Hey,

I want to test out controlling the unipi via Modbus TCP.
Got accessing the Neuron working, but how do i access the Extension Modules?
I have 1 xS11 connected to the Neuron, how can i read it's inputs and set the relays?

I could only find the normal Modbus mapping of the xS11.
My guess would be that i have to offset them??
How does it work when adding a second Extension Module?

Im just getting startet using the EVOK API over Websocket.
My first steps in controlling some Stuff worked pretty good.
Now i have the question, how to handle a crash of my control Software?
For example I use the Unipi to control a conveyor belt.
When i set the output for driving the belt high and the software is terminated the pin is of course still high.
How do you handle stuff like this, so the conveyor is stopped?

Seems like the problem was a bad Connection or so.
Testet something else and had to reconnect the rs485 wires and now it works.
Bit weird that mbpoll worked without a problem...

Hello,

i want to read Sensor Data and Control a Stepper connected to an Arduino via Modbus.
Currently only a photoelectric barrier is connected to the Arduino.
The Slave Id for the Arduino is 10 and the Address for the barrier is 99.
Successfully testet the communication using mbpoll like so:
mbpoll -a 10 -b 9600 -P none -t 1 -r 100 -c 1 /dev/extcomm/0/0

Followed this Tutorial: https://www.unipi.technology/news/plc-programming-3-working-with-external-peripherals-using-modbus-360
My Modbus Read Node does only show "reconnecting after 1000 msec."

Hopefully someone can help me as this is my first Project with Node-RED and Modbus
