ThomasKenis Posts: 2 Rating: (0)	Hello Is it possible to cut off the power supply to a digital output card? Because I want to use a safety relais to switch of a whole card when the emergency button is pushed. The type of the cpu and the output card are s7 1511-1pn and DQ 16x24VDC/0.5A HF. Thanks a lot!

So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine
