Has anybody experience with MODBUS to read temp sensors?

Hi Petr,
After the installation of the litte powersupply, I let run all 5 listings:
















Info via the commandline in a terminal:

rudy@lenovo:~$ ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 jan 12 09:59 usb-1a86_USB_Single_Serial_5A98056465-if00 -> ../../ttyACM0

rudy@lenovo:~$ ls -l /dev/ttyUSB*
ls: No acces to '/dev/ttyUSB*':  File or map does not exist

rudy@lenovo:~$ ls -l /dev/ttyACM*
crw-rw---- 1 root dialout 166, 0 jan 12 10:09 /dev/ttyACM0

rudy@lenovo:~$ groups
rudy adm dialout cdrom sudo dip plugdev users lpadmin sambashare

lsof /dev/ttyACM*
comment Rudy: Gives no output

Module Power:
I installed a small stabilized power supply module that can supply up to 4 amps of current.
The voltage regulated to 30.0 volts (Control: with Fluke meter)
Tested with power resistors: The voltage remained exactly at 30.0 volts.
(control with Fluke meter at the tension of 30.0 Volt).
(And the GND of the USB-RS485 adaptor is connected with the GND of the PTA8D08 module)

In the QB64PE map (between the names of the compiled files),
i see a file with this name and no extention:
COM1:9600,N,8,1,BIN,CS0,DS0
large: 897 bytes
(but I can not open this file).

Greatings,
