  Ah, well. No I am absolutely fine with this.

  My Cacti monitors the system every 5 minutes. So no need for faster- I am fine with a minute.

  Thanks again!

  Oh, and it is working stable. Now running for nearly 2days without a reboot.

  Unfortunately the timing is too quick to be done by anything but a direct line to the CPU (Raspberry Pi/Arduino GPIOs are such a line to the CPU, which is why it works at all). As such it's not possible to use with Neuron or UniPi 1.1 out of the box. With some warranty-voiding modifications it may be possible to connect the device to an unused RPi GPIO, but I cannot recommend this action unless you are fully comfortable taking the risk and voiding the warranty. I also cannot provide instructions on doing so.

  There should be, but if there isn't you can create it. As you say there isn't, you will need to create it.

  Do note that with standard Raspbian you will need to use /dev/extcomm/ instead, and will not be able to natively change the parity settings without going through Modbus.

  @Vesa-Kauppinen No, you have to use converter. @Vesa-Kauppinen I have seen this one http://www.a2s.pl/en/mbus10-rs485-p-7941.html but have not tried it... It should not be expensive and it can handle up to 10 units on the bus.

  PWM with Neuron (M103)?

  @knebb Instead of GPIOs, Neurons use other CPUs connected to SPI which take care of I/Os (https://www.unipi.technology/upload/produkty/neuron technologický popis/NeuronExplanation%402x.png). If you need PWM, then it can be enabled for Digital Outputs (currently only 4 at each Neuron model).

  The easies way to set this up in C is to use the SysFS acces to I/Os which is available in the latest Opensource beta release of image, documentation available here: http://git.unipi.technology:3000/UniPi/neuron-kernel/src/master/docs/sysfs-platform-unipi.txt

  Or you can always use Evok or Modbus TCP whichever suits you best.

  You should be able to use the instructions in chapter 4.5 of the manual I have sent you via a private message.

  Basicly I would like to find a product which is able to receive information from Fibaro sensors and with some bolean variables I would like to set lights etc ...

  Do you have any conpatibility with wirless sensor because I don't want to use Pt100 (which will be very compicated to change if they are broken) for exemple those Fibaro Motion Sensor FGMS-001-ZW5 are detecting the motion, temperature and luminisity, and my goal is the combine philips Hue led, Fibaro sensor and your Uni-pi device . But if you have your own products or partern compatible I will like to have your point of view .

  Neuron is capable of preserving variable state using the MMC drive. Unfortunately I do not know whether the current CODESYS implementation makes use of this functionality, though I do not believe so. The CODESYS subforum may be able to provide a better answer.

  In the Axon series we have implemented better means for storing internal state, with fast flash memory used for counters and a replacement for the somewhat lacklucstre MMC arrangement on Neuron. This product line is however still in development, and will be for the next couple of months.

  @mikeardy The IP address should be changed in /etc/network/interfaces

  @tvleminc If you have a Neuron extension, just connect the RS485 of Loxone to the Extension, configure the RS485 baudrate, parity and Modbus address and just map the Registers/Coils from the Modbus registers map of the extension which is available to download here https://www.unipi.technology/helpcenter/download/

  I2C connections to UniPi Neuron

  Hello @VariableEmployee,

  I2C is not designed to run on long lines - so theoretically you can connect 30 devices if the addresses do not collide but it is not a good idea to do it like this due to the long wires.

  Also, there is no direct access to the I2C on Neurons, it is available only on UniPi 1.

  If you want to use it as a PLC, meant as a robust and reliable automation controller, I suggest connecting the peripherals via RS485...

  UART is also a low-level interface (such as I2C), in installation cabinets, these kinds of protocols is used only for the communication within one device. Protocols like RS485, RS232 and others are used to communicate with other devices.
