DL305 Analog Components

Getting Started

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!

The following is a list of the types of analog input and analog output modules that are available.

S D3–04AD — 4 channel input, 8-bit resolution S F3–04ADS — 4 channel isolated input, 12-bit resolution 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 that make 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 jumpers that 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.

The D3–04AD 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 on the number of analog modules are:

S For local and expansion systems, the available power budget and

16-point module usage are the limiting factors.

Page 27

Setting the Module Jumpers

There are four jumpers located on the module that select between 1–5V and 4–20 mA signals. The module is shipped from the factory for use with 1–5V signals.

If you want to use 4 – 20 mA signals, you have to install a jumper. No jumper is required for 1 – 5V operation. Each channel range may be selected independently of the others.

Connecting the Field Wiring

Wiring Guidelines

User Power Supply Requirements

Y our 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.)

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 2 0 m A transmitters and transducers can operate from a 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 resistance higher 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.

Note 1: Terminate all shields of the cable at their respective signal source.

Note 2: Unused channels should be shorted to 0V or have the Jumper installed for current input for best noise immunity.

Note 3: When a differential input is not used 0V should be connected to the – of that channel.

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.

Y ou 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.

Understanding the I/O Assignments

D3–04AD

4-Channel Analog Input

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.

The upper register also contains two additional outputs that can be used to choose a single channel for scanning. These outputs are ignored if the channel scan output is turned on.

The first four points of the upper register are used as inputs to tell the CPU which channel is being processed. (Remember, the previous bits only tell the module which channels to scan.)

Since the module has 8-bit resolution, the analog signal is converted into 256 “pieces” ranging from 0 – 255 (2

). 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.

Each “piece” can also be expressed in terms of the signal level by using the

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.

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 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 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, compare the data against preset 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 channel select bits to select the channel for scanning. You would also have to change the rung that stores the data.

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.

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.

Scaling the Input Data

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

The following example shows how you would use the analog data to represent pressure (PSI) from 0 to 100. This example assumes the analog value is 110, which is slightly less than half scale. This should yield approximately 43 PSI.

Units = (A/255)*S

Units = value in Engineering Units A = Analog value (0 – 255) S = Engineering unit range

Units = (A/255)*S

4-Channel Analog Input

D3–04AD

Units = (110/255)*100

Units = 43

Here is how you would write the program to perform the engineering unit conversion. This example assumes you have the analog data in BCD format data loaded into V3000.

NOTE: This example uses SP1, which is always on. You could also use an X, C, etc. permissive contact.

Sometimes it i s 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.

A = (4D/255) + 1

A = (16D/255) + 4

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)

S The module should not be placed in the last slot of a rack (due to size

constraints.)

S For local and expansion systems, the available power budget and

16-point module usage are the limiting factors.

Selecting the Number of Channels

UNIPOLAR BIPOLAR

If you examine the rear of the module, you’ll 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 you add two more 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 jumpers to install.

Wiring Guidelines

User Power Supply Requirements

Custom Input Ranges

Y our 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 adhere to one of the standard input ranges. The following diagram shows how this works.

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 resistance higher than 250 ohms, then you need to add a resistor in series with the module.

Module Operation

Channel Scanning Sequence

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.

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.

Y ou 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 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 (2

). 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.

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, compare the data against preset 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.

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.

You probably noticed the previous example yielded 42 PSI when the real value should have been 42.9 PSI. By changing the scaling value 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

Writing the Control Program (DL350)

3–17

Reading Values: Pointer Method and Multiplexing

Pointer Method

There are two methods of reading values for the DL350:

S The pointer method (all system bases must be D3–xx–1 bases to

support the pointer method)

S Multiplexing

You must use the multiplexing method with remote I/O modules (the pointer method will not work). You can use either method when using DL350, but for ease of programming it is strongly recommended that you use the pointer method.

NOTE: Do not use the pointer method and the PID PV auto transfer from I/O module function together for the same module. If using PID loops, use the pointer method and ladder logic code to map the analog input data into the PID loop table.

The DL350 has special V-memory locations assigned to each base slot that greatly simplifies the programming requirements. These V-memory locations allow you to:

S specify the data format S specify the number of channels to scan S specify the storage locations

The example program shows how to setup these locations. Place this rung anywhere in the ladder program or in the Initial Stage if you are using RLL

PLUS

instructions. This is all that is required to read the data into V-memory locations. Once the data is in V -memory, you can perform math on the data, compare the data against preset values, and so forth. V2000 is used in the example, but you can use any user V-memory location. In this example the module is installed in slot 2. You should use the V-memory locations for your module placement.

Loads a constant that specifies the number of channels to scan and the data format. The upper byte, most significant nibble (MSN) selects the data format (i.e. 0=BCD, 8=Binary), the LSN selects the number of channels (i.e. 1, 2, 3, 4).

The binary format is used for displaying data on some operator interfaces.

Special V-memory location assigned to slot 2 that contains the number of channels to scan.

This loads an octal value for the first V-memory location that will be used to store the incoming data. For example, the O2000 entered here would designate the following addresses. Ch1 - V2000, Ch2 - V2001, Ch3 - V2002, Ch 4 - V2003

The octal address (O2000) is stored here. V7672 is assigned to slot 2 and acts as a pointer, which means the CPU will use the octal value in this location to determine exactly where to store the incoming data.

The table shows the special V-memory locations used with the DL350. Slot 0 (zero) is the module next to the CPU, slot 1 is the module two places from the CPU, and so on. Remember, the CPU only examines the pointer values at these locations after a mode transition. The pointer method is supported on expansion bases up to a total of 8 slots away from the DL350 CPU. The pointer method is not supported in slot 8 of a 10 slot base.

Scaling the Input Data

Most applications usually require measurements in engineering units,

Units + A

H * L

4095

which provide more meaningful data. This is accomplished by using the conversion formula shown.

You may have to make adjustments to the formula depending on the scale you choose for the engineering units.

H = high limit of the engineering

unit range

L = low limit of the engineering

unit range

A = Analog value (0 – 4095)

For example, if you wanted to measure pressure (PSI) from 0.0 to 99.9 then you would have to multiply the analog value by 10 in order to imply a decimal place when you view the value with the programming software or a handheld programmer. Notice how the calculations differ when you use the multiplier.

Here is how you would write the program to perform the engineering unit conversion. This example assumes you have BCD data loaded into the appropriate V-memory locations using instructions that apply for the model of CPU you are using.

NOTE: This example uses SP1, which is always on. You could also use an X, C, etc. permissive contact.

Jumper Locations

Selecting the Number of Channels

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

If you examine the rear of the module, 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

User Power Supply Requirements

Current Loop Transmitter Impedance

Y our 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.

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 resistance higher than 250 ohms, then you need to add a resistor in series with the module.

Module Operation

Channel Scanning Sequence

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.

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.

Y ou 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.

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 the module has 12-bit resolution, the analog signal is converted into 4096 “pieces” ranging from 0 – 4095 (2

). For example, with a 4 – 20 mA scale, a 4 mA signal would be 0, and a 20 mA signal would be 4095. This is equivalent to 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.

Each “piece” can also be expressed in terms of the signal level by using the equation shown. The following table shows the smallest signal levels that will result in a change in the data value for each signal range.

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, compare the data against preset 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.)

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 DOUT1 instruction moves 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.)

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.)

This rung loads the four most significant data bits into the accumulator from Register 011 on every scan. (You could use any permissive contact.)

Temporarily store the bits to Register 501.

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 require the conversion.)

The channel indicator 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.)

Scaling the Input Data

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

The following example shows how you would use the analog data to represent pressure (PSI) from 0 to 100. This example assumes the analog value is

1760. This should yield approximately

42.9 PSI.

42.9 PSI example. In this example we’re using channel 1. Input 1 14, input 115, and input 116 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 program shows how you can use the instructions to load these equation constants into data registers. The example was written for channel 1, but 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.

Pointer Method

There are two methods of reading values for the DL350:

S The pointer method (all system bases must be D3–xx–1 bases to

support the pointer method)

S Multiplexing

The DL350 has special V-memory locations assigned to each base slot that greatly simplifies the programming requirements. These V-memory locations allow you to:

S specify the data format S specify the number of channels to scan S specify the storage locations

The example program shows how to setup these locations. Place this rung anywhere in the ladder program or in the Initial Stage if you are using RLL

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 signals should have the current 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.)

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. This jumper will remain installed after the gain adjustment .)

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.

Hole

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

Wiring Guidelines

User Power Supply Requirements

Y our 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.

Current Loop Transmitter Impedance

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 resistance higher 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.

F3–16AD 16-Channel Analog Input

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.

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.

Y ou 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.

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.

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

H = high limit of the signal range L = low limit of the signal range

Writing the Control Program (DL330 / DL340)

F3–16AD 16-Channel Analog Input

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.
