  Hello @juergen, please send the serial number of your L403 to support@unipi.technology. I'll check what firmware you might be running. Thank you and have a nice day, Martin

  Hello @sawit. The DIP switch marked as RS485-END enables a 120ohm termination resistor between the RS485A and RS485B. The ModbusTCP server running on the PLC is for accessing local IOs, not for accessing anything else over RS485 The RS485 are available as standard devices /dev/ttyNS0, /dev/ttyNS1 and /dev/ttyNS2. To access any serial device over this line, you need to use ModbusRTU getter in Node-RED. Alternatively, you could define ModbusRTU device in the Evok directly, but that's quite complicated. Try the Node-RED way first. Best regards, Martin

  Hello Martin, At this moment i got everything working good with BACnet/IP. It is working very fast. All the buttons are (except the dimmer function) connected to the relay outputs, Now i need to programm a dimmer on de M203. I want to use the AO for 1-10 volts to regulate a led dimmer module. I need to find that out, never did that before. Thanks for your help.

  Dobrý den, modul JA-121T s UniPi propojit lze. Na straně RS485 máte celkem 4 kontakty, kde D+ je myšleno jako A a D- jako B. Svorky U+, GND jsou určeny pro napájení oddělené části čipu s RS485. Podle letáku JA-121T (zde) lze zjistit, že napětí mezi svorkami U+ a GND může být v rozsahu 6-28 VDC, můžete proto použít napájení 24 VDC určené pro jednotku Unipi. Spotřeba je 15mA. Pokud chcete použít kabel se stíněním, uzemněte jej na straně PLC. Modul JA-121T není modbus zařízení a proto zatím není integrován v Mervis IDE. Na vývoji se pracuje.

  Zdravím ve spolek ;) Aktuálně jsem se zabýval komunikací elektroměru EM 340, která mě také trochu potrápila, ale nakonec je vše funkční. Zásadním problémem je pořadí bytů! Není 12345678 jak je uvedeno v ilustracích této diskuse výše. Pořadí MultiByte (Parser) je 3412. Přikládám několik obrázků jako stručný návod pro nastavení. Ve stejném smyslu lze nastavit vyčítání ostatních proměnných. Vyčítané proměnné z EM340: Nastavení skupiny - Read_VAL (počáteční prvek a počet): Nastavení prvku - L1_A: Nastavení prvku - L1_W:

  Dobry den, je to tak ako uvadzate, problem sa prejavuje odvtedy, ako sme zacali PLC ovladat stykace ktorymi ovladame elektricke vykurovanie celeho domu a kvoli tomu sme natiahli v blizkosti teplomeru viacere vodice, cez ktore v spicke prechadza aj 14kW. Dakujem za rychlu odpoved a navrhnute riesenie, ktore nam pomohlo.

  Dobrý den @lukasvitek911, relé jsou Fujitsu F3AA024E, zde je výtah z datasheetu: DO jsou na většině jednotkách a vždy v počtu 4 kusů. Jsou typu NPN, tedy na jejich výstupu není 24V. Spíše bych Vám doporučil poohlédnout se po nějakém Modbus rozšíření, který má patřičný počet PNP výstupů. S pozdravem, Martin

  Well @nicola-mondinelli, you should submit it to the manufacturer of the Raspberry Pi. We buy stock Raspberry Pis just like everyone else. Best regards, Martin

  Thanks a lot. I am planning some extensions to my system, so I might want to use the discount you promised :) Btw, any reason why DI/DO lines are registered as separate GPIO chips, instead of using a smaller number of chips each with 16/14 lines?

  I have a similar for my Neuron L303. I didn't check via Mervis, but I just noticed that the indicator LEDs on the unipi itself was not reacting in any way anymore for some specific DI (others still working). Do you think this is due to the same firmware issue or a more fundamental hardware issue? And why would I only have this issue now? I have only been running my unipi for some debugging purposes up until now (it's just when experimenting with my actual full set of push buttons that I started to notice this).

  @stephane-clavel Do the RUN leds blink? Did you save the direct switch configuration to NV ram or do you set ip up again after boot? Can you provide the output of i2cdetect -y 1 ?

  Hello @asunc, absolutely no problem. The Axon is running a debootstraped arm64 Debian with added repository of our packages via which we publish fixes and new versions of our software. Best regards, Martin

  The issue was by the incorrect comm speed with the modem. I modified the guide provided by @roberts_lando to use the proper baudrate of 9600 instead of 115200.

  @barnabás-králik said in About the relays: I'm thinking about using an L403 for controlling a large number of blinds (apart from other building automation duties) with 2 relays per blind motor. Why not go for TCP-IP solution, i use a Kincony kc868-h32, a 32 relay solution, that you can steer the relays true a url link command, works fine for me. There are similar solutions more hobby orientated, and more pro, over Modbus, serial and TCP-IP, there are also 2/4/8/16 solutions out there, so that you can have your relays close by what you wane control, and only have to run a network or serial cable to the relay unit. https://www.youtube.com/watch?v=RVWvRN8yKWs

  Helo @jos0, the name "holding register" doesn't mean the value is stored in the non-volatile memory. This is just a type of the data store which comes from the Modbus naming convention, which means it can be read and written into, as oppose to the Input register, which can be only read. You can save the current value of the counter register with the saving of the current values to internal flash. This save can be initiated by e.g. setting the coil named "Save current configuration and use on startup" which has to be called on the appropriate group. We do not recommend to do it very often as this will corrupt the internal memory. Try solving the problem in the program instead. Best regards, Martin

  Hi @knebb, definitely not. The DOs are NPN type (open collector). You can read more about how to read the NPN outputs with digital inputs here: https://forum.unipi.technology/topic/712/neuron-12v-digital-input/2 Best regards, Martin
