1.1.1 Solutions

The configuration, control and communication data in the RTU are saved in a hierarchy of
folders called a solution (with a file type of .zsl). A solution may also include up to eight
applications. You use FBxConnect to modify, upload, or download solutions.

Note

It is a good practice to always save backups of your solutions.

1.1.2 Applications

Applications add extra functionality to the FB3000. An application consists of a project
created in FBxDesigner and can include multiple displays built with FBxVue. Each
application runs in its own task and can be independently added, removed, started, or
stopped.

1.2 Demo Overview

In this demo you use an FB3000 to simulate and control a two-phase separator, including
the measurement of the outlet gas and liquid streams.

The gas is measured with a DP meter using API 21.1-compliant AGA 3 flow calculations
while the liquid is measured with a linear turbine meter. The liquid level of the separator is
measured by a guided wave radar device and monitored by high- and low-level switches. A
control valve on top of the separator regulates the gas flow to control pressure and a
control valve on the bottom of the separator regulates the liquid to control the liquid level.

During normal operation, a PID controls the gas control valve to maintain the pressure at a
setpoint. The liquid level control valve opens when the high-level switch activates and
closes when the low-level switch activates.

You use FBxConnect to build the FB3000’s standard configuration, which includes IO
configuration, meter set-up, and controls for the simulation of the separator;
to build a program that opens and closes the liquid control valve; and FBxVue to build a
user display that includes a graphic of the separator liquid level, a gauge for the pressure,
and the status of the control valves and meters.

1.2.1 Demo Folders

3.3 Math Blocks

You use math blocks to define calculations. Each math block has up to four inputs and
three calculations, which can each be saved to writable OPIs. The system performs math
block calculations once a second.

To configure math blocks, select the Configure tab and click the Math Blocks option:

The Math Blocks screen displays:

Note the drop-down menu option in the upper left-hand corner of the screen. Use it to
select the math block to define.

For this demo, we’ll define two math blocks: one to simulate the liquid level and another
to simulate the pressure:

3.3.1 Simulating Liquid Level

You use the first math block to simulate the liquid level in the separator.

Enter Level Simulation as the tag for Math Block 1.

Notice that each control feature has an Enable Switch to turn it on/off. Select the Enable
option for this math block:

FBxConnect 31

Emerson FB3000 Separator Configuration Guide

D301884X012
October 2019

To simulate the liquid level, you need to know the current level, how much the level is

rising due to the inlet stream (we’ll pick an arbitrary number), and how much the level is
falling due to the outlet control valve.

To define the inputs:

For Input A:

 Enter Current Level as the Description.

 Open the Point Picker.
 Select AI_ > Liquid Level (Instance 2-1) > Selected Value.

The Selected Value of a point is equal to the live value when the operation mode is set to
Live and is equal to the override value when the operation mode is set to Override.

For Input B:

 Enter Inlet Stream as the Description.
 Enter 0.5 as the Value (do not open the Point Picker).

For Input C:

 Enter Control Valve as the Description.
 Open the Point Picker.
 Select No Filter at the top of the Point Picker screen.

32 FBxConnect

Emerson FB3000 Separator Configuration Guide

 Select DO_ > Lvl Cntrl Valve (Instance 2-1) > Auto Value

D301884X012

October 2019

The inputs should now look like this:

With the inputs defined, we can now define the calculations.

The new, calculated level is the current level (Input A) plus the rise due to liquid entering
through the inlet stream (Input B, arbitrarily set to 0.5 inches per second)
due to liquid leaving through the control valve (Input C ). Since the control valve is 0 when
closed and 1 when open, we’ll just use that value so that it causes a fall of 1 inch per
second when open.

Note

This is not an accurate simulation that considers real-world variables like changes in
pressure. It is a simplified calculation intended

For the X calculation, enter A+B–C:

only for demonstration purposes.

minus the fall

Let’s also calculate a new pulse input for the liquid meter so that it is zero when the valve is
closed and 100 when the valve is open. For the Y calculation, Enter:

FBxConnect 33

100*C

Emerson FB3000 Separator Configuration Guide

D301884X012

Then we need to store the results:

For Result X:

 Enter New Level as the Description.

 Open the Point Picker.
 Select AI_ > Liquid Level (Instance 2-1) > Override Value.

For Result Y:

 Enter Liquid Meter as the Description.
 Open the Point Picker.
 Select PI_ > Liquid Meter (Instance 2-6) > Override Frequency.

Click Save. At this point, the Syntax Check fields for both calculations should change to
green and display Valid:

If they do not, there is a syntax error in the calculation that you need to correct.

Notice that that New Level value should start to drop from 30 because the Control Valve is
open.

All the liquid will drain out of the separator until we add controls to close the valve.

3.3.2 Simulating Pressure

You use the second math block to simulate the pressure in the separator, which is used to
module the gas control valve.

Select Math Blk_2 (Math Block 2) from the drop-down menu at the upper right of the
screen:

Enter Pressure Simulation as the Tag and enable the math block.

We simulate the pressure in the same way we simulated the liquid level. We need to know
the current pressure, how much the pressure increases due to an inlet stream, and how
much the pressure decreases due to the control valve.

FBxConnect 35

Emerson FB3000 Separator Configuration Guide

D301884X012
October 2019

Define the inputs:

For Input A:

 Enter Current Pressure as the Description.
 Open the Point Picker.
 Select AI_ > Pressure (Instance 2-5) > Selected Value.

For Input B:

 Enter Inlet Stream as the Description.
 Enter 0.5 as the Value.

For Input C:

 Enter Control Valve as the Description.
 Open the Point Picker.
 Select AO_ > Gas Cntrl Valve (Instance 2-1) > Auto Value.

The inputs should look like this:

For this calculation we need to do something different from the control valve outlet, since
this is an analog output calculation that goes from 0 to 100% instead of from 0 to 1.
Additionally, gas compresses and responds to pressure changes much more than liquid, so
we need to account for that.

We approximate the outlet as the Control Valve % Open (Input C) multiplied by the
Current Pressure (Input A) and then divided by 1000 so that it’s about the same magnitude
as the inlet stream.

Note

This an even less-accurate simulation that the liquid simulation, since gas compression and
flow calculations are much more complex. Again, this is a simplified calculation intended
only for demonstration purposes.

So, for the X Calculation, enter A+B–C*A/1000:

Since we are calculating the pressure of the separator, we also need to update our 4088
static pressure that we’re using for our meters. Since the 4088 Pressure is in Absolute
pressure psi(a) and our input pressure is in Gauge Pressure psi(g), we need to add one
atmosphere of pressure (about 14.7 psi).

For the Y Calculation, enter X + 14.7:

36 FBxConnect

Emerson FB3000 Separator Configuration Guide

Now we store the results:

For Result X:

 Enter New Pressure as the Description.
 Open the Point Picker.
 Select AI_ > Pressure (Instance 2-5) > Override Value.

For Result Y:

 Enter 4088 Pressure as the Description.
 Open the Point Picker.
 Select Press_ > 4088B-1 Press (Instance 1-1) > Override Value.

D301884X012

October 2019

Click Save. Check that the values for the Syntax Checks are valid.

The pressure should now start to increase because the control valve is currently closed (0%
open).

3.4 Action Blocks & Effects

Action blocks enable you to define simple logic operations. Each action bock checks if
some condition is true/valid and if it is, triggers some action or effect(s). An individual
action block can trigger different types of actions or multiple effects. You can also chain
action blocks logically.

Click Action Blocks on the Configure tab.

The Action Blocks screen displays:

Note that the drop-down menu in the upper left-hand side of the screen displays all
defined action blocks:

In this part of the demo we are going to use action blocks (and an effect) to simulate the DI
high-level and low-levels switches.

Select Action Blk_2 (Action Block 2) in the drop-down menu at the top right of the screen.

Enter Low Level Switch as the tag for Action Block 2 and enable the action block.

Define the logic for the action block:

 Enter Liquid Level as the description for Variable 1.
 Open the Point Picker for Variable 1.
 Select AI_ > Liquid Level (Instance 2-1) > Selected Value.
 Select Less Than as the Operator.

Click Save. Note that the value for Effect Status is now ACTIVE and it shows that the Low
Level Switch Action Block (2) triggered the effect. Also notice the Output Value (DI 2-3)
changes to 1.0

3.5 PID Loops

A PID loop is a common control loop feedback mechanism. Typically, a process variable is
compared to a setpoint and the error is used to calculate an output. Tuning parameters are
used to create the desired behavior, but there is a trade-off between responding quickly to
error and overshooting or causing oscillation.

Emerson FB3000 Separator Configuration Guide

D301884X012

FBxDesigner Basics

 An FBxDesigner project consists of one or more Program Organization Units (POUS)

and task(s).

 POUs can be programs, functions, or function blocks.
 POUs are composed of worksheets that contain comments, variables, and program

code.

 Programs can use other functions and function blocks in their program code.
 Program code is written in the IEC61131 languages (FDB, ST, LD, SFC, and IL).
 A POU does not do anything until it is told to run by a task.
 A task defines when to run program instances.
 After making a project, you must compile it and create a boot project.
 Once created, the boot project can be downloaded to the RTU

In this portion of the demo we are going to use FBxDesigner to create a simple project that
opens and closes the liquid level control valve based on whether the high- and low-level
switches are active.

Periodically Check the Project for Errors

When you are creating a project (and as you proceed through this guide), it is a good
practice to frequently check the project for errors as you add new sections of code and
make changes. Click
for errors.

Build > Make on the top menu to compile the entire project and check

The Message Window on the bottom of the FBxDesigner screen displays any errors and
warnings that you must correct.

Errors are typically syntax mistakes, improper Data Type usage, or missing variables.
Warnings usually indicate that you have created something that is not being used.

IF High = 1

…

D301884X012

October 2019

Let’s start programming. We want this function block to take in the statuses of the High­level and Low-level Switches and
close the valve (send 0) if the Low Level switch is active. If neither switch is active, the
function block should send no value so that the Valve status does not change.

Let’s start with an IF statement to check if the High_Level switch is active.

Enter:

open the valve (Send 1) if the High Level switch is active or

THEN

Valve := 1;

This checks if the High-Level Switch Input is equal to 1, and if it is, sends 1 to the Valve
output. If it is

Enter:

not equal to 1, we then need to check if the Low-Level Switch is active.

ELSIF Low = 1

FBxDesigner 61

THEN

Valve := 0;

END_IF;

Note that the IF statement must end with an END_IF statement.

Although we are done typing the code, we have not yet defined our variables. Essentially,
the program does not yet know what the words High, Low, and Valve mean.

Right-click the word High and click Variable to open the Variable Properties window.

Select INT as the Data Type and select VAR_INPUT as the Usage. Click OK.

Repeat the process for the variables Low and Valve but indicate Valve as VAR_OUTPUT.

Finally, before leaving this worksheet, click Build > Compile Worksheet from the top menu.

This performs a check for any syntax errors or undefined variables in the code. Any errors
or warnings then appear in the Message Window at the bottom of the FBxDesigner screen:

5.2 Building a Display with FBxVue

In this section, we build a display to show:

 A graphic of the liquid level in the separator tank
 Pressure Gauge & Pressure Setpoint

 Valve Statuses and Meter Flow Rates

This is what the final display should look like:

First, give the display a title. With Canvas selected in the Display Outline, enter Separator
Display as the Title in the Properties window.
