问题
I was trying to activate my configuration on my local PC, but it failed. I tried:
- Isolate 1 or 2 cores on my pc (Under SYSTEM > Real-Time and reboot the PC) and run the PLC tasks on those cores. When I do this I get the following error:
'TwinCAT System' (10000): Sending ams command >> Init4\RTime: Start Interrupt: Ticker started >> AdsWarning: 4118 (0x1016, RTIME: startup of isolated CPU fails!) << failed!
- I then tried to run it on the normal windows dedicated CPUs (so none of the CPU’s were isolated). When I activated the configuration (and enabled Virtualization in the BIOS) I got the following error message:
Setting TwinCAT in Run Mode with KB4056894 is not possible
Uninstall KB4056894
or
Activate a solution using only isolated cores
I could not find KB4056894 installed on my PC. Any other solution?
I'm using TwinCAT 3 Build 4022.14 under Windows 10.

From Beckhoff support:
According to the error note, the Microsoft patch for spectre/meltdown is installed on your PC. Normally, the TC3 should work with this patch when using isolated cores…
However, since version TC3 Build 4022.16, this problem is solved.
I installed 4022.22 and everything worked.
