Arduino Opta® Collective Datasheet 11 / 21 Arduino Opta® Collective Datasheet Modified: 15/11/2024 The microcontroller is a dual-core STM32H747XI. The main processor is a Cortex®-M7 running at up to 480 MHz and the second one is a Cortex®-M4 running at up to 240 MHz. Arduino Opta® can be programmed using the libraries developed for it as part of the standard Arduino Core library. Encryption capabilities are provided by the ATECC608B chipset. This crypto-chip can be used to store sensitive information like security keys to connect to the Arduino® IoT Cloud or other third-party services, protecting Arduino Opta® from any unauthorized access in any kind of industrial and professional environment. TCP/IP and Modbus TCP communication are supported. The 10/100 Ethernet physical interface is directly connected to the internal Ethernet MAC and provides full-duplex communication with automatic MDIX support. With an internet connection, Ethernet communication can be used to connect the device to the Arduino® IoT Cloud or other third-party services.
Arduino Opta® Collective Datasheet 12 / 21 Arduino Opta® Collective Datasheet Modified: 15/11/2024 B(+) A(-) GNDGND B(+) A(-) GNDA(-) B(+) Modbus RTU wiring diagram using the RS-485 interface Modbus RTU communication is supported using Arduino Opta's RS-485 physical interface. Note that Arduino Opta® does not have internal terminator resistors so they need to be added if necessary following the Modbus protocol specification. The wiring indication may vary depending on the connected device. In case the above connection indication is not resulting in consistent data transmission, invert the wires between A(-) and B(+) and retry.
Arduino Opta® Collective Datasheet 13 / 21 Arduino Opta® Collective Datasheet Modified: 15/11/2024 The onboard wireless module allows simultaneous management of Wi-Fi® and Bluetooth® connectivity. The Wi-Fi® interface can be operated as an Access Point, as a Station or as a dual-mode simultaneous AP/STA, and can handle up to 65 Mbps transfer rate. Bluetooth® interface supports Bluetooth® Low Energy (4.2). With an internet connection, the Wi-Fi® communication can be used for connecting to the Arduino® IoT Cloud or other third-party services. The USB-C® port can be used as a host or as a peripheral, but it cannot be used for both purposes at the same time. It is possible to use the connector to power the processor and flash it, but not to power the PLC outputs and peripherals. Additionally and using a USB memory stick, the USB-C® connector can be used for data logging purposes or to update the program inside the PLC. Arduino Opta® has four Normally Open (NO) powerful 10A relays which are capable of actuating on loads at a rated voltage of 250 VAC and up to a maximum switching voltage of 400 VAC. The relay Maximum Peak Current is defined as the highest value of inrush current that the relay can endure without undergoing any permanent degradation of its characteristics due to the generated heat. The relay has to be able to hold up that maximum using a duty cycle of less or equal to 10% and for a time equal to or less than 0.5 s. In the case of Arduino Opta®, relays have a Maximum Peak Current of 15A. The Rated Load is the maximum resistive load that a contact can make, carry and break repeatedly. For resistive or slightly inductive loads (AC1 classification), Arduino Opta's Rated Load is 2500 VA. For small electromagnetic loads (> 72 VA) (AC15 classification) like power contactors, magnetic solenoid valves, electromagnets and AC single-phase supplies, Arduino Opta's Rated Load is 500 VA. This value assumes a peak inrush current of approximately 10 times the rated current and keeping it within the maximum peak current. For controlling DC loads (DC1 classification), the Breaking Capacity or maximum value of DC resistive current that a contact can make, carry and break repeatedly, is 10/4/0.3/0.12 A for respectively 24/30/110/220 V. In the case of the minimum switching load parameters, the minimum values of power, voltage and current that the relays can reliably switch, are 300 mW/ 5V / 5mA. This implies that with 5V the current must be at least 60mA, with 24V, it must be at least 12.5mA, and with 5mA the voltage must be at least 60V. The relays on Arduino Opta® provide a very fast response time of 6/4 ms to change state for closing/reopening, and a bounce time NO/NC of 3/6 ms.
Arduino Opta® Collective Datasheet 14 / 21 Arduino Opta® Collective Datasheet Modified: 15/11/2024 The expansion port can be used to expand the Arduino Opta® capabilities with the help of additional modules. It supports up to 5 expansion modules. To avoid potential communication issues, ensure the total number of connected modules does not exceed 5. If any issues occur with module detection or data exchange, double-check the connections and ensure the Aux connector and clips are securely installed within the expansion port. If problems persist, inspect for any loose or improperly connected cables. A pushbutton is accessible on the front panel of the Arduino Opta®. The functionality of this button can be configured via software. Note that the LED above the User button is only available on Arduino Opta® WiFi (AFX00002). To avoid and reduce electrical noise, Arduino Opta® has a Functional Earth connector (Ref: 3G) near the Ethernet connector. Functional Earth, not to be confused with Ground, helps the device to reduce electrical interferences in industrial environments, being crucial for having stable Fieldbus communications.
Arduino Opta® Collective Datasheet 15 / 21 Arduino Opta® Collective Datasheet Modified: 15/11/2024 If you want to program your Arduino Opta® while offline you need to install the Arduino® Desktop IDE [1]. To connect the Arduino Opta® to your computer, you will need a USB-C® cable. All Arduino® devices work out-of-the-box on the Arduino® Cloud Editor [2] by just installing a simple plugin. The Arduino® Cloud Editor is hosted online, therefore it will always be up-to-date with the latest features and support for all boards and devices. Follow [3] to start coding on the browser and upload your sketches onto your device. Arduino Opta® can be also programmed using the industrial-standard IEC 61131-3 programming languages. Download the Arduino® PLC IDE [4] software and connect your Arduino Opta® to your computer, using a simple USB-C® cable, to start creating your own PLC industrial solutions. All Arduino® IoT enabled products are supported on Arduino Cloud which allows you to log, graph and analyze sensor data, trigger events, and automate your home or business. Sample sketches for Arduino Opta® can be found either in the “Examples” menu in the Arduino® IDE or the “Arduino Opta® Documentation” section of Arduino® [5].
Arduino Opta® Collective Datasheet 16 / 21 Arduino Opta® Collective Datasheet Modified: 15/11/2024 Now that you have gone through the basics of what you can do with the device, you can explore the endless possibilities it provides by checking exciting projects on ProjectHub [6], the Arduino® Library Reference [7] and the online store [8] where you will be able to complement your Arduino Opta® product with additional extensions, sensors and actuators. MTBF, which stands for Mean Time Between Failure, is calculated according to statistical device failures and indicates the reliability of a device. The MTBF figure (in hours/years) for each Arduino Opta® variant can be found in the table below. The MTBF figure was calculated according to the MIL-HDBK-217F parts count method. Standard All Opta® Variants Environmental Conditions MIL-HDBK-217F 766205 h/87 years 25 ºC Important note: MTBF is the statistical representation of the likelihood of a unit failing and does not necessarily represent a product's life.
