Revision 3.1 - 139 - March 2010
Using a test segment (with the types of wiring components and at least one field device
to be used on the project), connect the segment to every port on the H1 interface or
linking devices (including spares) at the terminal block designated for the field wiring or
system cable downstream of the fieldbus power supply.
Observe that the device(s) is recognized on the Host system live list.
If power supplies or power conditioners with switchable terminators are used, verify that
the terminator switch is in the correct position.
Verify that the DC voltage and LAS signal is within rated limits of the power supply.
Commentary:
Verification of DC voltage and LAS signal may be accomplished with hand-held test
equipment, a portable oscilloscope, or with advanced diagnostic modules (online or
offline).
A8.3.2 Redundancy Switch-over Test Procedure
Where redundant FOUNDATION fieldbus interface cards and/or power supplies are used,
the redundant operation of each component shall be tested. The test shall verify that
automatic fail over shall not cause an upset (i.e., signal bumps, loss of operator view,
mode changes, etc.). All FOUNDATION fieldbus interface cards and power supplies shall
be tested.
All failure alarms shall be tested and signed off.
A8.3 Field Device Operation
If separate Device Integration Testing is not performed prior to FAT, then use the
procedures described in Device Integration (Section A8.2) above.
A8.3.4 Data Reconciliation
For each configured parameter residing in the FOUNDATION fieldbus devices (e.g. in TB,
AI, PID or AO block), complete the following steps:
• Verify the appropriate scale and engineering units are configured as needed in
both the AI (AO) Function Block and in the Transducer Block.
• Verify that the scale and engineering units are correct and consistent for the
FOUNDATION fieldbus device and the associated faceplate, graphics and trends.
• Verify that all engineering units in the Transducer Block are consistent with the
project standards. In particular, engineering units used for diagnostic and not for
graphics may be overlooked and require extensive rework if not detected at the
device integration test.
• Simulate a process variable equal to half the scale and verify.
• The process variable appears correctly within the PV parameter field of the AI
(AO) block.
