@raubucs Can you share the whole project? Have you tried all of the RS485 lines?

@heikkim Hello, to enable wifi you should enable the interface in /boot/boot.cmd by commenting the followin lines (add a # at the beginning)

fdt set /soc/mmc@01c10000/bcrmf@1 status "disabled"
fdt set /soc/mmc@01c10000 status "disabled"

Then run mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr and reboot.

Does it work?

@jcmschoot what UART device? Do you have some RS485 usb converter?

@mmcreativ Unfortunately the source project is not stored on the PLC so there is no way to recover it.

@roberts_lando Evok uses the Modbus TCP interface to interact with the IOs, disabling it will cause that evok wont work.

You can disable it by calling "systemctl stop unipitcp" and "systemctl disable unipitcp".

@leif-edh That is doable but you would need to setup WiFi access point on one of those M205 (find a tutorial for hostapd), and enable bridging (available in bridge-utils package).

If you won't use static IP addresses, you would have to also setup a DHCP server on the WLAN and eth, br interfaces.

This tutorial might help you a bit: https://www.cyberciti.biz/faq/debian-ubuntu-linux-setting-wireless-access-point/

Another option is to put a router AP in the middle of it all.

Also, note that the internal wifi antenna does not have much gain and is inside an aluminum box so the range is limited...

Hello @clueless ,

yes the delay switches are non-blocking for the rest of your program.

If you have Neuron or Axon that is already prepared in the HW and available in Mervis as a OW_off variable. If you set it to true, the whole bus is shut down.

If you have UniPi 1 then this is a good start but note that 1wire devices are powered by the data so this reset must not be enough.

Dobrý den, @safranekj,

pokud opravdu nechcete aby se funkce LT vykonavala pri kazdem cyklu, doporucuji opravdu pouzit na vstup en funkce LT vystup z PulseGenerator. Jen pozor na to, ze ikdzy funkce LT bude mit en na False, stale bude mit na vystupu defaultni hodnotu.

@matt The standard wpa_supplicant tools works well.

@stonefieldlab Thanks! Will fix that :)
