4. POS Basics
Components of Overall System
There are two major components of a typical POS control system. The first component is the
POS application software that runs on personal computers running the Windows operating
system. The second component is the hardware connected to the POS control system. This
hardware may consist of Neundorfer equipment including MVC voltage controls, MicroRap rapper
controls, along with PLC equipment for hopper evacuation, soot blowing, and flue gas conditioning
systems.
Specific sub-component information for the Neundorfer MVC voltage controls, and MicroRap
rapper controls can be found in their respective manuals.
POS Hardware Components
The Neundorfer controls are linked together via an RS-485 multidrop network. The RS-485
interface is built into the rapper controls and voltage controls. On POS computers, the interface
may be an internal card or the output from the computer may be RS-232, which is then converted
to RS-485 by an external converter. For specific details implementing this network refer drawings
supplied with the system. Each device within a family of devices requires a unique address
number on the multi drop network. The voltage control addresses are set on the voltage control
front panel and range from 1 to 255. Each rapper control also requires a unique address number
from 1 through 32, and is set via the hand held programmer supplied with the control. The POS
computer is the master of this network, meaning it is the only device that can initiate a message.
The voltage controls and rapper controls can only send messages after specifically addressed by
POS using their control type and unit number. When the POS computer initiates communication
with a control, POS will wait for one of two events to occur before sending another message. The
first event is a valid response from the control and the second is a communication error. A
communication error will occur if the addressed control does not respond within the allotted time
or the message received is invalid.
For MVC4 voltage controls the data link between the POS computer and the voltage controls
should be a fiber optic link. The fiber optic link is converted to RS-485 at the voltage controls.
The fiber optic link is required to prevent ground loops between the grounded RS-485 cable’s
shield at the PC and the grounded voltage control cabinets.
Many POS software modules require external signals provided by other plant systems. These
inputs can be hardware wired electrical signals such as a 4-20mA input or digital communications
such as OPC or Modbus protocols. How these signals are brought into POS is very plant
dependant and therefore built custom for your installation. There will be hardware drawings
provided for and additional equipment provided for the interface of electrical signals.

POS Software Components
Data Logging
POS can be configured to log the following information to disk files:
• Voltage control operating parameters including primary and secondary voltages, power level,
control status (communication error, running, tripped, etc.), spark rate, operating mode and IE
ratio.
• Precipitator data including average and total voltage control operating parameters, opacity
signal, load signal and power optimization information.
• Rapper actuations.
• Auxiliary analog and/or digital inputs.
• SO3 Optimization actions.
• Soot blower actuations.
Actual data logged in your system will vary depending on which modules were purchased and how
the system is configured.
Status Monitoring
POS monitors the status of individual rapper controls, voltage controls and each rapper in the
system. In the overview screens, each item is color coded for quick identification of its status.
The overview screen is also factory customized to reflect the actual layout of the units it is
controlling. You can also view the voltage control’s operating parameters via the remote face
panel view, bar graphs and trend graphs. The remote face panel view of the voltage control also
allows the user to view the control limits or set points. POS also displays the program number
that is currently running in the rapper controls.
The 3D graph represents a plan view of the precipitator. This graph shows how the overall
precipitator is operating by displaying the selected parameter of each voltage control as a 3D bar.
This screen is useful for locating problem fields in a precipitator and verifying control setup
parameters.
POS also can display the status information of soot blowers, hopper evacuation systems, and flue
gas conditioning systems.

Remote Control and Programming
POS can also be used for remote control and programming functions. The functions can be
password protected to allow only authorized users access to them. POS has the ability to start,
stop and reset the voltage controls. Also, all the functionality available to the users at the control’s
face panel is also available in POS via the control’s remote view.
Users can also remotely program the MicroRap via the Rapper Control Programming Module
(RCPM). This module allows users to create and save an unlimited number of programs on the
computers hard disk drive for later transfer into any of the six valid user programs of the
MicroRap. Users also have the ability to remotely change which program number the rapper
control is executing, reset failed rappers and reset rapper control alarms.
POS also can provide control capability for soot blowers, hopper evacuation systems, and flue gas
conditioning systems.
Optimization (optional)
Performance optimization is probably the most powerful feature of POS. With this feature POS
automatically adjusts the voltage control’s operating limits based on one of two sets of
parameters. The first set is stack opacity and load. With opacity and load optimization, POS
continually adjusts the control’s secondary current limit by a user set percentage of full power.
The number of steps and timing of the steps are all user configurable. POS will lower the total
power of the precipitator until one of three things happen. The first being POS reaching the end of
the optimization program, the second is the opacity limit (user set) is reached which will either
abort optimization altogether or cause optimization to take one step back in the program. The
third item that can cause optimization to abort is a large change in the boiler load.
Performance optimization can also be configured to be based on stack opacity and precipitator
power. This operates similar to opacity and load except precipitator power levels are used instead
of boiler load levels. This type of optimization is most commonly used in cement plants.
MicroRap optimization allows the POS to automatically switch between the six stored MicroRap
programs based on a set of conditions configured by the user.
In SO3 optimization POS will adjust the PPM of SO3 to improve precipitator performance. POS
will then monitor the performance of the precipitator and when conditions warrant, it will begin
tuning the PPM to improve precipitator operation. This system requires an interface to the SO3
controls.

External Interface Options
We can supply POS with many types of external interfaces. The first is the analog and digital
input/output interface (see hardware components above). This interface is where most POS
installations receive the opacity and boiler load signals. Other analog and digital signals can be
read by POS, displayed on screen, contain alarm set points and logged to disk. POS can also
output total precipitator power to an analog 4 to 20 ma signal.
Another type of external interface is the Distributed Control System (DCS) interface. POS has the
ability to communicate to DCS systems via an Allen-Bradley data highway, Allen-Bradley DF1,
ModBus RTU, ModBus + and GE Series 9030 TCP/IP. These protocols are available from
Neundorfer to customers who have purchased DCS interfaces.
POS can also communicate on a wide range of PLC networks. Contact Neundorfer with your
specific requirements.
POS will also interface to SO3 injection systems, soot blower control systems and hopper
evacuation controls. All of these POS modules will interface to one or more PLC’s used to control
the related equipment. POS will provide status displays, control functions and in some cases
optimize system performance. All of these interfaces are used with the precipitator information
gather by POS to provide trouble shooting assistance, graphing capabilities, system alarming and
fault indication.

6. Overview of POS
POS Main Display
The POS main display is the screen that first appears when starting up your POS. There will be a
page for each precipitator contain in your systems. Some larger precipitators will require more
than one screen to display all the information. This display shows the status of voltage controls,
rapper control, individual rappers and the opacity, load and secondary kilowatts of this precipitator.
Note that the kilowatts are for the entire precipitator, not just the controls displayed on the single
page.
The rapper status is color coded. The codes are as follows:
Green : Ready to rap
Red: Has rapped
Magenta: Rapper failed – shorted
Yellow: Rapper Failed – Open
White: Communication Error between POS and the rapper control
This information is also available in the pop up as described in the next paragraph. The shape of
the rappers typically denotes the types of rapper being displayed. Circle rappers represent plate
rappers, square rappers represent wire rappers and diamonds represent other types that could
include sonic horns, inlet and outlet baffle rappers or motors type rappers.
All screen items are active, meaning you can right or left click on each item to access appropriate
functions for each device. Hovering the mouse over the TR set, rapper, precipitator and the
rapper control icons will activate a pop up for that device. The pop up will display at a minimum
the device ID in the system and some additional information. The rapper icons will display its

MVC Icons
On the Plan View window, each individual MVC is
represented by an icon. The icons have two different
drawing methods, the POS 7 style or the POS 6 style.
The user can toggle between the two icon display types
by right clicking on the TR set icon and selecting the POS
7 icon style enable line on the menu that appears. The
POS 7 style icon has live bar graph displays of current
operating data. The bar graphs are switched to text
displays when the TR set is off, trip or not communicating.
The POS 6 style icons resemble the plan view of a TR
set. The POS 6 icons are drawn with either one or both
bushings active and in a position according to your
individual precipitator’s actual layout. If the rotation is not
correct the user can change it by right clicking on the TR
set and selecting Properties on the menu that appears.
Select the Display tab once in the TR set properties and
adjust the rotation as desired. The color of the POS 6
style icons represent it’s current state and is set up as
follows:
Green: Stopped
Red: Running
Yellow: Tripped
White: Communication Error
POS 7 Style

POS 6 style
icons
MVC Control Menu
POS determines whether the icon is a single or dual
bushing TR set from the MVC configuration and adjusts
the icon display appropriately. For a POS 6 style icon, if
the secondary voltage of a bushing is below 1000 V then
that bushing will be colored in the “Off” state.
Pressing the T/R icon will display the MVC control menu.
The MVC name will appear in the window header. This
window contains buttons for each POS feature used in
monitoring or controlling a TR set. These features are
discussed in the sections below.
9. MVC Start Stop Control
The MVC controls can be started, stopped and reset from the control menu on an individual basis
by pressing the appropriate button. The voltage controls and POS has interlocking set up so that
if a control is stopped it must then be restarted from the same location, meaning if POS stops it
then POS must start it or if stopped locally then it must be started locally. This is to prevent
inadvertent start up of the control from another source if someone has shut it down to work within
the cabinet. Controls can be started and stopped as an entire precipitator through the precipitator
menu.

The Start button begins the data capture and transfer from the voltage control to the POS
computer. After pressing the Start the user can change the scope setup and begin another trace
by pressing the start button again. This action aborts the running data capture and begins a new
one. The line of text at the bottom of the trace contains a status message and the setup
information for the displayed scope trace.
The Select MVC dropdown list contains a list of all the voltage controls on the precipitator. The
control selected on this list is the control that will generate the oscilloscope traces.
The Trace Type drop down list lets the user select what type of data the user wants to display.
High Speed Data displays traces like those captured with a traditional oscilloscope. The signals
that can be graphed include Primary Current, Primary Voltage, Secondary Current,
Secondary KVa, Secondary KVb, and Conduction Angle. The Primary Averages trace type is
similar to a trend graph or a graph of face panel data except at a much higher data capture speed.
The signals that can be graphed include Primary Current, Primary Voltage, Secondary
Current, and Conduction Angle. The KvMin/Max plots a graph of the secondary voltage
minimum and maximum values of each half cycle of the line. The signals that can be graphed
include Secondary Current, Secondary Kva min, Secondary KVb max, and Conduction
Angle.
The Trigger dropdown list is where the user selects which event the control will begin its data
capture. The list includes Primary Current Limit, Primary Over Voltage Limit, Secondary
Current Limit, KV Limit, Conduction Angle Limit and Spark. The trace generation is event
driven and the user must select a trigger event that actually occurs in the MVC for the data
capture to begin and be transferred to POS.
The Sweep Speed drop down list is where the user selects the rate at which the data will be
gathered. This list will vary depending on the Trace Type selected.
Pressing the Store button saves the scope data to the CSV directory as a CSV file. The Retrieve
button brings that data back into POS for display. You can load the raw scope CSV data into a
spreadsheet application, the file is typically stored in the c:\vts\pos7\csv directory.
The Print button is used to send the graph image to any configured printer in the operating

Scattergram
The scattergram function is accessible through the precipitator menu. The scattergram is a
graph that shows how factors relate to each other on an XY plane. This is visual, not statistical,
and is used when it is necessary to compare two factors that are related.
Scattergram Window
The Scattergram plot can graph the following precipitator parameters:
• Load
• Opacity
• primary average volts
• primary total amps
• primary total kilowatts
• secondary total amps
• secondary average Kva
• secondary average KVb
• secondary total KW
• secondary average angle
• secondary average sparks
These parameters may be selected for either the X-axis or the Y-axis via drop down lists.
The data is retrieved from Log files and can span any historical range. Select Start and or End

between the operation of any two rappers in different fields in the same AG group. Use the drop
down list to set the AG Interleave time delay from 0.5 Sec to 53 Sec or to turn AG Interleave off.
The Field Repeat Time sets the time between the start of a field rapping and when that field will
start rapping again. Selecting the Minimum or Average will determine how the repeat time
interval is applied. If the repeat time is set to be average, the controller will attempt to catch up if it
falls behind in the rapping sequence by using the time set in the Minimum drop down list instead
of the time set in the Nominal drop down list. If the repeat time is set to be minimum, the control
will not attempt to make up time if it happens to fall behind in the rapping sequence. AntiCoincidence considerations can cause rapping to fall behind schedule.
The Minimum sets the minimum time between rappers when the Repeat Time is set to Average.

A prioritized set of six different logic conditions use Opacity, Load, Precipitator Power, or Time of
day to determine what program will run. When a condition becomes true the associated program will
be started and when that condition goes false optimization will continue to run that program until
another condition becomes true.

Pressing the Configure button opens a window to change configuration settings for the selected
MicroRap. Pressing the Edit button allows the user to edit the conditions. When in Edit mode,
pressing the Accept button saves the changes made. When in Edit mode, pressing the Cancel
button does not save any changes that were made, and all conditions will return to the way they were
before the Edit button was pressed.
Conditions
Each logic condition can trigger on any
combination of Load, Opacity, and Precipitator
Power signals. Alternately, the condition can be
set to trigger a program change depending on the
Time of day. A condition can be based either on
the analog signal parameters OR on the time of
day but not both together.
Setting a condition based on Time of day:
1. Select the Time of day checkbox.
2. Click on the time parameter to edit and
use the up and down arrows to edit that
value. This is completed for the Start
Time and End Time.
3. Use the up and down arrows to select
the program in the Start MicroRap
Example Condition
program # box.
If optimization is active when the Start Time is reached the condition will become true and the
selected program will begin. When the End Time is reached the condition will become false. If
another condition is true it will then switch to that program for that condition.
Setting a condition based on analog values:
1. Click the checkbox to select each parameter that will be used.
2. Enter a value in the given field.
3. If more than one parameter is selected use the Logical radio button to select And or Or.
Selecting And will require all selected parameters to be true for the condition to become
true. Selecting Or will require only one of the selected parameters to be true for the
condition to become true.
4. Use the up and down arrows to select a program in the Start MicroRap program # box.
If optimization is on when the parameters become true, the condition will become true and the
selected program will begin. If the parameters become false, the condition will become false.
The conditions are taken into consideration in priority order with Condition 1 having the highest
priority and Condition 6 having the lowest priority. If more than one condition is true, optimization
will switch to the program associated with the highest priority condition.

Power Off Rapping Over Data Link (optional)
Pressing the Power Off Rapping button on the MicroRap and TR set menus opens the Data Link
POR window. Data Link POR (Power Off Rapping) is a method of implementing power off rapping
through POS without having to hardwire the rapper controls POR output to the voltage controls
POR input.
Data Link POR Window
Power off rapping is a process used to reduce the power of individual TR Sets for a small amount
of time while executing a specialized rapping program. This is useful to periodically remove
excess particulate from the collecting plates in a precipitator without the electrical force of the TR
set holding it on the plate. Data Link POR allows the user to configure any number of
independent POR programs that can be scheduled to run at set time intervals while reducing the
power to a TR Set.
Functionality
The Data Link POR window displays configured POR programs and a schedule of POR
programs over a seven-day period for the selected rapper controller.
Data Link POR is a protected function and users will have to log in before starting and stopping
POR, changing configuration settings, or editing POR programs.

Trending Window Functions
The trending screens can be accessed through the precipitator and voltage control menus by clicking on
the trend item. The trend screen provides the user a method to easily view historical data in a graphical
format within the POS application. Accessing the trend screen via the TR set menu loads default pens
for that particular TR set. The default pens for a TR set are spark rate, primary amps, primary volts,
secondary milliamps, and secondary kilovolts. Accessing the trend function via the precipitator menu
loads the default precipitator pens, which are opacity, load, secondary power and total secondary
current.
If you select the trend option on another device while an existing trend window is active you will be asked
whether you want to add the pens to the existing graph. If you answer yes then the default pens for that
device will be added to the group of pens already being displayed on the existing graph. If you answer
no then a new graph will be opened with the default pen group.
Along the bottom of the display are two tabs, PlotView and GridView. Plot view displays the data

Performance Optimization (optional)
Pressing the Performance Optimization button in the TR set or precipitator menu will open the
Performance Optimization window. Optimization control is used to change power levels of
selected T/R sets in relation to changes in opacity and load levels, or opacity and precipitator
power levels. The program will reduce the power levels of the precipitator while monitoring
opacity levels to remain in compliance with user configurable opacity limits and will reset the
opacity base line to insure optimum opacity is achieved at all load or power levels.
Optimization Window
Performance optimization is password protected and users will need to log in before being able to
start or stop optimization.
Before running optimization you need to first create an optimization program and set the abort,
step back and timing parameters. A basic optimization program contains a series of steps taken
at specific time intervals (step time). Each step of the optimization program adjusts the voltage
control’s secondary current limit to a certain percentage of the controls full-scale limit. A step can
adjust any number of voltage controls on the precipitator. Limits are set on the opacity and load
or precipitator power levels that will cause optimization to abort to 100% power and start the
process over or cause optimization to step back one step in the program before proceeding
further. These limits and others are defined in the configuration portion of the manual.
Auto Optimization suspension function provides an auxiliary input to optimization that will reset
voltage controls to full power when the signal is present. POS will remember the program step it
was executing when the signal was applied. When the signal is removed, POS will step through

The optimization can run based on process load or precipitator power. Almost all plants run it
based on process load. The plants that run optimization based on precipitator power typically
select this option because they must maintain a specific power level in the precipitator to burn
waste fuel. This option is selectable based on the radio buttons in the upper left portion of the
screen.
The Max Load Change field sets the percentage change in load since the start of optimization
that will cause optimization to abort and restart the program from the beginning. This parameter
is checked continuously and will abort at any time while optimization is running. This parameter is
only used when optimization is based on process load.
The Max Step Load Change field sets the percentage change in load since the start of the

the full-scale power. This parameter is only checked at the end of a step and is only used when
optimization is based on precipitator power.
When the precipitator power levels fall below the number entered in the Minimum Power (Abort)
field, the optimization program will abort back to full power. This number is a percentage of the
full-scale power. This parameter is checked continuously and will abort at any time while
optimization is running and is only used when optimization is based on precipitator power.
If the opacity level exceeds the number entered in the Max Opacity field, optimization will abort
and all controls will return to full power. This parameter is continuously monitored and
optimization will abort at any time during the program.
The Abort Delay Time sets the time delay for optimization abort commands. When a limit is
exceeded, optimization will wait this time period, if the limit is still out of range after the time frame,
then optimization will abort. This is useful to prevent optimization from aborting during brief
opacity excursions, such as those caused by rapping.
If the precipitator opacity levels change by the number of percentage points entered in the Max
Step Opacity Change field during a single step, then optimization program will step back 1 step.
This parameter is only checked at the end of a step.
If the precipitator opacity levels change by the number of percentage points entered in the Max
Total Opacity Change field since the start of optimization, then optimization program will step
back 1 step. This parameter is only checked at the end of a step.
The Step Time field sets the length of time for each optimization program step. The values listed
on this drop list are even multiples of the data log interval of POS.
The Accelerated Step Time field sets a multiplier that affects the step time. This new step time
is used after optimization has been suspended. This step time will be used until optimization
returns to the program step it was running before suspension or until optimization has to step
back in the program a configurable number of times. This number defaults to three, but it can be
configured in the config.ini file.
The KW-HR Cost is where the user enters the cost per kilowatt hour in dollars. This value is

Start Up / Shut Down Module (optional)
Pressing the Start Up / Shut Down button on the precipitator menu will open the Start Up
Shut Down Program window. The Start Up Shut Down module is used to set TR set
operating levels based on analog and/or digital inputs to POS. A start up program will take TR
sets from the ‘Off’ state to full power. A shut down program takes the TR sets from normal
operating levels to the ‘Off’ state. The programs manipulate TR set operating levels by
adjusting secondary voltage or SCR conduction angle.
Controlling Inputs:
Users can select analog and digital inputs to be used as the controlling parameters. Users have
the option to use one or both types of inputs. The analog input selects which program step is
active. The digital inputs can be used as an enable, abort and end signal. Digital inputs, if used,
have priority over analog values.
Program:
The program will be a series of steps with one or more voltage controls set to a specific operating
level on a step. The module advances through the steps based on the values of the analog
inputs. If no conditions for any step are true then the module will maintain its current program
step until the next condition becomes true. When the program reaches the final step or all
controls are set to full power then the start up module will go to the ‘off’ state. When the program
reaches the final step or all controls are set to off then the shut down module will go to the ‘off’
state.
Minimize Sparking / Minimize Opacity
Each step will have the option of minimizing sparks or minimizing opacity. Spark minimization will
be handled by each MVC. When an MVC detects a spark it will adjust the secondary voltage
operating level to avoid further sparks until the next program step is executed.
Note: Minimize sparking mode will not eliminate 100% of the sparks. When a spark occurs, the
voltage control will attempt to prevent another spark from occurring.
To minimize opacity, POS will increase the voltage control operating levels by a user selectable
percentage at a user selectable rate any time opacity is above a specific percentage. When
opacity is below that percentage, the power levels remain steady. POS can not minimize opacity
if the control is trying to minimize sparks. If POS has increased the power levels of the voltage
controls to minimize opacity it will maintain those power levels when it advances to the next step if
the new step is also set to minimize opacity and the new power level set points are greater than
the prior set points but lower than the actual power levels. For example, step 1 sets the controls
to 30% and the step is in minimize opacity mode. Because opacity had risen POS increased the
controls to 36% power. Conditions go true for step number 2. Step number 2 is in minimize
opacity mode and is configured to advance the controls to 35% power. Since both steps are in
minimize opacity mode and step 2 was to raise power levels then POS will compare the actual set
point to the new set point. POS will then maintain the actual 36% set point since it is greater than
the new 35% set point.
Interaction with other modules:
When the start up / shut down module is running POS will not allow performance optimization, VI
curves or SO3 optimization programs to run. If those modules are running when the start up /
shut down mode is started, POS displays a message window that informs the user that these
modules will be stopped. This window will give the users the option to continue start up / shut
down or cancel. If the user tries to start those modules while in start up / shut down mode, POS
will display a window informing the user that they can not run while in start up / shut down mode.

POS Data Logging
POS collects data from many different sources. One type of data log file contains all the operating
data for each individual Voltage Control. There is a separate file created for each control on each
day. The filenames begin with the control name and a dash (-) character, followed by the year, a
two-digit month code and then a two-digit day code. For example, the data in the file
A5-20020417.DAT would be for voltage control A5 on April 17,2002. Another important data log
contains all the precipitator data including the analog load and opacity signals along with
optimization parameters and average electrical readings from the precipitator. There is a
separate file created each day for each precipitator on the system. The filenames begin with the
precipitator name and a dash (-) character, followed by the year, a two-digit month code and then
a two-digit day code. For example, the data in the file PRECIPB1-20020417.DAT would be for
precipitator B on April 17, 2002.
Data is also logged for each SmartSense, MicroRap Rapper Controller, soot blower, and flue gas
conditioning unit connected to the POS system. Like the voltage controls and precipitator log
files, a file is created every for each module attached to POS beginning with the unit name and a
dash (-) character, followed by the year, a two digit month and then a two digit day code.
All of the data logs also has a matching “*.LOG” file. This file contains the time and date
information the POS uses internally to get historical data.
Data File Locations and Maintenance
Since there is one file generated each day for each voltage control, precipitator, and any other
module on the system, regular maintenance is required to prevent the possibility of filling up the
computers hard disk drive. There will be a different directory for each month of data that stores
the *.DAT files. The files are stored in the C:\VTS\POS7\LOG\year-month# directory. If you
require extended historical data, we recommend you back these files up using the POS Back-Up
Utility. The files can then be transferred to a removable media such as a tape drive or CD
Burner.
Viewing Data
Data that has been logged by POS can be displayed in two different ways.
1) Live and historical data for precipitators (and voltage controls in the current precipitator)
can be viewed using the Precipitator Log.
2) Data can be used to generate custom reports that can be saved, printed, displayed onscreen or even emailed using the Report Generator.

SO3 Optimization
SO3 Optimization Window
The SO3 Optimization function in POS automatically adjusts the SO3 feed rate for lowest possible
opacity. SO3 Optimization then monitors precipitator performance to maintain optimum
conditioning. SO3 Optimization will re-tune itself when process conditions change or precipitator
performance degrades causing opacity or precipitator power to drift out of their established bands.
SO3 Optimization requires an interface to the SO3 control PLC.
SO3 Optimization can be configured to operate with four unique configuration settings. The
selection of which setting is active can be based on the boiler load, time of day or an external
signal of the user’s choice. The setup of each configuration setting is completed in the
Configuration Tab as described below.
All uses of opacity and power within this module are rolling averages over the “wait time” time
frame. Voltage control power readings are not added to the rolling average when its power is
reduced for power off rapping.
Performance optimization is not permitted to run while SO3 optimization is tuning the feed rate. If
performance optimization is running, it will abort back to step zero (100% power) and remain there
until the SO3 optimization module concludes the tuning process. When performance optimization
is re-enabled, it will start the program at the first step and proceed through the program at its
normal rate. The controls selected in the SO3 optimization module for power monitoring will not

(rolling avg.). Each log entry will also contain text describing the action it has performed. The log
interval will be the same as the “Wait Time” setting.
When a user turns off SO3 optimization, POS will restore the SO3 PPM to the PLC’s default feed
rate.

result in PPM range of 10 – 20 PPM)
Wait Time – Sets the amount of time the program waits after each PPM adjustment to check the
effect it had on the average opacity.
Opacity Dead Band – Is the range in which opacity is permitted to fluctuate after SO3
optimization is complete. If opacity drifts outside this band then SO3 optimization will begin to
adjust the PPM based on precipitator power readings to get the opacity back within the band.
Power Dead Band – Is the range in which precipitator power is permitted to fluctuate after SO3
optimization is complete. If precipitator power drifts outside this band then SO3 optimization will

Required PLC IO
SO3 Optimization requires a number of digital and analog IO points to operate. In POS the points
are accessed by right clicking on the SO3 Optimization icon and selecting properties on the menu
that appears. The settings described below are found on the indicated tabs of SO3 Optimization
properties window. These points will be configured at Neundorfer when the software is created or
by the Neundorfer field engineer during start up.
POS requires the following PLC IO points for proper operation:
The settings below are found on the PPM tab:
Operating PPM inut: Analog address used by POS to read actual operating PPM from the PLC.
Operating PPM output: Analog address used by POS to write a new operating PPM to the PLC.
This input to the PLC may be the same register as Operating PPM Input. The PLC will need to
divide this value by 10.
Default PPM Output: Analog address used by POS to write a new default PPM to the PLC after
optimized. This input to the PLC may be the same register as Operating PPM. The PLC will need
to divide this value by 10.
The Settings below are found on each Condition tab:
Initial PPM Input: This setting is an analog address used by POS to read the initial PPM from the
PLC. This is the PPM that optimization will utilize when it begins the tuning process. This input is
only used in POS if the use AI checkbox is checked on the PPM Adjustment window for each
configuration.
Condition 1 Input: This is a configuration item that can be used to control which condition is true
via a signal from outside of POS.
PPM Deadband Output: An analog output that provides a location for POS to write the PPM
deadband to the PLC. This output is not required by POS but is provided if users utilize this value
in their PLC logic.
The settings below are found on the Misc tab:
SO3 Enable: Digital address used by PLC to initiate SO3 optimization routine in POS. This bit
must be true for POS to optimize SO3 PPM.
SO3 Optimization on: Digital address set by POS when the optimization routine is turned on.
Even though optimization is turned on, POS will not optimize until the SO3 enable bit is set.
POS Toggle Bit: Digital output toggled by POS and monitored by PLC to confirm
communications. This bit will toggle once every 45 seconds.
PLC Functionality
The PLC SO3 control remains the primary controller for the Sulfur injection process. The typical
structure for this control is adjusting the Sulfur feed rate to maintain a specific SO3 PPM at a
given boiler load. The feed rate adjustment is typically completed through the utilization of a
lookup table.
The SO3 Optimization module in POS assumes that the standard feed rate can be optimized for
better opacity and/or lower raw material (Sulfur) usage. The SO3 optimization module adjusts the

PPM to achieve the best possible opacity and then attempts to lower the PPM while maintaining
the best opacity level.
For SO3 optimization to function correctly the SO3 injection system must be in a steady state
condition. Typically this is at a steady boiler load and injecting SO3 into the flue gas for at least 30
minutes. The PLC will control when POS can begin optimization by setting SO3 Enable bit to 1.
When system operation is no longer in a steady state condition (change in load or no longer
injecting SO3) the PLC should revoke the optimization privilege in POS by setting the SO3 Enable
to 0. When the PLC exits optimization mode it should begin using the default PPM to set the SO3
feed rate.

Appendix A – Communication Troubleshooting
General Items to check
1) Make sure unit numbers in controls match unit numbers in POS.
2) Make sure termination resistor settings are set properly in all controls and RS-232/RS-485
converters, RS-485 repeaters and fiber optic devices.
3) For MVC 3 voltage controls. Make sure jumpers are in the active position for controls that you
wish to have connected to the data link.
4) Make sure RS-232/RS-485 converters, RS-485 repeaters and fiber optic devices are turned
on and switch settings are set correctly.
5) Make sure the serial cable is plugged into correct serial (COM) port of computer.
6) Make sure all cables are plugged into the proper ports of RS-232/RS-485 converters, RS-485
repeaters and fiber optic devices.
7) Check to see if any lights on the RS-232/RS-485 converters, RS-485 repeaters and fiber optic
devices are flashing. If none are flashing, the problem is in the cabling to the PC or the PC
configuration.
8) Has it ever communicated? If not check the polarity of the communication cables. Also
check polarity of cables if people have recently been working in the cabinets.
9) Check POS configuration. Are all voltage controls set to same type? The MicroRap should
be set to 19200 baud for MVC3 data link or 4800 baud for MVC2 data link.
10) For MVC 3 voltage controls. The data link LED should be lit when controls are in remote
mode and flash when the control is actually sending a message. If the light is not lit in remote
mode then change the logic board.

does not contain any communication circuitry.
Treat each control as 1 MVC not communicating.
Problem is with the data link cabling or a fault in a single control.
• Check the cable continuity between the last good and first bad
control.
• Check cable polarity between the last good and first bad
control.
• Verify termination resistor settings.
• Remove the first bad and last good control from the data link
(see figure below for MVC 3). If the remaining controls begin
communicating then the problem is with one of those two
controls. If the other controls do not communicate then refer to
the section below on determining which control is bad.
• Check unit numbers of all controls.
• Check termination resistor settings.
Disable communications to other controls that are not
communicating.
Increase communication time out setting in the c:\vts\oem\config.ini
file.
The MicroRap does not support the data log message. Upgrade
MicroRap firmware to version 3.5 or later, or set MicroRap data log

How to determine which control has failed
when a portion of a data link is not communicating
Equipment required:
Oscilloscope
System Prints
Replacement logic board
1) Check all other trouble shooting options in this document.
2) Refer to sample oscilloscope traces as a reference for good communication signals.
3) When checking communication signals, place the oscilloscope ground clip on the DATA –
line. The scope probe should be placed on the DATA + line. Refer to the prints shipped with
your POS system to find these points on your controls.
4) The control communication data link is a daisy chain configuration. Select the center point of
this chain.
5) Attach the scope probes as described above.
6) Break the communication data link at this point. For MVC 3 controls refer to the jumper
settings described in this document. For MVC 4 controls turn power of to the control or plug
two communication connectors together.
7) Check the oscilloscope display. If the communication is good then the problem is in the last
half of the data link. If the communication is bad then the problem is in the front half of the
data link.
8) Reconnect the data link.
9) Go to the center of the data link section that was determined as bad.
10) Attach scope probes as described above.
11) Break the communication data link at this point. For MVC 3 controls refer to the jumper
settings described in this document. For MVC 4 controls turn power of to the control or plug
two communication connectors together.
12) Determine which data link section the bad control is located. Repeat steps 8 through 12 until
the problem could be narrowed down to 1 control.
13) Replace the logic board or remove the problem control from the data link. For MVC 3 controls
refer to the jumper settings described in this document. For MVC 4 controls turn power of to
the control or plug two communication connectors together.

Appendix B – Internet Server Configuration
Configuring the POS/VTS internet server
In order to enable a VTS Internet Server to allow VTS Internet Clients access to the POS
application, there are three basic configuration operations that must be performed:
•
•
•
Valid user accounts must be established within the POS application for those users
wishing to access them remotely via a VTS Internet Client. These user accounts must
have the "Internet Client" privilege granted to them.
A "realm" must be established on the VTS Internet Server that contains the POS
application.
The VTS Internet Server must be assigned a port.
The section that follows provides brief instructions on configuring a VTS Internet Server to
accept VTS Internet Client connections.
Configure a VTS Internet Server to Accept VTS Internet Client Connections
The instructions provided below are a summarized account of how to configure a VTS Internet
Server to accept VTS Internet Client Connections.
Create a User Account for Each User in POS
In the POS application you wish remote users to have access, you must create a user
account and password. Instructions on doing so are provided below.
1. Run POS on the VTS Internet Server.
2. Logon to the application with a user account that has at least the Manager privilege (that
enables you to create new accounts and modify existing accounts).
3. Create a user account for each of your intended remote clients. Ensure that each user
account has at least the Internet Client privilege granted to it.
Now that you've established user accounts for each intended remote client in POS, you will
need to establish a realm that includes the POS application. Instructions are provided below.
