Hi,

I'm using the HSC 1 (Inputs: 0.0 and 0.1) to count pulses from an encoder (this works).

The problem:  I can't reset the counter.

I use the CTRL_HSC -block with:    - a pulse on 'CV'
                                                    - a DInt-value (=0), from a Datablock,  at 'NEW_CV'
                                                    - I have put a 1 at 'EN' too (but this shouldn't be necessary)

Extra information:
PLC S7-1200   CPU 1214C   (firmware v1.0)
TIA Portal v10.5 SP2
Settings of the HSC:      Counting ; AB Quadrature 1X ; Initial counter/reference value = 0.
I can't use the external reset, because I need that input for another counter (which I can't reset either)

Is there something I'm missing?

Thank you for your help.
