Is this short STL code correct ?

ON "Alarm WZI Actief"
O "Reset Vanaf de WZI"
FN M 21.1
R C 10


If "Alarm WZI Actief" becomes low or "Reset Vanaf de WZI" becomes high, then reset Counter C10 to zero.

?

I would do this

AN "Alarm WZI Actief"
O "Reset Vanaf de WZI"
FN M 21.1
R C 10

Otherwise if "Alarm WZI Actief" was on and "Reset Vanaf de WZI" was off, you may still reset, as the RLO could be anything at the start, if it is '1', then the ON "Alarm WZI Actief" will allow the RLO to remain on and you would reset at the incorrect time.

hey

I understand

thanks

This is the complete code

AN "Alarm WZI Actief"
AN "Alarm WZI -- Bel"
FP M 21.0
CU C 10

L C 10
L 2
>=I
= "Meer dan 1 WZI Alarm"

AN "Alarm WZI Actief"
O "Reset Vanaf de WZI"
FN M 21.1
R C 10

If I had used ON instead of AN, Reset would've been done when "Meer dan 1 WZI Alarm" came 1. Because the RLO is 1 from there. Therefore it's better to use AN.

I understand,

Thanks man
