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)
