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 field, and are proud to present Core IO! The 16DI provides 16 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 configuration of the device can be achieved through the network using either the web interface (IP version only) or Modbus configuration registers, or by using an Android device and connecting over Bluetooth using the dedicated app. 1.0 4/10/2021 Get help at http://innon.com/support 3 Learn more at http://know.innon.com Core IO 16DI - Manual innon.com This Core IO model Both the CR-IO-16DI-RS and the CR-IO-16DI-IP modules come with 8 digital inputs. The CR-IO-16DI-RS only comes with the RS485 port, while the CR-IO-16DI-IP comes with both RS485 and IP ports. Both models also come with Bluetooth on-board, so configuration can be achieved using an Android device and the dedicated app. The IP CR-IO-16DI-IP model also integrates a web server configuration interface, accessible via a PC web browser.

Each digital input can be configured 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 configured specifically 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 configured to count pulses, a number of Modbus Registers are available with information and commands specifically for the pulse counting function. The pulse input will, in fact count 2 totalizers as follows · The first 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 specified (adjustable) time (in minutes). When the time expires, 1.0 4/10/2021 Get help at http://innon.com/support 7 Learn more at http://know.innon.com Core IO 16DI - Manual innon.com 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 finished 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 configure 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 1.0 4/10/2021 Get help at http://innon.com/support 8 Learn more at http://know.innon.com Core IO 16DI - Manual innon.com CONFIGURING THE DEVICE FIXED SETTINGS The RS485 Modbus Slave communication have some settings that are fixed as follows · 8-bit data length · 1 stop bit · Parity NONE DIP SWITCH SETTING The DIP switches are used to configure 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 configured as follows End of line resistor 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. 1.0 4/10/2021 Get help at http://innon.com/support 9 Learn more at http://know.innon.com Core IO 16DI - Manual The Modbus ID and baud rate DIP switches are configured as follows innon.com 1.0 4/10/2021 Get help at http://innon.com/support 10 Learn more at http://know.innon.com Core IO 16DI - Manual Slave address DIP switch settings, continued. innon.com 1.0 4/10/2021 Get help at http://innon.com/support 11 Learn more at http://know.innon.com Core IO 16DI - Manual innon.com Bluetooth and Android App Core IO has built-in Bluetooth which allows the Core Settings app running on an Android device to configure the IP settings and I/O.
