Error 15 27/01/2015 23:23:48 551 ms | 'TwinCAT System' (10000): Sending ams command >> Init4\RTime: Start Interrupt: Ticker started >> Ads error: 4115 (0x1013, RTIME: system clock setup fails.

Hint: On Windows8 system execute win8settick.bat in TwinCAT\3.1\System as administrator and reboot.) << failed!

Solution: Go to TwinCaT folder in C drive, TwinCaT>3.1>system, run win8settick.bat as administrator, and restart the computer.

Note: if the same error is reported after restart, run it several times and restart. That’s how I restarted it twice.
