Re: Block CAPUT to not be able to modify PV value

[Adrian Martinez via Tech-talk <tech-talk at aps.anl.gov>]

Hello Andrew, 

I knew the DISP field but I need to disable UCrTcrLimitUsSet and UCrTcrLimitUsRd when StartUpOn =! 1, not all the time.

Is it possible with DISP?

Thanks, Adrián.

Hi Adrian,

Take a look at the DISP field (described here), when non-zero it disables puts to any field of the record except for the DISP field itself.

Hello, 

I need to block the setting function for some PVs. I was using SDIS and DISV fields:

record(ao, "$(user):UCrTcrLimitUsSet")
{
field(DTYP, "asynInt32")
field(OUT,  "@asyn($(PORT),$(ADDR),$(TIMEOUT))ucr_tcr_us")
field(VAL,  "0")
field(EGU,  "us")
field(HOPR, "10000")
field(LOPR, "0")
field(DRVH, "10000")
field(DRVL, "0")
field(SDIS, "$(user):StartUpOn.VAL CP MS")
field(DISV, "0")
info(autosaveFields, "VAL")
}

record(calc, "$(user):UCrTcrLimitUsRd")
{
field(CALC, "((A / 10^-6) / 300000000)")
field(INPA, "$(user):UCrTcrLimRd.VAL CP MS")
field(EGU,  "us")
field(SDIS, "$(user):StartUpOn.VAL CP MS")
field(DISV, "0")
}

This only works for the graphical user interface CSS (I am not able to modify the Pv value in the gui) but, if I use CAPUT, I can modify the PV value. 

Is there any way to completely block setting function?

Thanks in advance, Adrián.
