Revision 3.1 - 141 - March 2010
A8.4 Site Acceptance Testing Requirements
Unless specifically warranted, a full re-test of the FAT is not necessarily required. A
representative sample of components should be chosen to repeat some of the testing
from FAT. An example would be to test only one port on each H1 interface or linking
device in order to ensure that the system had been properly reassembled.
A8.5 Segment Testing/Commissioning Procedure
Each segment, including spares, shall be operationally tested by live connection of at
least one but preferably all devices. The device shall be connected to the terminal block
designated for the field wiring or system cable downstream of the fieldbus power-
conditioning module (FPPS).
A8.5.1 Segment Check
For each selected FOUNDATION fieldbus segment to be tested, complete the following
steps:
• Complete segment testing and commissioning.
• Test/confirm that the Host system and devices have the same firmware/software
revisions.
• Test/confirm that all H1 interface cards used in the Host system are the same
firmware/software revision.
• Check that the relevant segment communication parameters are correct and that
the macrocycle duration has been set for each network.
• Check that the power-conditioning module (generally an FPPS) operates correctly
and that a failure is communicated to the Host system.
• Check that the network/segment recovers from a short circuit.
• Measure the overall current consumption.
• Check that the FOUNDATION fieldbus Host system interface module operate
correctly and that a failure is identified by the Host system.
• Check that the Back-up LAS is functioning and is executing the correct schedule.
This only applies if Back-up LAS will be applied (i.e., for segments with CIF); in all
other cases, no Back-up LAS (BLAS) is required and this test can be omitted.
• Monitor stable operation for at least 12 h.
Optional:
• Check the communication load under stable (no download) condition. A load of
less than 70% will be required. The Host system might supply this information or
alternatively, an external tool such as the National Instruments Bus Monitor may
be used.
• Ensure sufficient spare capacity is provided by connecting two extra fieldbus
devices and observing proper operation of the full segment.
Commentary:
Some of the segment check may have previously been tested (such as verification of
the operation of H1 interfaces), and therefore may be omitted by the user.
