Revision 3.1 - 105 - March 2010
• Sufficient devices are available to configure all typical networks. A selection of
representative FOUNDATION fieldbus segments is available. Purchaser shall confirm
the selected segments as being representative of the networks being installed. In
addition, segments with the highest device load, communication load, and complex
strategies shall be included.
• Selected FOUNDATION fieldbus networks/segments are prepared (but no devices
connected). The hardware infrastructure will be checked (e.g. power, signal
strength, noise and grounding).
• FOUNDATION fieldbus simulation function for parameters in field devices can be
enabled to simulate process conditions and to evaluate alarm settings, but is not
recommended because the simulation feature can be left on inadvertently. Use the
manual feature of the Function Blocks and enter a value. Simulation shall be turned
off as a default for commissioning. Some asset management systems will report
simulation-on as an alert/alarm.
• Sufficient external terminations of the type used by the project are available.
• Final cabling and junction boxes are not used. Representative connections will be
made. The final infrastructure will be tested during the commissioning.
Commentary:
For especially long or complicated networks, the network should be simulated using reels of
cable in the factory or a cable simulator, in order to more closely emulate expected field
conditions.
9.3 Device Integration Testing Requirements:
Device Integration Testing verifies that the selected FOUNDATION fieldbus field devices and
wiring components are truly compatible with the Host system (and software revision) selected
and with each other. Sufficient operation time should be allowed to ensure stability of all
devices.
Device Integration Tests are especially useful in the early stages of a project when selecting
the Host system and field devices to be used and developing configuration templates as well
as control strategies. If Device Integration Tests are thorough enough, the need for testing of
devices at the Factory Acceptance Test may be reduced or eliminated.
By conducting Device Integration Testing as early in a project as possible, the user will have a
firm basis for the selection of field devices and wiring components from the technical
standpoint as well as from the commercial aspect. Potential problems can be brought to light,
and work-arounds developed early, to avoid problems during installation in the field. It also
provides an excellent opportunity for training of personnel in testing and maintenance of the
devices.
Commentary:
The Interoperability Test Kit procedures provided by the Fieldbus Foundation ensures that the
devices function and communicate properly per the standards, but cannot account for the
