Page 6: General Information
With the DDLS 200 Series, Leuze electronic offers optical, high-performance data transmission sys- tems. The data transmission units are robust and are not subject to wear. A DDLS 200 data transmission system consists of a set of two transmission and reception units: e.g. DDLS 200/200.1-10 and DDLS 200/200.2-10. -
Page 7: Operating Principle
• Minimum transmission times (real-time capable) • Deterministic transmission The DDLS 200 data transmission system, which is available in several model variations, makes pos- sible the contact-free transmission of the following bus protocols: • PROFIBUS FMS, DP, MPI, FMS - DP mixed-operation, up to max. 1.5Mbit/s, PROFISAFE •... -
