 Sure enough.
Any record in your whole system will have access to any other record in
your system.

If the target of a link is not found locally (on the same IOC), the
database will use Channel Access to find the target.
Chapter 5 in the AppDevGuide is your friend.

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
