Description
Schneider Electric 170DNT11000 Profibus DP Adaptor
Schneider Electric 170DNT11000 connects your Modicon Momentum PLC to Profibus DP networks. This compact adaptor sends data at speeds from 9.6 to 12 Mbit/s. It works with twisted pair cables in multidrop or ring layouts. Use it to link up to 126 field devices in one network.
This adaptor also integrates seamlessly with Modicon Quantum systems when used as remote I/O. The 170DNT11000 acts as a slave on the Profibus DP bus.

Frequently Asked Questions (FAQ)
Q1: Can I use 170DNT11000 with a Siemens S7-1200 PLC?
Yes, if your S7-1200 has a Profibus DP master module (like CM 1243-5).
Q2: What happens if cable length exceeds 1200 meters?
Signal becomes weak or unstable. Add a Profibus repeater to go further.
Q3: Does this adaptor need external 24V power?
Yes, the 170DNT11000 draws power from the Momentum backplane. No extra supply is needed.
Q4: Can I use 170DNT11000 in outdoor cabinets?
No. IP20 rating means indoor use only. Protect it from rain or dust.
Q5: Why does my network stop at high speed (12 Mbit/s)?
Reduce cable length or use better shielded cable. Some old devices may not run at 12 Mbit/s.
Q6: Is 170DNT11000 compatible with Modicon Quantum?
Yes, use it as a remote I/O adaptor connected to a Quantum Profibus DP master.
Selection Guide & Expert Advice
- For long networks: Choose 170DNT11000 with 1200m cable support.
- For very high speed (12 Mbit/s): Keep each segment under 100 meters.
- For legacy systems: This adaptor works with most Profibus DP masters from Siemens, ABB, or Emerson.
- For harsh vibration areas: Use locking SUB-D connectors.
- For easy commissioning: Set address switches before mounting the unit.
