UniPi Axon S115 is a programmable logic controller (PLC) designed for control, monitoring and regulation. The S115 features four RS485 lines, being designed primarily for the control of extensive automation networks
UniPi Axon S115 is a specialized variant of the basic S105 model. The I/O configuration remains unchanged with the exception of replacing an RS232 line with three additional RS485 lines. That gives the S115 a total of four RS485 lines. The unit can be utilized in various systems requiring either interconnection between technologies from different vendors, or interconnection of several devices using different communication protocols.
4 digital inputs (DI) are designed for reading logical states (true or false), which are represented by levels of DC voltage. That makes them suitable for reading two-state sensors such as switches (on/off), movement sensors (movement/no movement), water level sensors (water present, no water) etc. The software detects logical 1 (true) if the input voltage between given DIx.y and DIGND is between 5-35V. If the voltage is lower than 3.5V, the state is evaluated as 0 (false)
4 digital outputs (DO) are used for controlling two-state devices such as lights, door locks, window blinds etc. Digital outputs on our controllers also feature the PWM (Pulse-width modulation) function, enabling a special type of analogue control. Outputs are of the NPN type (open collector) and are able to control devices with voltage up to 50V and up to 750mA load current.
1 analogue input (AI) can be used for 0-10V DC voltage or 0-20mA current measuring, making them suitable for reading values from analogue sensors such as temperature sensors, pressure meters, tensometers etc.
1 analogue output (AO) features two modes - 0-10V DC voltage or 0-20mA direct current. AI serves for control of devices with analogue input, such as three-way valves, lighting dimmers etc.
The unit features a pair of RS485 serial lines. This type of serial line most often uses the Modbus RTU protocol. It can be used for communication with a wide variety of devices such as energy meters, touchscreen HMI panels, PLCs from other vendors or our Neuron xS extension modules. The bus can communicate with up to 32 devices with its total length being up to several hundred meters.
The controller also features a single RS232 serial line for communication between two devices. In automation, it is most often used for communication with HMI displays, various gateways or closed technologies.
Included is a single 1-Wire bus, using 2 or 3 conductors for communication with simple sensors such as thermometers, humidity meters or light intensity meters. A single bus can communicate with up to 15 sensors with a maximum total length of the bus up to 100 meters.
For network communication, a single 1Gbit Ethernet is provided.
Customers can choose from a wide variety of software solutions thanks to the open nature of Axon controllers and are not limited to a single platform. Available are both professional and open-source solutions.
Our main supported solution for UniPi controllers is the Mervis. This platform is developed in accordance with IEC 61131-3 PLC programming standard and contaiíns SCADA interface for remote management and monitoring, comprehensible development environment, user interface (HMI) editor and online/on-premise database for data storage and retrospective operation analysis of monitored technologies.
Aside from commercial platforms, several open-source solutions are available as well. Alternatively, customers can use their own code or implement Axons into already existing software solutions through the use of EVOK open-source API.
