S7 1200 HSC Store Value

Hello,

dose anyone know how I could store a value from a HSC for a short period of time e.g 60sec and then use this value for a calculation

Also could someone explain to me what exactly an interrupt is on a HSC?

thanks

The HSC is counting continiusly?

Use a timer to generate a pulse every 60sec.
If pulse, move the HSC IW/ID to a MW/MD or evt. a DBx.DWy/DDy.


Not knowing the 1200, I recon the interrupt from the HSC triggers an OB. In this OB you could read the HSC contents and do an action with the least possible time delay.

I have the general idea of what i require to do but am having trouble implimenting it.

I will require the HSC to reset to zero and have the value sent to a memory location. this will have to repeat continuously.

I am not sure about the "interrupt" what exactly it means. dose it just reset the counter to zero?

I think i will need the HSC Ctrl block but am not sure exactly
