Axon

Unipi Axon S215 is a programmable logic controller (PLC) and gateway designed for automation, control, regulation and monitoring. The S205 features a combination of digital inputs and relay outputs while retaining its compact size. The controller is thus suitable for a wide range of applications in smaller installations that include monitoring, reading data from binary sensors and switching of external devices via relay outputs. The S215 also features a pair of serial interfaces (RS485 + RS232) for connection of extension modules or gateways. 

Features

  • combination of digital inputs and relay outputs
  • 16 I/Os and two serial lines in a 4 DIN package 
  • RS485 + RS232 serial lines
  • durable aluminium chassis (IP20 protection), wider operating temperature range
  • integrated industrial computer (quad-core CPU, 1 GB RAM)
  • onboard 8GB eMMC memory
  • designed for DIN rail mounting
  • software openness (based on Linux OS)
  • preinstalled Mervis software (can be manually reflashed)

Inputs & outputs description

Digital inputs (DI) are designed for reading logic states represented by direct voltage levels. That makes DI's suitable for reading data from various two-state (binary) devices and sensors such as switches (on/off), motion sensors (movement/no movement), liquid level sensors (tank empty/tank full) etc.

Relay outputs (RO) serve for switching device with a high current draw, ie. light bulbs, thermoelectric drives, water heaters, pumps, larger external relays etc.

Computing module

Axon controllers are powered by a quad-core, 1.2GHz Alwinner H5 CPU and feature a 1GB RAM for an excellent performance. The 8GB onboard eMMC memory then offers better reliability compared to systems relying on microSD cards as memory storage. 

Communication interfaces

By default, all Axon controllers feature RS485 serial lines. This type of interface usually uses the Modbus RTU protocol and can be used for communication 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 its 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 available 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 200 meters. 

By default, all Axon controllers feature a single 1Gbit Ethernet port for network communication. 

Software options

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 platform Among supported solutions are both commercial and open-source systems. Visit the Other software overview for the list of other supported solutions.

The main supported solution is the Mervis control system - a platform developed under the IEC 61131-3 standard for PLC programming, that includes SCADA interface for remote management and monitoring, a comprehensible development environment, a human-machine interface (HMI) editor and an online/on-premise database for storing historical data and retrospective analysis of the controlled technology's operation. 

Aside from commercial platforms you can also choose any from the list of supported open-source solutions, or use the EVOK API (Websocket, REST,...) Modbus TCP, SysFS or other tools for implementing your logic in any programming language. Visit this link for the list of supported software solutions.
