SIMM mode for mbbiDirect record

[Vladimir Sirotenko <sirotenko@fnal.gov>]

Hi,

It looks like SIMM mode for mbbiDirect records does not work in epics 3.14 
generating "Invalid" severity state.
Simple setup is shown below:

record(longin,"CTL_VS/SET") {
field(DTYP, "Soft Channel")
field(SCAN, "1 second")
field(FLNK, "CTL_VS/MBBI")
field(VAL,"1")
field(PINI,"YES")
}
record(mbbiDirect,"CTL_VS/MBBI") {
field(DTYP, "Raw Soft Channel")
field(INP, "2")
field(SCAN, "Passive")
field(NOBT, "16")
field(SHFT, "0")
field(SIMM, "YES")
field(SIOL, "CTL_VS/SET")
field(FLNK, "CTL_VS/LONGIN")
}
record(longin,"CTL_VS/LONGIN") {
field(DTYP, "Soft Channel")
field(INP, "3")
field(SCAN, "Passive")
field(SIMM, "YES")
field(SIOL, "CTL_VS/SET")
}

The record CTL_VS/MBBI is always in "Invalid" state while longin 
CTL_VS/LONGIN is ok
Did anyone see it?
