System Configuration
The following instruments are required for use with Fieldbus devices:
Power supply
Fieldbus requires a dedicated power supply. It is recommended that
current capacity be well over the total value of the maximum current
consumed by all devices (including the host). Conventional DC cur-
rent cannot be used as is.
Terminators
Fieldbus requires two terminators. Refer to the supplier for details of
terminators that are attached to the host.
Field devices
Connect the field devices necessary for instrumentation.
SVI FF has passed the interoperability test conducted by The Fieldbus
Foundation. In order to properly start Fieldbus, use the devices to
satisfy the requirements of the above test.
Host
Used for accessing field devices. A dedicated host (such as DCS) is
used for an instrumentation line while dedicated communication
tools are used for experimental purposes.
Cable
Used for connecting devices. Refer to
Fieldbus Technical Information
(TI 38K3A01-01E) for details of instrumentation cabling. Provide a
cable sufficiently long to connect all devices. For field branch
cabling, use terminal boards or a connection box, as required.
Termination processing depends on the type of device being
deployed. For SVI FF, use an M4 screw terminal claw. Some hosts
require a connector.
Refer to Masoneilan when making arrangements to purchase the recommended equipment.
The number of devices that can be connected to a single bus and the cable length vary
depending on system design.
When constructing systems, both the basic and overall design must be carefully considered to
allow device performance to be fully exploited.
