INTRODUCTION
Overview
In many installations, having cost eective, robust, and simple hardware becomes a key factor in
winning a project. The Core line up provides the perfect solution to meet these criteria. Innon have
partnered with Atimus, a company with a wealth of experience in the eld, and are proud to present
Core IO!
The 8DI provides 8 digital inputs. As well as monitoring volt free contacts, the device also allows the
use of pulse counters.
BEMS communication is based on the robust and well proven Modbus RTU over RS485 or Modbus
TCP (IP model only).
The conguration of the device can be achieved through the network using either the web interface
(IP version only) or Modbus conguration registers, or by using an Android device and connecting
over Bluetooth using the dedicated app.

Overview
Wiring Power Supply

This Core IO model
Both the CR-IO-8DI-RS and the CR-IO-8DI-IP modules come with 8 digital inputs.
The CR-IO-8DI-RS only comes with the RS485 port, while the CR-IO-8DI-IP comes with both RS485
and IP ports.
Both models also come with Bluetooth on-board, so conguration can be achieved using an
Android device and the dedicated app.
The IP CR-IO-8DI-IP model also integrates a web server conguration interface, accessible via a PC
web browser.

or gateway.

Digital Inputs
Digital Inputs can have a clean/volt free contact connected to Core IO to read its open/closed status.
Each digital input can be congured to be either:
• Digital Input direct
• Digital Input reverse
• Pulse input
While the “direct” and “reverse” mode would basically return status “False (0)” or “True (1)” when
the contact is either open or closed, the third mode “pulse input” is used to return a counter value
increasing by 1 unit every time the digital input closes; please read section below for more details
regarding pulse counting.
Pulse Counting
Digital Inputs and Universal Outputs can be congured specically to work as pulse counting inputs.
The counting maximum readable frequency is 100Hz, with a duty cycle of 50% and the maximum
“contact closed” readable resistance is 50ohm.
When an input is congured to count pulses, a number of Modbus Registers are available with
information and commands specically for the pulse counting function.
The pulse input will, in fact count 2 totalizers as follows –
• The rst one is continuous; it will increase by one unit for every pulse received and will keep
counting until a reset command is sent over Modbus
• The other totalizer is timed. Basically, it will also increase by one unit for every pulse received
but will count only for a specied (adjustable) time (in minutes). When the time expires,
this second counter will start counting again from “0” immediately, repeating the cycle, but
will hold the last resulting value for a minute in the register (counting the next cycle in the
background)

Each pulse counting input has the following Modbus registers associated with it –
• counter (totalizer): this is the main totalizer. It will go back to “0” only if a reset command is sent,
or if Core IO is power cycled – you can also write to this value to restore a previous count if replacing
a module or to reset to 0
• counter (timer): this is the second totalizer, the timed one. It will go back to “0” every time the
timer reaches the maximum set value (with delay of 1 minute), or if Core IO is power cycled. If the
counter reset is activated, the counts within the timed cycle will be ignored and the counter timer
reset to 0. The reset will not reset this count to 0 after it has nished a timed cycle and is displaying
the result for 1 minute
• counter timer: this data point returns the current time of the counter, in minutes. It will of course
go back to “0” when it reaches the maximum set value
• counter timer set: using this data point you can congure the duration of the timer for the second
totalizer (max set value), in minutes. This value is stored within the Core IO memory
• counter reset: using this data point you can reset totaliser counter to value “0” and the timed
counter will discard counts up to that point in the timed cycle and reset its timer to 0. Core IO will
self-reset this data point to value “0” once the command has been executed

CONFIGURING THE DEVICE
FIXED SETTINGS
The RS485 Modbus Slave communication have some settings that are xed as follows –
• 8-bit data length
• 1 stop bit
• Parity NONE
DIP SWITCH SETTING
The DIP switches are used to congure the other RS485 settings and the Modbus
slave address thus –
• RS485 End-Of-Line (EOL) resistor
• RS485 Bias resistors
• Modbus Slave Address
• RS485 Baud-Rate
The bank of two EOL (End-Of-Line) blue DIP switches are congured as follows –
End of

Please check our dedicated knowledge base article available at the
website http://know.innon.com where we explain in detail the use
of the termination and bias resistors on RS485 networks.

Bluetooth and Android App
Core IO has built-in Bluetooth which allows the Core Settings app running on an Android device
to congure the IP settings and I/O.
Please download the app from Google Play – search for “core settings”
Download and install the app, then check/make the following settings changes –
• Open your phone settings (drag down from top, press “cog” icon)
• Click on “Apps”
• Select “Core Settings” app
• Press “Permissions”
• Press “Camera” – set to “Allow only while using the app”
• Go back then press “Nearby devices” – set to “Allow”
The Android device will ask you to allow the Bluetooth devices to pair on the rst connection,
watch out for the notications on your device and accept them.
When you run the app, the camera will switch on, and you will need to use it to read the QR code
on the module you wish to set up, i.e. –

Once connected, you will land on the I/O setup screen, where you can set up the I/O and read
input and output current values –
Use the drop-down arrows in the “I/O Mode” column to select the type of input type by clicking in
the respective radio button –
Once you make a change or number of changes, the “UPDATE” button on the bottom
right will go from greyed-out to white; press this to commit your changes.
Click on the “ETHERNET” button (bottom left) to set-up the required IP settings.
Set and commit data as per the I/O method above.
Click on “MODE” button (bottom left) to get back to the I/O settings.

Ethernet Port and Web Server Conguration (IP version only)
For the IP models of Core IO, a standard RJ45 socket is available to be used for:
• Modbus TCP (slave) communication
• Web server access to congure the device
The IP models still provide access on the RS485 port for Modbus RTU (slave) communication on
these models, so the user can decide which one to use to connect the BEMS to Core IO.
The default settings of the IP port are:
IP address:
Subnet:
Gateway address:
Modbus TCP port:
Http port (web server):
Web server user:
Web server password:
192.168.1.175
255.255.255.0
192.168.1.1
502 (xed)
80 (xed)
atimus (xed)
HD1881 (xed)
IP address, subnet and gateway address can be changed from the Bluetooth Android app or from
the web server interface.
The web server interface looks and works in much the same way as the Core Settings app described
in the previous section.

BEMS POINT LISTS
Modbus Register Types
Unless otherwise stated in the tables, all I/O point values/statuses and settings are held
as Holding Register Modbus data type and use a single register (16 bit) to represent
an Integer (Int, range 0 - 65535) type of data.
Pulse count registers are 32-bit long, unsigned registers, i.e. two consecutive 16-bit registers
combined, and their byte order is sent in little endian, i.e. –
• Niagara/Sedona Modbus driver – 1032
• Teltonika RTU xxx – 3412 – also use 2 x “Register count/values” to obtain all 32 bits
For some Modbus master devices, the decimal and hex register addresses in the table will need to
be incremented by 1 to read the correct register (e.g. Teltonika RTU xxx)
Bit-eld data type uses individual bits from the 16 bits available on the Modbus register to provide
multiple Boolean information by reading or writing a single register.
