9 Device Application Process (DAP) Blocks

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 JDF300 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.
