1.2Features
(1) Flexible system configuration
The employed connection block type provides the combined use of a main module and an extension module.
A flexible configuration can be achieved because various extension modules can be connected.
In addition, the main module always monitors the connection status of the extension module, leading to an early
detection of connection failure.
Various extension modules can be
connected according to the application.
No wiring of wires and Ethernet cables
is required.

Extension A/D converter module
Extension D/A converter module
(2) Easy setting of station numbers
Station numbers are set with the rotary switch on the front of the module, where setting and checking the station
numbers are easy.
(3) Selectable conversion speed
A/D conversion at 100μs/channel meets the need of a high-speed conversion.
Under the environment in which noise is likely to occur, switching the conversion speed to 400μs/channel or
1ms/channel minimizes the effect of noise on the digital operation value, the stability of which is improved.
16
CHAPTER 1 A/D CONVERTER MODULE
(4) A/D conversion at any desired timing
A/D conversion is performed once immediately after the input of a trigger conversion request to obtain the digital
operation value.
The combination with the external signal assignment function allows direct input of a trigger conversion request
from the extension input module, with the following advantages:
• Being free from the effect of the sequence scan and link scan, digital operation values can be constantly
obtained at a given timing, which leads to the improvement of the reliability.
• Digital operation values can be obtained without any program, which leads to a reduction in the cost of
creating a program.

Main A/D converter module
Trigger conversion request by the external
signal assignment function
(5) Change to any scale
A/D conversion values can be converted to be within any scale, the range of which is determined arbitrarily.
According to the device that handles digital operation values, the scale can be changed without any program,
resulting in cost reduction.
(6) Detection of the disconnection
An input range of 1 to 5V, or 4 to 20mA allows the detection of the disconnection of analog input, facilitating the
diagnosis of the cause at the time of a trouble.
In combination with the external signal assignment function, the extension output module allows a signal (input
signal error detection signal) to be output to the outside without any program upon detection of the disconnection.
At this time, there is no influence of the sequence scan and link scan.

occurred.
An error signal occurred in the A/D
converter module can be output to the
extension output module directly.
Error lamp
(external device)
Programming is not necessary to
turn on an error lamp when an error
occurs.
Using the external signal assignment function allows a trigger conversion request to be input from the extension
input module. In the event of an error or an alert, an error status or an alert status can be output from the
extension output module.
These input and output are not affected by the sequence scan and link scan.
To turn on the lamp when an error occurs.
(8) Support for the CC-Link IE Field Network synchronous communication
function
A/D conversion can be performed together with the synchronization period of the master station that supports the
CC-Link IE Field Network synchronous communication function.
This enables the A/D converter module to operate at the same timing of other slave stations sharing the same
The module can be installed in six directions using a DIN rail.

(10)Easy module replacement
The terminal block for module power supply and FG, and the terminal block for analog input signals have a two-
piece structure, where the module can be replaced with the wire connected. In addition, the terminal block for
analog input signals has a lift-up structure, where the terminal block lifts only by loosening the terminal block
mounting screw, enabling it to be removed easily.
(11)Check on the error history
The history of the last 15 errors and occurrence time is stored in the main A/D converter module.
Checking the error information of the past helps to identify the cause at the time of a trouble.
(12)Easy settings by CC IE Field configuration of the engineering tool
The CC IE Field configuration of the engineering tool makes it possible to set parameters on its window, thereby
reducing the programs. In addition, the setting status and the operating status of modules can be checked easily.

at every sampling period and averages these values,
storing the averaged value into the remote register.
The target range for average processing moves at
each sampling, thereby allowing the latest digital
operation value to be obtained.
Allows the input range to be selected for each channel
from the following:
• Factory default range (4 to 20mA, 0 to 20mA, 1 to
5V, 0 to 5V, -10 to 10V)
• User range (user range setting 1, user range setting
2)
For each channel, stores the maximum and minimum
values of digital operation values into the remote
buffer memory.
Outputs an alert when a digital operation value falls
within the alert output range set in advance.

within the range of the scaling upper limit value and
the scaling lower limit value, both of which are set at
desired values.
Adds the conversion value shift amount specified to a
digital operation value and stores it into the remote
register. This function facilitates fine adjustment at the
system start-up.
Allows the maximum value and the minimum value of
a digital output value to be fixed at 16000 and 0 or 16000 respectively if a voltage or current exceeding
the input range is input.

(1) Parameter area (address: 0000H to 04FFH)
For the parameter area, parameters can be set by means of the CC IE Field configuration of the engineering tool,
or the REMTO instruction.
The parameters in the parameter area are backed up to the non-volatile memory.
The parameters backed up to the non-volatile memory are read out to the parameter area when the module
power supply is turned off and on or the module is reset by remote reset.
For the parameters written from the parameter settings of the CC IE Field configuration of the engineering tool,
the write to the non-volatile memory is also completed at the same time. For the parameters written using the
REMTO instruction, the timing of the write to the non-volatile memory is at the time of turning on Initial data
setting request flag (RY9) from off. At this time, even an invalid parameter is written to the non-volatile memory as
well. With an invalid parameter written, turning off and on the power supply causes the invalid parameter to be
read from the non-volatile memory, resulting in the error code being stored into Latest error code (RWr0). Take
corrective action with reference to the error code list. ( Page 172, Section 11.2)

When the latest profile of the A/D converter module is necessary, please consult your local Mitsubishi representative.
The profile is a setting file that stores information required for the start-up, operation, and maintenance of devices supporting
the CC-Link family. A module is added to "Module List" of "CC IE Field Configuration" window by profile registration to GX
Works2 or GX Works3. For the profile registration, refer to the following.
This chapter describes the installation and wiring of the A/D converter module.
6.1Station Number Setting
(1) Setting method
Set the station number with the rotary switch on the front of the module. Set the station number in the power-off
state because the set value is enabled at power-on.
• The dial x10 is used to set the hundreds and tens place of a station number.
• The dial x1 is used to set the ones place of a station number.
For the station number 115, set the switch as shown below.
(2) Setting range
Set the station number, which can be from 1 to 120. A value other than 1 to 120 causes a communication error,
resulting in the D LINK LED flashing.
● While the module power supply is in an on state, changing the station number setting switch causes a minor error,
resulting in the ERR. LED flashing.
When the station number setting switch is set back to the previous state, the module recovers from the error after five
seconds, resulting in the ERR. LED turning off.
● For the station number setting, avoid duplication with the other station numbers. Number duplication causes a
communication error, which does not allow the D LINK LED to light up.

CHAPTER 6 INSTALLATION AND WIRING
(c) Precautions for external wiring
To obtain the maximum performance from the functions of the A/D converter module and improve the system
reliability, an external wiring with high durability against noise is required. Precautions for external wiring are as
follows:
• Use separate cables for the AC control circuit and the external input signals of the A/D converter module to
avoid the influence of the AC side surges or induction.
• Do not install cables together with the main circuit lines, high voltage lines, or power cables for equipment
other than the programmable controller. Noise, surges, or induction may affect the system.
• Ground the shielded wires or shielded cables at one point on the programmable controller side. However,
depending on the external noise conditions, it may be better to ground them externally.
• For the voltage input, do not exceed a range of ±15V. Doing so can cause breakdown of the elements.
• For the current input, do not exceed a range of ±30mA. Doing so can cause breakdown of the elements.

CHAPTER 7 VARIOUS SETTINGS
Remark
CHAPTER 7VARIOUS SETTINGS
This chapter describes how to set up various settings of the A/D converter module.
7.1Parameter Settings
Set the parameter of this module with the network parameter written to the CPU module of the master station. For the
setting procedure of the master station, refer to the following:
User's manual for the master/local module used
● Place a checkmark in the "Set the network configuration settings in CC IE Field configuration window" box on the
"MELSECNET/CC IE/Ethernet Module Configuration" window in advance.
● To select the main A/D converter module in the CC IE Field Configuration window, select "NZ2GF2B-60AD4" from the
"Module List" window.
● To select an extension module in the "CC IE Field Configuration" window, select the following models from the "Module
List" window.
Extension module typeName
Extension Digital Input ModuleNZ2EX-16 (DI)
Extension Digital Output ModuleNZ2EX-16 (DO)
Extension A/D Converter ModuleNZ2EX2B-60AD4
Extension D/A Converter ModuleNZ2EX2B-60DA4
● Setting fewer points of the remote I/O signal or remote register than actual points that the main A/D converter module or
the extension module possesses does not cause an error. In this case, data of all the set points are subject to cyclic
transmission in order.

7.1 Parameter Settings
69
(1) Precautions
Do not uncheck the box.
(a) Before parameter settings
For the precautions before parameter settings, refer to the following.
• When using the A/D converter module, always enable the block data assurance per station. When it is
disabled, correct operation of the A/D converter module cannot be guaranteed. For details on the block
data assurance per station, refer to the following: User's manual for the master/local module used.
• Do not set the parameters using the CCPASET instruction in the master station. Executing the CCPASET
instruction results in the module operating with block data assurance per station deactivated, where proper
performance as the A/D converter module cannot be guaranteed. (The CCPASET instruction is intended
to configure parameters for a master/local module. For details on the CCPASET instruction, refer to the
following: User's manual for the master/local module used.)
• When using an extension module, be sure to write the module parameters ( Page 71, Section 7.1 (2)).
If the parameters of the extension module has not been written, the error code (1F30H) is stored in Latest
error code (RWr0), Error flag (RXA) turns on, and the ERR. LED lights up.

● Set up the offset value and the gain value under actual use conditions.
Connection to the CC-Link IE Field Network is not necessary.
● Set up the offset/gain setting in the range satisfying the following condition. If the range is exceeded, the maximum
resolution and accuracy may not fall within the range described in the performance specifications.
● Set values are held and available even after turning off the module power supply because a offset value and a gain value
are written into the non-volatile memory in the main A/D converter module.
● Set up the offset/gain setting so that the offset value is smaller than the gain value.
With Range setting (address: 0103H) set to User range setting 1 or User range setting 2, the main A/D converter module
performs a check on the offset/gain set values when Initial data setting request flag (RY9) is turned on from off. For
invalid condition (offset value ≥ gain value), this check results in the error code (040H) being stored into Latest error
code (RWr0), Error flag (RXA) turning on, and the ERR. LED lighting up.
● The extension A/D converter module does not support user range. Therefore, the offset/gain setting cannot be set up for
the extension A/D converter module.

Conversion speed is the rate at which an A/D converter module converts analog input values.
A sampling period is the period of conversion processing within the one channel.
A conversion period is the period of the update of a digital operation value with the A/D conversion method (sampling
processing or averaging processing) taken into account, and is equivalent to an integral multiple of the sampling
period. ( Page 95, Section 8.6)
The following figure shows the relationship between conversion speed and a sampling period.
The sampling cycle varies depending on the type of main analog module, the conversion speed, the type of extension
module, and the number of conversion enabled channels.
The following table shows the classification.

(1) Sampling processing
This processing performs A/D conversion on analog input values in sequence. The converted values at this time
are referred to as digital operation values.
For a main A/D converter module, digital operation values are stored into CH Digital operation value (RWr2 to
RWr5) at every sampling periods. For an extension A/D converter module, digital operation values are stored into
CH Digital operation value (RWr12 to RWr15) at every sampling periods.
The sampling period of the main A/D converter module and the extension A/D converter module depends on the
conversion speed setting and the number of conversion enabled channels. For details, refer to the following:
• Conversion Speed and Sampling Period ( Page 90, Section 8.5.1)
(2) Averaging processing
This processing performs averaging processing on digital operation values for each channel, storing the average
values into CH Digital operation value (RWr2 to RWr5, RWr12 to RWr15).
There are three types of averaging processing as follows:

The number of processing times varies depending on the sampling period.
The number of processing times assuming the following settings with no extension module connected

For the time average, the valid lower limit value to be set is given by: Minimum number of processing times, or
4 × Sampling period.

period.
Example: A maximum of 4 channels is used (conversion speed: 1ms/channel)
(1ms × 4) × 4 = 16ms
If the number of processing times falls below four due to the set time, an error occurs (error code: 020), where the digital
operation value becomes 0.
(b) Count average
This processing performs A/D conversion for a set number of times and averages the total excluding the
maximum and minimum values, storing the average value into CH Digital operation value (RWr2 to RWr5,
RWr12 to RWr15).
The time taken to store the average value obtained by count average into CH Digital operation value (RWr2
to RWr5, RWr12 to RWr15) varies depending on the sampling period.
Number of processing times = Set number of times × Sampling period
Processing times assuming the following settings with no extension module connected:
ItemSetting
Number of channels used (number of channels where A/D conversion is enabled)4 channels (CH1 to CH4)
Conversion speed400μs/channel
Set number of times20 times
20 × (4 × 0.4) = 32.0 (ms)
→ An average value is output every 32.0 ms.
Because the count average requires a sum of at least two counts except the maximum and minimum values, the set number
of times should be set to four or more.

(c) Moving average
This processing averages the digital output values taken in at each sampling cycle for a specified number of
times, storing the average value into CH Digital operation value (RWr2 to RWr5, RWr12 to RWr15).
Because the averaging processing is performed on a moving set of sampling processing, the latest digital
operation values can be obtained.
The moving average processing for a set number of times of four is shown below:
