Siemens 6BK1620-0AA00-0AA0 PN/CAN LINK PROFINET-to-CANopen Gateway IP20 PLC Communication Module

The Siemens 6BK1620-0AA00-0AA0 SIMATIC PN/CAN LINK is a PROFINET-to-CAN gateway that bridges a PROFINET IO controller to CAN 2.0A/B or CANopen CiA 301/302 networks. It acts as CANopen Manager or Slave, runs on 24 V DC, mounts on DIN rail, and provides a 2-port PROFINET switch plus isolated 9-pin sub-D CAN interface for up to 126 devices at up to 1,000 kbit/s.

Selection Notes

Choose this module when a PROFINET IO controller needs to reach a CAN 2.0A/B or CANopen segment, since it acts as CANopen Manager or Slave rather than a passive protocol converter. Node/life-guarding, heartbeat, and SYNC services are supported, so it fits CANopen networks that rely on those monitoring mechanisms. The 2-port integrated PROFINET switch means it can sit in a line topology without an extra switch, and I&M data (I&M0 to I&M3) supports asset tracking through TIA Portal from STEP 7 V14 upward.

Applications

Used to connect legacy CAN or CANopen field devices, such as sensors, drives, or third-party controllers, into a PROFINET-based SIMATIC automation architecture without replacing the CAN-side equipment. Suited to machine retrofits where a PROFINET backbone is added but CANopen actuators or I/O stay in place, and to panel builds needing CANopen Manager functionality from a PROFINET PLC.
