HARDWARE

What is the difference between Unipi Patron, Neuron, and 1.1?


   Product line Key properties Fields of application
Unipi 1.1 and 1.1 Lite Extension board for the Raspberry Pi Monitoring, teaching, simple automation projects, prototyping, or application development
Unipi Neuron Programmable logic controller, Raspberry Pi, external microSD card A wide range of automation projects, from remote monitoring, and management, smart home control, and sensorics to SCADA or HVAC control systems
Unipi Patron Programmable logic controller, NXP i.MX 8M Mini (Unipi Zulu), internal eMMC memory Industrial automation or other demanding applications (deployment in SCADA systems, photovoltaics, etc.)
Unipi Gate Programmable Linux IoT gateway, quad-core processor ARM A53 Industrial automation, HVAC control systems, SCADA and MES systems, edge/cloud computing, IoT and IIoT or Smart City projects

You can find more information on the comparison of individual product lines in our section Hardware documentation.

Is it possible to use Neuron units without an SD card?

The Neuron product line uses a memory card as a medium for operating system files and running the entire application. Therefore, it is not possible to operate the unit without a card.

Does the discontinued Axon product line have a replacement?

The replacement for the discontinued Axon product line is the fully compatible Patron product line with the powerful NXP i.MX 8M Mini processor (4 × Arm® Cortex®-A53).

Is it possible to use Unipi Neuron units HDMI port?

For Neuron units, the HDMI port is intentionally blinded and for technical and warranty reasons we strongly recommend that you do not use it. You can find more information at this link.

Which memory card to choose for Unipi Neuron and Unipi 1.1?

For both Unipi Neuron and Unipi 1.1, we generally recommend SLC cards that have many times longer life and an extended operating temperature range than MLC or pSLC memory cards. You can read more about the differences between the types of memory cards in this article. If you do not want units with a memory card, we also offer PLCs with internal eMMC memory, e.g. Unipi Patron.


SOFTWARE

Are Unipi units sold with pre-installed software?


   Product line Pre-installed software
Unipi 1.1 and 1.1 Lite No, it is necessary to add a microSD card
Unipi Neuron No, it is necessary to add a microSD card*
Unipi Patron Yes, SW Mervis*
Unipi Gate Yes, SW Node-RED

*free license Mervis

Is it necessary to have Mervis licence for each PLC?

Yes, a license is needed for the Mervis Runtime - software running on the controller that executes control logic created in Mervis IDE. Without a license, the program works in the so-called Demo mode for 20 minutes, and then it is automatically stopped. In Demo mode, it is possible to test all functions. Demo mode can be restored by restarting the device, or the unit can be licensed and used without any restriction.
Thanks to the Demo mode, it is possible to try the Mervis Platform for free on all supported products.
For Unipi Neuron and Unipi Patron units, a Mervis license is included in the package. For Unipi 1.1, Unipi 1.1 Lite, and Unipi Gate, the license can be obtained either by purchasing the appropriate complete set or by purchasing the license as a separate product. You can find a guide to the licensing process at this link.

Do I have to use Unipi operating system images for Unipi 1.1 or Unipi Neuron, or is it possible to use Raspberry Pi OS?

No, it is not necessary to use the OS from Unipi, that is if you do not want to use Mervis.
Raspberry Pi OS can be used - see the Unipi Knowledge Base for more information.

What OS do you provide and how do they differ?

Each Unipi unit requires an operating system (OS) image to function. The Neuron, Unipi 1.1, and Unipi 1.1 Lite series have this image stored on the SD card, while the Unipi Patron units and Unipi Gate gateways have it stored in their internal eMMC memory.
The operating system is distributed in the form of an image, i.e., a large file containing all the necessary software and configuration to start and operate the unit. The OS depends on the software you want to use on the unit. Therefore, different SW solutions (Mervis, Node-RED, etc.) will each require a different OS image.
For more information on OS images, see the Unipi Knowledge Base.

How can I update Mervis?

We recommend:
  1. creating a backup of the original project by copying the whole project folder
  2. downloading the latest version of the Mervis IDE from the Unipi Knowledge Base
  3. updating the Mervis runtime (RT) on the unit via a new version of the Mervis IDE
See this article for instructions. If Mervis RT is too outdated (the skull icon is displayed in the overview), it is necessary to flash the OS image to the latest version.
