    • RE: Modbus RTU vs Modbus TCP

      @tomas_hora

      so as i understand:
      the UniPi can only Accessed by Modbus TCP
      the Extension only by Modbus RTC (thru /dev/extcomm/0/0)

      is that right?

    • Can't get runnig RS-485 on jessie

      Hello

      im stucking get running RS-485 on an blank raspian-jessie image, with all current updatedes.

      downloaded the https://github.com/UniPiTechnology/neuron_tcp_modbus_overlay/archive/master.zip and installed.
      /dev/extcomm/0/0 is present.
      but no data are coming out.....

      with der Uni Pi Open Source Image all is working fine, see: https://forum.unipi.technology/topic/486/modbus-rtu-vs-modbus-tcp

    • Modbus RTU vs Modbus TCP

      Hello

      i'm tring to access multiple Neuron Extensions and the Neuron S103

      xS10 on Adress 1
      xS30 on Adress 2
      xS30 on Adress 3

      I'm using the Open-Source Image "UniPian-Neuron-OS-2017-08-30.zip" and the Tool "mbpoll" from https://github.com/epsilonrt/mbpoll

      if i access to the Modbus thru RTU i see only the Extentions but not the Neuron S103

      if i access the Modbus thru TPC i see only the S103, but the Extensions. At least i don't now how to access them.
      Slave 0 and 1 are the same.

      How access to the S103 registers thru Modbus RTU?
      Now access to the Neuron Extension thru Modbus TCP?

      thanks for your help

    • evok on Neuron

      Hello

      i'm testing the Neuron S10x with the evok software.
      i installed evok, attached an 1Wire temperature sensor DS18B20, on a the evok WebInterface i see the correct temperature. so far so good.

      If i now slide the Analog Outup slider arround, nothing happens on the AO port of the Neuron. The multimeter don't show any value.

      I suppose that the /etc/evok.conf i not correct. I played arround but get no significant results.

      can you provide me e correct configuration for the neuron s10x?

      thanks
