For module AO420ELF the knobs AO:SLOW_SET:CH:* use integer as return value

[zack-vii]

AO:SLOW_SET:CH:1 1.5 correctly sets A0_01 to 0x2666 9830. however it internally if set to use integer. So it would return 2 as get value. Should its datatype not rather be float ?

Hello Timo cd /usr/local/epics; grep SLOW_SET db/* db/ao420fmc.db:record(ao, "${UUT}:${SITE}:AO:SLOW_SET:CH:${cid}") { https://github.com/D-TACQ/acq400ioc/blob/epics7/db/ao420fmc.db#L2 This is an EPICS ao record. To the outside world it's a float, but internally in the register domain it's an integer. https://epics.anl.gov/base/R7-0/4-docs/aoRecord.html section Units Conversion Does that answer your question, or is there actually a fault somewhere?. Thanks Peter

hmm well the thing is i use the knobs to control the modules. I used AO_01 (with raw values) and it seemed to work at first but then the user reported that there is actually nothing on the output. The thing is, it it the 5th module of an acq2106 carrier with 4 acq425 modules... I was trying to use other mehtods to set the voltage to see which one would be preferable.. and stumbled over this.
