Yes.
But you are not restricted to the same IOC, records in one IOC can
access records in other IOCs as well. There are some restrictions, but
records can both read and write PVs in other IOCs.

Subject: DataBase question
Hey guys,
I'm building a database to ramp a magnet given inputs from an Agilent
34970 MUX and output to an Agilent 3631 Voltage programmer. I've got the
drivers and device support working for the MUX and programmer and would
like to create a database (and separate application) that can access the
AI and AO records from the devices and and perform calculations. My
question is: Do records loaded in the same IOC have access to each
others PVs? For instance if I :
dbLoadRecords("db/devAG34970.db",args)
dbLoadRecords("db/devAG3631.db",args)
to load the AI and AO records for the devices, can I have a third
record,
dbLoadRecords("db/MagnetCtrl.db",args)
that contains calc records that have inputs from pvs defined in the
devAG records? Alternatively, do I have to define one big record that
includes everything I want.
Cheers,
Andrew
