MP377 Cycle Time

AlecTek Posts: 95 Rating: (0)	Can any expert tell me if my cycle time is too much (over HMI Enable Time)? And what could be done to decrease the cycle time? Except OB1, OB32 to OB35, is there any other possible entrance for program to run? In fact my program has only OB1 and OB35. Thanks in advance!

Cycle Time = OB1 execution time + HMI Enable Time You can find more information about HMI Enable Time in the following manual on the chapter 5.3.8. SIMATIC WinAC MP 2008 The default of HMI Enable Time is 50 ms. You must check screen change and refresh time during operation of the panel. You can decrease the HMI Enable Time, if the screen change and refresh time during operation of the panel is ok. See the chapter 5.3.9. Tweety
