7 Introduction Iono Arduino combines the ease of use of the Arduino platform with multiple input and output interfaces; the result is a rugged, safe, reliable and easy to connect module, suited for installation both in industrial and residential environments. Iono Arduino is available in three versions, all using the same shield board and case, but with different Arduino boards pre-installed. Iono Arduino Ethernet has an Arduino Ethernet board, while Iono Arduino Uno uses an Arduino Uno board. Iono Arduino Solo comes without any Arduino board, so you can use your preferred Arduino board, as far as it is fully compatible with the Arduino 1.0 pinout and fits the Iono Arduino case. The different versions all share the same I/O board and case, and the electrical characteristics are common. The information contained in this manual cover all versions, except where explicitly stated otherwise. 6 User Guide

8 Features The Iono Arduino modules key features are: 12 24Vdc power supply compatible with 5.0V and 3.3V operating voltage Arduino boards 4 multi-mode inputs: either to be used as digital or as 0 10V or 0 20mA analog signals 2 digital inputs for potential-free contacts 1 analog output 0 10V controlled by PWM signal redundancy of common terminals for simplified wiring 6 power relay outputs rated for 12A at 250V, which can tolerate large peak currents (inrush current) up to 80A output relays with bistable coil, to minimize the current consumption standard RS-485 interfaces to the Arduino serial pins with automatic TX/RX switching, and electrostatic discharge protection built-in slot for the installation of an Arduino Uno, Arduino Ethernet or Arduino Zero board removable terminal blocks for easier installation inputs protected against electrostatic discharges and temporary over voltages double internal insulation between high voltage areas (relay outputs) and all other components standard modular housing 9 units size, suitable for mounting on Omega rail. 7 User Guide

9 Usage and connections FIGURE 1 CONNECTION EXAMPLE Power supply Iono Arduino can be powered with DC voltage only: DC: nominal voltage in the range 12V to 24V (MIN=11, MAX=30Vdc) Respect the correct polarity shown in the schematic diagram (+ -). The power supply circuit implements reverse polarity protection using an auto resetting fuse and surge protection up to ±500V/2ohms 1.2/50μs. 8 User Guide

10 Multi-mode inputs: analog mode Iono Arduino features 4 multi-mode inputs (1, 2, 3, 4). Depending on terminal blocks wiring, digital (ON-OFF), analog 0 10V or analog 0 20mA signals can be applied. When using analog inputs, 0 10V and 0 20mA are converted to 0 3.3V levels in order to be compatible with the Arduino platform input pins. Both active and passive 0 20mA (or 4 20mA) transmitters can be connected, using the C+ terminal as power supply; the 0 20mA transmitter shown in the schematic here below is a 2-wire passive type. Multi-mode inputs: digital mode In digital mode, an external potential free contact can be connected between terminals C+ and DIx (x=1, 2, 3, 4); otherwise, the DIx terminal can be connected to an external voltage signal (in the range 9 40V) referred to the GND of the Iono Arduino module. DI5 and DI6 digital inputs An external potential free contact can be connected between terminals C+ and DIx (x=5, 6); otherwise, the DIx terminal can be connected to an external voltage signal (in the range 9 40V) referred to the GND of the Iono Arduino module. DI5 and DI6 are connected to the Arduino board through a protection network. If you need to bypass the protection resistors you can move jumpers J1 and J2, respectively for DI5 and DI6, to the BYP position. DI5-DI6 JUMPERS SCHEMATIC NOTICE Note that, with the jumpers in the BYP position, you should limit the maximum voltage applied to DI5 or DI6 to the voltage levels accepted by the Arduino board installed in Iono Arduino. Exceeding the Arduino voltage range will result in damage to the Arduino board and Iono Arduino. 9 User Guide

11 J1-J2 JUMPERS POSITION Analog output Iono Arduino features a 0 10V output (AO1) which can be controlled by the PWM function of the Arduino platform; the 0 100% duty cycle of PWM signal corresponds to a 0 10V output voltage. This is a sink/source output (the current direction at this output can be both positive and negative). Relay digital outputs Iono Arduino features 6 power relay outputs which can withstand high inrush currents thanks to the special contact built. These relays have bistable coils, which are powered only for the short time needed to move the contact from one position to the other one. This guarantees very low total current consumption and low power dissipation resulting in lower self-heating. It also maintains mechanical memory in case of module power supply failure. A dedicated internal circuit manages the relay coils, matching the closed status of each relay to the high state of the related control pin of the Arduino platform. RS-485 serial port Iono Arduino uses the Arduino UART TX/RX pins to implement a standard RS-485 serial port. Simply connect the RS-485 A, B and GND to the RS-485 pins of the terminal block. The RS-485 port is protected from ESD and voltage surges, and supports half-duplex communication with automatic TX/RX switching from 1200 to bps. 10 User Guide

12 The RS-485 TX/RX switching is implemented automatically in the Iono s micro-controller, based on speed and number of bits detection, and is completely transparent to the software controlling the UART on Arduino. The RS-485 line has 620 Ohm pull-up and pull-down resistors on lines A and B. The biasing resistors ensure that, during idle periods the data lines are kept at a stable voltage level and prevent false triggering of receiver input. These resistors can be enabled installing jumpers J4 and J5 respectively. A 120 Ohm termination resistor between A and B can be enabled installing jumper J3. RS-485 JUMPERS SCHEMATIC RS-485 JUMPERS POSITION Mapping The following table shows the mapping of the inputs and outputs of the Iono Arduino module into the related pins of the Arduino platform. 11 User Guide

All digital I/O and the PWM-based analog output A01 work transparently with both 5.0V and 3.3V Arduino pins The 0-10V and 0-20mA analog inputs are translated to a voltage range between 0 and 3.3V to the analog pins of the Arduino boards. If you are using a board with 5.0V operating voltage, you will have to use the external voltage reference (AREF) for the Arduino analogto-digital converter. The Iono Arduino board connects the Arduino AREF pin to 3.3V. If you are using an Arduino board in a way that is incompatible with the 3.3V voltage applied to AREF, you can move the J6 jumper to the OPEN position in order to leave the AREF pin unconnected.

Iono Arduino Ethernet Iono Ethernet ships with our web app sketch pre-installed and the following network configuration: Address: Netmask: Gateway: DNS: connect Iono Arduino to a regulated power source (check the data sheet for the power requirements) 2. check that the LD1 power LED, next to the power supply terminals, is on 3. connect Iono Arduino to your network and, from a device with a compatible network address, go to the following URL using any modern web browser: Note that JavaScript must be enabled on the browser 4. click the settings icon and enter your preferred network parameters and password, then press save 5. you should now be able to access Iono Arduino again using the newly assigned address. Iono Arduino Uno Iono Arduino Uno ships with the Modbus RTU Slave sketch pre-installed. This sketch implements a fully functional standard Modbus RTU slave to monitor and control all I/O lines of the Iono Arduino Uno module, and is also compatible with Arduino Zero. 1. connect Iono Arduino to a regulated power source (check the data sheet for the power requirements) 2. check that the LD1 power LED, next to the power supply terminals, is on 3. read the Modbus RTU Slave chapter below to configure and use Iono Arduino Uno as a Modbus RTU device. Iono Arduino Solo Iono Arduino Solo doesn t ship with a pre-installed sketch, for the simple reason that there is no Arduino module installed! Before installing your own Arduino board, you should check that it powers-up normally. 1. connect Iono Arduino to a regulated power source (check the data sheet for the power requirements) 2. gently remove the side covers on both sides 3. check that the LD1 power LED, next to the power supply terminals, is on 13 User Guide

15 4. remove the power supply 5. install your Arduino board and replace the side covers 6. reconnect the power supply and check that LD1 goes back on 14 User Guide

16 Iono Arduino Ethernet web app user guide The pre-installed Iono Arduino Ethernet web app can be used from any modern browser, including browsers of all mobile devices, to easily control the output relays, the 0 10V analog output and check the status of all inputs. JavaScript must be enabled on the browser, or this app will not work. Simply push the DOx switches to flip the relays, or enter a decimal number, e.g. 8.3, then press [set] to set the analog output. From the control page you can access the configuration page pressing the icon on the topright corner. Using the configuration page you can change the network parameters, including the MAC address (unless you know exactly what you are doing, always use the MAC address printed on the Arduino Ethernet board). You can also set a password to restrict access to the web app. Please note that this app does not use the HTTPS encrypted protocol and all data, including the password, are sent over the network unencrypted. Factory reset The web app sketch implements a simple factory reset procedure, to restore the original network settings and remove the password. Power off Iono, then short-circuit pins RX and TX and power it back on. Now go to set the new configuration and save, wait for the process to complete and remove the short-circuit. HTTP API The web app includes an HTTP API for remote control from networked applications. Visit this page for the details: 15 User Guide

17 Modbus RTU Slave user guide In order to use Iono Arduino Uno as a Modbus RTU device, you first need to configure the RS-485 communication parameters and Modbus address. A simple serial configuration console is implemented in the sketch. Console The configuration console is accessed through the same serial port used for the Modbus communication. Set the serial port speed to 9600, 8 bits, no parity, no flow-control and connect to the Arduino s serial port using the Arduino USB port and your preferred serial terminal program. You can also connect via the RS-485 terminal block on the Iono Arduino Uno Module. When the Arduino Uno is powered-up or reset, you can enter console mode by typing five or more consecutive space characters within 15 seconds from reset. If any other character is received, Arduino will enter the normal Modbus RTU mode. Press 0 to show the current configuration, 1 to 3 to enter the serial port speed, serial port parity, and the Modbus address. Sfera Labs Iono Uno (2.0) - Modbus RTU slave configuration menu 0. Print current configuration 1. Speed (baud) 2. Parity 3. Modbus device address 4. Input/Output rules 5. Save configuration and restart Type a menu number (0, 1, 2, 3, 4, 5): 0 Current configuration: Speed (baud): Parity: Even Modbus device address: 2 Input/Output rules: Press 4 to define the Input/Output rules. With these rules you can configure each one of the 6 digital inputs to control the corresponding output relay. The rules string consists of six characters, where the leftmost character represents the rule for DI1/DO1 and the rightmost character for DI6/DO6. The possible rules are: F: follow - the relay is closed when input is high I: invert - the relay is closed when input is low H: flip on L>H transition - the relay is flipped at any input transition from low to high L: flip on H>L transition - the relay is flipped at any input transition from high to low T: flip on any transition - the relay is flipped at any input transition, both high to low and low to high 16 User Guide

18 -: no rule - no control rule set for this relay. Press 5 to review the configuration and confirm to save it. When the new configuration is saved, Arduino will automatically reset and restart with the new configuration. The configuration is permanently stored in the Arduino s EEPROM memory, and retained across restarts and power cycles. Modbus address tables and functions Relays Use Modbus function Read Coils, at coil address 1 to 6, to read the status of the last command given to the output relays. Because the relays are latching, the status will return zero at boot, regardless of the actual position of the relays contacts. Use functions Write Single Coil or Write Multiple Coils to control the relays output.

21 Installing and removing the Arduino board With Iono Arduino Solo you will have to install your own Arduino compatible board. Iono Arduino accepts the original Arduino Uno and Ethernet Rev 3 boards, or other boards that are fully compatible with the Arduino 1.0 pinout specification, with 5.0V or 3.3V operating voltages. Installing boards that are not fully compatible, both mechanically and electrically, may and probably will damage the Iono Arduino board, and may create a safety risk. You are responsible for the installation of the Arduino board inside Iono Arduino Solo. The factory warranty does not cover any damage directly or indirectly caused by the installation and removal of Arduino or compatible boards in Iono. Iono Arduino Solo is shipped with two plastic turrets next to the Arduino pins. These turrets should fit in the corresponding holes on your board. You may want to remove the turrets if they don t fit your board. It is up to you to determine if the mechanical coupling between Iono Arduino and the Arduino board is appropriate for your application. FIGURE 2 TURRETS INSTALLED ON THE IONO ARDUINO BOARD To install the Arduino board, first line-up the connectors pins on both sides and also the Arduino board holes with the turrets heads. Visually confirm the alignment, then gently push down on both sides at the same time to lock the board firmly in place. FIGURE 3 AN ARDUINO BOARD WITH PINS AND TURRETS PROPERLY ALIGNED To remove the board, you should apply a gentle pressure to separate the turrets heads from the board. Be very careful to keep the Arduino board parallel to the Iono Arduino 20 User Guide

22 board at all times, or you will bend the connection pins. You may consider cutting the turrets to simplify the removal of your Arduino board. 21 User Guide

23 Iono Arduino Software Development Since Iono Arduino is just a super-sized I/O shield for a standard Arduino, you don t need any specific library to work on it. Our libraries and examples, available with source code on GitHub, will provide you with some handy utilities to speed up your development, including functionalities to monitor the inputs (filtering out possible noise) and control the outputs, HTTP APIs, Modbus support and much more. Go to to access the code and documentation. Programming Arduino Uno The Arduino Uno board, when mounted into a Iono Arduino module, must be programmed through the USB port. Arduino Ethernet The Arduino Ethernet board requires the USB Serial Light Adapter for programming, as shown below. FIGURE 4 THE USB SERIAL ADAPTER In order to access the programming connector inside the Iono Arduino module, the cover placed on the same side of the power supply terminal block must be removed, gently sliding it outward, and giving access to the programming connector indicated by the red arrow. The yellow arrow indicates the reset button of the Arduino board. 22 User Guide
