Preface
The IMFBS01 Field Bus Slave (FBS) Module supplies 15 field
inputs to the INFI 90®strategic process management system. It
links process data and communication from Bailey-Fischer &
Porter smart transmitters to all multi-function processors
(MFP), or the IMMFC03, IMMFC04 and IMMFC05 multi-func-
tion controller (MFC) modules. The field bus I/O module oper-
ates in one of three modes: FSK field bus mode (FSK digital
data and communication), FSK analog point-to-point mode
(analog inputs with or without FSK digital communication
available) and baseband analog point-to-point mode (analog
inputs with or without baseband communication available).
This instruction explains the FBS features, specifications and
operation. It explains how to set up and install an FBS module,
and covers troubleshooting procedures.
The system engineer or technician using the FBS module
should read and understand this instruction before installing
and operating the module. In addition, a complete understand-
ing of the INFI 90 system is beneficial.

OVERVIEW
I-E96-302B 1 - 1
SECTION 1 - INTRODUCTION
OVERVIEW
The IMFBS01 Field Bus Slave (FBS) Module inputs 15 chan-
nels of analog or frequency shift keyed (FSK) digital signals to
the multi-function processor (MFP) or multi-function controller
(MFC) module. It is a dedicated module that connects field
equipment and Bailey-Fischer & Porter smart transmitters to
controlling modules (MFP/MFC) within the INFI 90/
Network 90®system.
The module also provides a signal path from an INFI 90 opera-
tor interface, such as an operator interface station (OIS) or
configuration and tuning terminal (CTT), through an MFC or
MFP module and I/O interface to Bailey-Fischer & Porter
smart transmitters. Figure 1-1 shows how the FBS module fits
within the INFI 90 system.
The FBS module communicates with the Bailey-Fischer & Por-
ter line of FSK digital transmitters in a field bus or
point-to-point configuration. Communication is also available
with Bailey-Fischer & Porter baseband smart transmitters
(point-to-point).
INTENDED USER
Installation and application personnel should have a solid
background in electronic instrumentation and process control.
They should be familiar with proper grounding and safety pro-
cedures for electronic instrumentation. Operators should have
a knowledge of the process and should read and understand
this instruction before placing the module in operation.
HARDWARE DESCRIPTION
The FBS module is an intelligent module, with on-board micro-
processor, memory, analog-to-digital converter and communi-
cation circuitry. The module is a single printed circuit board
that occupies one slot in a module mounting unit (MMU). Two
captive latches on the module faceplate secure it to the module
mounting unit.
The module has three card edge connectors for external signals
(transmitter inputs and communication), system communica-
tion (I/O expander bus) and power. The module receives input
through a cable connection to a termination unit (TU) or termi-
nation module (TM). Wiring from the field devices connect to
terminal blocks on the termination unit or termination module.

INTRODUCTION
HARDWARE APPLICATION
1 - 2 I-E96-302B
®
The circuit board contains four jumpers that allow selecting
the mode of operation and communication. A dipswitch setting
holds the I/O expander bus address of the module.
HARDWARE APPLICATION
The FBS module interfaces analog and digital signals from field
devices to the MFP or MFC module. The FBS module can inter-
face Bailey-Fischer & Porter FSK smart transmitters and base-
band smart transmitters, conventional transmitters and
standard analog inputs (four to 20 milliamps, zero to one VDC,
one to five VDC, zero to five VDC, zero to ten VDC and ±10
VDC).
The FBS module can operate in one of three modes: FSK field
bus mode, FSK analog point-to-point mode, or baseband analog
point-to-point mode. In the FSK field bus mode, a single

FEATURES
I-E96-302B 1 - 3
two-wire input (bus) links a maximum of 15 FSK smart trans-
mitters. All inputs (process data and module to transmitter
communication) are in the frequency shift keyed format and
share the field bus. Refer to the NTFB01 Field Bus Slave Ter-
mination Unit instruction for specific limitations on field bus
communications. All field devices must be Bailey-Fischer &
Porter FSK smart transmitters when using this mode.
In the FSK analog point-to-point mode, the FBS module can
interface up to 15 discrete analog process inputs from FSK
smart transmitters and communicate (digitally) with those
transmitters. Additionally, the FBS module can interface a
mixture of baseband smart transmitters, conventional trans-
mitters and other external analog inputs while operating in
this mode. These devices can input only process data to the
FBS module; they cannot communicate to the module. In
point-to-point operation, each device is individually wired to
the analog input termination unit or module.
Baseband analog point-to-point mode allows the FBS module
to emulate the IMASI02 Analog Input Slave Module. In this
mode, the module can interface Bailey-Fischer & Porter FSK
smart transmitters, baseband smart transmitters, conven-
tional transmitters and other external analog inputs. Only the
Bailey-Fischer & Porter baseband smart transmitters can
communicate to the FBS module while it is operating in this
mode. The FBS module can interface any mixture of these
devices.
FEATURES
The design of the FBS module, as with all INFI 90 modules,
allows for flexibility in creating a process management system.
The module supports Bailey-Fischer & Porter FSK digital
smart transmitters, baseband smart transmitters, conven-
tional transmitters and standard voltage or current inputs. The
option of selecting one of three FBS module operating modes is
available.
The FSK digital capability eliminates conversion errors and
increases process control accuracy. Access is always available
to the real time process status. In the field bus mode, all infor-
mation (including the process variable) is transmitted digitally
between the FBS module and the field devices.
The FBS module stores process data, control commands and
transmitter configuration data in memory. It works to restore
communication with a transmitter if a communication failure
occurs. Upon restoring communication with a failed transmit-
ter, the FBS module checks the transmitter configuration
before the controlling module (MFP/MFC) resumes updating
the process control.

SECTION 2 - DESCRIPTION AND OPERATION
INTRODUCTION
This section explains the operation of the FBS module. The
module does two major tasks. It provides an interface by which
the controlling module (multi-function processor or
multi-function controller module (MFP/MFC)) can input analog
process data from external devices or smart transmitters. It
also serves as a communication link between the INFI 90 con-
trol system and field devices.
The FBS module has three modes of operation: FSK field bus
mode, FSK analog point-to-point mode and baseband analog
point-to-point mode.
SYSTEM OPERATION
The digital interface, made up of the FBS module and the con-
trolling module, provides a communication path between an
INFI 90 operator interface and Bailey-Fischer & Porter smart
transmitters as shown in Figure 2-1. Commands can be sent
from an operator interface to change transmitter parameters or
to rerange a transmitter output. In return, the transmitters
send process and status data to the operator interface through
the FBS module and controlling module (MFP/MFC). The con-
trolling module communicates with the FBS module over the
I/O expander bus.
MFP/MFC Module
The controlling module (MFP/MFC) directs the operation of the
smart transmitters and holds their operating strategy. The
configuration of function code 133 (smart transmitter defini-
tion) in the controlling module determines the operating strat-
egy of each smart transmitter. Function code 132 (analog
input/slave) reads the inputs of the FBS module. Operation

begins when the controlling module is placed in the execute
mode with function code 132, and optionally with function
code 133, in its configuration. When the controlling module
enters the execute mode, it downloads the operating strategy to
the FBS module.
IMFBS01 Module
Upon receiving initialization from the controlling module
(MFP/MFC), the FBS module stores that information in mem-
ory and checks the configuration of each input channel. If all
input channels check good, operation begins. If the FBS mod-
ule detects a configuration error, that error appears in the
module status report.
Under normal operation, the controlling module sends trans-
mitter commands and requests process input data and status
information from the FBS module. The FBS module continu-
ously reads each input channel, does the necessary conver-
sions and stores the data in memory. When the controlling
module makes a request for data, the FBS module sends it the
most current information that it has in memory.
If a communication failure with one of the smart transmitters
occurs, the FBS module works to restore communication while
continuing normal operation. It checks the transmitter config-
uration upon restoring transmitter communication and normal
process control continues.
Smart Transmitter
FSK smart transmitters communicate with the FBS module at
a rate of 9600 baud. Baseband smart transmitters communi-
cate at a rate of 600 baud. To prevent changes to the transmit-
ter configuration during normal operation, the module sends a
security byte to the transmitter at the beginning of each trans-
mitter communication.
The security byte triggers the smart transmitters to take con-
figuration commands only from the module, unless the FBS
module turns the transmitter off-line. The security byte locks
out configuration commands from other operator interface
devices such as a smart transmitter terminal (Types STT02
and STT02E). All devices can monitor the transmitter. When
the transmitter receives the security byte, it sets a two-minute
timer. The timer counts down until another command is
received to reset the timer. Normally the timer does not expire
because the module resets it before the two-minute timer
expires.
NOTE:
Both the Types STT02 and STT02E terminals are referred to
in this instruction. Differences are noted as they occur.

In the event a module failure occurs, the transmitter timer
expires after two minutes. The transmitter resets itself and
receives configuration commands from other devices such as
the smart transmitter terminal.
IMFBS01 MODES OF OPERATION
The FBS module has three operating modes: FSK field bus
mode, FSK analog point-to-point mode and baseband analog
point-to-point mode (analog I/O input emulation mode). Mode
selection is through FBS circuit board jumpers. Function code
132 must be configured in the MFP or MFC device for every five
analog inputs.
FSK Field Bus Mode
The FSK field bus mode allows pure digital communication
with Bailey-Fischer & Porter FSK smart transmitters on a bus
(Fig. 2-1). Examples of the FSK line of smart transmitters are
the PTS and BCN smart pressure transmitters, EQN smart
temperature transmitter and Type TBN580 smart pH/ORP
smart transmitter. In the FSK field bus mode, all transmitters
reside on the field bus. The process variable signal from each
transmitter is sent to the FBS module in an FSK digital format.
Since all 15 input channels are FSK digital, no channel can
accept an analog input signal when the module is in this mode.
The NTFB01 terminals provide a bus to connect the FSK smart
transmitters to the FBS module. Function codes 132 and 133
must be configured in the MFP or MFC device for every five
analog inputs from each transmitter.
FSK Analog Point-to-Point Mode
The FSK analog point-to-point mode enables the FBS module
to input standard analog inputs, such as four to 20 milliamp
signals, and use digital communication with Bailey-Fischer &
Porter FSK style smart transmitters (Fig. 2-2). In this mode,

the analog signal from each smart transmitter goes to an indi-
vidual input channel (point-to-point). Because the inputs are
analog point-to-point, the FBS module can interface any com-
bination of devices while it is in this operating mode. For exam-
ple, in addition to FSK smart transmitters, baseband smart
and conventional transmitters can input process data but can-
not communicate with the FBS module. The NTAI05 termina-
tion unit or NIAI04 termination module provides point-to-point
termination. Dipshunts select the type of input signal for each
channel. Function code 133 must be configured in the MFP or
MFC device for every five analog inputs from each FSK device.
Baseband Analog Point-to-Point Mode
The baseband analog point-to-point mode emulates the opera-
tion of the IMASI02 Analog Input Slave Module, which was the
predecessor to the FBS module. When operating in this mode,
the FBS module can interface any combination of Bailey -Fis-
cher & Porter FSK smart transmitters, baseband smart trans-
mitters, conventional transmitters and other analog inputs.
The FBS module inputs analog process data point-to-point and
communicates to the baseband smart transmitters (Fig. 2-3).
Examples of these transmitters are the BC smart pressure
transmitter, EQ2 smart temperature transmitter and smart
pH/ORP/pION transmitter. The NTAI05 termination unit or
NIAI04 termination module provides point-to-point termina-
tion. Dipshunts or dipswitches select the type of input signal
for each channel. Function codes 132 and 133 must be config-
ured in the MFP or MFC device for every five analog inputs
from each baseband transmitter.

IMFBS01 OPERATION
The FBS module can be divided into five functional blocks.
Figure 2-4 shows a block diagram of the IMFBS01 module. The
five functional blocks of the FBS module are:
•Module inputs/outputs (I/O).
•Communication circuitry.
•Microprocessor and control logic.
•Analog-to-digital converter.
•I/O expander bus interface.
The FBS module interfaces Bailey-Fischer & Porter smart
transmitters to the controlling module (MFP/MFC). It does this
by encoding and decoding communication and data that is
going to and coming from the transmitters. Under normal oper-
ation, the FBS module continuously inputs, converts and
stores data so that it is available to the controlling module. The
controlling module requests process data, transmitter status,
does calibrations and sends operating commands through the
I/O expander bus interface.
