@tomas_hora is there a solution for a jessie installation now? We based out Software on jessie. Is there a way to get it running?

@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?

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

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

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
mauri
