov>]

Hello,

When using measComp-R4-23 for E-TC, and set first two temperature inputs as alarm using Instacal, IOC started with errors complaining "devAsynUInt32Digital::processCallbackOutput process write error"

I am using asyn-R4-44-2, synApps-R6-2-1, base-7.0.8.

Tested temperature channel 1 and 2 with alarm T1 = 30, clear T2=29, both medm "inputs" color-change (green/red) and DIO0, DIO1 voltage outputs (TTL 5.0V) told me that the temperature alarm for both channels is working. Hope this minor error does not affect any instrument function.

Thank you!

Rong
