Index
Number Parameter Description
13 DD_REV Revision of the DD associated with the resource - used by an interface
device to locate the DD file for the resource. The DD_REV specifies the
minimum DD revision that is compatible with the device (within the
same device revision). A vendor can release an updated DD with the
DD_REVISION higher than the DD_REV. This allows a vendor to release
an updated DD files set that will be compatible with an existing device
revision in the field. The host can always load a higher DD_REVISION for a
given DEV_REV/DEV_REVISION.
As per Foundation requirement the DD_REV will always be 01.

to operating, tuning, and alarm parameters of the block. Not used by

i.e. their value before any configuration was done
