Thanks, that helps a lot.
FYI
The device support in this case is not talking to some hardware, but is itself a watchdog server, written as ChimeraTK application and build against the ChimeraTK-EPICS adapter. It was initially developed for OPC-UA.

Subject: RE: Process at Init of mbbo-record
I'm not sure why RVAL is 0 for record 4, but 3 for records 3 and 5.
But the first place to look is your device support. You are using some custom device support for these records, and that could be setting RVAL incorrectly. You can add some debugging in the functions in device support to print the value of RVAL.
The asyn device support for mbbo, for example, reads the current value from the hardware into the RVAL field. If your device support does something like that then that could explain RVAL not being 3 as you expect.

Hi Patrick,
I forgot to CC tech-talk on my original reply.
Your st.cmd got stripped out by the mail system, please rename to st.cmd.txt before attaching.
Please use the details=5 flag on the dbpr commands, e.g.
dbpr Tst/4Config/targetStream 5
Did you check carefully for any warnings or errors in the iocsh output when starting the IOC?
Mark

Hi,
the db-file and the start-script, where it is loaded, is attached. I have also attached the req files used to set the record via save_restore, just in case. The dbpr output is:
epics> dbpr Tst/4Config/targetStream
ASG : DESC: DISA: 0 DISP: 0
DISV: 1 NAME: Tst/4Config/targetStream RBV : 0
RVAL: 0 SEVR: NO_ALARM STAT: NO_ALARM TPRO: 0
VAL : 3
I have also looked at the mbbo record loaded afterwards:
epics> dbpr Tst/4Config/logLevel
ASG : DESC: DISA: 0 DISP: 0
DISV: 1 NAME: Tst/4Config/logLevel RBV : 0
RVAL: 3 SEVR: NO_ALARM STAT: NO_ALARM TPRO: 0
VAL : 3
and as you can see, it is processed correctly at init, as is the targetStream record before:
epics> dbpr Tst/3Config/targetStream
ASG : DESC: DISA: 0 DISP: 0
DISV: 1 NAME: Tst/3Config/targetStream RBV : 0
RVAL: 3 SEVR: NO_ALARM STAT: NO_ALARM TPRO: 0
VAL : 3
and afterwards:
epics> dbpr Tst/5Config/targetStream
ASG : DESC: DISA: 0 DISP: 0
DISV: 1 NAME: Tst/5Config/targetStream RBV : 0
RVAL: 3 SEVR: NO_ALARM STAT: NO_ALARM TPRO: 0
VAL : 3
Regards,
Patrick

Can you show:
- The database file
- The commands to load it 8 times
- The output of the following command at the iocsh, where (record) is the name of the 5'th record loaded.
dbpr (record) 5

Subject: Process at Init of mbbo-record
Hi,
I observe some odd behaviour. I have changed a longout record to an mbbo record, either with passive scan and pini=1. This record is loaded eight times with different macros. After the change to mbbo, the 5th instance of this record is not processed during init (VAL is set, RVAL is 0). This is true, even if the sequence, in which the different instances are loaded, are switched. Could this be a timing issue of some sort?
Greetings
Patrick
