DL305 Analog Components
There are a wide variety of Analog I/O modules available for use with the DL305
family of automation products. These modules are well suited for monitoring and
controlling various types of analog signals such as pressure, temperature, etc.
There are modules specifically designed for thermocouple and temperature input
requirements. No complex programming or module setup software is required.
Simply install the module, add a few lines to your RLL program, and you’re ready!

S F3--08AD — 8 channel input, 12-bit resolution
S F3--16AD — 16 channel input, 12-bit resolution
S D3--02DA — 2 channel output, 8-bit resolution
S F3--04DA--1 — 4 channel output, 12-bit resolution
S F3--04DAS — 4 channel isolated output, 12-bit resolution
There is also an 8 channel thermocouple input module that converts type E, J, K, R,
S, or T thermocouple signals into direct temperature readings. This module can also
convert other types of low-level (millivolt range) signals into digital values. The part
number for this module is F3--08THM--n, where n is the type of thermocouple. If you
want a millivolt input version,simply replace n with a 1 (0--50 mV)or a 2 (0 -- 100mV).
All versions offer 12-bit resolution.
The Temperature Input module provides 8 channels for direct temperature
measurement in either Celsius or Fahrenheit from --55_ to 150_ C. Order part
number F3--08TEMP. This module offers 12-bit resolution.

Physical Characteristics
The DL305 Analog Modules provide many features thatmake the modules easier to
use. For example, the terminal block can be removed making wiring a simple task.
You can also use our DINnector product line to organize your wiring even further
(see our catalog for details).
Some of the modules provide LEDs used to determine the signal level. Since there
are not enough LEDs to show all of the channels at once, there is a small switch
underneath the terminal cover that allows you to select the channel for monitoring.
Not all of the modules have this feature.
Most of the modules also have jumpersthat can be set to select between the various
types of signals. Each chapter will show how to set these jumpers for the selections
you need.

Selecting the Appropriate Module
The following tables provide a condensed version of the information you need to
select the appropriate module. The most important thing is to simply determine the
number of channels required and the signal ranges that must be supported. Once
you’ve determined these parameters, look in the specific chapter for the selected
module to determine the installation and operation requirements.

Wiring Guidelines
User Power Supply
Requirements
Your company may have guidelines for wiring and cable installation. If so, you should
check those before you begin the installation. Here are some general things to
consider.
S Use the shortest wiring route whenever possible.
S Use shielded wiring and ground the shield at the signal source. Do not
ground the shield at both the module and the source.
S Don’t run the signal wiring next to large motors, high current switches, or
transformers. This may cause noise problems.
S Route the wiring through an approved cable housing to minimize the risk
of accidental damage. Check local and national codes to choose the
correct method for your application.
The D3--04AD requires a separate power supply. The DL305 bases have built-in 24
VDC power supplies that provide up to 100 mA of current. If you only have one
analog module, you can use this power source instead of a separate supply. If you
have more than two analog modules, or you would rather use a separate supply,
choose one that meets the following requirements: 24 VDC ? 10%, Class 2, 65mA
current (or greater, depending on the number of modules being used.)

Custom Input
Ranges
Occasionally you may have the need to connect a transmitter with an unusual signal
range. By changing the wiring slightly and adding an external resistor to convert the
current to voltage, you can easily adapt this module to meet the specifications for a
transmitter that does not adhere to one of the standard input ranges. The following
diagram shows how this works.

D3--04AD 4-Channel Analog Input
Current Loop
Transmitter
Impedance
Standard 4 to 20 mA transmitters and transducers can operate froma wide variety of
power supplies. Not all transmitters are alike and the manufacturers often specify a
minimum loop or load resistance that must be used with the transmitter.
The D3--04AD provides 250 ohm resistance for each channel. If your transmitter
requires a load resistance below 250 ohms, then you do not have to make any
adjustments. However, if your transmitter requires a load resistancehigher than 250
ohms, then you need to add a resistor in series with the module.
Consider the following example for a transmitter being operated from a 36 VDC
supply with a recommended load resistance of 750 ohms. Since the module has a
250 ohm resistor, you need to add an additional resistor.

Module Operation
Before you begin writing the control program, it is important to take a few minutes to
understand how the module processes and represents the analog signals.
Channel Scanning
Sequence
The D3--04AD module supplies 1 channel of data per each CPU scan. Since there
are four channels, it can take up to four scans to get data for all channels. Once all
channels have been scanned, the process starts over with channel 1.
You do not have to select all of the channels. Unused channels are not processed, so
if you select only two channels, then each channel will be updated every other scan.

Store data
Even though the channel updates to the CPU are synchronous with the CPU scan,
the module asynchronously monitors the analog transmitter signal and converts the
signal to a 8-bit binary representation. This enables the module to continuously
provide accurate measurements without slowing down the discrete control logic in
the RLL program.

D3--04AD 4-Channel Analog Input
Understanding the
I/O Assignments
You may recall the D3--04AD module appears to the CPU as a 16-point module.
Some of the points are inputs to the CPU and some are outputs to the module. These
16 points provide:
S an indication of which channel is active.
S the digital representation of the analog signal.
Since all I/O points are automatically mapped into Register (R) memory, it is very
easy to determine the location of the data word that will be assigned to the module.

Since the module has 8-bit resolution, the analog signal is converted into 256
“pieces” ranging from 0 -- 255 (28). For example, with a 1 to 5V scale, a 1V signal
would be 0, and a 5V signal would be 255. This is equivalent to a a binary value of
0000 0000 to 1111 1111, or 00 to FF hexadecimal. The following diagram shows how
this relates to each signal range.

+5V

Each “piece” can also be expressed in
terms of the signal level by using the
Resolution = (H--L)/255
equation shown. The following table
shows the smallest signal levels that
could possibly result in a change in the
data value for each signal range.
H = high limit of the signal range
L = low limit of the signal range
Range Highest Signal Lowest Signal Smallest Change
1 to 5V 5V 1V 15.6 mV
4 to 20mA 20mA 4mA 62.7 mA
Now that you understand how the module and CPU work together to gather and
store the information, you’re ready to write the control program.

Identifying the

Since all channels are multiplexed into a single data word, the control program must
be setup to determine which channel is being read. Since the module provides input
points to the CPU, it is very easy to use the channel status bits to determine which
channel is being monitored.

Single Channel on
Every Scan
The following example shows a program that is designed to read a single channel of
analog data into a Register location on every scan. Once the data is in a Register,
you can perform math on the data, comparethe data againstpreset values, etc. This
example is designed to read channel 1. If you choose another channel, you would
have to add a rung (or rungs) that use the channelselect bits to select the channelfor
scanning. You would also have to change the rung that stores the data.

The DL305 CPUs perform math operations in

does not require the conversion.)
The channel selection inputs are used to let the
CPU know which channel has been loaded into the
accumulator. Channel 1 input has been used in the
example, but you could easily use a different input
for a different channel. By using these inputs to
control a DOUT instruction, you can easily move
the data to a storage register. The BCD value will
be stored in R400 and R401. (Two bytes are

D3--04AD 4-Channel Analog Input
The following instructions are required to scale the data. We’ll continue to use the
42.9 PSI example. In this example we’re using channel 1. Input 110 is the active
channel indicator for channel 1. Of course, if you were using a different channel, you
would use the active channel indicator point that corresponds to the channel you
were using.
This example assumes you have already read the analog data
and stored the BCD equivalent in R400 and R401

You probably noticed that the previous example yielded 42 PSI when the real value
should have been 42.9 PSI. By changingthe scalingvalue slightly, we can “imply” an
extra decimal of precision. Notice in the following example we’ve added another digit
to the scale. Instead of a scale of 100, we’re using 1000, which implies 100.0 for the
PSI range.

D3--04AD 4-Channel Analog Input
This example program shows how you can use the instructions to load the equation
constants into data registers. The example is written for channel 1, but you can
easily use a similar approach to use different scales for all channels if required.
You may just use the appropriate constants in the instructions dedicated for each
channel, but this method allows easier modifications. For example, you could easily
use an operator interface or a programming device to change the constants if they
are stored in Registers.

Analog and Digital
Value Conversions
Sometimes it is helpful to be able to quickly convert between the signal levels and the
digital values. This is especially helpful during machine startup or troubleshooting.
The following table provides formulas to make this conversion easier.
Range If you know the digital value ... If you know the analog signal
level ...
1 to 5V
4 to 20mA
A = (4D/255) + 1
A = (16D/255) + 4
D = (255/4)(A--1)
D = (255/16)(A--4)
For example, if you are using the 1 to 5V
range and you have measured the signal
D = (255/4)(A--1)
at 3V, you would use the following
formula to determine the digital value
that should be stored in the register
location that contains the data.
D = (255/4)(3V--1)
D = (63.75) (2)
D = 127.5 (or 128)
Now you have all the necessary information to get your analog module installed and
operating correctly!

The F3--04ADS Analog Input appears as a 16-point module. The module can be
installed in any slot configured for 16 points. See the DL305 User Manual for details
on using 16 point modules in DL305 systems. The limitation onthe number ofanalog
modules are:
57 ppm / _C maximum full scale
32° to 140° F (0° to 60_ C)
--4° to 158° F (--20° to 70_ C)
S The module should not be placed in the last slot of a rack (due to size
S For local and expansion systems, the available power budget and
constraints.)
16-point module usage are the limiting factors.

The module is set at the factory for a 4--20 mA signal on all four channels. If this is
acceptable you do not have to change any of the jumpers. The following diagram
shows how the jumpers are set.

notice several jumpers. The jumpers labeled +1
and +2 (located on the larger board, near the
terminal block) are used to select the number of
channels that will be used.
Without any jumpers the module processes one
channel. By installing the jumpers you can add
channels. The module is set from the factory for
four channel operation.
For example, if you install the +1 jumper, you
add one channel for a total of two. Now if you
install the +2 jumper youadd twomore channels
for a total of four.
Any unused channels are not processed so if
you only select channels 1, 2, and 3, channel 4
will not be active. The table shows which

Wiring Guidelines
User Power Supply
Requirements
Custom Input
Ranges
Your company may have guidelines for wiring and cable installation. If so, you should
check those before you begin the installation. Here are some general things to
consider.
S Use the shortest wiring route whenever possible.
S Use shielded wiring and ground the shield at the signal source. Do not
ground the shield at both the module and the source.
S Do not run the signal wiring next to large motors, high current switches,
or transformers. This may cause noise problems.
S Route the wiring through an approved cable housing to minimize the risk
of accidental damage. Check local and national codes to choose the
correct method for your application.
The F3--04ADS receives all power from the base. A separate power supply is not
required.
Occasionally you may have the need to connect a transmitter with an unusual signal
range. By changing the wiring slightly and adding an external resistor to convert the
current to voltage, you can easily adapt this module to meet the specifications for a
transmitter which does not adhereto one ofthe standard inputranges. The following
diagram shows how this works.

Current Loop
Transmitter
Impedance
Standard 4 to 20 mA transmitters and transducers can operate froma wide variety of
power supplies. Not all transmitters are alike and the manufacturers often specify a
minimum loop or load resistance that must be used with the transmitter.
The F3--04ADS provides 250 ohm resistance for each channel. If your transmitter
requires a load resistance below 250 ohms, then you do not have to make any
adjustments. However, if your transmitter requires a load resistancehigher than 250
ohms, then you need to add a resistor in series with the module.
Consider the following example for a transmitter being operated from a 36 VDC
supply with a recommended load resistance of 750 ohms. Since the module has a
250 ohm resistor, you need to add an additional resistor.

R = 750 - 250

Module Operation
Before you begin writing the control program, it is important to take a few minutes to
understand how the module processes and represents the analog signals.
Channel Scanning
Sequence
The F3--04ADS module supplies1 channel of data per each CPU scan. Since there
are four channels, it can take up to four scans to get data for all channels. Once all
channels have been scanned the process starts over with channel 1.
You do not have to select all of the channels. Unused channels are not processed, so
if you select only two channels, then each channel will be updated every other scan.

Scan N+1
Scan N+2
Scan N+3

Store data
Even though the channel updates to the CPU are synchronous with the CPU scan,
the module asynchronously monitors the analog transmitter signal and converts the
signal to a 12-bit binary representation. This enables the module to continuously
provide accurate measurements without slowing down the discrete control logic in
the RLL program.

Understanding the
I/O Assignments
You may recall the F3--04ADS module appears to the CPU as a 16-point module.
These 16 points provide:
S an indication of which channel is active.
S the digital representation of the analog signal.
Since all I/O points are automatically mapped into Register (R) memory, it is very
easy to determine the location of the data word that will be assigned to the module.

Since the module has 12-bit resolution, the analog signal is converted into 4096
“pieces” ranging from 0 -- 4095 (212). For example, with a 0 to 10V scale, a 0V signal
would be 0, and a 10V signal would be 4095. This is equivalent to a a binary value of
0000 0000 0000 to 1111 1111 1111, or 000 to FFF hexadecimal. The following

Since all channels are multiplexed into a single data word, the control program must
be setup to determine which channel is being read. Since the module provides input

The following example shows a program that is designed to read a single channel of
analog data into a Register location on every scan. Once the data is in a Register,
you can perform math on the data, comparethe data againstpreset values, etc. This
example is designed to read channel 1. Since you use jumpers to select the number
of channels to scan, this is the only channel that you can use in this manner.

This rung loads the data into the accumulator on
every scan. (You can use any permissive contact.)
The DL305 CPUs perform math operations in
BCD. This instruction converts the binary data to
BCD. (You can omit this step if your application
does not require the conversion.)
The active channel inputs are used to let the CPU
know which channel has been loaded into the
accumulator. (Since you cannot isolate the
individual channels for scanning, channel 1 is the
only channel that can be used in this manner.) By
using the input to control a DOUT instruction, you
can easily move the data to a storage register. The
BCD value will be stored in R400 and R401. (Two
bytes are required for four digit BCD numbers.)

Alternating Scans
The following example shows a program designed to read any of the available
channels of analog data into Register locations. Once the data is in a Register, you
can perform math on the data, compare the data against preset values, etc. Since
the DL305 CPUs use 8-bit word instructions, you have to move the data in pieces. It’s
simple if you follow the example.

This rung loads the eight least significant data bits
into the accumulator from Register 001.
Temporarily store the bits to Register 500. Since
the most significant bits were loaded into 501, now
R500 and R501 contain all twelve bits in order.
Now that all the bits are stored, load all twelve bits
into the accumulator.
Math operations are performed in BCD. This
instruction converts the binary data to BCD. (You
can omit this step if your application does not

The channel selection inputs are used to let the
CPU know which channel has been loaded into the

DOUT instruction, you can easily move the data to

stores the data in two bytes. (Two bytes are

The following instructions are required to scale the data. We’ll continue to use the

channel indicator for channel 1. Of course, if you were using a different channel, you
would use the active channel indicator point that corresponds to the channel you

should have been 42.9 PSI. By changingthe scalingvalue slightly, we can “imply” an
extra decimal of precision. Notice in the following example we’ve added another digit
to the scale. Instead of a scale of 100, we’re using 1000, which implies 100.0 for the

F3--04ADS 4-Channel Isolated Analog Input
This example program shows how you can use the instructions to load these
equation constants into data registers. The example is written for channel 1, but you
can easily use a similar approach to use different scales for all channels if required.
You may just use the appropriate constants in the instructions dedicated for each
channel, but this method allows easier modifications. For example, you could easily
use an operator interface or a programming device to change the constants if they
are stored in Registers.

The module is set at the factory for a 4--20 mA signal on all eight channels. If this is
acceptable you do not have to change any of the jumpers. The following diagram
shows how the jumpers are set.
Channels
+4
+2
+1
you’ll notice several jumpers. The
jumpers labeled +1, +2 and +4 are used
to select the number of channels that will
be used. Without any jumpers the
module processes one channel (channel
1). By installing the jumpers you can add
channels. The module is set from the
factory for eight channel operation.
For example, if you install the +1 jumper,
you add one channel for a total of two.
Now if you install the +2 jumper you add
two more channels for a total of four.
Any unused channels are not processed
so if you only select channels 1--4, then
the last four channels will not be active.
The following table shows which jumpers
to install.

Wiring Guidelines

Requirements
Current Loop

Impedance
Your company may have guidelines for wiring and cable installation. If so, you should
check those before you begin the installation. Here are some general things to
consider.
S Use the shortest wiring route whenever possible.
S Use shielded wiring and ground the shield at the signal source. Do not
ground the shield at both the module and the source.
S Don’t run the signal wiring next to large motors, high current switches, or
transformers. This may cause noise problems.
S Route the wiring through an approved cable housing to minimize the risk
of accidental damage. Check local and national codes to choose the
correct method for your application.
The F3--08AD receives all power from the base. A separate power supply is not
required.
Standard 4 to 20 mA transmitters and transducers can operate froma wide variety of
power supplies. Not all transmitters are alike and the manufacturers often specify a
minimum loop or load resistance that must be used with the transmitter.
The F3--08AD provides 250 ohm resistance for each channel. If your transmitter
requires a load resistance below 250 ohms, then you do not have to make any
adjustments. However, if your transmitter requires a load resistancehigher than 250
ohms, then you need to add a resistor in series with the module.
Consider the following example for a transmitter being operated from a 36 VDC
supply with a recommended load resistance of 750 ohms. Since the module has a
250 ohm resistor, you need to add an additional resistor.
R = Tr - Mr
R = 750 - 250

F3--08AD 8-Channel Analog Input
Module Operation
Before you begin writing the control program, it is important to take a few minutes to
understand how the module processes and represents the analog signals.
Channel Scanning
Sequence
The F3--08AD module supplies1 channel of data per each CPU scan. Since there
are eight channels, it can take up to eight scans to get data for all channels. Once all
channels have been scanned the process starts over with channel 1.
You do not have to select all of the channels. Unused channels are not processed, so
if you select only four channels, then the channels will be updated within four scans.
Scan
I/O Update
Channel 1
Channel 2
.
.
.
Channel 8
Channel 1
Even though the channel updates to the CPU are synchronous with the CPU scan,
the module asynchronously monitors the analog transmitter signal and converts the
signal to a 12-bit binary representation. This enables the module to continuously
provide accurate measurements without slowing down the discrete control logic in
the RLL program.

Understanding the
I/O Assignments
You may recall the F3--08AD module appears to the CPU as a 16-point module.
These 16 points provide:
S an indication of which channel is active.
S the digital representation of the analog signal.
Since all I/O points are automatically mapped into Register (R) memory, it is very
easy to determine the location of the data word that will be assigned to the module.

Since all channels are multiplexed into a single data word, the control program must
be setup to determine which channel is being read. Since the module provides input
points to the CPU, it is very easy to use the active channel status bits to determine
which channel is being monitored.

Single Channel on
Every Scan
The following example shows a program that is designed to read a single channel of
analog data into a Register location on every scan. Once the data is in a Register,
you can perform math on the data, comparethe data againstpreset values, etc. This
example is designed to read channel 1. Since you use jumpers to select the number
of channels to scan, this is the only channel that you can use in this manner.

The DL305 CPUs perform math operations in

Since the active channel indicators are all off when
channel 1 is being read, you would not have to use
them. (Since you cannot isolate the individual
channels for scanning, channel 1 is the only
channel that can be used in this manner.) The
DOUT instruction moves the data to a storage

The following instructions are required to scale the data. We’ll continue to use the

input 116 are all off when channel 1 data is being read. Of course, if youwere using a
different channel, you would use the active channel indicator point combination that
corresponds to the channel you were using.

should have been 42.9 PSI. By changingthe scalingvalue slightly, we can “imply” an

This example program shows how you can use the instructions to load these

you could easily use a similar approach to use different scales for all channels if
required.
You could just use the appropriate constants in the instructions dedicated for each
channel, but this method allows easier modifications. For example, you could easily
use an operator interface or a programming device to change the constants if they
are stored in Registers.

If you examine the rear of the module,
you’ll notice several jumpers. The
+8 +4 +2
+1
jumpers labeled +1, +2, +4 and +8 are
used to select the number of channels
that will be used. Without any jumpers
the module processes one channel. By
installing the jumpers you can add
channels. The module is set from the
Number of
Channels
factory for sixteen channel operation.
Any unused channels are not processed
so if you only select channels 1--8, then
Jumpers installed as shown
selects 16-channel operation
the last eight channels will not be active.
The following table shows which jumpers
to install.

Selecting Input
Signal Ranges
As you examined the jumper settings, you may have noticed there are current
jumpers for each individual channel. These jumpers allow you to select the type of
signal (voltage or current).
The span and polarity jumpers are used to select the signal range. The polarity and
span selection affect all the channels. For example, if you select unipolar operation
and a 10V span, you can use both 0 --10V and 0--20 mA signals at the same time.
Channels that will receive 0--20 mA signalsshould have thecurrent jumper installed.
The following table shows the jumper selections for the various ranges. (Only
channel 1 is used in the example, but all channels must be set.)

Gain Jumpers
Variable Gain
Adjustment
You do not have to change the Gain jumpers. These jumpers are installed to allow
the ranges shown previously. Note, if you change these jumpers the module will not
operate the way you expect.
If you look at the terminal block closely,
you’ll notice a small hole conceals an
adjustment potentiometer. This small
potentiometer is used to adjust the gain
for certain situations.
For example, if you have 0--5V
transmitters you have to use the 0--10V
scale on the module. Since the module
converts the signal to a digital value
between 0 and 4095, a 5V signal would
only yield a value of 2048. Fortunately,
the variable gain feature provides a
simple solution. Just complete the
following steps.
1. Install a jumper on the gain adjustment pins. (This jumper location is
labeled ADJ.)
2. Apply 5V to one of the channels.
3. Use a handheld programmer or DirectSOFT to monitor the input register
that contains the analog data. (If you’re not familiar with this procedure, wait
until you read the section on Writing the Control Program. This will show
you how to get data into a register. You can come back to this procedure
later.)
4. Adjust the potentiometer until the register value reads 4094 or 4095. The
potentiometer is turned clockwise to increase the gain.

Now the module has been adjusted so a 5V signal provides a digital value of 4095
instead of 2048.

Connecting the Field Wiring
Wiring Guidelines
User Power Supply
Requirements
Your company may have guidelines for wiring and cable installation. If so, you should
check those before you begin the installation. Here are some general things to
consider.
S Use the shortest wiring route whenever possible.
S Use shielded wiring and ground the shield at the signal source. Do not
ground the shield at both the module and the source.
S Don’t run the signal wiring next to large motors, high current switches, or
transformers. This may cause noise problems.
S Route the wiring through an approved cable housing to minimize the risk
of accidental damage. Check local and national codes to choose the
correct method for your application.
The F3--16AD receives all power from the base. A separate power supply is not
required.

Custom Input
Ranges
Occasionally you may have the need to connect a transmitter with an unusual signal
range. By changing the wiring slightly and adding an external resistor to convert the
current to voltage, you can easily adapt this module to meet the specifications for a
transmitter that does not adhere to one of the standard input ranges. The following
diagram shows how this works.

Current Loop
Transmitter
Impedance
Standard 4 to 20 mA transmitters and transducers can operate froma wide variety of
power supplies. Not all transmitters are alike and the manufacturers often specify a
minimum loop or load resistance that must be used with the transmitter at the various
voltages.
The F3--16AD provides 500 ohm resistance for each channel. If your transmitter
requires a load resistance below 500 ohms, then you do not have to make any
adjustments. However, if your transmitter requires a load resistancehigher than 500
ohms, then you need to add a resistor in series with the module.
Consider the following example for a transmitter being operated from a 36 VDC
supply with a recommended load resistance of 750 ohms. Since the module has a
500 ohm resistor, you need to add an additional resistor.
R = Tr - Mr
R = 750 - 500

Module Operation
Before you begin writing the control program, it is important to take a few minutes to
understand how the module processes and represents the analog signals.
Channel Scanning
Sequence
The F3--16AD module supplies 1 channel of data per each CPU scan. Since there
are sixteen channels, it can take up to sixteen scans to get data for all channels.
Once all channels have been scanned the process starts over with channel 1.
You do not have to select all of the channels. Unused channels are not processed, so
if you select only eight channels, then the channels will be updated within eight
scans.

Store data
Even though the channel updates to the CPU are synchronous with the CPU scan,
the module asynchronously monitors the analog transmitter signal and converts the
signal to a 12-bit binary representation. This enables the module to continuously
provide accurate measurements without slowing down the discrete control logic in
the RLL program.

Understanding the
I/O Assignments
You may recall the F3--16AD module appears to the CPU as a 16-point module.
These 16 points provide:
S an indication of which channel is active.
S the digital representation of the analog signal.
Since all I/O points are automatically mapped into Register (R) memory, it is very
easy to determine the location of the data word that will be assigned to the module.

Since the module has 12-bit resolution, the analog signal is converted into 4096
“pieces” ranging from 0 -- 4095 (212). For example, with a 0 to 10V scale, a 0V signal
would be 0, and a 10V signal would be 4095. This is equivalent to a a binary value of
0000 0000 0000 to 1111 1111 1111, or 000 to FFF hexadecimal. The following
diagram shows how this relates to each signal range.

NOTE: When you use 4--20mA signals, you have to use the 0--20mA scale. You do
not have resolution of 4096 if the 4--20mA signal is present. In this case, the range is
819 to 4095. This is because a 0 still represents 0mA, not 4mA.
Each “piece” can also be expressed in
terms of the signal level by using the
Resolution =
H - L
4095
equation shown. The following table
shows the smallest signal levels that will
possibly result in a change in the data
value for each signal range.
H = high limit of the signal range
L = low limit of the signal range

Writing the Control Program
Identifying the
Data Locations
Since all channels are multiplexed into a single data word, the control program must
be setup to determine which channel is being read. Since the module provides input
points to the CPU, it is very easy to use the active channel status bits to determine
which channel is being monitored.

F3--16AD 16-Channel Analog Input
Example Program
The following example shows a program designed to read any of the available
channels of analog data into Register locations. Once the data is in a Register, you
can perform math on the data, compare the data against preset values, etc. Since
the DL305 CPUs use 8-bit word instructions, you have to move the data in pieces. It’s
pretty simple if you follow the example.

This rung loads the channel ID bits into the

Convert the channel ID status to BCD. (We’ll use
relational contacts later to make the chanel
selection much easier.)
Store the channel ID in R600. (Note, you don’t
absolutely have to do it this way. If you use R600,
then you can’t use Timer/Counter 600. You could
just use the channel indicators. See the Store
Channel 1 example that follows.)
This rung loads the four most significant data bits into
the accumulator from Register 011 on every scan.
Temporarily store the bits to Register 501.
This rung loads the eight least significant data bits

Temporarily store the bits to Register 500. Since
the most significant bits were loaded into 501, now
R500 and R501 contain all twelve bits in order.
Now that all the bits are stored, load all twelve bits
into the accumulator.
Math operations are performed in BCD. This
instruction converts the binary data to BCD. (You
can omit this step if your application does not
require the conversion.)
The channel selection inputs are used to let the
CPU know which channel has been loaded into the
accumulator. By using these inputs to control a
DOUT instruction, you can easily move the data to
a storage register. Notice the DOUT instruction
stores the data in two bytes. (Two bytes are
required for four digit BCD numbers.)
This rung shows how you would use the channel
indicator inputs as contacts to control the channel
selection.
This rung shows an easier way. Earlier we loaded
the channel ID bits (in BCD format) into R600. Now
we can use one relational contact to examine this
value. However, this method uses the register
associated with Timer/Counter 600. If you use this
method, make sure you don’t use the
Timer/Counter associated with the register
elsewhere in the program.

Scaling the Input

Most applications usually require
measurements in engineering units,
which provide more meaningful data.
This is accomplished by using the
conversion formula shown.

42.9 PSI.

F3--16AD 16-Channel Analog Input
The following instructions are required to scale the data. (We’ll continue to use the
42.9 PSI example.) In this example we’re using channel 1. The active channel
indicator inputs are all off when channel 1 data is being read. Of course, if you were
using a different channel, you would use the active channel indicator point
combination that corresponds to the channel you were using.
This example assumes you have already read the analog data
and stored the BCD equivalent in R400 and R401

You probably noticed the previous example yielded 42 PSI when the real value
should have been 42.9 PSI. By changingthe scalingvalue slightly, we can “imply” an
extra decimal of precision. Notice in the following example we’ve added another digit
to the scale. Instead of a scale of 100, we’re using 1000, which implies 100.0 for the
PSI range.
This example assumes you have already read the analog data
and stored the BCD equivalent in R400 and R401

F3--16AD 16-Channel Analog Input
This example program shows how you can use the instructions to load these
equation constants into data registers. The example is written for channel 1, but you
can easily use a similar approach to use different scales for all channels if required.
You may just use the appropriate constants in the instructions dedicated for each
channel, but this method allows easier modifications. For example, you could easily
use an operator interface or a programming device to change the constants if they
are stored in Registers.

Scaling on a DL350
with a
Conventional
DL305 Base
The example below shows how to scale input data from an F3--04ADS Analog
module in the 20--27/120--127 address slot. This module must be placed in a 16 bit
slot in order to work.

This loads the upper byte of the analog data from
the module.
SHFL K8 shifts the data to the left eight places to
make room for the lower byte of data.
The ORF X20 brings the lower byte of data from
the module into the accumulator. At this time there
is a full word of data from the analog module in the
accumulator.
The ANDD Kfff masks off the twelve least
significant bits of data from the word. This is the
actual analog value.
The BCD command converts the data to BCD
format.
The scaled value is stored in V3010 with an
implied decimal.

Rung 3 scales a 0 to 200 range of a transducer
over the 4096 counts. The raw analog value is
loaded to the accumulator from V3001
(Channel #1).
It is then multiplied by 2000. The additional zero
provides a higher degree of resolution.
It is then divided by 4096, which is the resolution of
the module.
The scaled value is stored in V3010 with an
implied decimal.

Broken Transmitter
Detection
If you use 4--20mA signals you can easily check for broken transmitter conditions.
Since you have to use the 0--20mA range and the lowest signal for the 4--20mA
transmitter is 4mA, the lowest digital value for the signal is not 0, but instead is 819.
If the transmitter is workingproperly thesmallest valueyou should ever see is 819. If
you see a value of less than about 750 (allowing for tolerance), then you know the
transmitter is broken.

Temporarily store the bits to Register 500. Since
the most significant bits were loaded into 501, now
R500 and R501 contain all twelve bits in order.
Now that all the bits are stored, load all twelve bits
into the accumulator.
Math operations are performed in BCD. This
instruction converts the binary data to BCD. (You
can omit this step if your application does not
require the conversion.)
The DOUT instruction copies the accumulator data
to R400 and R401. Since the data is still in the
accumulator, we can compare it against a
constant. Since the minimum value for a 4mA
signal is 819 (minus the module tolerance), we can
choose a value for the compare. We picked 100,
but you could choose something else from 0 to
about 750.
Flags 773 and 774 are used with the Compare
instruction. In this example if the analog value is
less than or equal to 100, then output 040 is turned
on.
You may want to latch 040 to catch intermittent
broken transmitters.
