You should have something like

=== /etc/gpib.conf ===
interface {
        minor = 0
        board_type = "ni_pci"
        name = "L0"
        pad = 0
        sad = 0
        timeout = T3s

        eos = 0x0a
        set-reos = yes
        set-bin = no
        set-xeos = no
        set-eot = yes

        master = yes
}
======================

in /etc/gpib.conf. You need to use something else than 0 for the pad (primary 
address) setting of the board, if your device itself really has address 0. 
Verify your setup with ibtest!

This looks wrong to me. You have to pass the "L0" name to the database. Are 
you sure your device is at address 0? For your device at GPIB address 15, it 
should look like

dbLoadRecords("../../db/devPSM6003.db","P=PSM6003:,PORT=L0,ADDR=15")

You are missing
PSM6003_DBD += drvLinuxGpib.dbd
in PSM6003App/src/Makefile. See my lengthy post in your other thread.

That final message regarding CA server beacon address looks suspicious, but 
can maybe ignored.

Again: make sure you can talk to the device using ibtest first.
