Advant Fieldbus 100 is the communications bus
between the I/O stations and Controllers
The Fieldbus Communication Interface (FCI) device
contains the interface to the fieldbus (e.g. AF 100),
ModuleBus interface and power regulators. The FCI
module can manage 24 I/O devices (up to 12 directly
and to the others in 1 to 7 I/O clusters).
FCI plus up to 12 directly connected I/O modules.
An extension of the I/O Station's ModuleBus connected
to the FCI by fiber optic connections. Up to 12 I/O
devices per cluster.
A complete I/O device consists of one MTU and one I/O
module.
Is the active, electronic and signal conditioning part of an
I/O device.
An I/O station consists of one or two FCI(s), 1-7 I/O
clusters and up to 24 I/O devices.
Is an incremental, electrical or optical, bus for
interconnection of I/O devices.
Is used when extending the electrical ModuleBus (within
the max. 2 meters).
The Module Termination Unit is a passive base unit
containing process terminals and a part of the
ModuleBus.
Outputs Set as Predetermined. A user configurable
action on an output module when communications is lost
to the FCI or Controller
Resistance Temperature Detector
Sequence Of Events. Time stamping of status changes
for digital inputs.
