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?

affirmative. The links are resolved when you call iocInit.

everything I want.
you mean one big (.db) database. It will work the other way so not needed.
