The μs tickeris a 32bit μs time counter that starts at every reboot with 0 and counts to 232-1μs. At over-flow the counter starts again with 0. With the help of the difference creation of theRETVAL results of 2 FC/SFC 53 calls before and after an application you may thus eval-uate the runtime of the application in μs.INFO1INFO2RET_VAL (Return value)VIPA SPEED7 Integrated StandardSystem Functions > FC/SFC 53 - uS_Tick - Time measurementHB00 | OPL_SP7 | Operation list | en | 18-30 689
