  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

  Hi @dealah-in-kóma, there are basically two ways of achieving that. Both of them require connecting the Inepro energy meter via RS485. The difference is in who will be responsible for polling the Modbus data from the device. The Evok way Evok can be configured in a way, that it will poll general Modbus devices. See https://github.com/UniPiTechnology/evok/blob/master/etc/hw_definitions/CUSTOM MODBUS DEVICE.yaml The updated data are available via standard Evok API. The Node-RED way You can poll the Modbus device in Node-RED directly via node-red-contrib-modbus https://www.npmjs.com/package/node-red-contrib-modbus Personally, I would suggest you the option 2, since configuration in Evok is not easy. For configuration you need a Modbus registers map for the given device, that can be found in the documentation from the vendor. Please note, that there are several HW and SW revisions for the device and you need to use the correct documentation. The latest one is here: https://ineprometering.com/wp-content/uploads/2019/04/PRO380-user-manual-V2.18v6.pdf and the Modbus registers map starts from page 27. 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

  Hi @knebb, there are two approaches and you figured out both of them: Do the calculation and write to register 2 Write a value to the register 3000. The value has to be 32bit signed integer. I checked the documentation and I think there is a mistake with the registers 3000, 3001 and 3002. Those should be 3000, 3002 and 3004 since the 32bit values need two consecutive registers. I will check what is in the firmware and let you know! Best regards, Martin

  @ntd said in Internal ModBUS problem: I will update this thread when I will have some news. Well, I installed the new SD card a couple of months ago and received no complaints ever since, so I suppose this update solved the problem. @Martin-Kudláček: thanks again for your support .
