1.2 FloBoss 107 Overview
A 32-bit microprocessor-based electronic flow computer, the FB107
electronically measures, monitors, and manages flow. This economical
flow computer reliably and accurately performs flow calculations,
temperature measurements, and data archival.
Note: You configure the functionality of the FB107 and monitor its
operation using a personal computer (PC) running ROCLINK 800
(“ROCLINK 800”) software.
The FB107 can measure up to four meter runs through a variety of
devices, such as an orifice plate, turbine meter, or other pulse-generating
devices. Meter inputs may also use analog transmitters. For multiple
differential pressure-run applications, you can add an optional MultipleVariable Sensor (MVS) module to provide an interface to remote MVS
transmitters.
The FB107 performs minute, hourly, daily, and minimum / maximum
historical data archival for standard history and a configurable time
interval archival for extended history. As the electronic solution to
replace traditional paper charting, the FB107 records the corrected flow
for differential or pulse counts and stores the data.
The FB107 computes flow for both volume and energy. It provides onsite functionality and supports remote monitoring, measurement, data
archival, communications, and control. It stores the results of the flow

m (2000 ft).
The EIA-485 (RS-485) drivers are designed for true multi-point
applications with multiple devices on a single bus.
Note: COM1 is labeled 485 on the CPU.
Use COM1 to monitor or modify the FB107 from a remote site, using a
host or ROCLINK 800. COM1 also supports the log-on security feature
of the FB107 if you enable the security on COM1 using ROCLINK 800.
COM1 sends and receives messages using the ROC or Modbus slave and
host protocol. COM1 is capable of initiating a message in support of
Spontaneous-Report-by-Exception (SRBX) alarming.
Default values for the EIA-485 (RS-485) communications are: 19,200
baud rate, 8 data bits, 1 stop bit, no parity, 10 millisecond key-on delay,
and 10 millisecond key-off delay. The maximum baud rate is 115.2 Kbps.
EIA-232 (RS-232) Serial
Communications
COM2
COM2 allows for EIA-232 (RS-232) asynchronous serial
communication protocols with baud rates from 300 to 115.2 K, host
serial interface. COM2 provides standard single-ended data
transmission over distances of up to 15 meter (50 feet).
Use COM2 to monitor or alter the FB107 from a remote site, using
ROCLINK 800. COM2 also supports the log-on security feature of the
FB107 if you enable the security on COM2 using ROCLINK 800.
COM2 sends and receives messages using the ROC or Modbus slave or
host protocol. COM2 is capable of initiating a message in support of
Spontaneous-Report-by-Exception (SRBX) alarming.
Default values for the EIA-232 (RS-232) communications module are:
19,200 baud rate, 8 data bits, 1 stop bit, no parity, 10 millisecond key-on
delay, and 10 millisecond key-off delay. The maximum baud rate is 115.2
Kbps.
Note: When you install a communication module in slot 2, the
firmware redirects communications port (COM2) on the CPU to
the type of module installed in slot 2. Configure COM2 based on
the type of communication module installed in slot 2.

1-10 General Information Revised May-2018
1.3.8 Built-in Resistance Thermal Device (RTD)
The FB107 supports a direct input from a resistance thermal device (RTD)
sensor to measure flowing temperature. An RTD temperature probe
typically mounts in a thermowell on the meter run. The RTD has a
measurement range of 40 to 400°C (40 to 752°F). The RTD is located
on the CPU.
1.3.9 Built-in Loop Output Power
Using ROCLINK 800, you can configure the I/O on the CPU module to
set the loop output power to 10 volts dc or 24 volts dc:
▪ The 24-volt setting of the loop output power is used to power
devices that require 24 volts dc to ground, allowing the external
device to send the FB107 a 4 to 20 mA signal based on pressure,
temperature, level, and such.
▪ The 10-volt setting of the loop output power is intended for low
power transmitters. The loop current is designed to deliver 80 mA
to power two field devices that connect back to the two analog
inputs.
Note: The CPU I/O assembly uses the CPU’s loop power output and
ground connections.
The I/O module only supports 24 volts dc loop output power. When 10
volts is selected, the loop output power will be 10V+ depending on input
power supply
1.3.10 Optional Inputs and Outputs
The input/output (I/O) options for the FB107 provide terminals for
expanded monitoring and control applications. Use I/O to drive a sampler
or odorizer, open a valve, or monitor an additional analog input.
You can order the expanded 6-point I/O as an:
▪ I/O assembly that mounts directly on the CPU module (optional I/O
assembly).
▪ I/O modules that mount in the I/O slots.
Both configurations provide terminations for six points of I/O and both
provide the same selections for I/O. You can configure five of the six
points of I/O using ROCLINK 800 software.
The six points of I/O consists of:
▪ Two analog inputs (AI) or discrete inputs (DI).
▪ One analog output (AO) or discrete output (DO).
▪ One discrete output (DO).
▪ Two pulse inputs (PI) or discrete inputs (DI).
FloBoss 107 Flow Manager Instruction Manual
Revised May-2018 General Information 1-11
Adding an expansion rack to the FB107 base unit increases I/O by four
slots for a total of six slots of I/O. The FB107 supports up to six I/O
modules and one CPU I/O assembly.
Other available I/O modules include the 8-point AI/DI, the 6-point
AO/DO, the Discrete Output Relay (DOR) module, the HART module,
the Pulse Input (PI) module, the MVS I/O module, and the Resistance
Temperature Detector (RTD) module (see Chapter 4, Inputs and
Outputs). The Multi-Variable Sensor (MVS), Dual Variable Sensor
(DVS), and Pressure module (PM) are factory-installed options (see
Chapter 5, Sensors and Transducers).
You can install I/O modules in slots 1 through 3 on the FB107 base unit
and in slots 4 through 6 on the expansion rack. If you install a
communications module in slot 1, you can install an I/O module in slot 7.
You can use current analog inputs of 4 to 20 mA when you select the
250-ohm resistor in the AI configuration using ROCLINK 800.
Note: See Chapter 4, Inputs and Outputs, for more information on
FB107 I/O modules.
1.3.11 Optional Communication Modules – COM3
Optional communication modules provide the ability to send and receive
data through COM3. The COM3 port is capable of initiating a message in
support of Spontaneous-Report-by-Exception (SRBX) alarming.
You can install communication modules in slots 1 or 2 on the base unit.
Installing a communications module in slot 1 on the base unit activates
the COM3 communications port. Installing a communications module in
slot 2 redirects the CPU’s communications port (COM2) to the type of
module installed in slot 2.
The FB107 accommodates following types of communication modules:
▪ EIA-485 (RS-485) serial communication protocols with baud rates
from 300 to 115.2 Kbps to provide standard differential data
transmissions over distances of up to 1220 meter (4000 feet).
▪ EIA-232 (RS-232) serial communication protocols with baud rates
from 300 to 115.2 Kbps, host serial interface to provide standard
single-ended data transmission over distances of up to 15 meter (50
feet).
▪ Enhanced Communication module (ECM) provides an Ethernet and a
USB 2.0 port.
▪ Dial-Up Modem module provides communication over a Public-
Switched Telephone Network (PSTN) up to 2400 bps bits per second
(bps).
FloBoss 107 Manager Instruction Manual
1-12 General Information Revised May-2018
COM3 can communicate with other devices using ROC or Modbus host
and slave protocols. The firmware can automatically detect ROC or
Modbus slave protocols.
Note: See Chapter 5, Communications, for more information on FB107
communication modules.
1.3.12 Optional Multi-Variable Sensor (MVS)
The optional Multi-Variable Sensor (MVS) module provides differential
pressure, static pressure, and temperature inputs to the FB107 for
differential pressure flow calculation.
You can install only one MVS module in the FB107. You can install the
MVS module in slots 1 through 3 on the base unit or in slots 4 through 7
on the expansion rack, regardless of the position of any other type of
module.
The MVS module provides current-limited power and EIA-485 (RS-485)
communications to external remote MVS transmitters. The FB107
supports six remote transmitters with up to four meter runs. See Chapter
6, Sensors and Transducers, for more information.
1.3.13 Optional Integral Sensors
The FB107 supports a Dual Variable Sensor (DVS) or a Pressure module
(PM), either of which attaches to the bottom of an FB107 enclosure and
connect to the DVS port on the FB107’s base unit. See Chapter 6,
Sensors and Transducers, for more information.
1.3.14 Optional License Key
The optional application license key provides extended functionality,
such as the use of various user programs. The FB107 supports up to six
different user programs. For example, you need to install a license key
with the proper license in the FB107 to run User C programs.
1.3.15 Optional Enclosures
You can place your FB107 in weather-tight enclosures. Enclosures
protect the FB107 electronics from physical damage and harsh
environments. You can choose between a polycarbonate (see Figure 1-5),
or a steel (see Figure 1-6) enclosure.
Note: If you have a PIM attached to a polycarbonate enclosure or a
DVS attached to a steel enclosure, adjust the height dimensions
accordingly.

(FB107:LCD).
1.4 Firmware
The firmware makes extensive use of configuration parameters, which
you manage using ROCLINK 800 software. The firmware contained in
flash ROM on the processor board determines the FB107’s functionality.
The firmware provides a complete operating system for the FB107, and is
field-upgradeable using a serial connection such as the LOI port.
Firmware includes:
▪ Input and output database.
▪ Historical database.
▪ Event and alarm log database, holding up to 240 alarms and 240
events.
▪ Applications, such as PID, AGA, and FST.
▪ Real-time clock.
▪ Determining task execution.
▪ 1992 AGA-3 flow calculations (with user-selectable AGA8
compressibility Detail, Gross 1, or Gross 2).
▪ 1996 AGA-7 flow calculations (with user-selectable AGA8
compressibility).
▪ ISO5167-2003 flow calculations.
▪ ROC or Modbus host or slave (ASCII or RTU).
▪ Establishing and managing communications.
▪ Communications based on the ROC protocol or Modbus slave and
host (ASCII or RTU) protocol for use with EFM applications.
▪ Alarm call-in to host for Spontaneous-Report-By-Exception (SRBX).
▪ Standard and Extended History.
▪ Self-test capability.
▪ User level security.
The FB107 provides the functions required for a variety of field
automation applications. Designed for expandability, the FB107
monitors, measures, and controls equipment in a remote environment.
You can use the FB107 for:
▪ Applications requiring flow computation.
▪ Logic and sequencing control using a user-defined Function Sequence
Table (FST).
▪ Closed-loop (PID) control capabilities (requires optional I/O module
or CPU I/O assembly).
▪ Custom User C application support.
FloBoss 107 Flow Manager Instruction Manual
Revised May-2018 General Information 1-15
Real-Time Operating
System (RTOS)
The FB107 firmware uses a pre-emptive, multi-tasking, message-based
real-time operating system (RTOS). Tasks are assigned priorities and,
at any given time, the operating system determines which task will run.
For instance, if a lower priority task is executing and a higher priority
task needs to run, the operating system suspends the lower priority task,
allows the higher priority task to run to completion, then resumes the
lower priority task’s execution.
TLP
The FB107 reads data from and writes data to data structures called
“points.” A “point” is a ROC protocol term for a grouping of
individual parameters (such as information about an I/O channel) or
some other function (such as a flow calculation). Points are defined by
a collection of parameters and have a numerical designation that
defines the type of point.
The logical number indicates the physical location for the I/O or the
logical instance for non-I/O points within the FB107. Parameters are
individual pieces of data that relate to the point type. The point type
attributes define the database point to be one of the possible types of
points available to the system.
A sample TLP might be analog input (T), rack location B1 (L), and
Engineering Units (P).
Together, these three components—the type (T), the logical (L), and the
parameters (P)—identify specific pieces of data that reside in an FB107
database. Collectively, this three-component address is often called a
TLP.
1.4.1 History Points
The FB107 saves history to either of two databases: Standard or Extended
History. You can configure the number of entries/logs available to
Standard (maximum of 100) and Extended History (maximum of 25).
History for meter runs includes the Averaging Techniques as well as
accumulation per second and accumulation per minute.
You can select the number of history points to archive, the sample
interval in minutes (for Extended or Standard History) or seconds (for
Extended History only), the number of days to archive, and whether to
log history data at the beginning or the end of the period.
History is one block of memory divided into two areas, one for Standard
History and one for Extended History. Standard History uses all of the
memory that it requires for the configured number of points. Extended
History only receives the surplus memory Standard History does not use.
Standard History archival properties include:
▪ Up to 100 points of minute data from the last 60 minutes.
▪ Up to 100 points of hourly data for 35 days.
▪ Up to 100 points of daily data for 35 or 60 days.
▪ Min / max historical data for today and yesterday.
FloBoss 107 Manager Instruction Manual
1-16 General Information Revised May-2018
Extended History archiving provides a monitoring resolution for the
FB107 that is similar to a chart recorder. You can configure Extended
History to archive up to 25 history points with archiving intervals at 1, 2,
3, 4, 5, 10, 12, 15, 20, 30, or 60 second or minute intervals.
Minute Historical
Log
The FB107 has a 60-minute historical log for every history point. The
Minute Historical Log stores the last 60 minutes of data from the
current minute. Each history point has Minute Historical Log entries,
unless the history point is configured for FST-controlled logging.
Hourly Historical
Log
The FB107 has a total of 35 days of hourly historical logs available for
every history point. The Hourly Historical Log is also called the
Periodic database. Normally, the Hourly Log is recorded at the
beginning of every hour, although you can configure it for either the
beginning or end of every hour. The exceptions are FST Minute and
FST Second logging.
The time stamp for periodic logging consists of the month, day, hour, and
minute. The exception is for FST Second logging, in which the time
stamp consists of the day, hour, minute, and second.
Daily Historical
Log
The FB107 has a total of 35 or 60 daily historical logs for every history
point. The Daily Log is recorded at the configured contract hour every
day with a time stamp that is the same as the Hourly Log. Each history
point has daily historical log entries, unless the history point is
configured for FST-controlled logging.
Min / Max Historical
Log
The Min / Max database displays the minimum and the maximum
values for the database points over a 24-hour period for today and
yesterday. You can view the Min / Max historical, but not save it to
disk.
Extended History Log
The FB107 has configurable archive times that, in turn, determine the
number of entries. You can configure Extended History to archive up
to 25 history points with archiving intervals at 1, 2, 3, 4, 5, 10, 12, 15,
20, 30, or 60 second or minute intervals.
1.4.2 Alarm Log
The alarm log contains the change in the state of any alarm signal that has
been enabled for alarms. The system alarm log has the capacity to
maintain and store up to 240 alarms in a “circular” log. The alarm log has
information fields that include time and date stamp, alarm clear or set
indicator, and either the tag name of the point or a 14-byte detail string in
ASCII format.
In addition to providing functionality for appending new alarms to the
log, the alarm log allows host packages to request the index of the most
recently logged alarm entry. Alarm logging is available internally to the
system, to external host packages, and to FSTs.
FloBoss 107 Flow Manager Instruction Manual
Revised May-2018 General Information 1-17
Note: ROCLINK 800 does not store alarm logs to the flash ROM when
you select the Save Configuration function.
The alarm log operates in a circular fashion with new entries overwriting
the oldest entry when the buffer is full. The alarm log provides an audit
history trail of past alarms. The system stores the alarm log separately
from the event log to prevent recurring alarms from overwriting
configuration audit data.
1.4.3 Event Log
The event log contains changes to any parameter within the FB107 made
through the protocol. This event log also contains other FB107 events,
such as power cycles, cold starts, and disk configuration downloads. The
event log provides an audit history trail of past operation and changes.
The event log has information fields that include point type, parameter
number, time and date stamp, point number (if applicable), the operator
identification, the previous or current parameter values, and either the tag
name of the point or a 14-byte detail string in ASCII format.
The system event log has the capacity to maintain and store up to 240
events in a circular log. The event log operates in a circular fashion with
new entries overwriting the oldest entry when the buffer is full. The event
log provides an audit trail history of past operation and changes. The
system stores the event log separately from the alarm log to prevent
recurring alarms from overwriting configuration audit data.
In addition to providing functionality for appending new events to the
log, the event log allows host packages to request the index of the most
recently logged event entry. Event logging is available internally to the
system, to external host packages, and to the FST.
Note: ROCLINK 800 does not store event logs to the flash ROM when
you select the Save Configuration function.
The FB107 has the ability to limit the AGA calculation-related events to
only critical events. Selecting Enabled in the Limit Meter Events field on
the Meter Setup’s Advanced tab (Meter > Setup) keeps the system from
filling the event log with unnecessary events. The events not logged
include temperature, pressure, Reynolds number, and warnings for orifice
diameter, pipe diameter, and beta ratio.
1.4.4 Security
The FB107 permits device-based security. You can define and store a
maximum of 16 log-on identifiers (IDs). In order for the unit to
communicate, the log-on ID supplied to ROCLINK 800 software must
match one of the IDs stored in the FB107. This security feature is enabled
by default on the Local Operator Interface port (Security on LOI). You
FloBoss 107 Manager Instruction Manual
1-18 General Information Revised May-2018
can configure security protection on COM1, COM2, and COM3, but this
security is disabled by default.
1.4.5 I/O Database
The I/O database contains the I/O points the operating system firmware
supports, including the system analog inputs and variables, MultiVariable Sensor (MVS) values, communications, and smart application
modules. The firmware automatically determines the point type and point
number location of each installed module. It then assigns each input and
output to a point in the database and includes user-defined configuration
parameters for assigning values, statuses, or identifiers. The firmware
scans each input, placing the values into the respective database point.
These values are available for display and historical archiving.
1.4.6 Function Sequence Tables (FST)
The FB107 supports FST user programmability. You can develop four
FST programs with a maximum length of 3000 bytes each. You configure
the number of FST lines per execution cycle in ROCLINK 800.
The FST code resides in static RAM and is backed up to flash memory
when you issue the Save Configuration function through ROCLINK 800.
Note: You must first enable FSTs (Configure > Control > FST
Registers) in order to make them available.
1.4.7 PID Control
The PID Control applications firmware provides Proportional, Integral,
and Derivative (PID) closed-loop control for a FB107, which enables the
stable operation of a feedback control loop that employs a regulating
device, such as a control valve. The FB107 supports eight PID control
loops and requires an optional CPU I/O assembly or I/O module.
The firmware sets up an independent PID algorithm (loop) in the FB107.
The PID loop has its own user-defined input, output, and override
capability.
A PID control loop maintains a process variable at setpoint. If PID
override control is configured, the primary loop is normally in control of
the regulating device. When the change in output (user-selectable) for the
primary loop becomes lesser or greater than the change in output
calculated for the secondary (override) loop, the override loop takes
control of the regulating device. A typical example is for flow control
with a pressure override loop.
Note: You must first enable PID control loops (ROC > Information) in
order to make them available for use.
FloBoss 107 Flow Manager Instruction Manual
Revised May-2018 General Information 1-19
1.4.8 Spontaneous-Report-By-Exception (SRBX) Alarming
The SRBX functionality allows you to set up a communications port that
enables the FB107 to contact the host computer when specified alarm
conditions exist. To configure SRBX alarming, each communications
port must have the SRBX parameter enabled, each point must have the
alarming parameter enabled, and points must have an SRBX parameter
(SRBX on Set, SRBX on Clear, or SRBX on Set & Clear) selected.
SRBX occurs over a serial line if the host is set up for receiving fieldinitiated calls.
1.4.9 Softpoints
Softpoints are global data storage areas that any FB107 application can
use. For example, a softpoint may store the results of a specified FST
calculation or store an intermediate result of a specified value an FST or
user program acquires. Softpoints consist of a tag identifier, one integer
value, and twenty floating values. Thirty-two softpoints provide storage
for over 704 variables.
1.4.10 Opcodes
Use the Opcode Table to group data being polled for more efficient
communications. You can assign parameters from different point types
can be assigned to the opcode table data points, which can substantially
reduce the number of polls from a host computer. The FB107 supports
eight opcode tables, each with 44 values.
1.4.11 Pass Through Communications
By using the FB107 communications ports, Pass Through
Communications mode allows one unit to receive data and then pass it
through to other devices connected on any other communications port.
For example, the host communicates via a radio on the FB107 COM2
port. Other FB107 units can then be connected via EIA-485 (RS-485) on
the COM1 port of the first FB107, and then all the FB107 units can use
the one radio to communicate to the host.
Note: The Device Group of the FB107 receiving the data must match the
Device Group of the FB107s to which the data is passed. The
Device Group is located on the Information screen (ROC >
Information).
1.4.12 ROC and Modbus Protocols
The FB107 has the capability to communicate with other devices using
ROC or Modbus protocols. The firmware can automatically detect the
two protocols (ROC or Modbus) at baud rates of up to 115.2 Kbps bps.
FloBoss 107 Manager Instruction Manual
1-20 General Information Revised May-2018
ROC protocol supports serial communications to local or remote devices,
such as a host computer.
An FB107 can act as a Modbus host or slave device using either Remote
Terminal Unit (RTU) or American Standard Code for Information
Interchange (ASCII) modes. This allows you to easily integrate the
FB107 into other systems. Extensions to the Modbus protocol allow the
retrieval of history, event, and alarm data in Electronic Flow Metering
(EFM) Measurement applications.
Notes:
▪ The LOI port only supports ROC or Modbus slave protocols.
▪ The FB107 auto-detects either ROC or Modbus slave protocol
messages on all comm ports. To enable Modbus host on a particular
comm port, you must select Modbus host as the port owner. As a
Modbus host, the comm port then does not support ROC protocol
messages.
1.4.13 User C Programs
Optionally, you can order custom application programs developed in User
C to provide functionality not included in the firmware, such as
calculations for steam and custom communication drivers. Examples of
custom User C programs include:
▪ Flow calculation.
▪ Properties calculations.
▪ Communications programs.
▪ Special applications.
You can transfer licenses for User C programs to the FB107 using
ROCLINK 800’s License Key Administrator function (Utilities >
License Key Administrator).
1.5 ROCLINK™ 800 Configuration Software
ROCLINK 800 Configuration software is a Microsoft® Windows-based
program that runs on a PC and enables you to monitor, configure, and
calibrate the FB107.
Many of the configuration screens, such as meters, I/O, and PIDs, are
available while ROCLINK 800 is off-line. This enables you to configure
the system while either on-line or off-line with the FB107.
The Local Operator Interface (LOI local port) provides a direct link
between the FB107 and a PC. The LOI port uses a DB9 connector with
standard EIA-232 (RS-232C) pinout. With a personal computer running
ROCLINK 800, you can locally configure the FB107, extract data, and
monitor its operation.
FloBoss 107 Flow Manager Instruction Manual
Revised May-2018 General Information 1-21
Remote configuration is possible from a host computer using a serial
communications line. You can duplicate configurations and save them to
a disk. In addition to creating a backup, this feature is useful when you
are similarly configuring multiple FB107s for the first time, or when you
need to make configuration changes off-line. Once you create a backup
configuration file, you can load it into an FB107 with the Download
function (File > Download).
Access to the FB107 is restricted to authorized users with correct user ID
and password.
You can build custom displays for the FB107 in ROCLINK 800 that
combine both graphic and dynamic data elements. The displays can
monitor the operation of the FB107 either locally or remotely.
You can archive historical values for any numeric parameter in the
FB107. For each parameter configured for historical archiving, the system
keeps time-stamped minute, periodic, and daily data values as well as
yesterday’s and today’s daily minimum and maximum values.
You can collect history values from the FB107 using ROCLINK 800 or
another third-party host system. You can view history directly from the
FB107 or from a previously saved disk file. For each history segment,
you can configure the number of periodic history values archived, the
frequency of archiving the periodic values, the number of daily values
archived, and the contract hour.
ROCLINK 800 can create an EFM (Electronic Flow Measurement) report
file that contains all configuration, alarms, events, periodic and daily
history logs, and other history logs associated with the meter runs in the
FB107. This file then becomes the custody transfer audit trail.
Use ROCLINK 800 to:
▪ Configure and view input/output (I/O) points, flow calculations, meter
runs, PID control loops, system parameters, and power management
features.
▪ Retrieve, save, and report historical data.
▪ Retrieve, save, and report events and alarms.
▪ Perform two-, three-, four-, or five-point calibration on analog inputs
and Multi-Variable Sensor (MVS) inputs.
▪ Perform two-, three-, four-, or five-point calibration on RTD inputs.
▪ Implement user security.
▪ Create, save, and edit graphical displays.
▪ Create, save, edit, and debug Function Sequence Tables (FSTs) of up
to 3000 bytes.
▪ Set up communication parameters.
▪ Configure Modbus parameters.
▪ Update the firmware.

1.6 Product Electronics
This section describes the FB107 electronic components.
1.6.1 Real-Time Clock
The real-time clock provides the FB107 with the time of day, month,
year, and day of the week, as well as real-time stamping of the database
values. The real-time clock automatically switches to backup power when
the FB107 loses primary input power. Backup power for the real-time
clock is adequate for a period in excess of one-year with no power
applied to the FB107.
The internal super-cap provides backup for the data and the real-time
clock when the main power is not connected. The super-cap has a oneyear minimum backup life with the battery installed and no power applied
to the FB107.
Note: The real-time clock uses the super-cap to keep the current time
when you replace the lithium battery.
1.6.2 Diagnostic Monitoring
The electronics board has five diagnostic inputs incorporated into the
circuitry for monitoring system integrity. Access these analog inputs
using the I/O function of ROCLINK 800 software (Configure > I/O).

1.6.3 Automatic Self Tests
The FB107 becomes active when input power with the proper polarity
and startup voltage (typically set greater than 8.0 volts) is applied to the
PWR+ / PWR connector (provided the power input fusing/protection is

operational). The battery and logical voltage tests ensure that the FB107
is operating in the optimum mode.
The software arms the watchdog timer every scan period. If the timer is
not armed in 6 seconds, the software automatically resets.
1.6.4 Low Power Mode
Under pre-defined conditions, the FB107 uses a sleep mode to conserve
power.
During sleep mode, the CPU powers down, although I/O continues to
accumulate. The FB107 enters sleep mode after one minute of inactivity
on the communication ports. You can disable sleep mode, which ensures
that the FB107 stays awake all the time. You configure this option (which
is Disabled by default) on the Sleep Mode field on the CPU module’s
Advanced tab.
The FB107 wakes from sleep mode occurs when it receives either a:
▪ Timed interrupt from the real-time clock.
▪ Signal from one of the communication ports.
1.7 Flow Measurements
Gas and liquid calculation methods include:
▪ AGA and API Chapter 21 compliant for AGA linear and differential
meter types.
▪ AGA3 – Differential for gas.
▪ AGA7 – Pulse (ISO 9951) for gas.
▪ AGA8 – Compressibility for Detailed (ISO 12213-2), Gross I (ISO
12213-3), and Gross II for gas.
▪ ISO 5167 – Differential.
FB107 firmware completes full calculations every second on the
configured meter run (up to four) for AGA3, AGA7, AGA8, and ISO
5167.
Note: You must enable meter runs and adjust the number of available
meters (ROC > Information > Device Information screen >
Points tab, AGAs field) so that additional meter runs become
available. You can also optimize a system by disabling unused
meters or PIDs.
The primary function of the FB107 is to measure flow in accordance with
the 1992 American Petroleum Institute (API), International Standards
Organization (ISO), and American Gas Association (AGA) standards.
The primary inputs used for AGA3 flow measurement function are
differential pressure, static pressure, and temperature. The differential and
static pressure inputs are sampled once per second. The temperature

1-24 General Information Revised May-2018
input, which is sampled and linearized once per second, comes from an
RTD probe.
AGA3 calculations conform to the methods described in American Gas
Association Report No. 3, Orifice Metering of Natural Gas and Other
Related Hydrocarbon Fluids. Based on the second and third editions, the
calculation method is 1992 AGA3.
The primary inputs used for AGA7 flow measurement are pulse input (PI)
counts, static pressure, and temperature. The pulse input counts are
acquired from a rotary meter, turbine meter, or other pulse-generating
devices. The static pressure inputs come from the pressure transducers,
and the temperature input is read from an RTD probe. The AGA7
calculations conform to methods described in American Gas Association
Report No. 7, Measurement of Natural Gas by Turbine Meters (2006),
and use the AGA8 method for determining the compressibility factor.
The ISO5167-2003 firmware calculates gas flow. Measurement of fluid
flow occurs through pressure differential devices inserted in circular
cross-section pipes running full.
The AGA8 method calculates the compressibility factor based on the
physical chemistry of the component gasses at specified temperatures and
pressures.
1.8 Security Gateway
For enhanced data security when using an IP/Ethernet connection,
Remote Automation Solutions recommends adding an industrial router
with VPN and firewall security. Recommended solutions include the
MOXA EDR-810, the Hirschman Eagle One, or the Phoenix mGuard
rs4000 (or equivalents). An example of how to install one of these
devices to the RTU/flow computer can be found in the Remote
Automation Solutions MOXA® Industrial Secure Router Installation
Guide (part D301766X012). For further information, contact your Local
Business Partner or the individual vendor’s website.
