Abstract: A security device to support secure communication via a field bus, has a connecting apparatus for the direct coupling of the security device to a network interface of a field bus subscriber, which is formed for connecting to a field bus and which is not formed for secure communication via the field bus. In the coupled state, there is a link between the security device and the field bus subscriber such that, if the link is disconnected or damaged, proper operation of the security device is reversibly or irreversibly blocked. Further, a transmitting and receiving apparatus is provided which is formed to securely transfer data coming from a directly coupled field bus participant, which is not formed for secure communication, via the field bus according to a predetermined security protocol, and which is further formed to receive data transferred via the field bus and intended for the field bus participant according to the predetermined security protocol and to deliver them to the field bus participant.

Abstract: Aspects herein relate to an attachable plug-type connector for attachment to a plate-like component part, in particular a device or housing wall, with an attachable housing and a contact carrier. In one implementation, the contact carrier may be arranged in the attachable housing and has at least one female or male contact in a plug-in section of the attachable plug-type connector and at least one connection element. Further, the attachable housing may have at least one plug-in stop and may include an attachable arrangement with a plate-like component part and an attachable plug-type connector.

Abstract: An attachable plug-type connector for attachment to a plate-like component part, in particular a device or housing wall, with an attachable housing and a contact carrier, which is arranged in the attachable housing and has at least one female or male contact in a plug-in section of the attachable plug-type connector and at least one connection element. The attachable housing may have at least one plug-in stop and at least one latching means for fixing the attachable plug-type connector to an edge which delimits an aperture of the plate-like component part by virtue of said attachable plug-type connector latching behind said edge, wherein this fixing of the attachable plug-type connector on the component part takes place automatically when the plug-in section is plugged into the aperture. The subject matter herein further includes an attachable arrangement with a plate-like component part and an attachable plug-type connector.
