Security

To secure your valuable process and data, the FB2200

provides multi-level role-based access, user account

authentication, and password encryption.

The system administrator can set a minimum

password length (up to 20 characters) that

accommodates lower case, upper case, numbers, and

symbols, as well as configure a user lock-out feature

that locks out invalid users after a defined number of

failed login attempts.

Additionally, the DNP3 protocol lends itself to an added

layer of security through Secure Authentication (SA).

SA version 5 (SAv5) is available in the FB2200 Flow

Computer as a selection in the firmware. SAv5

authenticates the devices which significantly improves

resistance to outside influence.

Configuration Software

Emerson’s FBxConnect tool is a Microsoft® Windows®

based tool that enables you to easily monitor,

configure, service, and calibrate the FB2200 flow

computer. Designed for ease-of-use, FBxConnect

provides at-a-glance monitoring, quick access to

commonly performed tasks, and a guided

configuration process to quickly get your

measurement up and running.

The wizard-driven approach simplifies configuration

and ensures that you only need to enter the required

data once. Whether you are an experienced engineer

or a new technician, you can be confident

configuration is done correctly the first time.

FBxConnect runs on a Windows PC or tablet. You

connect securely to the flow computer using one of its

serial ports, Ethernet port, or optionally through the

FBxWifi wireless connection. For more information,

refer to product data sheet FBxConnect (D301789X012).

Power Options

You can power the FB2200 with an external DC power

supply or from an internal rechargeable battery linked

to a solar system. The internal battery can power the

device for up to 45 days depending on the application.

Note: The internal battery option is available with Class

1 Div 2 approval only.

Housing Options

The FB2200 has two housing options, both suitable for

hazardous area installation. The corrosion-resistant

aluminum and the fiberglass enclosures each protect

the electronics from physical damage and harsh

environments. The enclosures include a battery box to

house a rechargeable battery for use with solar

systems and an optional radio mounting bracket. The

lockable door also provides a viewing window for the

optional LCD. The door can also be fitted with an

optional security switch, to generate an alarm each

time the door is opened.

Hazardous Area Certifications

The FB2200 has the following Global Hazardous Area Approvals:

▪ North American certification for Class I Division 2 Groups A, B, C, and D.

▪ ATEX and IECEx certification for Ex ec, Zone 2 hazardous locations.

The flow computer also supports two user periodic

logs, the duration or period of each is user selectable

between 1 second and 200 hours. The first user

periodic logs include 10 parameters over 4.000 periods

and the second contains 20 parameters over 500 periods.

The flow computer with FBxConnect provides pre

formatted EFM reports for hours and days. The format

of the reports can be .csv, .pdf, or secure .pdf.

In addition to the above reports, the flow computers

can produce FLOWCAL-compliant .cfx files through the

FBxConnect tool as well as calibration reports which

contain U.S. Bureau of Land Management specific parameters.

▪ Hourly logs

▪ Daily logs

▪ Weekly logs

▪ Monthly logs

62 days or 1500 records

12 months or 365 records

12 months or 52 records

60 months or 60 records

Note: This is only the initial default history. With the

flexible history design, the number of variables

and the time duration for different periodic

logs can be adjusted to meet the application requirement.

The FB2200 features expanded and flexible history

capability to ensure measurement confidence and

meet the increasing demands for secure data.

The flow computer has four standard periodic logs

available providing hourly, daily, weekly, and monthly

history. These logs can contain up to 110 variables

including flow weighted average data, totals, and gas

composition. For averaging, the FB2200 supports

either flow weighted or flow dependent which can be

linear or formulaic.

For gas meter averages, you can choose between flow

dependent linear per API Chapter 21.1 (2013) or flow

dependent formulaic, flow-weighted linear, or flow

weighted formulaic averages per API Chapter 21.1

(1993). Liquid meter averages are flow-weighted

averages per API Chapter 21.2 (2000).

The default history in the FB2200 can store the

following standard periodic logs for 60 variables. With

the flexible history design, the number of variables and

the time duration for different periodic logs can be

adjusted to meet the application requirement.

Automated Checksum Verification (ACV)

As an extended auditing feature, the flow computer

provides an option to perform online integrity checks

by generating firmware and configuration checksums.

The checksum is a 32-bit CRC number which is

routinely calculated and compared against the last

verified checksum. If a newly calculated checksum

does not match with the last verified checksum, the

system generates a checksum error and the flow

computer goes into an unverified state.

The flow computer supports extensive alarming

capability to enhance operational efficiency and

improve the audit trail. Alarms are pre-allocated to

meter runs and stations for standard values such as

pressure, temperature, differential pressure, or

frequency as well as meter run and station flow rates.

In addition to these standard alarms, the FB2200

provides a number of user alarms that you can assign

to other database parameters simply by “filling in the

blanks” in user alarm templates in the FBxConnect

configuration tool. Storage is provided for the most

recent 1000 alarms in the alarm log.

Alarms and Events

The flow computer supports extensive alarming

capability to enhance operational efficiency and

improve the audit trail. Alarms are pre-allocated to

meter runs and stations for standard values such as

pressure, temperature, differential pressure, or

frequency as well as meter run and station flow rates.

In addition to these standard alarms, the FB2200

provides a number of user alarms that you can assign

to other database parameters simply by “filling in the

blanks” in user alarm templates in the FBxConnect

configuration tool. Storage is provided for the most

recent 1000 alarms in the alarm log.

The event log stores the significant events during

operation and can be configured to either store all

events in a single log of 2000 events or the user can

select to store the metrology/legal events in a separate

log from the operational events. With the latter option

the event log capacity is 1000 metrology events and

1000 operation events.

variable’s value is questionable. The fallback options

can be one of the following:

▪ Use last good value

▪ Use a fixed fallback value

Firmware

The base firmware in the FB2200 flow computer comes
