Wireless and machine safety really can go hand in hand. One Siemens' customer, CAMotion, recently delivered wireless safety system as part of the control system it supplied for a gantry crane. The system connects the safety devices on the crane's moving gantry — including light curtains — back to the system's stationary controller. "It's the first wireless safety system that we're aware of," says Bryant. Why wireless? Hard-wiring the safety systems would have been difficult given the crane's layout. Bryant estimates that the wireless system cost about 60 percent less to install than a comparable wired system. Bryant adds that Siemens' PROFINet and PROFISafe safety communications protocol can run over wireless networks, making the installation possible. For more information go to CAMotion.
