    • RE: Relay sharing common "COM"

      Hi Gabriel,

      You can find most of the information in the articles on inputs and outputs in the products section on our KnowledgeBase.

      Below you will find the answers to your questions:


      What are the use cases of these relays? Is it dangerous to use these common relays with outputs having different power supplies?

      • It depends on the specific circuit connection, but in most cases such a connection is undesirable.

      Finally, is it recommended for safety reason to use a different power source between the unipi power supply and the dry contact equipment (in input) ?

      • Yes

    • RE: Digital output problem

      Hi Tad,

      When making a complaint or repair, follow the complaint procedure: https://www.unipi.technology/return

      In this case, however, it may not be a faulty HW, but only an inappropriate output setting:

      • The digital outputs on the Unipi units also enable the so-called PWM mode, where the output is controlled in a different way than during normal on / off switching.
      • Another function that could affect the outputs in this way is the so-called DirectSwitch function.

      If you work in Mervis SW, you can upload the default configuration simply by creating a new project in the Mervis IDE, assigning a PLC and uploading the Unipi module configuration.

      For other SW solutions, I recommend checking the values in the Modbus registers.

      • To check that PWM is off, check registers 16 to 19, all of which should contain a value of 0.
      • To check that the DirectSwitch function is turned off, check register 1014, it should also contain the value 0.

    • RE: xS11 Direct switch

      Dobrý den,

      váš předchozí příspěvek prověřím a případně doplním.

      Na aktuální otázku je odpověď: ANO, lze funce I/O nastavit i jinak
      Pro nastavení u rozšiřujících modulů Unipi můžete použít např. program mbpoll v linuxu (po připojení přes SSH) a komunikovat se zařízením přes modbus, kde si jednotlivé funkce nastavíte dle modbus tabulky.

      Přeji hezký den

    • RE: Oživení starého projektu - chybí DS2408_sh_trans

      Dobrý den,

      licence je skutečně vyžadována až od verze IDE 2.3.0. Ve verzi IDE 2.2.0 se sice zobrazí stav "Nezalicencováno", ale jedná se jen o přípravu.

      Doporučuji přejít na nejnovější verzi IDE 2.4.1, která má lépe řešenu práci s úložištěm a nedochází tak při správném nastavení k upisování SD karet, nebo eMMC úložiště (u vyšších řad PLC).

      Licenci Mervis je možné zakoupit na našem e-shopu.

      Transformaci DS2408_sh_trans nahraďte za lib.Unipi.ds2408_sh_trans. Jsou totožné.

      Přeji hezký den,
      Antonín

    • RE: Raspberry GPIO free with UNIPI 1.1

      Hello Fabio,

      You can select the EMO-R8 module to expand the Unipi 1.1 board with another 8 relays. This module communicates via I2C, as does the relay on the Unipi 1.1 board. Documentation for this module can be found on our KnowledgeBase.

      For communication, you can choose either direct control via I2C, or use our EVOK API, which allows you to control, for example, via the REST API or WebSocket.

      EMO-R8 connection and EVOK configuration:

      You must first set the address jumpers on the EMO-R8 and connect to Unipi 1.1 using an I2C cable. Then connect the power supplies, connect to the Unipi unit via SSH and edit the /etc/evoc.conf file. Then restart EVOK and the outputs on the EMO-R8 will be available.

      • In the /etc/evok.conf file, find the lines related to EMO-R8 and uncomment them (remove the semicolons at the beginning of the lines). Open file with administrator privileges (sudo).
        • sudo mc -e /etc/evok.conf
      • Then restart EVOK.
        • sudo systemctl restart evok.service

      Best regards,
      Antonin

    • RE: Reading the ModBus bus with the Patron

      Hello Vesa,

      Only some Patron ports are available using the deprecated /dev/extcomm/Y/X notation.
      I recommend using the ports from the table in this article: Patron serial port mapping

      To verify communication with all our Modbus devices, I recommend asking the holding register 1003, which is available for all Modbus devices Unipi and whith contains a unique identifier, according to which the device can also be recognized.

      Best regards,
      Antonin

    • RE: HMI připojení

      Dobrý den,

      email k nám bohužel nedorazil.
      Doporučuji projekt neposílat v příloze emailu, ale přes libovolnou "úschovnu" a do emailu vložte pouze odkaz ke stažení.

      Přeji hezký den,
      Antonín

    • RE: HMI připojení

      Dobrý den @Nessie,

      pokud jsem Váš dotaz pochopil správně, bavíte se o SW platformě Mervis. To co popisujete může znamenat, že v HMI máte namapovány proměnné, které ale programově nastavuje něco jiného (funkční blok, jiná proměnná, atd.).

      Typickým a jednoznačným příkladem je např. propojení DI_1.01 s DO_1.01 v programu a namapování DO_1.01 v HMI. Pokud se budete snažit změnit hodnotu DO z HMI, bude se stále vracet na původní stav, protože je s každým cyklem programu přepisována hodnotou DI.

      Pokud se Vám nepodaří chybu objevit, pošlete celý projekt v archivu spolu s krátkým popisem konkrétních problémů k nám na email: support@unipi.technology

      Přeji hezký den,
      Antonín

    • RE: Checking internet connection within mervis

      Hello,

      Currently, the best way is to find out the availability of the Internet connection in the OS and then write this information to the ModbusTCP server. You can create a ModbusTCP server directly in the OS as a separate program or define it in Mervis.

      The subsequent logic for switching the relay on/off is already simple.

      Best regards,
      Antonin
