11 DEV_TYPE Manufacturer’s model number associated with the resource - used
by interface devices to locate the DD file for the resource.
12 DEV_REV Manufacturer revision number associated with the resource - used
by an interface device to locate the DD file for the resource.
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.
14 GRANT_DENY Options for controlling access of host computers and local control
panels to operating, tuning, and alarm parameters of the block.
Not used by device.
15 HARD_TYPES The types of hardware available as channel numbers.
16 RESTART Allows a manual restart to be initiated. Several degrees of restart
are possible. They are the following:
1 Run – is the passive state of the parameter
2 Restart resource – not used
3 Restart with defaults – intended to reset parameters to default
values, i.e. their value before any configuration was done
4 Restart processor – does a warm start of CPU

capable.
22 MEMORY_SIZE Available configuration memory in the empty resource. To be
checked before
attempting a download.
23 NV_CYCLE_T Minimum time interval specified by the manufacturer for writing
