System Architecture & Signal Flow
The 6GK5008-0BA00-1AB2 operates as a Layer 2 store-and-forward switch with an internal 1.6 Gbps switching fabric. All 8 RJ45 ports support auto-MDI/MDIX crossover detection, eliminating the need for crossover cables. The integrated fault relay (signaling contact) opens on power loss or internal fault, enabling integration with PLC digital inputs for supervisory monitoring. Typical deployment places the X008 at the machine or field level, aggregating device connections before uplink to a managed backbone switch (e.g., SCALANCE X208 or XC208).
Typical Topology: SIMATIC S7 PLC → SCALANCE X008 (6GK5008-0BA00-1AB2) → ET 200SP / Drives / HMI → Managed Backbone Switch → SCADA/DCS

Technical FAQ
Q: Is the 6GK5008-0BA00-1AB2 compatible with PROFINET IRT (Isochronous Real-Time)?
A: No. As an unmanaged switch, it supports PROFINET RT (Real-Time Class 1) but not IRT (Class 3), which requires managed switches with hardware timestamping such as SCALANCE XC-200 or XR-500 series.
Q: Can it be used in PROFINET ring topologies?
A: No. Ring redundancy (MRP/MRPD) requires managed switches. The X008 is suitable for star and line topologies only.
Q: What is the MAC address table size?
A: The X008 supports a MAC address table of 1,024 entries, sufficient for typical machine-level segments.
Q: Does it support SNMP or web-based management?
A: No management interface is provided. For SNMP/web management, consider SCALANCE X208 (6GK5208-0BA00-2AB2).
Q: What is the replacement/successor model?
A: The SCALANCE XB008 (6GK5008-0BA10-1AB2) is the current-generation successor with identical port count and improved diagnostics LED layout.
