Subject: | PINI field not working with modbus |

Hello all.
I have an analog in record for reading a modbus register from a device. The record is defined as follows:
record(ai,
"${BL}:${H}:${EQ}:TargetVoltRead"){
field(DESC,
"Voltage set on target [V].")
field(DTYP,
"asynInt32")
field(EGU,
"V")
field(ASLO, 0.01)
field(INP,
"@asyn(NEG_EMODBUS_1_1_Rd_VTarget,0,1000)MODBUS_DATA")
field(SCAN,
"1 second")
}Which reads fine. However, if i set the PINI field to YES and the scan to passive:
record(ai,
"${BL}:${H}:${EQ}:TargetVoltRead"){
field(DESC,
"Voltage set on target [V].")
field(DTYP,
"asynInt32")
field(EGU,
"V")
field(ASLO, 0.01)
field(INP,
"@asyn(NEG_EMODBUS_1_1_Rd_VTarget,0,1000)MODBUS_DATA")
field(SCAN,
"Passive")
field(PINI,
"YES")
}i get only 0 as value when cagetting the PV. Am i doing something wrong? Thanks in advance.
