Hej Ralph,

I think it is the same-

camonitor, second round:
IOC:m6-OpenClutch 2021-05-27 15:51:06.243006 Closed UDF INVALID
IOC:m6-OpenClutch.UDF 2021-05-27 15:51:06.243006 0 UDF INVALID
IOC:m6-OpenClutch.STAT 2021-05-27 15:51:06.243006 UDF UDF INVALID
IOC:m6-OpenClutch.SEVR 2021-05-27 15:51:06.243006 INVALID UDF INVALID

[snipped warnings because of multihomed]
And this is dbpr IOC:m6-OpenClutch 10

    Asyn-Experts,

    I am chasing an interesting problem.
    For a motor, we have a clutch that can be opened under very
    special conditions, say service mode.


    We define it like this:
    [...]
    The alarm seem to go away, if the record is processed one more time.
    (by disconnecting the IOC from the controller and re-establishing the
    connection).

    Is this a know phenomena ?
    Anything that can be done ?


How does the setup behave when using Channel Access?
(To see if it is a problem on the ASYN side or the QSRV side of the database.)

Cheers,
~Ralph
