Using POSIX realtime

Hello everyone,

i have completed the Ethercat installation according to rodw
forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step

The installation went smoothly and the final test was positive:Component Pins:
Owner   Type  Dir         Value  Name
     4  u32   OUT    0x00000001  lcec.conf.master-count
     4  u32   OUT    0x00000004  lcec.conf.slave-count

The following version of Linuxcnc is installed:
6.1.0-30-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.124-1 (2025-01-12) x86_64 GNU/Linux

When I check if /sys/kernel/realtime exists, I get /sys/kernel/realtime
When I check the module cia 402 (halcmd loadrt cia402 count=1), I get Using POSIX realtime

Am I wrong as a layman if I assume that this is not real real time and that there may be problems with some modules?

thank you very much tommylight
