Hey again,I found the issue. All records have a db-link in their SDIS field to a bo record.
This bo record switches on/off the power supply of the device, so if this is set to 0 communication with the device does not work.
The record was set to 1 during initialization but still in UDF_ALARM state which was causing the LINK_ALARM for all other records.

Hey all, I have a strange behaviour I haven't seen before. In my IOC all records are set to STAT = LINK_ALARM and SEVR = INVALID.I checked the code of the device support, that is used, but there are only conditions when a record is set to READ_ALARM or WRITE_ALARM.Is there any condition in the record processing itself, where a record can be set to LINK_ALARM?Base 7.0.4.1 is used. The records have a DB_LINK in their SDIS field and some have a FLNK. Cheers, Florian
