Note
The number of IE switches of the SCALANCE XB-000 product line connected in a line influences
the frame delay.
When a frame passes through IE switches of the SCALANCE XB‑000 product line, it is delayed by
the store and forward function of the switch
• with a 64 byte frame length by approx. 10 microseconds (at 100 Mbps)
• with a 1500 byte frame length by approx. 130 microseconds (at 100 Mbps)
This means the more devices of the SCALANCE XB‑000 product line that the frame passes
through, the longer the frame propagation time.
Hardware version
You will find the hardware version of your device on the type plate. On the type plate, the
hardware version is printed as a placeholder “X”.
Example: X 2 3 4 5 6
In this case, "X" would be the placeholder for hardware version 1.
