xii Video Recorder – User Manual

1.1 Video Recorder Overview

The Video Recorder (Figure 1-1) is part of the family of multi-point, multi-function video products. The
instrument offers display versatility, flexible data storage, up to 8 control loops, each one can run its own
profile, and advanced math functions. This integration of several functions eliminates the need for
multiple devices and reduces installation costs.

The instrument features a high resolution LCD display which is capable of displaying up to 16 different
colors simultaneously. The front door opens to allow access to a 100MB ZIP disk drive. A mini DIN
connector can be used on the front door for connecting a PC keyboard or barcode reader for easy
labeling of parameters. Barcode reader also stores Event Records to disk.

Sixteen panel keys control all functions of the instrument, including configuration.
The instrument will accept thermocouple, RTD, pyrometer, milliamp, millivolt and volt inputs. Up to eight

analog outputs are available for retransmission or control. Data can be directed to various display
formats, stored on floppy disk, or read from an optional serial communications link. Analog and discrete
data can be displayed in trend or tabular format. Viewed data can be either “live” (real time inputs) or
historical (retrieved from disk).

Flexible modular design and several options make this instrument adaptable to nearly any industrial
application.

2.4 Wiring the video recorder

2.4.1 Recommendations

CAUTION

• All wiring must be in accordance with local electrical codes and should be carried out by authorized and

experienced personnel.

• The ground terminal must be connected before any other wiring (and disconnected last).

• A switch in the main supply is mandatory near the equipment.

• If an external fuse is used to protect the electrical circuit to the video recorder, the fuse should match the

video recorder fuse rating (fuse type) as well as for the fuseholder.

• Sensor wiring should be run as far as possible from power wiring. (motors, contactors, alarms, etc.)

• To reduce stray pick-up, we recommend the use of a twisted pair sensor wiring.

• EMI effects can be further reduced by the use of shielded cable sensor wiring. The shield must be

connected to the ground terminal.

Failure to comply with these instructions may result in product damage.

2.5.7.5 Rear connection

The video recorder has built in circuits to reduce the effects of most electrical noise. We recommend
that you review the following guidelines, to minimize the noise effects.

1. Separate the communication leadwires from the line voltage, the alarm output, contactors, motors etc...

2. For a communication distance, over 1.5 meters, use a separate metal tray, or metal conduit.

3. Use wiring cable composed of twisted pair wirings, with a shield for RS485 and RS422. Use a shielded
cable for RS232.

4. Connect the shield wire to the ground, at one end only, preferably at the video recorder. Use for example
a wiring cable type: Belden 9271 twinax, or equivalent.

5. We recommend to install a 120 ohms resistor between TXA and TXB, on the last video recorder on
communication link.

6. The maximum capabilities are:

Type of communication Distances max. # of Unit

RS232 15 meters / 50 feet 1

RS422 1000 meters / 3280 feet 15

RS485 1200 meters / 4000 feet 31

Section 4.9 Program Analog Outputs

Section 4 How To Program Function Blocks and Features

3.3 Modes of Operation

The instrument has three modes of operation: Program, Online, and Maintenance. Each mode has its
own menus. Most menu items provide access to sub-level menus. The SET MODE item switches the
instrument from one mode to another. Your instrument may have reduced menus if options are not
present.

Program mode

Program Mode is an off-line mode for programming (configuring) the instrument. In this mode, all inputs
and outputs are frozen. If any of the five relays are assigned as DAT outputs the recorder will stop
pulsing them when it is placed into Program Mode. The outputs will remain frozen in their present state,
either On or Off.

Online Mode

Online Mode enables full use of the instrument with its inputs, outputs and internal programming. In this
mode, it is fully interactive with all externally connected elements.

Maintenance Mode

Maintenance Mode is an off-line mode for maintaining proper and complete functioning of the instrument.
Functions include calibration, off-line diagnostic testing, and various setups for operation. In
Maintenance Mode, all inputs and outputs are frozen. If any of the five relays are assigned as DAT
outputs the recorder will stop pulsing them when it is placed into Maintenance Mode. The outputs will
remain frozen in their present state, either On or Off.

To develop a feel for navigating between modes, power up the instrument and perform the sequence of
steps that follows.

Upon powering up the instrument for the very first time, the logo display will initially appear. Press the
Menu button several times until the ON LINE, PROGRAM, or MAINTENANCE mode MAIN MENU is
displayed. Refer to Figure 3-2. Note: Menus are shown with all possible options; your menu may not
have all options.

Once you have established which MAIN MENU you are on, use the Up Arrow and Down Arrow buttons
to verify each MAIN MENU choice as indicated in Figure 3-2.

Use the Up Arrow and Down Arrow buttons to find and highlight the menu’s SET MODE prompt.

When the SET MODE prompt is highlighted, press the Enter button.

Use the Up Arrow or Down Arrow buttons to switch the instrument to one of the other two instrument
modes and press the Enter button.

Programming and Operating Concepts

Once within the mode selected in Step 5, scroll through the mode’s MAIN MENU using the Up Arrow and
Down Arrow buttons. Verify each menu choice as indicated in Figure 3-2.

Repeat Steps 3 through 6 for the last of the three mode selections possible.

Having completed the preceding exercise, changing the instrument’s mode should now be a simple task.
Furthermore, a fundamental understanding of how the Menu, Up Arrow, Down Arrow, and Enter buttons
work should now be at your fingertips.

Now use the Menu, Up Arrow, Down Arrow, and Enter buttons to verify the ON LINE, PROGRAM, and
MAINTENANCE mode sub-level menus detailed in Figure 3-3, Figure 3-4 and Figure 3-5. The sub-level
menus shown represent only the first sub-level below each mode’s MAIN MENU. There are several sub­level menus, not indicated here, that run further below each first sub-level. Note that once inside of a
sub-level menu, regardless of how “deep” the level is, a press of the Menu button will return you to the
next highest menu level. In case you get lost within a mode’s sub-level menu, keep pressing the Menu
button until the ON LINE, PROGRAM, or MAINTENANCE mode MAIN MENU appears on screen.

Be advised that Figure 3-2 through Figure 3-5 comprise a basic “road map” for navigating the menus
within the programmer’s three modes. Sections 4 through 8 of this manual will provide detailed
descriptions of each menu choice and complete guides through all the sub-level menus that run below
the levels indicated in these Figures.

3.9 Definition of Function Blocks

Definition

A function block is a unit of software that performs a set of operations on its input parameters and
function block parameters and produces output parameters. These output parameters can be

programmed as inputs to other function blocks, whose output parameters can be programmed as inputs
to other function blocks, and so on. By programming all desired function blocks' input parameters and
function block parameters, you configure the instrument to measure and control your process.

Types of function blocks

Each function block performs a set of operations which fulfills a unique purpose. For example, the
Analog Input function blocks processes the analog input data, the alarm function block processes
alarms, and so on.

Table 3-3 describes each function block.

Some function blocks—namely, Analog Input, Analog Output, Discrete Input, and Discrete Output—
interface with the hardware; that is, they are the link between the instrument and the input or output
hardware. The Analog Input and Discrete Input function blocks convert the incoming process data (like
the process variable or any discrete on/off signals from a switch) into information usable by the
instrument. This incoming information is processed according to the entire function block configuration in
the instrument, and it is ultimately passed on to the output function blocks. The Analog Output and
Discrete Output function blocks convert this output information into a voltage or current which is fed to
the corresponding output hardware (like a current output or relay).

Other function blocks are not directly “seen” by the hardware; they are purely software. They can be
thought of as the middle of the process described in the previous paragraph. For example, a Standard
Splitter Calculated Value can split a control loop’s output into 2 values: one for heating and one for
cooling. These 2 values can be passed on to the Analog Output function block which ultimately controls
the amount of output current or voltage.

Programming and Operating Concepts

Flow of information

The “flow” of information— from the input hardware to the input function blocks to the function block
configuration to the output function blocks to the output hardware—can be likened to a river flowing from
upstream to downstream. In some cases, like with a control loop’s feedback, this analogy is not true
because the information is flowing in a circle, but it is a helpful way to view how function blocks are
generally interconnected. For example, the Analog Input function block is typically upstream of the
Control Loop function, which is typically upstream of the Analog Output function block. Of course, if two
function blocks are not directly or indirectly connected, there is no flow between the two. Just remember
that every function block has input, does a set of operations, and produces an output. When several
function blocks are linked together, there is a flow of information.

* Depends on options ordered.

Why use function blocks?

Function blocks give you configuration flexibility. For instance, the instrument does not have a dedicated
relay that is activated during an alarm; instead, you can program any of several Alarm function blocks to
control any relay. Also, there is not a specific input for your process variable; any of several Analog Input
function blocks can be programmed to be your process variable. In general, function blocks let you
connect the output parameter of any function block to the input parameter of any function block.

3.10 Components of function blocks

The three components of a function block are:

Input parameter(s)

Function block parameter(s)

Output parameter(s).

Input parameter

A function block's input parameter can be configured to be OFF, a number, or it can receive its data from
outside the block from another block's output codes. These output codes are shown in
Table 3-4. That is, an input parameter is any menu item that can be programmed as (connected to) one
of these output codes. These output codes are grouped under the menu choice PARM. When you are
programming a function block and one of your choices is PARM, you know you are programming an
input parameter. See Figure 3-7.

For example, suppose you are programming an alarm function block. One of the alarm’s menu items is
INPUT, which specifies which point will be monitored for an alarm condition. One of the choices for the
INPUT is PARM, which lets you connect the INPUT to one of the output codes in Table 3-4. Therefore,
the INPUT is an input parameter because it receives its data from another function block.

Some function blocks can have multiple input parameters. For example, an Alarm function block has an
INPUT and a SETPOINT, both of which can be connected to other function blocks.

Discrete Input function blocks have no input parameters; that is, they have no inputs that can be
connected to another block’s output codes.

Video Recorder – User Manual 51

Programming and Operating Concepts

Function block parameter

A function block parameter’s data is contained within the block. When you are programming a function
block and are not given a choice of PARM, you are programming a function block parameter. Typical
choices when programming a function block parameter are NONE, OFF, any numerical value, or a list of
options for the parameter, but not PARM. See Figure 3-7.

For example, to program an Alarm function block’s ALARM ACTION, you select from a list of choices:
NONE, LOW, HIGH, DEV, LRATE, HRATE.

Other function block parameters are an Analog Input’s RANGE LOW and RANGE HIGH, where you
specify the voltage range or temperature range.

Output code

An output code is the result of the function block's operations on the input parameters and function block
parameters. It is designated by one of the two-character output codes shown in Table 3-4. An output
code can be programmed to be the input to one or several other function blocks. See Figure 3-7.

Output codes are either discrete (can be on or off) or analog (numerical value). For example, DI1 OS is
the output status of Discrete Input #1: on or off. AI1 OV is the output value of Analog Input #1: a voltage
or temperature. Therefore, a discrete input parameter must be programmed with only a discrete output
code, and an analog input parameter must be programmed with only an analog output code.

ATTENTION

The function block SYSTEM PARAMETER, abbreviated SY, does not have input parameters or function block
parameters like the other function blocks; SY produces output codes only. These output codes, shown in Table
3-4, are mostly values or states that indicate the status of system-wide parameters. For example, if any Alarm
function block’s output status is ON, the SY function block’s AG (alarm global) output code is also ON.

Another example is the SY F1 output code, which produces a quick ON-to-OFF discrete signal when the F1
key is pressed. This SY F1 can be used as a trigger to another action. For example, to allow an operator to

start the Profile or reset the Totalizer by pressing the F1 key, you can program a Setpoint Profile’s Start
parameter or a Totalizer’s Reset parameter with SY F1.

3.11 How to program input parameters

A function block has two types of programmable parameters: input parameters and function block
parameters. When in a function block’s Program menu, if a menu item has choices OFF, a number, or
PARM, then the menu item is an input parameter to that function block. That is, if you choose PARM
you can connect the input parameter to another function block’s output code.

How to connect an input parameter to another function block

One way to program an input parameter is to connect it to an output parameter from another function
block. We will show you this procedure using a specific function block’s input parameter, but the
keystrokes used in the procedure will apply when you are making any input parameter connection.

Assume we want to make the connections shown in Figure 3-8. We want Analog Output#1, a current
output, to get its input from Control Loop#2’s output value. Therefore, we must program Analog
Output#1’s Input Source parameter with the output code that represents Control Loop#2’s output value.
The following procedure shows how.

Table 3-5 Output Code Connection Procedure

Step Action

1 In the Program Analog Output menu, select ANALOG OUTPUT#1.

2 Consult the Program Analog Output section of this manual to learn about the menu item you wish to

change, namely, INPUT SOURCE.

3 Press Down Arrow button to move the cursor to the menu choice INPUT SOURCE.

4 Press Enter to move the cursor to the right side of the display where the choices for INPUT SOURCE

are.

5 Press Up Arrow until PARM is displayed. If you press too many times and a number is displayed,

continue pressing Up Arrow until PARM is displayed again. If you press Down Arrow while the
number is displayed, the instrument assumes you want to enter a number, not a parameter. If you
pressed Down Arrow, you must press Menu, then press Enter, then Up Arrow until PARM is
displayed.

6 Press Enter to select PARM, which gives you choices for output codes to connect to. Figure 3-9

shows the format for all output codes.

7 Press Up Arrow or Down Arrow until LP is displayed. From Table 3-4, we know LP is the designator

for the Control Loop function block type.

8 Press Enter to select LP.

9 Press Up Arrow or Down Arrow until 2, the Control Loop number we want, is displayed.

10 Press Enter to select 2.

11 Press Up Arrow or Down Arrow until OV is displayed. From Table 3-4 we know OV is the output

code for the Control Loop’s output value.

12 Press Enter to select OV. The cursor moves to the left and the connection from LP2 OV to Analog

Output#1’s INPUT SOURCE has been made.

Figure 3-9 Function Block Connection Format

Before programming a function block’s input parameter with a CV’s (Calculated Value) output code, you
must program the CV first. Otherwise, the CV’s output parameter will not be available for programming.

The function block SY (System Parameter) operates internally and cannot be programmed. It
automatically produces outputs which reflect the status of alarms, data storage, diagnostics, and
reference junction temperature. These outputs can be used as inputs to function blocks.

How to program an input parameter with a number

Besides connecting an input parameter to another function block, you can program an input parameter
with a number. The instrument will accept -999,999 to 9,999,999.

Continuing with the previous example, assume we want Loop #2’s Setpoint #2 to be a number.
Therefore, we must program Loop #2’s Setpoint #2 parameter with a number, say 95. The following
procedure shows how.

Video Recorder – User Manual 56

Programming and Operating Concepts

Table 3-6 Example Number Selection Procedure Using Front Panel Buttons

Step Action

1 In the Program Control Loops menu, select LOOP #2.

2 Consult the Program Control Loops section of this manual to learn about the menu item you wish to

3 Press Down Arrow button to move the cursor to the menu choice SETPOINT #2.

4 Press Enter to move the cursor to the right side of the display where the choices for SETPOINT #2

are.

5 Press Up Arrow until NUMBER is displayed. Press Enter.

6 The rightmost digit will slowly flash on and off, indicating the cursor position.

Since we want to change the number to 95.00, press the Left Arrow until the ones digit flashes. The
Left Arrow moves the cursor to the left.

7 Press Up Arrow to change the 0 to a 5.

8 To change the tens digit, press Left Arrow to move the cursor one place to the left.

9 To change the 0 to a 9, press Up Arrow nine times.

10 At this point, 95.00 should be displayed with the 9 flashing. Since 95.00 is the value we want, press

Enter to select it. The cursor moves left to the SETPOINT #2 prompt and the value is selected.

ATTENTION

To enter a number with a connected keyboard, instead of steps 5-10 simply type in the number 95 and press
Enter.

How to program a discrete input parameter with a number

Table 3-6 shows how to connect Setpoint #2, an analog parameter, to a number. You can also connect a
discrete parameter to a number. A discrete parameter, such as an alarm’s input source, can be
connected to any discrete parameter type in Table 3-7, or it can be programmed with a 0 to signify the off
state or with a 1 to signify the on state. Enter a value of 1 or 0. For example, if you program an alarm’s
input source (Figure 3-7) with a value of 1, the alarm’s output (AL1 OS) will always be on.

To program a discrete parameter with a 1 or 0, perform the following procedure. The procedure uses
Alarm1’s Input source as the parameter being programmed.

Table 3-7 Example Programming Discrete Input Parameter with a Number

Step Action

1 In the Program Alarms menu, select ALARM #1.

2 Consult the Program Alarm section of this manual to learn about the menu item you wish to change,

namely, INPUT SOURCE.

3 Press Down Arrow to move the cursor to INPUT SOURCE.

4 Press ENTER to move the cursor to the right side of the display where the choices for INPUT

SOURCE are.

5 Press Up Arrow until 1 or 0 is displayed.

6 Press ENTER to select. The cursor moves to the left and the display indicates your choice of 1 or 0

has been made.

Video Recorder – User Manual 57

Programming and Operating Concepts

ATTENTION

Note the difference between programming a discrete parameter with OFF and programming it with a 0. “OFF”
means “not connected”; 0 means “off state”.

3.12 How to program function block parameters

The second type of programmable parameter is a function block parameter. A function block
parameter’s data is contained within a function block and cannot be connected to another function block.
When you are programming a function block and are not given a choice of PARM, you are programming
a function block parameter. Typical choices when programming a function block parameter are NONE,
OFF, any numerical value, or a list of options—but not PARM.

Programming procedure

Here is the procedure for programming a function block parameter. It is an example using a specific
function block parameter, but the keystrokes used will apply when you are programming any function
block parameter.

Continuing with the example from Figure 3-8, assume we want Analog Output#1 to default to its lowest
value if the input source, LP2 OV, fails. Therefore, we must program Analog Output#1’s failsafe
parameter with the appropriate selection. The following procedure shows how.

Table 3-8 Example Function Block Parameter Selection Procedure

Step Action

1 In the Program Analog Output menu, select ANALOG OUTPUT#1.

Consult the Program Analog Output section of this manual to learn about the menu item you wish to

change, namely, FAILSAFE.

3 Press the Down Arrow button to move the cursor down to FAILSAFE.

4 Press Enter to move the cursor to the right side of the display where the choices for FAILSAFE are.

5 Press Up Arrow or Down Arrow until DOWN is displayed.

6 Press Enter to select DOWN. The cursor moves to the left and DOWN is selected.

3.14 How to program common configurations

Being able to diagram a control configuration in terms of function blocks makes it easier to program and
configure your instrument for its intended process control application. This function block diagram you
create can be used as a “construction blue print” to program the instrument. Each block in the diagram
relates to a dedicated instrument programming menu in the instrument’s PROGRAM mode.

What follows are examples where common control configurations are presented along with their function
block diagrams. The first example is a simple control arrangement in great detail to help you understand
function block diagram basics, followed by more sophisticated examples. Once you understand how to
diagram function blocks, you will be able to draw a diagram for virtually any control strategy regardless of
complexity. Understanding the relationship between such diagrams and the instrument’s programming
menus is key to successfully mastering the instrument’s many capabilities and features.

Programming a Current Driven Heat Treat Element

An example of one of the most common and simple control strategies is in Figure 3-11 below.

Video Recorder – User Manual 60

1. Diagram the function blocks

To configure this application using the instrument, your task is to build up a simple current control loop.
Note that this control loop must monitor and control the temperature of the furnace zone to a local set
point of 500 ºF. Using a 4 to 20 mA signal applied to a gas valve actuator, the furnace zone’s
temperature will be controlled by regulating the flow of gas to the zone’s burner.
The instrument will measure temperature, in a range between 0 and 1000 ºF, by means of a Type J
thermocouple.

To support this application, a 4 to 20 mA control loop with a thermocouple process variable must be
configured. Three function blocks—one for specifying a thermocouple analog input, a second for a
standard PID control loop, and a third defining a 4 to 20 mA analog output—are needed to produce this
control strategy’s function block diagram.

Each function block should first be arranged as in Figure 3-12. Analog input and output function blocks
are represented by right-pointed triangles. Control loop function blocks are represented by right-pointed
parallelograms.

2. Label input parameters

Properly label each function block. First, assign to each function block a name that identifies it within the
hardware and feature capacities of the instrument being worked with. You may assign any of the analog
inputs, control loops, and analog outputs that your instrument has to the blocks comprising the function
block diagram drawn. For simplicity, AI1, LP1, and AO1 will be used in this example.
Refer to Figure 3-13. Note that AI5, LP2, and AO2 could just as easily have been used.

AI = ANALOG INPUT

LP = CONTROL LOOP

AO = ANALOG OUTPUT

Video Recorder – User Manual 61

Programming and Operating Concepts

3. Label output parameters

The second part in labeling each function block is to denote the blocks’ major input and output
parameters. Each of these parameters will correspond to actual menu settings that you program on the
instrument. As shown in Figure 3-13, the AI1 function block’s input parameter will be the actual Type J
thermocouple run from the furnace to the instrument’s AI1 input terminals. The AI1 block will process the
thermocouple’s millivolt signal to generate a temperature measurement. AI1’s output value, denoted
“AI1 OV”, will essentially be the furnace zone temperature. The LP1 function block is shown, for now,
with one input denoted by “PV”. Here, the control loop block will expect to find the data comprising its
process variable. The LP1 block’s single output is the loop’s main control output. Denoted “LP1 OV
(Loop 1’s Output Value)”, it will range between 0 and 100%. The value of LP1 OV at any given instant
will be determined by the control loop function block’s PID algorithm.

The last block in the diagram is the analog output function block, AO1. Drawn at this point with just a
single input and output, its primary purpose will be to generate a 4 to 20 mA signal that linearly
corresponds to whatever value is applied at its input. For example, if AO1’s input is defined as some
value that ranges from 0 to 100%, an input value of 0% will cause AO1 to generate a 4 mA signal at the
instrument’s AO1 output terminals. A 12 mA signal will be generated in response to an input of 50%,
while 20 mA will result when a 100% input value is applied. AO1’s input parameter is denoted “IN”, with
its output parameter labeled to identify it as the physical 4 to 20 mA signal detectable at the pair of
instrument rear terminals dedicated to AO1.

AI1

Figure 3-13 Labeling Each Function Block’s Name And Major Inputs And Outputs

4. Label function block parameters

Finally, label each block’s internal parameters. “Internal parameters” may also be referred to as “function
block parameters.” As in the case of input and output parameters, internal parameters associated with
each block correspond to actual menu settings you program in the instrument. While input and output
parameters constitute either data exchanged between function blocks or physical signals exchanged
between the instrument and the outside world, internal parameters are settings that uniquely define the
operation of the function block they are associated with. Use of a function block’s internal parameters is
for the most part limited to within the operations of the function block itself.

It is not always possible, or even practical, to draw every internal parameter that a function block has or
might need. Therefore, as a rule-of-thumb for starting out, you should first think of internal parameters
as simple labels that further define and clarify the internal operation of the function block. With this rule­of-thumb in mind, internal parameters become items that are hopefully intuitively obvious. At this point,
what may or may not be an “intuitively obvious” internal parameter will depend on your level of process
control expertise. For the function block diagram built up so far, internal parameters that can be
presumed from the control strategy of Figure 3-11 are indicated in Figure 3-14. Here, the AI1 function
block has been labeled to show that its “INPUT TYPE” will be a Type J thermocouple with a
measurement range between 0 (RANGE LOW) and 1000 ºF (RANGE HIGH).
The label “STANDARD” has been used to indicate the type of control loop LP1 will be, along with the
notation “SP = 500” to show that the loop’s set point will be 500 ºF. The loop tuning constants of GAIN,
RESET, and RATE have been initially indicated as 10, 1 repeat/minute, and 0 minutes, respectively. As
far as the AO1 function block is concerned, its input range has been defined between 0 (IN LOW LIMIT)
and 100 (IN HIGH LIMIT) in anticipation of using LP1’s output to drive the 4 to 20 mA signal it will
generate. Note how AO1’s output range has been defined through use of the notation “OUT LOW LIMIT
= 4” and “OUT HIGH LIMIT = 20.”

Note that the internal parameters that we have specified in the function block diagram built up so far are
based largely on what can be inferred from the elements of the control configuration depicted in
Figure 3-11. These internal parameters will relate directly to settings found in instrument programming
menus that exist for each particular function block. As your experience and familiarity with programming
the instrument increases, you will become more familiar with some of the less intuitive parameters and
you will include these in your diagrams.

5. Connect the blocks

The next step is to connect the function blocks in the diagram. Refer to Figure 3-15.
The interconnection lines drawn depict the flow of information between function blocks and represent
how the blocks work together to support the complete control strategy. As shown, the furnace zone
temperature measurement that AI1 generates will essentially be used as the process variable of the LP1
control loop. Based on the values of the loop’s tuning constants and on how far AI1 OV deviates from
the 500 ºF set point, the control loop function block’s PID algorithm will accordingly adjust LP1 OV to
whatever value will be necessary to maintain the process’ set point. LP1 OV, which ranges from 0 to
100 %, will in turn be applied to AO1’s input to drive the 4 to 20 mA control signal applied to the valve
actuator. By modulating the valve actuator’s position, this 4 to 20 mA signal will regulate the gas flow to
the furnace zone burner and thereby allow the instrument to control the heat levels measured in the
zone.

6. Draw the Feedback connection

To fully complete the function block diagram, one final and very important interconnection must be
drawn. In setting up control loops in this instrument, a feedback path must be specified between the loop
function block itself and the hardware element that externalizes the loop’s output to the real world. That
is, the control loop block needs confirmation from the analog output block connected to it that the percent
output levels it calls for have been correctly translated into accurate output signals. The feedback path
that provides LP1 with this confirmation is established by means of program settings depicted in
Figure 3-16.

Here, the function block diagram is drawn to include the key components of a typical loop feedback path.
The AO1 function block has been changed to feature a second output denoted “AO1 BC.” This output
has been connected to a feedback input at LP1 identified by the notation “FB.” The “AO1 BC” designator
stands for “Analog Output 1’s Back Calculation.” When the control loop is brought on-line, AO1 BC will
essentially represent the value of AO1’s 4 to 20 mA output at any particular instant. The term “Back
Calculation” is used to reinforce the idea that this information is being sent “upstream” against the flow of
all other information within the function block diagram.

This application requires a basic time proportioning control loop to monitor and control the pH of the
wastewater to a local set point of 7 pH units. That is, the loop will “neutralize” the wastewater so that it
can be safely released to the environment. The wastewater pH, which is assumed to be primarily acidic,
will be controlled by introducing a caustic reagent to the contents of the treatment vessel. This will be
done through use of a time proportioning relay signal that will pulse a pump connected to a caustic
reagent source.

This drawing is similar to the temperature control application. The analog input, control loop, and analog
output function blocks (AI1, LP1, and AO1) have been used similarly. The discrete output function block
was added, drawn as a circle at AO1’s apex and named “DO1.” Recall that any analog input, control
loop, analog output, or discrete output available may be used. Up to 36 discrete outputs (DO1 through
DO36) are potentially available depending on the instrument’s model number.

Video Recorder – User Manual 65

Programming and Operating Concepts

From Figure 3-18, the instrument’s AI1 function block will essentially process the 4 to 20 mA transmitter
signal to generate a pH measurement. This measurement will be “AI1 OV” which, in turn, will be applied
to LP1’s process variable input, “PV.” Before the 4 to 20 mA signal is applied to AI1, it will be converted
to a 1 to 5 VDC signal with a 250 Ω shunt resistor. AI1 will be configured to generate a pH measurement
in a range from 0 (RANGE LOW = 0) to 14 (RANGE HIGH = 14) in response to a voltage input between
1 (CKT LOW = 1) and 5 (CKT HIGH = 5) VDC. The PID algorithm of the control loop function block will
adjust the value assumed by LP1 OV between 0 and 100%. This 0 to 100% signal will be applied to
AO1, which will be configured as a DAT type analog output. The internal parameter of “IMPULSE TIME”
in AO1 is the DAT analog output’s cycle time or period. With a specified impulse time of 150 seconds
(an arbitrarily picked value), the DAT output will be ON for 75 seconds and OFF for 75 seconds when the
input from LP1 is set to 50%. The ON and OFF times will be determined completely by the % output
levels called for by LP1. Finally, to externalize the ON and OFF output states of AO1 to the outside
world, the DO1 output relay, represented by the DO1 function block, will be programmed for AO1’s
exclusive use. Hence, as AO1 switches between ON and OFF states in response to LP1 OV’s % output
levels, so too will the DO1 output relay to generate the pulses required to drive the caustic reagent
pump.

Split Output or Duplex Control

Split output or duplex control loops are typically used in heat/cool applications. Temperature is
controlled through simultaneous use of both heating and cooling elements. If the instrument was to
support a heat/cool control configuration, an example of the control scheme that might be dealt with is
illustrated in Figure 3-19.

be programmed. The temperature of the water will be measured by means of a three-wire 100 Ω
Platinum RTD. This process may be likened to manipulating hot and cold faucets regulate water

variable input (PV) of the LP1 control loop block. Note how LP1 has been defined as a split output
control loop using the notation “TYPE = SPLIT.” Unique to this control loop is the defined range of its
output value, LP1 OV. Where the standard control loops mentioned thus far have had outputs ranging
exclusively between 0 and 100%, the % values of the split output control loop vary between -100 and

100. 0% is considered the midpoint for this control loop’s output range. When brought on-line, a 0 to
100% output value will be generated by LP1 when hot water is needed to maintain the temperature at set
point. When the addition of cold water is necessary, the loop’s output will assume a value between 0
and -100%. Note that to externalize the control signals generated by LP1, two analog output blocks,
AO1 and AO2, will be used. AO1’s 4 to 20 mA signal will be tied to the hot water valve actuator, while
the actuator that adjusts the position of the cold water valve will receive its mA control signal from AO2.
To provide AO1 and AO2 with usable input driving signals, LP1’s output will be applied to a function
called a “standard splitter (STD SPLITTER).” Made from one of the instrument’s calculated value
function blocks (“CV’s”), the standard splitter will essentially be a mechanism that translates the %
values of the split output control loop into two distinct 0 to 100% signals. They will be applied to the
inputs of AO1 and AO2 and, as such, will drive and linearly correspond with AO1 and AO2’s 4 to 20 mA
outputs.

The two outputs on CV1 that will drive AO1 and AO2 are respectively labeled “CV1 A1” and “CV1 A2.”
CV1’s basic operation is described by a plot of these outputs versus LP1 OV. Shown in the lower left of
Figure 3-20, the plot demonstrates that CV1 will produce a 0 to 100% value at its CV1 A1 output when
LP1 calls for an output level between 0 and 100%. CV1 A2 will remain at 0%. When applied to AO1, the
CV1 A1 value will activate the 4 to 20 mA signal needed at the hot water valve actuator to make the
water temperature in the vessel rise. Similarly, when LP1 calls for an output level between 0 and -100%,
CV1 will produce a corresponding 0 to 100% value at CV1 A2. This time, CV1 A1 will remain at 0% and
the CV1 A2 value generated will induce the introduction of cold water into the vessel to cool its contents
down.

Note the function block diagram’s use of three back calculated feedback paths. Two such paths are
labeled AO1 BC and AO2 BC. They are connected to CV1 from the analog output function blocks at
inputs denoted “FB1” and “FB2.” CV1 BC, the third feedback path, runs from CV1 to the FB input of
LP1. All three feedback paths work together to acknowledge to LP1 that the appropriate output signals
have been generated in response to the % output levels the loop has called for.

Cascade Control

An example of a cascade control application is featured in Figure 3-21. Cascade control is typically used
when two process values must be simultaneously controlled, with one process value directly influencing
the behavior of the other. In this control strategy, each process value is supported by its own dedicated
control loop. The term “cascade” is used because it describes how this control approach literally
attaches both control loops together. This act of linking control loops allows for the regulation of both
process values using one and only one % output control signal.

Figure 3-21 Temperature Control Of An Oil Heated Chemical Reaction Chamber

InFigure 3-21, the temperature in a chemical reaction chamber is determined by the temperature of the
heated oil surrounding it. Heating the oil is done by an electric heating element driven by a 4 to 20 mA
controlled SCR and external power source. In this application the instrument controls the temperature of
the chemical reaction chamber through control of the heat emitted by the jacket tank oil. The instrument
must provide a single 4 to 20 mA control output to govern the voltage switched by the SCR and, hence,
the heat applied to the entire system. Temperature is monitored with thermocouples.

The function block diagram of the required instrument configuration is featured in Figure 3-22

Note that this diagram illustrates the classic cascade arrangement of two control loops that defines the
cascade control strategy. The first control loop, LP1, is designated as the primary cascade loop by the
notation “CAS_P.” The notation “CAS_S” indicates LP2’s designation as the secondary cascade loop.
Note how both control loops are joined together. In addition to the back-calculated feedback path set up
between the two (LP2 BC), LP1’s output is connected to an input on LP2 that at this time must be
introduced. Denoted as SP2, this input is LP2’s remote set point input.

Figure 3-22 Function Block Diagram Of The Cascade Control Strategy

Recall that based on the instrument’s model number, up to eight control loops (LP1 through LP8) are
potentially available for use within the instrument. All control loops in this product may be programmed
to operate using up to two user defined set point parameters, designated by SP1 and SP2. Should you
implement a control loop using one or both setpoints? That depends on what is necessary to meet the
requirements of the specific application being dealt with. When in the on line mode and viewing a control
loop’s dedicated on line display, the working set point of the live control loop can be switched between
SP1 or SP2 by simply pushing the “SP” key on the instrument’s front door. Note that while both set point
parameters may be programmed to have straight numeric values, only SP2 may be defined as a remote
set point. That is, SP2 may be set up so that its value is determined by the output value of another
function block, such as a setpoint profile. In the cascade control strategy demonstrated in Figure 3-22,
SP2’s remote set point functionality is exploited by the LP2 secondary cascade loop. When this control
configuration is made operational, LP2’s working set point, SP2, will have a value determined by LP1
OV.

In Figure 3-22, the process values of each loop are the output values of the AI1 and AI2 analog input
function blocks. AI1 will produce temperature measurements of the reaction chamber and provide them
to the process variable input of LP1, while measurements of the oil temperature in the jacket tank will be
furnished to LP2’s PV input by AI2. Because LP1 OV will provide LP2 with its operating set point, LP1’s
output range will be defined in engineering units of temperature instead of the usual 0 to 100%. LP2’s
output range is 0 to 100%, in anticipation of using it to drive the AO1 function block’s 4 to 20 mA signal.
Note that the range covered by LP1 OV will have to be consistent with the operating temperature range
of the oil. For example, if it is determined that the oil temperature will be manipulated between 75 and
500 ºF, the low and high limits assumed by LP1 OV (and, for that matter, SP2) will equal 75 and 500,
respectively. Finally, LP2 BC and AO1 BC are the two back-calculated feedback paths shown. As is
true for the operation of all back-calculated feedback paths, both LP2 BC and AO1 BC work together to
acknowledge the cascaded control loops that the appropriate actions have taken place in response to
both loops’ output values.

The method used to coordinate the tuning of the cascaded loops is particularly interesting. Using the
diagram of Figure 3-22, the first priority is to tune the secondary cascade loop of LP2. With LP1 kept in
manual mode, tuning may begin by first placing LP2 in manual mode and then manipulating LP1’s
output. This will allow the generation of an LP2 set point that will induce a process upset when the
secondary loop is placed back in automatic mode. Only after LP2 has been tuned can LP1 be tuned.
When tuning LP1, LP2 will be kept in automatic mode throughout the entire time LP1 is exercised. Since
the tuning of LP2 will have already been established, tuning LP1 may be approached by first mentally
“blocking out” the secondary control loop’s existence and visualizing LP1’s output as connected to a sort
of virtual analog output function block. In this light, tuning the overall cascade control configuration
becomes the considerably simpler matter of tuning a single control loop.

Set Point Profile Implementation

By definition, set point profiles are essentially user specified plots of process values against time. These
plots are characterized by “segments” which are a series of intervals of varying time lengths that divide
the plots into several segments. Within each segment, process values are typically drawn as straight
lines that ramp up or down or stay constant at predetermined levels. An example of a simple five­segment set point profile is shown in Figure 3-23. Set point profiles with up to 63 segments can be
specified using the instrument. Note that when a segment depicts the process value as sloping up or
down, it is referred to as a “ramp.” The term “soak” is used to describe a segment when the process
value is made to stay constant. In Figure 3-23, segments 1, 3, and 5 are ramps while segments 2 and 4
are soaks.

Figure 3-23 Example Set Point Profile

To force a process value to vary linearly with time at various rates within successive time intervals is the
job of a set point profiler, another class of function blocks available within the instrument. Be advised
that use of set point profilers is typically observed in thermal or heat treat applications. For example,
being able to vary temperature in accordance with a set point profile is vital in the tempering of metal or
ceramic parts.

Refer to the application of Figure 3-11 discussed at the beginning of this section. This application dealt
with controlling a furnace zone’s temperature by means of a 4 to 20 mA gas valve actuator. If the
furnace zone temperature were to be manipulated so that it followed the ramps and soaks of a set point
profile, the first step would be to implement the function block diagram established in Figure 3-16In
general, the control configuration that holds a process value to a local set point, must be programmed
and on line before allowing the process value to be characterized by a profile. With regard to the
application at hand, a set point profiler function block programmed with a user defined set point profile
may be brought into the configuration once the furnace zone’s basic temperature control loop is
operational. Note that the output of the profiler function block will essentially be the set point profile.

From the cascade control strategy’s explanation, recall that all control loop function blocks within the
instrument have a Setpoint #2 parameter that may be used as a remote set point input for connecting to
the profiler’s output.

LP1 in the function block diagram of Figure 3-16 will make use of SP2’s remote set point functionality so
that a set point profiler’s time varying set point may be applied to it. Refer to Figure 3-24.

Figure 3-24 basically depicts all the components of the Figure 3-16’s control configuration with a set
point profiler function block denoted by SP1. The profiler’s output (SP1 OV) is connected to the remote
set point input of LP1. Depending on the model number of the instrument, up to four set point profiler
function blocks (SP1 through SP4) may be included within the instrument’s feature capacities. Note that
while the profiler of SP1 was specified in Figure 3-24’s diagram, any of the profilers within the instrument
could have been used.

When a set point profile is executed, discrete inputs are typically used in conjunction with external
switches to control the set point profiler function block. For example, the set point profiler function block
can be programmed to start, hold, or reset based on discrete input statuses. See Figure 3-25.

Also typical in the execution of a set point profile is the generation of discrete events during each profile
step. Discrete events are simply status indicators that are programmed to assume either an ON or OFF
state during a step of a profile. As simple discrete status indicators, these events may, for example, be
used to initiate a logic control scheme on the process being controlled upon the occurrence of a
particular profile segment. In this product, note that up to 16 discrete events may be programmed per

3.15 Data Storage

This instrument supports either floppy 1,44 MB or 100 MB ZIP disks. Note that only DOS formatted
floppy disks may be used in the instrument’s disk drive and the unit’s front door must be closed for any
disk drive operations to take place. The floppy disks may be initialized in the instrument or on an IBM­PC with the initialize utility.

Read this overview thoroughly to understand the fundamentals behind the instrument’s data storage
capabilities.

Categories of Stored Data

There are four categories of disk storable data. Each category of data is stored in its own unique file.
The categories are:

Data Storage

Configuration Storage

Setpoint Program Storage

Calibration Storage

Data Stora ge Confi guration Ca l ibrationSetpoint Program

Process Data Diagnostic Data

Uni t Data
Ala rm s
Eve n ts

Figure 3-28 Categories of Stored Data

The first category of stored data, Data Storage, is comprised of two types of data: process data and
diagnostic data. When the instrument stores these data types it is essentially functioning as a recorder.

Process data is comprised of up to four files containing historical information on the process that the
instrument is monitoring and/or controlling, such as the temperature trend or a log of a furnace over time.
Process data also includes any alarm or discrete event information.

Diagnostic data is the result of the instrument’s execution of diagnostic routines during instrument start­up and maintenance procedures (such as calibration). Online operation is also monitored to detect both
process faults and internal electronic errors. If a diagnostic error occurs, a record of it can be stored to a
single diagnostic file.

The second category of stored data is configuration storage, which is a single file comprised of the
instrument’s programming and configuration. Configuration storage includes the programming of the
instrument’s analog input characteristics, the configuration of its control loops, or, perhaps, the
programming of any math or logic functions.

The third category of stored data is Setpoint Program storage, which is a single file –a setpoint program–
containing one to eight setpoint profiles, depending on the instrument. Recall that set point profiles are
user specified plots of process values against time that are divided into ramp and soak segments of
varying time lengths. Setpoint programs may be stored to disk or to the instrument’s memory.

The fourth category of stored data is calibration storage, which is a file containing the instrument’s
analog input and output calibration. This file may be used to restore calibration in the event that a full
calibration, using a calibration source and/or meter, cannot be performed.

Video Recorder – User Manual 74

Performing Data Storage

Configuring the instrument to store the first category, Data Storage (process and diagnostic data) is done
through an Online menu entitled DATA STORAGE. All aspects of preparing a DOS formatted disk to
accept process and diagnostic data information are managed through this menu’s selections. Process
and diagnostic data may be stored on the same disk, but not along with other storage types (i.e.,
configuration, setpoint programs, or calibration).

The four types of process data are:

Trends - Data comprising the classic horizontal or vertically oriented time-varying traces that represent
process parameters.

Unit Data - Process parameter information collected and displayed in tabular or datalog format.

Alarms - A record of any alarms that activated while the instrument was monitoring and/or controlling
your process.

Events - A record of any discrete events that might have occurred while the instrument was monitoring
and/or controlling your process. Discrete events may occur, for example, in the instrument’s execution of
a set point profile.

When the instrument is On line and performing Data Storage, a separate and distinct disk file will be
established for each process data type along with a file for diagnostic errors. Each file will be
distinguished by a file extension as indicated in Table 3-11.

Data Type File extension

Trends .LNT

Unit Data .LNU

Alarm History .LNA

Discrete Event .LNE

Diagnostics .LND

You can specify which process data types are written to disk and whether or not diagnostic errors are
stored by setting up data storage schedules, accessible under a prompt entitled SET UP NEW
SCHEDULES under the DATA STORAGE menu. Up to Eight files may be written to disk while the
instrument performs Data Storage – four trend files, one unit data file, one alarm file, one event file, and
one diagnostics file.

SET UP NEW SCHEDULES lets you designate several other parameters, such as the data storage rate
(i.e., the distance in time between adjacent samples of a recorded process data parameter), the eight­character file names used to identify each process and diagnostic data file, and whether or not the Data
Storage takes place in continuous or batch modes. Data Storage files may be configured to “rollover”
after they have become full. That is, after the space on the disk for each file type has run out, all of the
oldest data on the disk is overwritten with the most recent data.

Programming and Operating Concepts

Initializing a ZIP disk

To activate the new data storage schedules that have been configured in the SET UP NEW
SCHEDULES menu requires you to “initialize” the DOS formatted disk to which process and diagnostic
data will be stored. This is done by executing a routine entitled INITIALIZE DISK, also found in the
DATA STORAGE menu. This task can also be done on a PC. The task of initializing a disk and
activating data storage schedules are one in the same.

ATTENTION

Initializing a disk is only necessary for performing Data Storage. You do not have to initialize a disk to perform
Configuration, Set Point Program, or Calibration Storage

When executing the INITIALIZE DISK menu prompt, you will observe two selections: USE NEW
SCHEDULES and USE CURRENT SCHEDULES. The “SCHEDULES” in both selections refer to the
data storage schedules prepared in the SET UP NEW SCHEDULES menu described earlier. USE NEW
SCHEDULES to initialize the disk to activate a newly configured data storage schedule for the very first
time. The only time you will USE NEW SCHEDULES again is after you have made any changes to the
way the data storage schedules have been configured. You must USE NEW SCHEDULES to initialize
the disk in order for these changes to take effect. USE CURRENT SCHEDULES to initialize a disk if the
disk will replace one that has become full. This will ensure that data being recorded continues
uninterrupted over the space of both the full and replacement disks. During the time when the full disk is
being replaced with a new disk, recorded data will be stored to the instrument’s memory buffer. Upon
completing initialization via the USE CURRENT SCHEDULES prompt, all buffered data will be written to
the new disk and data storage will resume, with no lapses of storage between disks.

Disk initialization allocates sections of the disk to each of the files you have elected to store per the SET
UP NEW SCHEDULES menu. Once the instrument completes initializing the disk, process and
diagnostic data recording begins immediately, indicated by a yellow-colored letter “S” in the lower right
hand corner of the instrument screen.

Pre-initializing a ZIPdisk on a PC

Pre-initializing a ZIP disk on the video recorder takes time, there is a more efficient way to do it : using
theSDI tool. The SDI tool is a very basic, straightforward Win 95/98/NT program that can be used to
quickly pre-initialize a ZIP disk on a PC. This tool is provided with the video recorder. Install it on your
PC, as per instructions on the floppy disk label.
Here are the 3 steps to follow when running the SDI utility.

Click on initialize

The next step to complete is to initialize the disk on the video recorder as you would have done normally,
as explained in the «Initializing a zip disk» section, except that this time, it will take just a few seconds.

Note: it is recommended to dedicate a ZIP disk to storage of data only and store configurations of
products on a separate disk.

Data Storage Status

The prompt DATA STORAGE STATUS, accessed from the Online DATA STORAGE menu item,
displays a calculation of how long a particular disk will last based on the configured data storage
schedule. Disk capacity is indicated in days, hours, and minutes remaining on the disk.

After the instrument has been Online and actively performing Data Storage to disk, a warning message
will appear when the disk reaches the default 90% capacity, or a user-specified capacity. Once a disk
has reached its programmed capacity, a DISK FULL message will be displayed.

Data storage considerations

In order to guarantee a proper operation of the instrument (e.g. no sample lost), there is a maximum load
that the video recorder should not overcome. This load can be theorically computed by considering the
number of data storage trends, live trends and live screens programmed and their associated sample
rate.

1 ) One live screen counts for one schedule per second. At least one live screen is present in the
instrument. A live screen is a display that require any measurement information to be built.

2 ) Each ENABLED Data Storage schedule has a user defined sample rate.

3 ) Each ENABLED Live Trend has the following sample rates :

Screen Size Schedule Sample Rate

5 Min Screen 1 Second

15 Minute Screen 3 Seconds

30 Minute Screen 6 Seconds

1 Hour 12 Seconds

2 Hours 24 Seconds

4 Hours 47 Seconds

24 Hours 279 Seconds (4.65 Minutes)

7 Days 1951 Seconds (32.5 Minutes)

31 Days 8640 Seconds (2.4 Hours)

Therefore, to guarantee a proper operation of the instrument, the following inequation should allways be

Process and Diagnostic Data Integrity

The instrument is equipped with several features to ensure data integrity. The instrument will not store
data to disk if its front door is open. A BEZEL OPEN message will appear on all displays and process
and diagnostic data meant for disk storage will be kept in the instrument’s memory buffer. Data
corruption and loss are, therefore, not issues if someone walks up to the instrument and simply removes
the Data Storage disk. Note that when performing Data Storage, the instrument writes to the disk only
once a minute. This ensures that the latest data is always on disk. In the event of a power failure, at
most one minute of data would be lost.

Performing Configuration Storage

Configuration storage is performed through a Program mode MAIN MENU prompt LOAD/STORE
CONFIG. Here, a file containing the instrument’s programming and configuration is created by executing
a routine called STORE CONFIG TO DISK. The applicable file extensions for configuration files are
.LNC.

Note that an instrument configuration file may also be created and stored to disk using optionally
purchased SCF Configuration Software. You do not need a live instrument to create a configuration file
using SCF.

Once stored to disk, the instrument configuration file may be downloaded into other instruments that
have an identical model number. This helps to greatly reduce the amount of time required to program
and configure multiple units sharing the same application. Having the instrument configuration on disk
can also drastically minimize down time in the event of an instrument failure. The file can be used to
program and configure a replacement unit within seconds.

Performing Set Point Program Storage

Refer to Section 5 of the manual for a detailed explanation of how Set Point Program Storage is
accomplished.

Programming Function Blocks and Features

4.2 Programming tips

• See Section 3 for general programming procedures.

• Before programming a function block’s input parameter with a CV’s (Calculated Value) output

parameter, you must program the CV first; otherwise, the CV’s output parameter will not be
available for programming.

• The function block SY (System Parameter) operates internally and has no menu. It automatically
produces outputs which reflect the status of alarms, data storage, diagnostics, and reference
junction temperature. These outputs can be programmed as inputs to function blocks. See Table

4.6 Enter Labels

Overview

Labeling lets you use the front panel buttons, a QWERTY keyboard, or barcode reader to assign
custom text identifiers to most data and functions to make them easily recognized on displays. Labeling
items makes programming and operation easier but is not required. You can assign all labels here or at
each individual programming menu (that is, at Program Analog Inputs, Program Alarms, etc.). For the
latter, you must enable labeling under ENABLE FEATURES in the main Program menu.

Entering labels with the front panel buttons

Use the Up Arrow and Down Arrow keys to select a character and the left arrow to move the cursor.
See Table 3-6 for these buttons’ functions. If you are entering several labels, this method can be
tedious because you must scroll through A-Z and 0-9 to pick each character. Consider using a
keyboard or barcode reader instead.

Entering labels with a QWERTY keyboard

Using a QWERTY keyboard is easier and faster if you are entering many labels. See Section 3.6 for
keyboard connection procedure.

To enter label with the keyboard:

1. Select Enter Labels.

2. Select the function block whose label you want to change.

3. Select the label you want to change (Table 4-3).

4. Press Enter to move cursor to the right side of the display.

5. Type in the new label with the keyboard. The instrument accepts A…Z, a…z, 0…9, (,), -, +, /, *, ^,
(.), =.

6. Press Enter to accept the new label.

Entering labels with a barcode reader

Using a barcode reader is easier and faster if you are entering many labels. See Section 3.6 for
barcode reader connection procedure.

To enter label with the barcode reader:

1. Select Enter Labels.

2. Select the function block whose label you want to change.

3. Select the label you want to change (Table 4-3).

4. Press Enter to move cursor to the right side of the display.

5. Scan in the new label with the barcode reader. Allowable characters are: 0…9, A…Z, -, +, /,

6. Press Enter to accept the new label.

After selecting ENTER LABELS, choose an item (such as Analog Inputs) to label. Use the prompts in
Table 4-3. All text and numeric keys may be used for labels; no characters are prohibited. To cancel an
entry, press the ESC key on the keyboard or press the Menu button on the front panel.
