The SIMATIC PN / AS-i F-Links facilitate the connection of AS-i (ASIsafe) networks and their connected actuators and sensors to PROFINET-based (PROFIsafe) safety controls. The exchange of standard and safe data is realized completely transparently towards both directions. Up to 62 standard slaves or up to 31 safe AS-i slaves can be connected to each AS-i network. The PN / AS-i F-Links can be scaled in accordance with the quantity structures required for the application. They support the connection of one or multiple AS-i networks.
