Siemens 6SL3055-0AA00-6AA1 DMC20 DRIVE-CLiQ Hub Module
An IP20 DRIVE-CLiQ hub that expands a line into a serviceable star topology inside the control cabinet.
Key Information
6SL3055-0AA00-6AA1 is the Siemens DMC20 DRIVE-CLiQ Hub Module for SINAMICS drive systems. Six DRIVE-CLiQ sockets are provided so five devices can connect while the remaining path links the hub to the line.
The hub implements a star-shaped DRIVE-CLiQ topology and can be cascaded with a second hub. Removing one connected node does not interrupt data exchange with the remaining nodes, which supports structured service of distributed drive components.
The DMC20 is an IP20 control-cabinet device. Unused interfaces require blanking covers, and every DRIVE-CLiQ component must be included in the functional equipotential-bonding concept.
Functions
DRIVE-CLiQ distribution
Collects multiple node connections and forwards them through one DRIVE-CLiQ path.
Serviceable branches
Allows an individual branch device to be removed without stopping communication to the other branches.
Status indication
Uses a multi-color LED to show hub operating state.
Cabinet integration
Mounts on a standard rail with a dedicated electronics supply and protective-conductor point.

About IndustryParts
https://www.industryparts.com/The hub is supplied with its full topology record
IndustryParts keeps the DMC20 article, branch map, node list and cabinet evidence together so a DRIVE-CLiQ expansion remains traceable.
Installation
Design the topology
Document the upstream port, five branch nodes, cable lengths and any cascaded hub before installation.
Bond and protect interfaces
Mount on bare bonded metal or provide the specified bonding conductor; cover every unused socket.
Validate each branch
Power the network, confirm the LED state and verify recognition of every DRIVE-CLiQ node without branch-address ambiguity.
Lifecycle
Port map custody
Keep the branch drawing and device serials with the drive project.
Contamination prevention
Retain blanking covers on unused DRIVE-CLiQ sockets during operation and storage.
Cable governance
Use released shielded DRIVE-CLiQ cables and preserve the approved length limits.

FAQ
How many branch devices can connect to 6SL3055-0AA00-6AA1?
The DMC20 uses six sockets to connect five DRIVE-CLiQ devices while maintaining the line connection.
Can 6SL3055-0AA00-6AA1 be installed outside the control cabinet?
No. DMC20 is the IP20 cabinet version; the DME20 is the external IP67 hub execution.
What bonding information belongs with a 6SL3055-0AA00-6AA1 installation?
Document the bare-metal mounting or parallel equipotential-bonding conductor for every distributed DRIVE-CLiQ component.
Can two 6SL3055-0AA00-6AA1 hubs be cascaded?
Yes, Siemens documents a two-hub cascade, but the complete approved topology and cable limits must be retained.
What should be tested after replacing 6SL3055-0AA00-6AA1?
Confirm supply voltage, LED state, every branch device, unaffected-node communication and the restored topology record.
