5.11 Characteristic Data of the Integrated 4−Port Switch
Learning addresses / deleting addresses (aging time)
The 4-port switch integrated in the CP automatically learns the addresses of the
DTEs connected via a port by evaluating the source addresses in the data
packets. If the switch receives a data packet, it directs this packet only to the port
via which the appropriate DTE can be obtained.
The switch monitors the age of the learned addresses. Addresses that exceed the
“aging time” are deleted.
The aging time set on the CP 443-1 Advanced is 5 minutes.
Ports can be deactivated individually
The individual ports of the 4−port switch integrated in the CP can be deactivated in
STEP 7 / HW Config. This can, for example, be used for service purposes.
The port is turned off completely when it is deactivated. The LINK and RX/TX
LEDs are turned off.
