Unipi Axon L525

Axon

Unipi Axon L525 is a programmable logic controller (PLC) designed for automation, control, regulation and monitoring. The L525 is the largest model of the Axon 500 line focused on a higher number of analog I/O, but also features a high number of all inputs/outputs available on Unipi products (digital, relay). That makes it suitable for complex projects including measurements and control of analog components. The controller is equipped with four serial interfaces (RS485 + RS232).

The L525 is a development successor to the Axon L505.

Features

  • universal architecture with a high number of I/Os
  • increased number of analog I/Os, four serial lines (RS485 + RS232)
  • 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
  • features RS485 serial line for Modbus communication
  • 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.

Relay outputs (RO) serve for switching devices with higher current draw and devices requiring alternating current (AC) such as water heaters, pumps, contactors or external relays with higher switching current.

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

Analog outputs (AO) are 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, 1.2GHz 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.
