Action Blocks – The FB2200 supports up to 30 action

blocks. Action blocks are used in conjunction with

effect blocks to monitor a configured condition and to

perform an action (effect) when the logic is “true.” An

action block consists of a user defined Boolean logic

statement with two variables. These variables can

either be live parameter values or constants.

Multiple action blocks can be chained together to

create more complex logic. Each action block includes

multiple bypasses, which can temporarily halt the

action to be taken for maintenance and safety.

Effects – The FB2200 supports up to ten effects. Effects

cause an action to occur when the result of one or

more action blocks is active (“true”). Multiple action

blocks can cause the same effect, such as shutting a

valve or enabling an alert beacon.

You configure an effect by defining an output

parameter and the values to write to that parameter

when the effect is either active or inactive. You can also

configure an active effect to be self-clearing or to

require a manual reset.

Control

The FB2200 optionally supports control functions

including PID control, basic programming through

action blocks, effects, and math blocks.

PID Control – The FB2200 supports up to three

Proportional, Integral, and Derivative (PID) control

loops. Each PID instance supports a primary and an

override loop. Each loop has its own user-defined

input, output, and override capability.

Typically, a PID control maintains a process variable at

set point. If you configure a PID override control, the

primary loop is normally in control of the control

device but the override loop can take over control of

the process if required. A typical example would be

primary flow control with a pressure override.

FBxNet™

FBxNet is a secure, easily configurable, peer-to-peer

communication network for exchanging data between

Emerson FB3000 RTUs and FB1200 and FB2200 flow

computers over an Ethernet connection. FBxNet

supports subscriber and publisher devices, where

publishers provide data to their subscribers. The

FB3000 RTUs and FB1200 and FB2200 flow computers

can be publishers; only an FB3000 can be a subscriber.

For more information, refer to product data sheet

FBxNet (part D301905X012).

Mounting Options

The FB2200 supports direct mounting to a manifold on

the pipeline, simple wall mounting, or mounting on a

two-inch pipe with the stainless steel pipe mounting kit.

Expansion I/O

In addition to the base I/O provided, the FB2200 I/O

capability can be increased by adding two options. The

expansion below provides 2500 Vdc isolation from the CPU.

▪ 8-channel isolated expansion board, providing 4

channels that are individually software-selectable

as either analog inputs or analog outputs and 4

channels that are individually selectable as discrete

inputs, discrete outputs, or pulse inputs.

▪ 6-channel isolated expansion board, providing 2

channels that are individually software-selectable

as either analog inputs or analog outputs and 4

channels that are individually selectable as discrete

inputs, discrete outputs, or pulse inputs.

Note: The 8-channel expansion board option must be

added first. The 6-channel expansion board can

only be used in units that already have the 8

channel board included.

▪ Two optional relays allow for additional loads up to

30 Vdc at 6A. 24 Vdc is required to energize the

relays or an expansion I/O option must be selected,

which enables 24 Vdc loop.

Note: This option is available only with Class 1 Div 2 approval.

Inputs and Outputs

Base I/O

In addition to the integral pressure sensor, the FB2200

includes the following I/O points in the base unit:

▪ Two analog channels – individually software

selectable analog inputs (AI) or analog outputs (AO)

▪ Two discrete channels – individually software

selectable discrete inputs (DI), discrete outputs

(DO), or pulse inputs (PI)

▪ One RTD/PRT (2-, 3-, or 4-wire)

Analog Inputs (AI) are individually software

configurable for either 4 to 20mA or 1 to 5 Vdc

operation.

To keep measurement uncertainty at a minimum when

external transmitters are being used, both the AI and

AO channels have industry-leading measurement

accuracy with an excellent performance over a wide

ambient temperature range.

Each Discrete Input (DI) channel can also be software

configured to function as a latched DI.

The Discrete Output (DO) channels are solid-state,

normally open switches rated at 500 mA, enough to

directly drive most samplers. Each DO channel can be

software configured as a latched, toggled, momentary,

timed duration output (TDO), or scaled pulse output.

The PI channels are most commonly used to interface

with turbine meters, Coriolis meters, ultrasonic meters,

and Positive Displacement (PD) meters. The high

speed input supports signal up to 10.5 KHz.

Temperature Input (RTD/PRT)

With industry-leading measurement accuracy, the

temperature measurement of the FB2200 ensures that

you minimize your measurement uncertainty in all

operating conditions. The input accepts 2-, 3-, or 4-wire

connections reducing any field wiring induced errors

and also supports sensor curve matching using the

optional Callendar-Van Dusen constants to define the

unique characteristics of the RTD/PRT to further

improve process temperature measurement uncertainty.

The FB2200 flow computer’s superior static pressure,

DP, and temperature measurement performance and

stability ensures you meet standards and regulations

so you can avoid fines, penalties, leaseholder disputes,

and lost revenue.

Integral Pressure Sensor Options

The flow computer can be supplied with one of three

sensor options to suit your metering needs:

▪ Integral Multivariable Sensor (MVS) measuring

both static pressure and differential pressure (DP)

▪ Integral inline static pressure sensor

▪ NO integral pressure sensor – external transmitters

are used

The NO integral sensor option is typically used at

locations where regulations classify the location of the

pressure measurement sensor as either C1 D1 or

ATEX/IEC Exd Zone 1. In this instance, the FB2200

without an integral sensor can be mounted in the C1

D2 / Zone 2 area and be connected via a serial port to 1

or 2 remote 4088B MVT transmitters.

If the FB2200 has an integral sensor, it can

communicate with one remote 4088B transmitter for

dual meter run applications.

Enabled by superior sensor technology and

engineered for optimal flow performance, the integral

pressure sensor on the flow computer delivers

unparalleled accuracy, over a wide range of operating

conditions, and industry leading stability to ensure you

meet standards and regulations.

Pressure sensors on the flow computer can measure

DPs of up to 1000” of water / 2500 mBar and static

pressures up to 4000 psi / 275 bar in either gauge or

absolute with accuracies up to 0.05% of reading.

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
