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.

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.
