Unipi Patron

Unipi Patron is a product line of programmable logic controllers designed for automation, control and monitoring. High computing power, software openness and flexibility make the Patron products the most powerful compact PLCs available on the market. Patron is suitable for a wide range of applications ranging from building management and industry to HVAC and SCADA systems to smart home installations and other automation projects. An extended 4-year warranty is provided for all Patron models.

Note: The availability of LTE models is scheduled for Q4/2021. You can already make a preorder on our e-shop.

Depending on the specific model, Patron controllers feature 1-3 sections (additional info available below.

Each section has its own STM32 microprocessor that controls the section's I/Os and communicates with the controller's CPU. The processors use their own firmware containing not only basic I/O functionality but also a variety of additional functions and features.

All components are protected by a durable chassis made from anodized aluminium that provides IP20 protection against external hazards. The chassis can be customized to your needs - for more info, please visit the OEM solutions page.

Powerful CPU for the most demanding projects

Patron programmable logic controllers are based on a Unipi-developed computing module powered by the i.MX 8M Mini (4× Arm® Cortex®-A53) CPU that features a max. 1.8 GHz frequency, 1GB RAM and an onboard 8GB eMMC memory. These features make Unipi Patron the most powerful compact PLCs on the market. Using our own computing module allows us to provide support on all levels, a realization of various modifications within the custom manufacturing programme and more options for standard development (eg. integration of new communication protocols).

A wide selection of inputs/outputs

Depending on the specific model, Patron controllers can feature the following types of inputs/outputs and their combinations:

  • DI - digital inputs
  • DO - digital outputs
  • RO - relay outputs
  • AI - analog inputs
  • AO - analog outputs

Additional info about Patron I/Os is available in the following article

The modular construction of I/O boards allows us to easily modify already existing I/O combinations or create new ones as part of the custom manufacturing programme.

In case you need to extend your project by additional inputs/outputs, a simple and affordable solution is available in the form of Unipi Extension modules. The modules communicate using the RS485 interface (Modbus RTU protocol) and provide you with more inputs and outputs without the need to purchase additional controllers.

Communication interfaces with broad connectivity

Depending on the model, Patron controllers can feature up to 4 RS485 serial lines, RS232 serial line, a single 1-Wire bus or a combination of the all mentioned interfaces.

  • RS485 and RS232 interfaces serve for connection of various external devices (extension modules, energy meters, HMI panels, various sensors), or communication with gateways and closed technologies,
  • The 1-Wire bus is designed to communicate with 1-Wire sensors such as temperature and humidity sensors,
  • A pair of USB 2.0 ports can be used to connect wireless adapters, external storage disks or serial converters,
  • all Patron controllers feature a single 100Mbit Ethernet port for network communication,
  • S167, M267 and M567 models also feature an LTE mobile connection that allows the PLC to use the LTE wireless network for internet connection.

As with inputs and outputs, our custom manufacturing program offers you an option to customize the number and type of communication interfaces.

Sizes and sections

Unipi PLCs are available in three sizes:

  • Type S: max. 10 inputs and outputs, 70 × 90 × 60 mm (4 DIN modules)
  • Type M: max. 40 inputs and outputs, 140 × 90 × 60 mm (8 DIN modules)
  • Type L: max. 70 inputs and outputs, 210 × 90 × 60 mm (12 DIN modules)

Depending on the model, Unipi controllers feature 1-3 sections, with each section containing a group of inputs, outputs or communication interfaces. Unipi controllers can have 1 (S-series), 2 (M-series) or 3 (L-series) sections, as shown on the picture below:

Labels S, M and L allow for a quick distinction between controller sizes. The section numbers is important for the software, especially for addressing input and output boards. The special section number is 0, through which in some cases all three sections can be accessed simultaneously.

Patron controllers are based on the Linux open-source operating system, ensuring compatibility with a wide variety of software solutions, both commercial and open-source. By default, all controllers are shipped with a pre-installed Mervis system - a professional software platform that includes development environment, SCADA interface, cloud database and other components. Alternatively, you can utilize a Unipi-developed open-source application programming interface (API) for the integration of your software or any of the supported third-party solutions (Node-RED, openHAB, FHEM, Pimatic etc.). For more info, please visit the Choosing the right software article.

Broad communication options, high computing power, software openness, compact size, a large selection of models and customization options - these features make the Patron product line an ideal choice for a wide variety of projects and installations:

  • smart home,
  • control and monitoring systems,
  • HVAC control systems in buildings,
  • monitoring and optimization of energy consumption and precise invoicing,
  • SCADA system for remote monitoring and management,
  • monitoring and automation of data centres,
  • monitoring and regulation of photovoltaics,
  • irrigation control and energy regulation in agriculture,
  • Smart City systems,
  • a gateway between technologies,
  • and many more.

Unipi Patron offers many options for custom development and manufacturing. Patron controllers can be extended by the integration of wireless technologies (LTE, Zigbee, Enocean), new communication protocols or additional functionality (eg. PoE, Secure boot or support of external modems or PCIe modules). It is also possible to create custom I/O combinations.

Customization options also include the operating system (OS) image - a large archive containing all that’s needed to start and run applications on controllers. Aside from the image customization according to your needs, it is also possible to upload the image into the controllers during their assembly. Thanks to this feature, the controllers are delivered already pre-configured, which allows you to save a considerable amount of time when preparing the controllers for deployment. For more info about custom OS images, please visit this link.

All of the above-mentioned options, combined with graphic customization of the chassis and software openness, allow you to obtain a controller with software and hardware tailored to the needs of your project. This makes the Patron line an excellent choice for software developers and companies offering Unipi PLCs as part of their solutions.
