Full wire speed switching
Number of frames per second (at 100 Mbps)
Note
The number of SCALANCE XR
-300WG modules connected in a line influences the frame
delay. When a frame passes through IE switches of the SCALANCE XR
-300WG product
line, it is delayed by the store and forward function of the device:
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 XR
-300WG product line that the frame
passes through, the longer the frame delay.
