A S800 I/O Station can consist of a base cluster and up to 7 additional I/O clusters. The base
cluster consists of a Fieldbus Communication Interface and up to 12 I/O modules.
I/O cluster 1 to 7 consist of an Optical Modulebus modem and up to 12 I/O modules.
A S800 I/O Station can have a maximum of 24 I/O modules. I/O cluster 1 to 7 are connected to
the FCI module through an optical expansion of the Modulebus.

The Fieldbus Communication Interface module communicates with its I/O modules over the
Modulebus. The Modulebus can support up to 8 clusters, one base cluster and up to 7 I/O clusters.
The base cluster consists of a communication interface module and I/O modules. An I/O cluster
consist of an Optical Modulebus modem and I/O modules. The Optical Modulebus modems are
connected via optical cables to a optional Modulebus Optical port module on the communication
interface module. The maximum length of the Optical Modulebus expansion is dependent of the
number of Optical Modulebus modems. The maximum length between two clusters is 15 m
(50 ft.) with plastic fibre and 200 m (667 ft.) with glass fibre. Factory made optical cables (plastic
fibre) are available in lengths of 1.5, 5 and 15 m (5, 16 or 49 ft.). The Optical Modulebus
expansion can be build up in two ways, a ring or a duplex communication.
Within a cluster the Modulebus is made up of increments integrated into each Module
Termination Unit (MTU). Each communication interface module and Optical Modulebus modem
has a Modulebus outlet connector to connect to a MTU. A MTU has a bus inlet and a bus outlet
connector. By adding, on the DIN rail, a MTU to a communication interface module or an Optical
Modulebus modem, the bus is automatically expanded, offering optional further expansion of
MTUs to a maximum of 12 MTUs. Unique position codes are automatically assigned to each
MTU as the bus is expanded. An inserted I/O module is assigned the unique position identity of
its MTU. Through the incremental bus design the physical size of an S800 I/O installation is
directly proportional to the number of installed MTUs.
MTUs and their associated I/O modules can within a cluster be set up in two or three physically
separated groups with extension cable adaptors which fit to the bus outlet and inlet connectors of
communication interface modules, Optical Modulebus modem and MTUs. The factory made
extensions cables which plug into the cable adaptors are available in lengths of 0.3, 0.6 and 1.2 m
(1, 2 or 4 ft.), allowing together with up to 12 I/O modules, for a total bus length of 2.5 meters
(8.2 ft.).
The S800 I/O modules can be inserted and removed from MTUs without disturbing system
operation. The physical lock which locks an I/O module to its MTU allows I/O module removal
only when the lock is in its unlock position. The locking mechanism also acts as a logic lock so
that an I/O module is operable only when the lock is in the locked position. If the lock is in its
unlocked position, output channels are de-energized and I/O modules can be inserted/removed
without need to remove system or field power.
The MTUs are totally passive units and all active circuitry is allocated to the I/O module.

The Fieldbus Communication Interface (FCI) modules have an input for one 24 V d.c. power.
