PROFIBUS / RS 485
Leuze electronic DDLS 200 21
TNT 35/7-24V
5 PROFIBUS / RS 485
The PROFIBUS model of the DDLS 200 has the following features:
• Operating ranges 30m, 80m, 120m, 200m, 300m, 500m
• Electrically isolated interface
• The DDLS 200 does not occupy a PROFIBUS address
• Integrated repeater function (signal processing), can be switched off
• Protocol-independent data transmission, i.e. transmission of the FMS, DP, MPI,
FMS/DP mixed operation protocols, PROFISAFE
• 2 connection variants: clamp connection with screwed cable glands or M12 connectors
• Connectable bus terminator (termination), or ext. terminator plug on the M12 model
• 6 baud rates configurable (see Chapter 5.3)
• Optional M12 connector set for conversion available as accessory
• Cascading of several DDLS 200 is possible (see Chapter 4.3)
5.1 PROFIBUS connection - devices with screwed cable glands and terminals
The electrical connection to the PROFIBUS is made at the terminals A, B, and COM. The terminals
A’, B’ and COM are provided for wiring through the bus.
