Leuze electronic presents a genuine innovation with the new DDLS 500 data transmission photoelectric sensor: all relevant data of the DDLS 500 can be called up using remote diagnostics. The data transmission photoelectric sensor links Ethernet networks using optical data transmission with a bandwidth of 100Mbits/s and is thus part of the central network component. The devices transmit all common Ethernet protocols such as PROFINET, Ethernet IP, EtherCAT, Ethernet TCP/IP or Ethernet UDP in real time up to a distance of 200 m. For quick and simple on-site diagnostics, the DDLS 500 has a status LED visible from afar for displaying warnings and errors. This makes simple maintenance and diagnostics possible. Through the modular basic design, the devices can be arranged flexibly and depending on needs regarding operating range, remote diagnostics options, heating as well as an integrated laser alignment aid. An integrated level and the pre-mounted mounting plate with spring-loaded wobble elements make alignment simple and only require one person. Leuze electronic holds the patent for this single-hand adjustment process. All warning messages which may signal an interruption of the transfer are displayed in real-time and in the DDLS 548i version, actively transferred to the control using process data as a Profinet participant.
