Axon

Unipi Axon S105 is a programmable logic controller (PLC) and gateway designed for automation, control, regulation and monitoring. The S105 is a compact model with a universal architecture combining digital and analog I/Os suitable for simple installations. The controller also features three serial interfaces (RS485 + RS232) for connection of extension modules and/or gateways, and a 1-Wire interface for connection of temperature or humidity sensors.

Features

  • most versatile Axon variant
  • combination of small dimensions, 10 I/Os and three serial lines (RS485 + RS232)
  • durable aluminium chassis (IP20 protection), wider operating temperature range
  • integrated industrial computer (quad-core CPU, 1 GB RAM)
  • onboard 8 GB 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 states of two-state devices such as various digital sensors, switches, and buttons, motion sensors, etc. All digital inputs feature counter functionality by default. 

Digital outputs (DO) are applicable for switching two-state devices using direct current (DC) such as locks, external relays, contactors, etc. DO’s can be also used for analog control thanks to the pulse-width modulation (PWM) function.

Analog input (AI) is designed to measure voltage, current, or resistance in order to read values from various analog sensors (pressure meters, thermometers, tension gauges, etc.).

Analog output (AO) is used to control and regulate devices such as three-way valves, electric motors, inverter drives, heat exchangers, etc. by direct current or voltage.

Computing module

Axon controllers are powered by a quad-core, 1.2 GHz Alwinner H5 CPU and feature 1 GB RAM for an excellent performance. The 8 GB 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 1 Gbit 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 an 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.
