Subject: Hex constant as input to longin record?
From: Russell Kackley <[email protected]>

Section 2.3 (on pg. 15) of the EPICS Record Reference Manual (R3.13)
states: "A constant ... can be an integer value in whatever format (hex,
decimal, etc.) ...". I would like to use a hex constant as input to a
longin record, but can't get it to work. Has anyone used hex constants
successfully? We are using EPICS R3.13.4.

Here is the record description:

record(longin,"test:test") {
    field(DESC,"long input record")
    field(SCAN,"Passive")
    field(PINI,"NO")
    field(PHAS,"0")
    field(EVNT,"0")
    field(DTYP,"Soft Channel")
    field(DISV,"1")
    field(SDIS,"0.000000000000000e+00")
    field(DISS,"NO_ALARM")
    field(PRIO,"LOW")
    field(FLNK,"0.000000000000000e+00")
    field(INP,"0x0001")
    field(EGU,"volts")
    field(HOPR,"0")
    field(LOPR,"0")
    field(HIHI,"0")
    field(LOLO,"0")
    field(HIGH,"0")
    field(LOW,"0")
    field(HHSV,"NO_ALARM")
    field(LLSV,"NO_ALARM")
    field(HSV,"NO_ALARM")
    field(LSV,"NO_ALARM")
    field(HYST,"0")
    field(ADEL,"0")
    field(MDEL,"0")
    field(SIOL,"0.000000000000000e+00")
    field(SIML,"0.000000000000000e+00")
    field(SIMS,"NO_ALARM")
}

Here is the record in the IOC:

VAL: 0              

Note that EPICS thinks the INP field is a CA_LINK, not a CONSTANT. Any
help or advice would be appreciated. Thanks.
