Hi,
While setting up an mbboDirect record with an Acromag XT1111 Binary I/O module, I observe the behavior that only the LSB of my 6-bit mbboDirect bit bank is being changed when the EPICS value is changed. Is modbus function "6" the appropriate one to use for the mbboDirect data type? The drvModbusAsynConfigure instruction I am using is:
drvModbusAsynConfigure("C1ISCAUX_BIO02","c1iscaux_bio02",0,6,0,4,0,1,"Acromag")
and the EPICS record itself is set up as:
grecord(mbboDirect,"C1:LSC-CM_REFL1_BITS")
{
field(DESC,"REFL1 gain bits")
field(DTYP,"asynUInt32Digital")
field(OUT,"@asynMask(C1ISCAUX_BIO02 0 0x1)")
field(NOBT,"6")
field(OMSL,"closed_loop")
field(DOL,"C1:LSC-CM_REFL1_SET")
field(PINI,"YES")
}
I'm also wondering if it is possible to have mbboDirect bits that are grouped together from two separate hardware Binary I/O PLCs?
thanks,
gautam
