Device Application Process (DAP) blocks
Resource Block (RB)
Overview
This block contains data that is specific to the hardware that is associated with the resource. All data is modelled as Contained, so
there are no links to this block. The data is not processed in the way that a function block processes data, so there is no function
schematic.
This block contains and manages all the diagnostic info available from the 266 PdP in compliance with the NAMUR NE107
recommendations.
The parameters relating the NAMUR NE107 requirements are those with the prefix FD_xxx
Each root error is mapped into one of the four NAMUR NE107 classifications (Failure, Maintenance, Out of Specifications and
Function Check) triggering the transmission of the relating Alarm to the hosts.
This parameter set is intended to be the minimum required for the Function Block Application associated with the resource in
which it resides. Some parameters that could be in the set, like calibration data and ambient temperature, are more appropriately
part of their respective transducer blocks.
The ITK_VER parameter identifies the version of the Interoperability Tester used by the Fieldbus Foundation in certifying the
device as interoperable.
Block Mapping
Idx Parameter Description / Range / Selections / Notes
BLOCK_OBJ
In the Block Object data structure, there are different items describing the block characteristics. Execution period,
Number of parameters in the block, the DD Revision, Profile Revision, View Objects characteristics and so on
ST_REV
The revision level of the Static data associated with the Function Block. The revision level is incremented each time a
static parameter value (S – under Storage) in the block is changed.
TAG_ DESC The user description of the intended application of the block
STRATEGY The strategy field can be used to identify grouping of blocks. This data is not checked or processed by the block.
ALERT_KEY The identification number of the plant unit. This information may be used in the host for sorting alarms, etc.
MODE_BLK
TARGET AUTO / OOS The selectable modes by the operator.
ACTUAL The mode the block is currently in.
PERMITTED AUTO / OOS Allowed modes that the target may take on
NORMAL AUTO The common mode for the Actual.
BLOCK_ERR
This parameter reflects the error status associated with the hardware or software components associated with a
block. It is a bit string, so that multiple errors may be shown.
enabling the Simulation.
SEE its correspondence to Device root errors in the
dedicated section of this manual
“The Resource Block MODE_BLK_ACTUAL = Out of
Service.
Also, the Actual mode of all the Funct.Blocks is
forced to OOS”
RS_STATE State machine of the function block application.
TEST_RW Read/Write test parameter – used only for conformance testing.
DD_RESOURCE String identifying the tag of the resource, which contains the Device Description for this resource.
MANUFAC_ID Manufacturer Identification number
used by an interface device
to locate the DD file for the
resource
DEV_TYPE Manufacturer’s model number associated with the resource
DEV_REV Manufacturer’s revision number associated with the resource.
DD_REV Revision of the DD associated with the resource
GRANT_DENY
Options for controlling access of host computer and local control panels to operating, tuning and alarm parameters
of the block.
HARD_TYPES Scalar Input The type of Hardware available as channel numbers
