Selection Notes

Pick the SC-port 3BD00 variant over the ST-port 3BB00 sibling to match SC fiber terminations already installed in the plant — the electrical specification and management feature set are otherwise identical. Being managed, this switch adds MRP/HRP ring redundancy, VLANs, and PROFINET IO diagnostics that the unmanaged XB004 series lacks, which matters where a ring topology needs sub-300 ms reconfiguration or where SNMP-based network monitoring is required.

Applications

Backbone or ring-topology switching for PROFINET machine networks needing redundancy, VLAN segmentation, and remote diagnostics, with multimode SC fiber uplinks between panels or cells.
