Hi,

I want to use two OneWireMaster on a Raspberry Pi5.
I'm running Codesys Control for Raspberry Pi 64SL V 4.15.0.0.

Under Linux I've configured two GPIOs for 1w bus usage on GPIO4 and GPIO27.
Under Linux both masters seem to work fine and I can readout both sensors connected to both GPIOs.
The two masters are 'w1_bus_master1' and 'w1_bus_master2'.
In Codesys I've configured to OneWireMasters with the corresponding file paths.
But in Codesys the 2nd onewiremaster "w1_bus_master2" doesn't work.
Status is showing "OnewireMaster : Not running"

What am I doing wrong?
Does Codesys on Raspberry support multiple OneWireMasters?

Any help is appreciated.

check if the second onwire master is accessible in the configfile path setting.
/etc/codesyscontrol/

Thx for the hint.
It works if I add following line to the .cfg file.

PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$

Is there a documentation how to modify this config file?

Will this be overwritten if I do an update of the CodesysControl Runtime?

CODESYScontrol.cfg will be overwritten, CODESYSControl_Usr.cfg not.
