4.- INTERCONNECTING MODULES
The MULTIFIT unit system can be used to interconnect various modules. Modules do not have to be
connected in a specific order. In any case, CIRCUTOR supplies two factory configurations:
1. M-BASE + M-QNA500
2. M-BASE + M-QNA500 + M-8IO
The MULTIFIT internal communications system allows each module to operate independently (Master
mode), so that each module can take its own decisions, regardless of the type of c onnection.
Modules are interconnected with a communications connector (26 PINS) located on the side of each
module. Once all modules have been installed, it is advisable to close the side connector of the last
module with the cover supplied with the equipment. The M-BASE can only power a specific number of
modules, due to the consumption of each one. The maximum capacity of each M-BASE module can be
used to power 2 QNA500 systems and 2 M-8IO or 4 M-8IO systems.

6.- OPERATION OF THE QNA500 (MULTIFIT SYSTEM DESCRIPTION)
6.1.- Physical description
The QNA500 is a top performance power quality analyzer that is part of a new generation of products the MULTIFIT range. This innovative system can be used to add various modules to expand the
performance of the system while controlling the global electrical installation.
The QNA500 is com posed of an M-BASE power supply and communications module that can power
the set of modules and intercommunicate them through its internal bus. This optimises the installation,
since various modules can be connected in parallel to a single M-BASE b ase module. In addition, this
module can communicate with any other module via its RS-232, RS-485 or ETHERNET ports.
Likewise, the QNA500 can take electrical voltage (5 independent channels) and current measurements
(5 independent channels) to supervise the installation and to detect existing anomalies, with the
purpose of analysing it and carrying out predictive maintenance.
6.1.1.- BASE MODULE (M-BASE)
M-BASE is the main module of the MULTIFIT system. This module is vital in any combination with the
systems of the MULTIFIT range, since it is responsible for powering all other modules and establishing
the communications with external devices.
M-BASE has 3 communications ports that can communicate the information of the connected modules
to external devices and systems. The ports are as follows:
• RS-232
• RS-485
• ETHERNET (TCP/IP)
The 3 communications ports operate as independent systems. In other words, they can simultaneously
request information from all connected modules. M-BASE module has a series of LED indicators that
are used to show the correct operation of the power supply and communication systems.

7.- BASE MODULE SETUP (M-BASE)
The QNA500 analyzer can be configured with the software supplied by CIRCUTOR, using the
analyzer's WEB server or editing the Setup.XML file.
This file can be edited with non-proprietary software and can configure the analyzer, in accordance with
the installation's requirements.
The M-BASE module has been designed to power all other MULTIFIT modules connected to it,
establish communications with external devices via any of the 3 communications ports (RS-232, RS485 or ETHERNET) and act as an external and internal communications switch.
We recommend using an ETHERNET cable to configure the M-BASE module. Connect to the WEB
server hosted in this module with a PC f or such procedures. You can easily and quickly configure the
module in a few seconds.
(*) Refer to the corresponding software manual for more information related to the configuration of the
analyzer with the use of CIRCUTOR software.
(**) R efer to t he specific section in this manual for more information related to the configuration of the
analyzer with the use of the WEB Server.
7.1.- COMMUNICATIONS
We recommend using the WEB server or software provided by CIRCUTOR to access the
communications setup menu of the M-BASE.
When using the Ethernet port, QNA500 8IO is configured with the DHCP option enabled. When it is
connected to an intranet with a DHCP server, the server will automatically assign an IP address to the
analyzer.
Use the IP Setup software supplied with the analyzer to know t he IP address assigned by the server or
assign a specific IP address. To do so, it is vital to know the MAC address shown on the silver
adhesive label attached to the top of the product.
The QNA500 analyzer's default configuration is as follows:
• (M-BASE): Peripheral no., speed - length - parity - stop bits: 1, 9600-8-N-1
• (QNA500 8IO): Peripheral no., speed - length - parity - stop bits: 2, 9600-8-N-1
The default configuration of the input-output module (M-8IO and M-8IOR) is as follows:
• (M-8IO): Peripheral no., speed - length - parity - stop bits: 10, 9600-8-N-1
• (M-8IOR): Peripheral no., speed - length - parity - stop bits: 10, 9600-8-N-1
All communications ports are MULTI-PROTOCOL, so that the port can communicate with all protocols
supported by the MULTIFIT system.
Available protocols:
QNA500 8IO Instruction manual
26 / 111
POWER QUALITY ANALYZER QNA500 8IO
• MODBUT/RTU (on-line communications)
• MODBUS/TCP (on-line communications)
• CIRBUS (on -line communications of the question-answer type in the ASCII format)
• ZMODEM (partial or complete file download)
• HTTP (web protocol)
• FTP (complete file download)
The previous figure shows how the WEB server of the M-BASE module can be used to program its I P
address and configure the RS-232 and RS-485 ports.
7.1.1.- IP ADDRESS CONFIGURATION
Once the equipment has been installed in an IT network with a DHCP server, the server will
automatically assign an IP address to each MULTIFIT module. The IP address of each module must be
known to communicate with them or integrate them in an IT application.
To do so, CIRCUTOR supplies the IPSetup application, which can be used to assign a specific IP
address to each MULTIFIT module.
It is vital to know the MAC address shown on the silver adhesive label attached to the top of the
product before programming this IP address.

7.1.1.- IGMP CONFIGUARTION
IGMP default address is 225.0.10.10.
This address allows to each module to detect others and to communicate between them. To allow
management actions and communications between modules is mandatory that all MULTIFIT modules
have same IGMP address.
User must take care of following requirements:
• All modules must have same IGMP IP address
• IGMP range is from 224.0.0.0 to 239.255.255.255
• If two modules have different IGMP IP addresses, they don’t detect each other and they cannot
send messages between them.
• If exists Ethernet switches in the LAN, these cannot have activated multicast message filters
Some industrial switch are provided with IGMP message filters. Keep in mind that if this
switches are activated, QNA500 won’t be able to send messages between modules.

POWER QUALITY ANALYZER QNA500 8IO
7.1.2.- NTP SYNCHRONIZATION
NTP synchronization allows to QNA500 modules to synchronize its clocks with milliseconds of
resolution.
This synchronization allows that many devices works with the same date and time, avoiding errors with
different time flags in data.
M-BASE is able to synchronize all modules connected to itself by activating this option. You can set up
to 2 different NTP servers, a primary server and an auxiliary server.
To configure NTP synchronization is mandatory to set-up following fields:
NTP IP: IP address of the NTP server.
NTP Port: port number of the NTP server.
Additionally, you can check if communication is working properly using ‘Get Time’. If communication is
working properly, you will see UTC Time. If not, you will see 00/00/00 00:00:00.
7.1.3.- DEVICE NUMBER CONFIGURATION
MULTIFIT system allows to assign a device number to each module and an IP address. Device
number must be unique in the bus and cannot be repeated by any-other MULTIFIT module or a device
in the RS485 connected to a M-BASE. If this happens, modules will detect a repeated device number
an communications won’t work correctly.
M-BASE works as a GATEWAY of other devices connected to the RS-485 port (i.e. power analyzers
CVM). It’s very important to check that these devices have different device number of the MULTIFIT
modules.

8.- POWER QUALITY ANALYZER SETUP (M-QNA500)
The QNA500 power quality analyzer can measure the voltages and currents of the electrical
installation, with the purpose of achieving the global supervision and control of the whole installation.
The following sections describe the main configuration options and the configuration options.
8.1.- COMMUNICATIONS
To access to the setup it’s recommendable to use WEB-Server or software provided by CIRCUTOR.
In case of using ETHERNET port, QNA500 is setup with DHCP as default, so if this is connected to a
LAN network, DHCP server of this LAN will provide IP addresses to each module automatically.
To know assigned IP address, or to assign an specific IP address, you can use IP setup software,
which ask you MAC address and allows you to set an specific IP to each module.
By default, QNA500 has following configuration:
• (QNA500): Device Number, Baud Rate, Length, Parity, Stop Bits: 2, 9600-8-N-1
All communication ports are MULTIPROTOCOL which means that you can communicate using any of
the supported protocols.
Available protocols are the following:
• MODBUS/RTU (on-line communications)
• MODBUS/TCP (on-line communications)
• CIRBUS (on-line communications)
• ZMODEM (protocol to download files)
• FTP (protocol to download files)
• HTTP (protocol to connect using Web-Browser)
8.2.- MEASUREMENT
The following measurement parameters can be configured:
TRANSFORMATION RATIOS:
• Voltage Primary / Voltage Secondary: It will be programmed in accordance with the voltage
transformer ratio used to take the measurement. Direct measurements must be programmed to
1/1. This ratio must not exceed 9999. Maximum primary and secondary values are 500000 and
999,9 respectively.
• Current primary: The current transformer primary used to measure the current will be
programmed. Maximum primar y value is 10000.
• Current secondary: The current transformer secondary used to measure the current will be
programmed (default: 5 A).
QNA500 8IO Instruction manual
30 / 111
POWER QUALITY ANALYZER QNA500 8IO
• Neutral Current Primary: The current transformer primary used to measure the neutral current
will be programmed.
• Primary VT * Primary CT ratios: Maximum primary value of VT multiplied by primary
value of CT must be lower than 2000000000
NOMIN AL VALUES
• Nominal Voltage: Corresponds to the nominal voltage measured by the power quality analyzer.
In the ca se of t he 3-wire configuration, the phase-phase voltage must be programmed (e.g. 400
V), and the phase-neutral voltage must be programmed for 4-wire configurations (e.g. 230 V).
When the measurement is recorded through the voltage transformers, the nominal voltage must
be programmed so that it is referred to the secondary (e.g. 63.5 V). This value is vital for the
correct recording of events.
• Nominal Current: Corresponds to the nominal current being measured by the analyzer, which
will be used to establish the maximum and minimum % to record disturbances. The default
value is 5 A. The value used to program measuring transformers is recommended.
• Nominal Frequency: Nominal frequency of the network being analyzed. This parameter is
required to calculate the effective value of the signal in top quality networks.
TYPE OF CONNECTION
• 3-wire / 4-wire: QNA500 8IO is prepared for an operation in installations with a neutral (4-
wires) or installations without a neutral (3-wires). The type of connection is defined at this point.
This is important, since the value programmed for this variable will be used to detect and record
voltage events. When programmed for 4-wires, all measurements will be taken from phaseneutral, and when programmed for 3-wires, the reference values will be phase-phase.
MEASURING POINT
• Description: This field is only used for identification purposes by the user.
• Comments: This field is only used for information purposes by the user.
QNA500 8IO Instruction manual
31 / 111
POWER QUALITY ANALYZER QNA500 8IO
8.3.- POWER QUALITY
The voltage levels must be defined to calculate the power quality events.
• % Overvoltage threshold: Overvoltage detection depends on the value programmed in this
section. Any semi-cycle with an RMS value that exceeds this threshold (% over the nominal
voltage) will be understood as an overvoltage. The events file (EVQ) will save a record when
this value is exceeded, stating the phase, maximum voltage recorded, mean voltage, voltage
before the event occurred and the time during which this threshold has been exceeded.
• Overvoltage hysteresis: An overvoltage hysteresis will be defined so that the event start
voltage is not the same as the event end voltage. Therefore, an overvoltage starts when the
semi-cycle voltage exceeds the overvoltage threshold and ends when it goes below the said
threshold + the hysteresis programmed for this threshold.
• % Sag threshold: Sag detection depends on the value programmed in this section. Any semi-
cycle with an effective value that does not reach this threshold (% over the nominal voltage) will
be understood as a sag. The events file (EVQ) will save a record each time this value is not
exceeded, stating the minimum voltage recorded, mean voltage and the time during which this
threshold was not exceeded.
• Sag hysteresis: A sag hysteresis will be defin ed so tha t the s ag start vo ltage is n ot the same
as the sag end voltage. Therefore, a sag is started when the voltage does not exceed the sag
threshold and it ends when this threshold is exceeded + the hysteresis programmed for this
threshold.
• % Interruption threshold: Interruption detection depends on the value programmed in this
section. Any semi-cycle with an effective value that does not reach this threshold (% over the
nominal voltage) will be understood as an interruption. The events file (EVQ) will save a record
each time this value is not exceeded, stating the minimum voltage recorded, mean voltage and
the time during which this threshold was not exceeded.
• Interruption hysteresis: An interruption hysteresis will be defined so that the interruption start
voltage is not the same as the interruption end voltage. Therefore, an interruption is started
when the voltage does not exceed the interruption threshold and it ends when this threshold is
exceeded + the hysteresis programmed for this threshold.
8.4.- TRANSIENTS
QNA500 can detect transients, according to different conditions. Transients can be detected in
accordance with 2 different conditions:
The following variables must be configured to record the transients:
1. Semi-cycle RMS value: RMS value of each cycle is calculated, updated each semi-cycle, and
compared with the maximum and minimum values programmed by the user. When the
maximum or minimum RMS value is exceeded, this is considered the moment when a tr ansient
or disturbance is set off. We advise setting the maximum or minimum values far from the
nominal value existing in the installation. Otherwise, the analyzer will record many different
transients that will not be relevant in a future user analysis.
QNA500 8IO Instruction manual
32 / 111
POWER QUALITY ANALYZER QNA500 8IO
2. dV/dt detection (ramp met hod): This detection is achieved by comparing the measured wave
shape with an ideal wave shape. Each one of the 512 samples is compared to the previous
sample; when this value exceeds the value of the maximum ramp calculated for each point, the
system will consider that a transient or disturbance has been generated, depending on the
sensitivity selected by the user. The maximum ramp is the tangent calculated for each point of
the sine wave.
Rm = Vp * w/oϕ * trigger level
The following variables must be configured to record the wave shape:
• Nº pre-trigger cycles: Number of cycles registered before activating the record (1 to 10.
Default: 5)
• Nº. post-trigger cycles: Number of cycles registered after activating the record (1 to 50.
Default: 15)
• Trigger level (maximum ramp detection): Value that determines the transient detection
sensitivity level. Th e value entered must be from 1 to 100.
When the sensitivity value entered is very low, the analyzer will be very sensitive when
detecting transients. On the other hand, when the sensitivity value entered is very high, the
deformation of the signal must be greater for the analyzer to start detecting it.
• Maximum and minimum effective comparison values (RMS system): A maximum and
minimum voltage / current percentage must be programmed, when compared to the nominal
value.
The trigger is activated when the effective value of a cycle updated each semi-cycle exceeds
the maximum value or is under the minimum programmed value.
• Trigger variables: Variable or variables that will trip the trigger, in accordance with the
conditions described above. The trigger is activated by the f irst programmed variable that meets
the conditions when more than one variable is programmed.
The transient will be recorded in the COMTRADE format (according IEEE C37.111) and the data will
be saved in the WAVE directory of the memor y. The waveform of the 4 voltage and current channels
(P1, P2, P3, N) will be stored for each disturbance detected. The memory record is stored at 204
samples per cycle.
The date of the last disturbance detected can be checked to guarantee the correct configuration of the
transient setup, adjusting the most adequate sensitivity degree for the installation.
The same configuration can be easily and quickly saved with CIRCUTOR's PC software.
8.5.- REMOVE FILES
Records can be deleted from the MULTIFIT system through the WEB server or the software supplied
by CIRCUTOR.
Refer to the specific section in this manual for more information about deleting records via the WEB
server. This action deletes all files associated to the measurements taken by the analyzer.
QNA500 8IO Instruction manual
33 / 111
POWER QUALITY ANALYZER QNA500 8IO
8.6.- CLOCK
Make sure that the correct time has been pr ogrammed before the analyzer's programming pr ocedures
have been completed. Use the analyzer's WEB server (see corresponding section) or the specific
CIRCUTOR software to make sure that the correct time has been programmed in the analyzer.
QNA500 offers the Local Time or UTC Time options.
8.7.- BATTERY
M-BASE module has an internal battery that can be used to power all connect ed modules. The m ain
purpose of this battery is to make sure that all modules continue to operate during a limited period of
time in case there is an interruption in the electric supply.
The most common function entails storing voltage sags or interruptions, and moreover keep active the
communication with the device or perform certain operations (activate/deactivate loads).
The main feature of the product s of t he MULTIFIT range is based on the connection of said products to
the same M-BASE module, which will operate as independent products. The battery can power the
modules connected to the system during a period of time configured by the user. The default time is 1
minute and it can be configured to up to 15 minutes. The M-BASE module can power a maximum of 2
QNA500 modules + 1 M-8IO module simultaneously with the battery.
8.8.- STANDARD RECORDING PERIOD
The recording period shows the number of minut es that QNA500 8IO uses to create a new register in
the memory. All electrical parameters will be recorded (only those selected) at the end of the
programmed time. Average, maximum and minimum values obtained during this period of time will be
recorded. The default recording time is 10 minutes. This value can be modified to a period of between
1 minute and 2 hours. This time only affects the data file (.STD).
8.9.- ENERGY RECORDING PERIOD
The recording period shows the number of minutes that QNA500 8IO uses to create a new register with
energy values in the memory.
8.10.- SELECTING VARIABLES TO BE RECORDED
QNA500 analyzer can be used to select the variables that will be recorded. These variables can be
selected via the WEB server (see the corresponding section in this manual) or via specif ic CIRCUTOR
software.

QNA500 analyzer will record all variables selected every X minutes once the variables have been
selected and the new configuration has been sent, in accordance with the programmed standard
recording time period.
These records are saved in various files, depending on the type of data. Refer to the file section for
more information related to the location of these information records.
8.11.- ALARM SETUP (Digital objects)
QNA500 power q uality analyzer can configure a list of alarms (up to 16 alarms) for an improved and
more accurate supervision of the electrical installation and its status.
These alarms can be simply recorded in the memory or used to create actions in other MULTIFIT
modules, such as, for example, the activation of the relay of a M-8IO module.
There are 2 different types of alarms (or digital objects), as described:
• ALARM OBJECTS: can enable any alarm condition associated to an electrical variable
measured by the QNA500 module.
• ENERGY OBJECTS: these are necessary when associating a pulse output of a M-8IO module.
The most common application is where the pulse outputs can produce pulses proportional to
the energy (A+, A-, Q1, Q2, Q3 or Q4) measured by the QNA500. To do so, first activate an
energy object and activate the pulse output on the M-8IO module. This configuration is
explained in the corresponding chapter of this module.
These alarms (or digital objects) can be associated with the following variables:

The following additional conditions can be assigned to each variable:
When this instruction is sent, the analyzer will delete the current data file and the
existing configuration will be lost. You must make sure that this process is going to be
• Maximum Value
• Minimum Value
• Activation Delay (in seconds)
• Deactivation Delay (in seconds)
• Memory record (Yes/No)
• Mail Group (no, group 1, …, group 4)
Once all desired alarms have been configured, the QNA500 8IO network power quality analyzer will
permanently monitor whether the conditions of one of the programmed alarms are met or not. If this is
the case, it will generate a memory record (if programmed as such), indicating the date when the alarm
was triggered.
In addition, in case the user considers that it is important to send the notification of the alarm detected
in a different MULTIFIT module, this option can be used to perform actions on the installation, such as,
for example, closing a relay for signalling purposes.

8.13.- RECORDING FILES
QNA500 power quality analyzer records different files, in accordance with the type of data (voltage,
events, energy, etc).
The power quality analyzer records the following files:
8.13.1.- .STD FILE
The Standard File (STD) is used to store all parameters that are stored periodically.
The records will be stored with the following electrical parameters (depending on the selection),
respecting the recording period programmed with the analyzer:
maximum, minimum)

The variable recording period can be configured by the user.
FLICKER:
• Pst: QNA500 analyzer will record the Flicker value (Pst) obtained during the recording period.
The Plt value is calculated with the PC's analysis software Flicker is defined as t he variation of
the RMS value or amplitude of the voltage within a range of less than 10% of the nominal value.
This variation in voltage amplitude produces a fluctuation of the luminous flux in lamps, at the
same time inducing a sensation of visual instability (visual flashing effect).
HARMONICS:
• Harmonic Distortion: QNA500 anal yzer measures, calculates and records the mean harmonic
distortion of the voltage and current detected from the analyzed network.
• Individual Harmonics: QNA500 analyzer measures, calculates and records the mean value of
the individual harmonic distortion rate of each voltage and current harmonic from the analyzed
network (up to the 40th harmonic). (Breakdown of each 10-cycle block integrated in a recording
period).
INTERHARMONICS:
QNA500 measure and register voltage and current interhamornics. These are signals introduced in the
power cable with frequencies non-multiple of the fundamental frequency (50 or 60Hz). QNA500 is able
to measure up to interharmonic 50, corresponding to signals with frequency of 2525Hz.
UNBALANCE:
• Voltage unbalance coefficient (Kd): homopolar and direct voltage ratio.
• Voltage asymmetry coefficient (Ka): inverse and direct voltage ratio.
QNA500 8IO Instruction manual
39 / 111
POWER QUALITY ANALYZER QNA500 8IO
• Current asymmetry coefficient (Kd): homopolar and direct current ratio.
• Current unbalance coefficient (Ka): inverse and direct current ratio.
K FACTOR:
K Factor is a transformer power reduction factor. The losses generated by harmonics are taken into
account when calculating the K Factor.
It is always higher than the unit in installations with non-linear loads.
e: represents the transformer's copper loss and iron loss ratio. This value can be obtained from the
transformer test data or, alternatively, an approximate value of 0.3 can be used.
q: exponent with a value between 1.7 and 1.8.
CREST FACTOR:
The Crest Factor is equal to the amplitude of the wave shape peak divided by the RMS value. The
crest factor is calculated to provide the analyst with a quick idea of the impact on the wave shape. The
impact is constantly associated with the wear of the roller bearing, cavitation and wear of the gear
cogs, etc.
The crest factor is an important measurement associated to the status of the machine and it analyses
the wave shape, which would not be visible with the calculation of the harmonic distortion rate alone.

It is a perfect sine wave, with a "1" amplitude", RMS value equal to 0.707, so that the crest factor is
equal to 1.41. A perfect sine wave has no impacts and, therefore, the crest factor with a value of over
1.41 means that there is a certain impact degree.
8.13.2.- .WAT FILE
The variable recording period can be configured by the user and is different to the recording period of
an .STD file.
8.13.3.- .EVQ FILE
Events detected are stored in this file. The following data are stored from each one of the events:
• Event Type: Overvoltage, Sag or Interruption.
• Event Date: Date the event occurred. This value is obtained with a ½ Cycle accuracy.
• Event Type: This is stored when the event detected is an interruption, sag or overvoltage.
These events are defined in accordance with the specifications programmed in the QNA500.
The type of event also identifies the phase at which the event occurred.
• Duration of the Event: Duration of the event in milliseconds.
• Maximum/minimum voltage of the Event: When an interruption or sag is produced, the
minimum RMS½(*) voltage value obtained during the event will be stored. The maximum value
will be stored in the event of an overvoltage.
• Average voltage of the event: Average RMS½(*) voltage value obtained during the duration of
the recorded event.
• Voltage before the event: The RMS½* voltage value just before the event was produced will
be stored.
(*) ½ cycle RMS value: effective value of a complete cycle, refreshed every half cycle.
QNA500 8IO Instruction manual

POWER QUALITY ANALYZER QNA500 8IO
8.13.4.- .EVA FILE
This file stores any event that is not related to the power quality analyzer's measurements, such as, for
example, a setup modification, change of time, power supply interruption or deleted files. Therefore,
this file is an incident registry file that acts as an analyzer's supervisor and as a filter against access to
the analyzer.
QNA500 can detect and record the following events, among others:
• Battery Off: It will state the moment when the QNA500 has stopped operating. T his moment
depends on the value programmed for the equipment to work with the internal battery when
there has been an interruption in the auxiliary power supply.
• Power Supply On: Indicates the moment when the power supply is connected to the QNA500
power quality analyzer.
• Power Supply Off: Indicates the moment when the power supply is disconnected from the
QNA500 8IO. The power quality analyzer is powered with the battery at this moment.
• Modified Setup: Records the moment when the analyzer's setup is modified.
• Memory Format: Moment when the user has initialised the internal memory of the QNA500
power quality analyzer.
• Internal memory and force format: An internal memory error has been detected and the
QNA500 analyzer will automatically initialise the whole memory.
• Delete File: Moment when the user has deleted a file from the internal memory of the QNA500
analyzer. When the first piece of data appearing in the .EVE file is the deletion of a file, this
means that the events file has been deleted.
• Change of Time: The equipment's time or date has been changed. This event must be
detected, since hourly modifications between measurements often correspond to time changes.
8.13.5.- .CFG AND .DAT FILES
These files store each transient recorded with the QNA500 power quality analyzer. The information
associated with each transient is composed of a .CFG file and .DAT file.
The format of these files follows the COMTRADE international standard (Common Format for Transient
Data Exchange for power systems), which is a file format for oscillographic data. This protocol is
frequently used by companies for recording oscilloscopes and simulations related to the design of highvoltage substations. The format of the COMTRADE file has been standardised by the IEEE.

9.- INPUT/OUTPUT MODULE SETUP (M-8IO)
M-8IO centralizer module can supervise and control an electrical installation. The M-8IO module can
manage states, alarms and perform energy metering procedures with the use of programmable digital
inputs and outputs, managing the energy pulses received from other installation devices.
In addition to the power of the measurement module, QNA500 can interact with any electrical
magnitude present in the installation, making it easier to control the electrical installation.
M-8IO centralizer module has a built-in WEB server that allows the user to easily and quickly configure
the system from any PC with a WEB browser (for example, Internet Explorer, Mozilla or Chrome,
among others).
Before starting with the setup of alarms and other features, you must be sure that communications are
correctly configured in this module.
9.1.- COMMUNICATIONS
To access to the setup it’s recommendable to use WEB-Server or software provided by CIRCUTOR.
In case of using ETHERNET port, QNA500 is setup with DHCP as default, so if this is connected to a
LAN network, DHCP server of this LAN will provide IP addresses to each module automatically.
To know assigned IP address, or to assign an specific IP address, you can use IP setup software,
which ask you MAC address and allows you to set an specific IP to each module.
By default, M-8iO centralizer has following configuration (depending on model):
• (M-8iO): Device Number, Baud Rate, Length, Parity, Stop Bits: 10, 9600-8-N-1
• (M-8iO-R): Device Number, Baud Rate, Length, Parity, Stop Bits: 10, 9600-8-N-1
All communication ports are MULTIPROTOCOL which means that you can communicate using any of
the supported protocols.
Available protocols are the following:
• MODBUS/RTU (on-line communications)
• MODBUS/TCP (on-line communications)
• CIRBUS (on-line communications)
• ZMODEM (protocol to download files)
• FTP (protocol to download files)
• HTTP: (protocol to connect using Web-Browser)
QNA500 8IO Instruction manual

POWER QUALITY ANALYZER QNA500 8IO
9.2.- Digital inputs
M-8iO centralizer module has 8 digital inputs. These inputs are designed to provide 2 main functions:
• Pulse counting: can be wired up to 8 meters (or other devices) send to send pulses
proportional to measures of physical quantities and M-8iO module will count the number of
pulses and group them in a registration period as a load profile of pulses received.
• Registration status changes (On / Off): T his option allows to record the date / time that an
input is activated and / or deactivated. In the case of circuit breakers or other elements of a
plant want to be aware when they are fired, only one auxiliary contact wiring to the
corresponding input, this option would be recorded.
The digital inputs are capable of detecting pulses of minimum width of 15μs.
The configuration of the digital inputs and monitoring can be done via the web server of the module.
NOTES:
• For more information on configuring the module using the M-8iO web server, see the section
'Web Se rver'.
• For more technical information on the digital inputs, see the section on 'Technical
Characteristics'.
9.3.- Digital outputs
There are 2 models with 8 digital outputs and the difference relays or opto-mosfet. M-8iO centralizer
module has 8 opto-MOSFETs, while the module M-8iOR has 8 relays.
These outputs are designed to provide 4 main functions:
• Pulse proportional to energy (M-8iO): This option allows you to program one or more outputs
to generate pulses proportional to the energy measured by the module QNA500.
• Alarms: T his option allows you to open/close a digital output depending on an electric variable
measured by the analyzer QNA500, or an alarm conditional on a change of state of a digital
input module or another module itself M-8iO.
• Remote Control: Allows you to open or close a digital output at the user, without being subject
to any pre-programmed condition.
• Time operations: this option allows to open/close outputs depending on time conditions. As an
example it’s possible to connect some loads at one specific time and to disconnect them at
some other specific time.
The digital output configuration and monitoring can be done via the web server of the module.

9.5.- ALARM SETUP (Digital objects)
M-8iO centralizer can configure a list of alarms (up to 16 alarms) to manage conditions f rom itself or
from other MULTIFIT modules.
These alarms can be recorded in the memory, used to create actions in other MULTIFIT modules or to
open/reclose digital outputs in the M-8iO centralizer.
There are 3 different types of alarms (or digital objects), as described:
• ALARM OBJECTS: can enable any alarm condition associated to an electrical variable
measured by the QNA500 module.
• ENERGY OBJECTS: these are necessary when associating a pulse output of a M-8IO module.
The most common application is where the pulse outputs can produce pulses proportional to
the energy (A+, A-, Q1, Q2, Q3 or Q4) measured by the QNA500. To do so, first activate an
energy object and activate the pulse output on the M-8IO module. This configuration is
explained in the corresponding chapter of this module.
• TIME OBJECTS: these objects allows to open/reclose a digital output depending on a time
condition.
These alarms (or digital objects) can be associated with the following variables:
These alarms can be linked with others by using conditions (AND, OR, AND NOT, OR NOT).
Moreover, each alarm can be used in a negative or positive logic. Finally, for each alarm user can do
following actions:
• Regist er ala rm in mem ory (with time-stamp)
• Open/reclose digital output (relay or opto-mostfet)
• Send confirmation to other centralizer MULTIFIT (up to 4 modules)
• Send emails (no-emails , list 1,…, list 4)

11.2.- MODBUS/TCP
This protocol is a variation of the MODBUS/RTU protocol that has been specially designed to work with
TCP/IP networks. The queries from various devices can be optionally accumulated in a battery. This
will allow various devices to send data to the QNA5 00 8IO analyzer at the same time and the analyzer
will respond to each specific query. The following port must be used when establishing communications
through the Ethernet port: 30003
11.3.- ZMODEM
This international standard protocol can be used to download files and its main f eature is based on the
repositioning of any frame. This is quite important in communications via modem, where existing delays
or silences in the lines can lead to communication errors. This standard protocol has been specially
designed for an optimum operation in these situations. The following port must be used when
establishing communications through the Ethernet port: 14001 (telnet zmodem) or 14002 (RAW
zmodem).
