Allocation of I/O Words
Input bits
Expansion Units and Expansion I/O Units are allocated I/O bits in the order
the Units are connected starting from the CPU Unit. When the power to the
CPU Unit is turned ON, the CPU Unit checks for any Expansion Units and
Expansion I/O Units connected to it and automatically allocates I/O bits

Each CP1W-AD041/CPM1A-AD041 Analog Input Unit provides four analog
inputs.
• The analog input signal ranges are 0 to 5 V, 1 to 5 V, 0 to 10 V, -10 to +10
V, 0 to 20 mA, and 4 to 20 mA. The resolution is 1/6,000. The open-circuit
detection function is activated in the ranges of 1 to 5 V and 4 to 20 mA.
• The Analog Input Unit uses four input words and two output words, so a
maximum of three Units can be connected.

two’s complement.
If an input is below the range
(i.e., less than 3.2 mA), the
open-circuit detection function is activated and the data
becomes 8,000.
For analog inputs, the averaging function operates when the averaging bit is
set to 1. The averaging function outputs the average (a moving average) of
the last eight input values as the converted value. If there is only a slight variation in inputs, it is handled by the averaging function as a smooth input.
The averaging function stores the average (a moving average) of the last eight
input values as the converted value. Use this function to smooth inputs that
vary at a short interval.
Open-circuit Detection
Function
The open-circuit detection function is activated when the input range is set to
1 to 5 V and the voltage drops below 0.8 V, or when the input range is set to 4
to 20 mA and the current drops below 3.2 mA. When the open-circuit detection function is activated, the converted data will be set to 8,000.
The time for enabling or clearing the open-circuit detection function is the
same as the time for converting the data. If the input returns to the convertible
range, the open-circuit detection is cleared automatically and the output
returns to the normal range.

(1) Connect the shield to the FG terminal to prevent noise.
(2) When an input is not being used, short the + and – terminals.
(3) Separate wiring from power lines (AC power supply lines, high-voltage
lines, etc.)
(4) When there is noise in the power supply line, install a noise filter on the
input section and the power supply.
(5) Refer to the following information on open circuits when using voltage inputs.

For example, if analog input device 2 is outputting 5 V and the same power
supply is being used as shown above, about 1/3, or 1.6 V, will be applied at
the input for input device 1.
Consider the following information on open input circuits when using voltage
inputs. Either use separate power supplies, or install an isolator at each input.
If the same power supply is used as shown in the following diagram and an
open circuit occurs at point A or B, an unwanted current flow will occur as
shown by the dotted lines in the diagram, creating a voltage at the other input
of about 1/3 to 1/2. If the 1 to 5-V range is being used, the open-circuit detection function will not operate. Also, if there is an open circuit at C, the open-circuit detection function will not operate because the negative sides are the
same.
3. Creating the Ladder Program
Allocating I/O Words
Four input words and two output words are allocated from the next words following the last I/O words allocated to the CPU Unit or an existing Expansion
Unit or Expansion I/O Unit.

• The Analog Input Unit will not start converting analog I/O values until the
range code has been written.
• Once the range code has been set, it is not possible to change the setting
while power is being supplied to the CPU Unit. To change the I/O range,
turn the CPU Unit OFF then ON again.
Averaging
Set whether averaging is to be used for set data. When the averaging bit is set
to 1, the average (moving average) for the past eight inputs is output as conversion data.
Reading Analog Input
Conversion Values
Read the conversion value storage area with the ladder program. With word m
as the last input word allocated to the CPU Unit or an already-connected
Expansion Unit, the A/D conversion data will be output to the following words
m+1 to m+4.
Startup Operation
After the power is turned ON, it will require two cycle times plus approximately
50 ms before the first conversion data is stored in the input words. Therefore,
create a program as shown below, so that when operation begins simultaneously with startup it will wait for valid conversion data.
The analog input data will be 0000 until the initial processing is completed.

Handling Unit Errors
• When an error occurs in an Analog Input Unit, the analog input conversion
data becomes 0000.

Section 7-3
Analog Output Units
• Expansion Unit errors are output to bits 0 to 6 of word A436. The bits are
allocated from A436.00 in order starting with the Unit nearest the CPU
Unit. Use these flags in the program when it is necessary to detect errors.

(1) Connect the shield to the FG terminal to prevent noise.
(2) Separate wiring from power lines (AC power supply lines, high-voltage
lines, etc.)
(3) When there is noise in the power supply line, install a noise filter on the
input section and the power supply.
(4) When external power is supplied (when range codes are set), or when the
power is interrupted, there may be a pulse status analog output of up to
1 ms. If this status is a problem, take the following measures.
• Turn ON the power to the CP1L CPU Unit, check the operation status,
and then turn ON the power at the load.
• Turn OFF the power to the load and then turn OFF the power to the
CP1L CPU Unit.

• The Analog Output Unit will not start converting analog I/O values until the
range code has been written. The output will be 0 V or 0 mA.
• From when the range code has been written until data in the analog output convertible range is written, 0 V or 0 mA will be output in the 0 to 10 V,
-10 to +10 V, and 0 to 20 mA ranges, and 1 V or 4 mA will be output in the
1 to 5 V and 4 to 20 mA ranges.
• Once the range code has been set, it is not possible to change the setting
while power is being supplied to the CPU Unit. To change the I/O range,
turn the CPU Unit OFF then ON again.
436
Section 7-3
Analog Output Units
Writing Analog Output Set
Values
The ladder program can be used to write data to the output word where the
set value is stored. The output word will be “n+1” when “n” is the last output
word allocated to the CPU Unit, or previous Expansion Unit or Expansion I/O
Unit.
Startup Operation
After power is turned ON, it will require two cycle times plus approximately 50
ms before the first data is converted.
The following table shows the output status after the initial processing is completed.

Therefore, create a program as shown below, so that when operation begins
simultaneously with startup it will wait for valid set data.
TIM 005 will start as soon as power
turns ON. After 0.1 to 0.2 s (100 to
200 ms), the Completion Flag for
TIM 005 will turn ON, and the data
stored in DM 0100 will be moved to
IR 102 as the conversion data for
analog output 1.

Handling Unit Errors
• When an error occurs at the Analog Output Unit, the analog output will be
0 V or 0 mA. If a CPU Unit fatal error occurs when analog outputs are set
in the 1 to 5 V or 4 to 20 mA range, 0 V or 0 mA will be output for a CPU
error I/O bus error, and 1 V or 1 mA will be output for all other errors.
• Expansion Unit errors are output to bits 0 to 6 of word A436. The bits are
allocated from A436.00 in order starting with the Unit nearest the CPU
Unit. Use these flags in the program when it is necessary to detect errors.

Note
(1) For analog outputs it is possible to use both voltage outputs and current
outputs at the same time, but the total current output must not exceed
21 mA.
(2) Use 2-core shielded twisted-pair cables.
(3) Wire away from power lines (AC power supply wires, power lines, etc.)
(4) When an input is not being used, short V IN and I IN to the COM terminal.
(5) Use crimp terminals. (Tighten terminals to a torque of 0.5 N·m.)
(6) When using current inputs, short VIN to IIN.
(7) When there is noise in the power supply line, install a noise filter on the
input section and the power supply terminals.

Writing the Range Code
Write the range code to word n+1. A/D or D/A conversion begins when the
range code is transferred from the CPU Unit to the Analog I/O Unit. There are
eight range codes, FF00 to FF07, that combine both the analog input 1 and 2
and analog output signal ranges, as shown below.

• The Analog I/O Unit will not start converting analog I/O values until the
range code has been written.
• Once the range code has been set, it is not possible to change the setting
while power is being supplied to the CPU Unit. To change the I/O range,
turn the CPU Unit OFF then ON again.
• If a range code other than those specified in the above table is written to
n+1, the range code will not be received by the Analog I/O Unit and analog I/O conversion will not start.

• Output range of 0 to 10 V/4 to 20 mA: Bits 08 to 15
Startup Operation
After power is turned ON, it will require two cycle times plus approx. 100 ms
before the first data is converted. The following instructions can be placed at
the beginning of the program to delay reading converted data from analog
inputs until conversion is actually possible.
Analog input data will be 0000 until initial processing has been completed.
Analog output data will be 0 V or 0 mA until the range code has been written.
After the range code has been written, the analog output data will be 0 V or
4 mA if the range is 0 to 10 V, −10 to 10 V, or 4 to 20 mA.

Averaging Function for
Analog Inputs
The averaging function can be enabled for inputs using the DIP switch. The
averaging function stores the average (a moving average) of the last eight
input values as the converted value. Use this function to smooth inputs that
vary at a short interval.
Open-circuit Detection
Function for Analog
Inputs
The open-circuit detection function is activated when the input range is set to
1 to 5 V and the voltage drops below 0.8 V, or when the input range is set to 4
to 20 mA and the current drops below 3.2 mA. When the open-circuit detection function is activated, the converted data will be set to 8,000.
The time for enabling or clearing the open-circuit detection function is the
same as the time for converting the data. If the input returns to the convertible
range, the open-circuit detection is cleared automatically and the output
returns to the normal range.

Setting the Averaging Function
DIP switch pins 1-1 and 1-2 are used to set the averaging function. When
averaging is enabled, a moving average of the last eight input values is output
as the converted value. The averaging function can be set separately for analog inputs 1 and 2.

(1) Use shielded twisted-pair cables, but do not connect the shield.
(2) When an input is not being used, short the + and − terminals.
(3) Separate wiring from power lines (AC power supply lines, high-voltage
lines, etc.)
(4) When there is noise in the power supply line, install a noise filter on the
input section and the power supply terminals.

24 VDC
Example: If analog input device 2 is outputting 5 V and the same power supply is being used for both devices as shown above, approximately 1/3, or 1.6
V, will be applied to the input for input device 1.
If a wiring disconnection occurs when voltage input is being used, the situation described below will result. Either separate the power supplies for the
connected devices, or use an isolator for each input.
If the same power supply is being used by the connected devices and a disconnection occurs at points A or B in the above diagram, an unwanted circuit
path will occur as shown along the dotted line in the diagram. If that occurs, a
voltage of approximately 1/3 to 1/2 of the output voltage of the other connected device will be generated. If that voltage is generated while the setting
is for 1 to 5 V, open-circuit detection may not be possible. Also, if a disconnection occurs at point C in the diagram, the negative (-) side will be used in for
both devices and open-circuit detection will not be possible.
This problem will not occur for current inputs even if the same power supply is
used.
Note
When external power is supplied (when setting the range code), or when
there is a power interruption, pulse-form analog output of up to 1 ms may be
generated. If this causes problems with operation, take countermeasures
such as those suggested below.
• Turn ON the power supply for the CP1L CPU Unit first, and then turn ON
the power supply for the load after confirming correct operation.
• Turn OFF the power supply for the load before turning OFF the power
supply for the CP1L CPU Unit.

I/O Allocation
Two input words and one output word are allocated to the Analog I/O Unit
starting from the next word following the last allocated word on the CPU Unit
or previous Expansion Unit or Expansion I/O Unit.

Writing the Range Code
Write the range code to word n+1. A/D or D/A conversion begins when the
range code is transferred from the CPU Unit to the Analog I/O Unit. There are
five range codes, 000 to 100, that combine the analog input 1 and 2 and analog output signal ranges, as shown below.

• The Analog I/O Unit will not start converting analog I/O values until the
range code has been written. Until conversion starts, inputs will be 0000,
and 0 V or 0 mA will be output.
• After the range code has been set, 0 V or 0 mA will be output for the 0 to
10-V, −10 to 10-V, or 0 to 20-mA ranges, and 1 V or 4 mA will be output for
the 1 to 5-V and 4 to 20-mA ranges until a convertible value has been
written to the output word.
• Once the range code has been set, it is not possible to change the setting
while power is being supplied to the CPU Unit. To change the I/O range,
turn the CPU Unit OFF then ON again.
459
Section 7-4
Analog I/O Units
Reading Converted Analog Input Values
The ladder program can be used to read the memory area words where the
converted values are stored. Values are output to the next two words (m + 1,
m + 2) following the last input word (m) allocated to the CPU Unit or previous
Expansion Unit or Expansion I/O Unit.
Writing Analog Output Set Values
The ladder program can be used to write data to the memory area where the
set value is stored. The output word will be “n+1,” where “n” is the last output
word allocated to the CPU Unit or previous Expansion Unit or Expansion I/O
Unit.
Startup Operation
After power is turned ON, it will require two cycle times plus approx. 50 ms
before the first data is converted. The following instructions can be placed at
the beginning of the program to delay reading converted data from analog
inputs until conversion is actually possible.
Analog input data will be 0000 until initial processing has been completed.
Analog output data will be 0 V or 0 mA until the range code has been written.
After the range code has been written, the analog output data will be 0 V or
0 mA if the range is 0 to 10 V, −10 to 10 V, or 0 to 20 mA, or it will be 1 V or
4 mA if the range is 1 to 5 V or 4 to 20 mA.

After 0.1 to 0.2 s (100 to 200 ms), the input
for TIM 5 will turn ON, and the converted
data from analog input 0 that is stored in
word 2 will be transferred to D00000.

Handling Unit Errors
• When an error occurs in the Analog I/O Unit, analog input data will be
0000 and 0 V or 0 mA will be output as the analog output.
If a CPU error or an I/O bus error (fatal errors) occurs at the CPU Unit and
the analog output is set to 1 to 5 V or 4 to 20 mA, 0 V or 0 mA will be output. For any other fatal errors at the CPU Unit, 1 V or 4 mA will be output.
• Expansion Unit and Expansion I/O Unit errors are output to bits 0 to 6 of
word A436. The bits are allocated from A436.00 in order starting from the
Unit nearest the CPU Unit. Use these flags in the program when it is necessary to detect errors.
Programming Example
This programming example uses these ranges:
Analog input 0: 0 to 10 V
Analog input 1: 4 to 20 mA
Analog output: 0 to 10 V

• If the input temperature exceeds the range that can be converted, the
converted temperature data will be held at the maximum or minimum
value in the range.
• If the input temperature exceeds the range by more than a specified
amount, the open-circuit detection function will detect an open-circuit and
the converted temperature data will be set to 7FFF.
The open-circuit detection function will also operate if the cold junction
compensator is faulty.
• The open-circuit detection function will be automatically cleared and normal input temperature conversion will begin automatically when the input
temperature returns to the convertible range.

Startup Operation
After power is turned ON, approximately 1 s is required for the first conversion
data to be stored in the input word. During that period, the data will be 7FFE.
Therefore, create a program as shown below, so that when operation begins
simultaneously with startup it will wait for valid conversion data.

Handling Unit Errors
• Expansion Unit and Expansion I/O Unit errors are output to bits 0 to 6 of
word A436. The bits are allocated from A436.00 in order starting from the
Unit nearest the CPU Unit. CP1W-/CPM1A-TS002 and CP1W-/CPM1ATS102 Temperature Sensor Units are allocated two bits each. Use these
flags in the program when it is necessary to detect Expansion Unit/Expansion I/O Unit errors.
• When an error occurs, the Temperature Sensor Unit data becomes 7FFF
hex (the same as for an open-circuit detection). With an open-circuit
detection, it is not reflected in word A436.

Two-decimal-place
Mode
Note
If pin 2 on the DIP switch is turned ON, values are stored to two decimal
places. In this case, temperature data is stored as 6-digit signed hexadecimal
(binary) data with 4 digits in the integer portion and 2 digits after the decimal
point. The actual data stored in memory is 100 times the actual value, i.e., the
decimal point is not indicated. Methods for handling this data are described in
this section.
When set to store values to two decimal places, temperature data as far as
two digits after the decimal point is converted to 6-digit binary data, but the
actual resolution is not 0.01°C (°F). For this reason, there may be skipping
and inaccuracies in the first digit after the decimal point (0.1). Treat any resolution above that specified for the normal data format as reference data.

I/O Allocation
I/O words are allocated to the CompoBus/S I/O Link Unit in the same way as
to other Expansion Units and Expansion I/O Units, i.e., the next available input
and output words are allocated. As shown below, when “m” is the last allocated input word and “n” is the last allocated output word, the CompoBus/S I/
O Link Unit is allocated “m+1” as its input word and “n+1” as its output word.

Note
(1) The 8 bits of I/O data are not always transmitted simultaneously. In other
words, 8 bits of data transmitted from the Master CPU Unit at the same
time will not always reach the Slave CPU Unit simultaneously, and 8 bits
of data transmitted from the Slave CPU Unit at the same time will not always reach the Master CPU Unit simultaneously.
When the 8 bits of input data must be read together, modify the ladder
program in the CPU Unit receiving the data. For example, read the input
data twice in succession and accept the data only when the two values
match.
(2) Unused bits in the CompoBus/S I/O Link Unit’s output word can be used
as work bits, but unused bits in the output slaves cannot be used as work
bits.
(3) Unused bits in input word cannot be used as work bits.
Determining the Node
Number and Making DIP
Switch Settings
Node Number
• The CompoBus/S I/O Link Unit is a Slave Unit with 8 input bits and 8 output bits. The node number setting is made using the DIP switch; the
inputs and outputs share the same node number.
• The range of possible node number settings is determined by the type of
PLC the Master Unit is mounted to and the settings on the Master Unit.
For details refer to the CompoBus/S Operation Manual.

Handling Unit Errors
484
If a communications error occurs while the slave is on standby, the appropriate bit in word A436 will turn ON. The appropriate bit is determined by the
order in which the Expansion Units and Expansion I/O Units are connected.
The Unit nearest to the CPU Unit uses A436.00. Use these flags in the program when it is necessary to detect errors.

(1) The 32 bits each of I/O data are not always transmitted simultaneously.
In other words, 32 bits of data transmitted from the Master CPU Unit at

and 32 bits of data transmitted from the CP1L CPU Unit at the same time
will not always reach the Master CPU Unit simultaneously.
When the 32 bits of input data must be read together, modify the ladder
program in the CPU Unit receiving the data. For example, read the input
data twice in succession and accept the data only when the two values
match.
(2) Unused bits in the DeviceNet I/O Link Unit’s output words can be used as
work bits if they are not used for output from the slave.
(3) Unused bits in input words cannot be used as work bits.
