HSC_HSC_Period - How can reset it ?

#dP

Hello.

The S7-1200 from firmware V4.2 we are encouraged to use the CTRL_HSC_EXT function instead of the CTRL_HSC instruction. The functionality of CTRL_HSC_EXT was expanded for this firmware version and TIA V14; looking different than TIA V13.

The documentation in the TIA Portal help ("Information system") for

CTRL_HSC_EXT:
Control high-speed counter (extended) 

lacks very much of the detail. Luckily the detail is mentioned in full in the PLC manual A5E02486680-AK.

It would be nice to have the full description of CTRL_HSC_EXT (and associated data structure like HSC_Count) inside TIA Portal.

TIA

 I am using a HSC_HSC_Period .. how can i reset it ?
