The S800 I/O is distributed modular I/O which communicates with numerous
controllers over a Advant Fieldbus 100 (AF 100), PROFIBUS-DP or directly.
The S800 I/O provides easyinstallation of the I/O modules and process cabling. It is
highly modularized and flexible so that I/O modules can be combined to suit many
applications.The S800 I/O can be mounted in many configurations to fit most
requirements.

This book provides a general description of the S800 I/O and reference information
about equipment common to all types of installations, for example power supplies
and Modulebus components. It provides overall instructions for site planning and
installation, start-up and shutdown procedures, and information regarding capacity
and performance. This book is not intended to be the sole source of instruction for
the S800 I/O system.
This chapter provides introductory and background information including
guidelines how to find information in the manual related documentation and a
product and functional overview of the S800 I/O.
Chapter 2 guides in installation of the I/O system including:
• Guidelines for planning the installation of the product.
• Information how to set up the equipment. It includes safety regulations,
handling and unpacking instructions, inspection and assembly procedures,
cable routing and connections, setup procedures, etc. Common instructions as
well as instructions directed to specific subsystem are given. Activities prior to
power up are described.
• Shut-down procedures. In addition to safety regulations, the basic shut down
procedures are given. You should know how to shut-down the product if initial
power up has problems.
• Start-up procedures. In the set-up section the conditions and the preparation for
start are discussed, and here you can find basic power up procedures, such as,
how to apply power to and initialize the I/O system.
• Product Verification. Initial determination that the I/O is functional.
Chapter 3 will give you the information needed to obtain the desired function.
The main information is structured as follow:
• Design considerations and guidelines are given.
• Capacity and performance.
Chapter 4 discusses the different start modes and operating modes of the I/O.
Chapter 5 focus is on fault finding supported by built in diagnostics and use of
system status displays in operator station and LEDs on I/O hardware units.

The S800 I/O is a modular I/O system. The modular system allows for easy
configuration of the I/O type and size.
An 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 module (FCI) and
up to 12 I/O modules. I/O clusters 1 to 7 consist of a ModuleBus Modem and up to
12 I/O modules. I/O clusters 1 to 7 are connected to the FCI though a fiber optic
expansion of the ModuleBus. An S800 I/O Station can have up to 24 I/O modules.
This means that an I/O Station can have a maximum of 384 digital channels or a
maximum of 192 analog channels.
An S800 I/O Station base cluster can also consist of redundant FCIs to provide
greater availability of communications between the Advant Controller and the
ModuleBus.
Each I/O cluster can be divided in groups using ModuleBus extension cables
between the groups. The maximum length of the electrical ModuleBus of an I/O
cluster is 2.5 meters (8.2 ft.) including extension cables. The factory made extension
cables which plug into the cable adaptors are available in lengths of 0.3, 0.6 and
1.2 m (1, 2 and 4 ft.). The maximum length of the optical ModuleBus expansion is
dependent on the number of ModuleBus Modems. The maximum length between
any two clusters is 15m (50ft.) with plastic fiber and 200m (667ft) with HCS glass
fiber. Factory made optical duplex cables (plastic fiber) are available in lengths of
1.5, 5 and 15 m (5, 16.7 or 50 ft.).

Each I/O module is installed on a Module Termination Unit (MTU). The first MTU
with its I/O module connects to the FCI or a cluster’s ModuleBus Modem and then
each of the remaining MTUs connect to the previous MTU. With redundant FCIs,
the ModuleBus connects to the ModuleBus Interconnection Unit.
An FCI communicates with its I/O modules over the ModuleBus. The ModuleBus
can be divided into 8 clusters, one base cluster and up to 7 I/O cluster. The base
cluster consists of the FCI and I/O modules. Additional I/O clusters (1 to 7) consist
of a ModuleBus Modem and I/O modules. The ModuleBus Modems are connected
via optical cables to an optional ModuleBus Optical Port module on the FCI.
Within a cluster the ModuleBus is made up of increments that are integrated into
each MTU. The FCI and ModuleBus Modems have a ModuleBus outlet connector
to connect to an MTU. An MTU has a bus inlet and a bus outlet connector. By
adding, on the DIN rail, an MTU to a FCI or a ModuleBus Modem, the bus is
automatically expanded up 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.
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 only operational 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 with all active circuitry allocated to the I/O
module. The ModuleBus requires a terminator to be installed after the last MTU of
an I/O cluster.

The CI810 Fieldbus Communication Interface (FCI) module is a configurable
communication interface which performs operations such as signal processing,
gathering of various supervision information, OSP handling and configuration of re-
inserted I/O modules. The FCI connects to the controller by way of the Advant
Fieldbus 100 (AF 100) twisted pair segment. The FCI supports redundant media
configurations.
