Hello,
Where I work the light curtains we use are usually just connected to an input on the plc. I know I have read here where that is not allowed. In our application where we have farely small machinery (stakers, projection welders) the plc actually bypasses the light curtain during ejecting the part. Is this legal? Is there any way to do this legally? Thanks in advance
