Hi,

I've set up a softMotor record that converts between coordinate systems
according to some user-definable parameters according to some soft-ioc
ai records using a CALC record. That works all nice and pretty, however
what I did not get to work is to also set the soft-limits of the
softMotor dynamically to the corresponding ai record values.

This is my Soft-Motor and ai-record definition:

record(motor,"$(IOC):$(powerMotor)")
{
    field(DTYP,"Soft Channel")
    field(OUT,"$(IOC):$(convertPowerToWp).A  PP MS")
    field(RDBL,"$(IOC):$(convertWpToPower).VAL  NPP MS")
    field(URIP,"Yes")
    field(STOO,"$(IOC):$(wpMotor).STOP  PP MS")
    field(DINP,"$(IOC):$(wpMotor).DMOV  NPP MS")
    field(MRES,0.001)
    field(RRES,1)
    field(PREC,3)
    field(DHLM,"$(IOC):$(MaxPower).VAL CP MS")
    field(DLLM,"$(IOC):$(MinPower).VAL CP MS")
    field(TWV,".1")
    field(RTRY,"0")
    field(EGU,"W")
}

record(ai,"$(IOC):$(MinPower)")
{
    info(autosaveFields, "VAL")
    field(DESC,"Minimum Power")
    field(VAL,"0")
    field(FLNK,"$(IOC):$(convertWpToPower) PP MS")
    field(EGU,"W")
}

record(ai,"$(IOC):$(MaxPower)")
{
    info(autosaveFields, "VAL")
    field(DESC,"Maximum Power")
    field(VAL,"1")  
    field(FLNK,"$(IOC):$(convertWpToPower) PP MS")
    field(EGU,"W")
}

And the errors I get:

Can't set "simManip:Pump:Power.DHLM" to "simManip:Pump:MaxPower.VAL CP
MS" No digits to convert
Can't set "simManip:Pump:Power.DLLM" to "simManip:Pump:MinPower.VAL CP
MS" No digits to convert

I would appreciate any advice on this.

Thanks, Laurenz
