INTRODUCTION
Overview
In many installations, having cost eective, 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 conguration of the device can be achieved through the network using either the web interface
(IP version only) or Modbus conguration registers, or by using an Android device and connecting
over Bluetooth using the dedicated app.

HARDWARE
Overview
Wiring Power Supply
AC (24Vac) DC (24Vdc)
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 conguration can be achieved using an
Android device and the dedicated app.
The IP CR-IO-8DI-IP model also integrates a web server conguration interface, accessible via a PC
web browser.

Please note - both IP and RS versions can use the RS485 port to respond to serial Modbus master
comms from the BEMS, but neither version can use the RS485 port to act as a Modbus master
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 congured 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 congured specically 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 congured to count pulses, a number of Modbus Registers are available with
information and commands specically 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 specied (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 congure 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 congure 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 congured as follows –

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.
