A wireless IO-link communication network has a main master and at least one device which have a bidirectional wireless communication between the main master and the at least one device, as well as a backup master which is connected to the main master and the at least one device and is configured to control the at least one device. In a method for operating the IOLW communication network with such a backup master, the backup master controls the at least one device instead of the main master.

Wireless IO-link communication network having an additional master and method for its operation

Equipment for the wireless operation of IO-link devices in an IO-link communication network, including an IO-link master connected to a fieldbus a wire-bonded communication network and at least one wirelessly communicating IO-link device, has a wire-bonded IO-link device serving as a wireless IO-link device interface for the wireless communication with the at least one wirelessly communicating IO-link device.

Equipment and method for the wireless operation of an IO-link communication system

Apparatus for securely transmitting data between a mobile subscriber () having at least one transmission apparatus () and a stationary receiver (), wherein the mobile subscriber () can change between a plurality of radio cells (Cell, Cell, Cell) and each radio cell (Cell, Cell, Cell) has at least one transmission apparatus (AP, AP, AP), wherein the at least one transmission apparatus (APto AP) is also connected in a wired manner to at least one network (LAN A, LAN B), wherein the stationary receiver () is likewise connected in a wired manner to the at least one network (LAN A, LAN B), and both the wireless transmission between the mobile subscriber () and the transmission apparatus (APto AP) respectively associated with the latter and the wired data transmission between the transmission apparatus (APto AP) and the at least one associated network (LAN A, LAN B) are carried out redundantly, and the stationary receiver () is redundantly connected in a wired manner to the network (LAN A, LAN B).
