Sequential Muting of a Light Curtain with S7-1500

So-called “muting” is used to distinguish if the protective field is violated by the transport of workpieces or by other reasons. Muting is the intentional suppression of the protective function of light curtains
- the light curtain is “muted” temporarily. For this purpose, muting sensors are installed on both sides of the light curtain which determine in which cases to activate muting. This allows transporting workpieces out of the work area without interrupting the production flow and at the same time monitoring access to the hazard area.

Sequential muting with 4 muting sensors (2 sensor pairs) is implemented in the application example. Photoelectric retro-reflective sensors are used as muting sensors.
