O controlador lógico programável (PLC) UniPi Axon S215 apresenta arquitetura de I/Os combinando entradas digitais e saídas de relé, mantendo as dimensões compactas para DIN rail. O S215 é uma variante do modelo S205, com o barramento de 1 fio sendo substituído por uma única linha serial RS232.
UniPi Axon S215
- combina entradas digitais e saídas de relé
- 16 I/Os e 1 linha serial em um pacote de 4 DIN
- linhas serial RS485 + RS232
- chassi de alumínio durável (proteção IP20), faixa de temperatura operacional mais ampla
- computador industrial integrado (CPU quad-core, 1 GB de RAM)
- memória eMMC de 8GB integrada
- projetado para montagem em calha DIN
- software de gestão (baseada no Linux OS)
- software Mervis pré-instalado (pode ser atualizado novamente)
The I/O architecture of the UniPi Axon S215 model is focused on a higher number of digital inputs and relay outputs. Thanks to 8 digital inputs and 8 relay outputs, the S215 can offer an I/O number comparable with larger units while retaining compact dimensions. That makes the S215 especially suitable for smaller automation tasks. In contrast to the S205 model, the S215 has the 1-Wire bus replaced by an RS232 line, making the unit suitable for connection of various third-party devices

Inputs & outputs description
Digital inputs (DI) are designed to read binary logic states represented by direct voltage levels. That makes them suitable for reading data from various binary sensors and devices such as switches (on/off), motion sensors (movement detected/not detected), liquid level sensors (full tank/empty tank) etc.
Relay outputs (RO) are primarily used for switching two-state devices with higher current draw such as lightbulbs, thermoelectric valve drives, water heaters, pumps etc.
As a computing module, the Axon controllers use an industrial computer featuring a quad-core, 1.2GHz Alwinner H5 CPU and 1GB RAM, giving Axons an excellent performance. The 8GB onboard eMMC memory then offers better reliability compared to systems relying on microSD memory cards.
Axon controllers are by default provided with RS485 serial lines. This type of interface usually uses the Modbus RTU protocol and can be used to communicate with various devices such as Extension xS extension modules, energy meters, touchscreen HMI displays, controllers from other vendors, various sensors etc. A single bus can support dozens of devices while the bus' length can reach up to several hundred meters.
Selected models also feature a single RS232 serial line. In the field of automation, this interface is usually used for communication with various converters, closed-in technologies or display devices such as HMI panels.
A single 1-Wire bus is also featured on selected models. This interface uses 2-3 conductors for collecting data from various 1-Wire sensors such as thermometers, humidity meters, light intensity sensors etc.). A single 1-Wire bus supports up to 15 devices, the overall length of the bus can reach up to 100 meters.
All Axon models also feature a single 1Gbit Ethernet port for network communication.
Thanks to the software openness of Unipi controllers customers can choose from a broad range of software solutions and are not limited to a single proprietary platform. Among supported solutions are both commercial and open-source systems.
The main supported platform for Unipi controllers is the Mervis control system. This platform is developed under the IEC 61131-3 PLC programming standard and consists of comprehensible and user-friendly Mervis IDE development environment, an HMI editor for creating and editing of user interfaces, SCADA interface and an online/on-premise cloud database for long-term collecting of operational data and their analysis. Axon-line controllers are shipped with the Mervis already installed.
Aside from commercial platforms (such as CODESYS), customers can also choose from a variety of open-source solutions; for the supported software overview please visit this link.
Alternatively, customers can use the Unipi-developed EVOK open-source API to integrate Unipi controllers into already existing software solutions, use custom code or to develop applications for the controllers.
All components of the controller are encased within a durable aluminium chassis (IP20 protection). The controller is designed for mounting on a standard DIN rail (35 mm).
