Features of the DDLS 200
The fact that bus systems are found in nearly all areas of industry places high demands on data trans-
mission systems. The DDLS 200 fulfills these requirements, particularly with regard to:
• Transmission safety
• Minimum transmission times (real-time capable)
• Deterministic transmission
The DDLS 200 data transmission system, which is available in several model variations, enables the
contactless transmission of the following bus protocols:
• PROFIBUS FMS, DP, MPI, FMS - DP mixed operation, up to max. 1.5MBit/s, PROFISAFE
• INTERBUS 500kBit/s, RS 422 general, copper conductor
• INTERBUS 2MBit/s / 500kBit/s, fiber-optic cable
• Data Highway + (DH+) from Rockwell Automation (Allen Bradley)
• Remote I/O (RIO) from Rockwell Automation (Allen Bradley)
• DeviceNet
• CANopen
• Ethernet for all protocols based on TCP/IP or UDP
Other bus systems on request.
1.4 Operating principle
To prevent the devices from mutually interfering with one another during data transmission in duplex
operation, they use two different frequency pairs. These are indicated by the type designation ….1
and ….2 as well as the label frequency f
1
and frequency f
2
on the control panel.
Figure 1.1:Operating principle
The received signal level is checked at both devices and can be read on a bar graph LED indicator. If
the received signal level drops below a certain value, e.g. due to increased soiling of the optics, a
warning output is activated.
All work on the device (mounting, connecting, aligning, indicators and operational controls) is per-
formed comfortably on the front of the device.
