Simplified configuration of "QuickConnect" at the bus node
CPX-FB36:
Set the CPX parameter "IP configuration" to "with saved
•
parameters and QuickConnect".
With activation of "QuickConnect", the "Crossover" detection
is deactivated for both network connections. As a result, con­
nection X1 runs in the MDI-mode and connection X2 runs in
the MDI-X mode.
This allows a line topology to be constructed with patch
cables:

The bus node corresponds to a "Class A device" in accord­
ance with the EtherNet/IP specification. When switched on,
the bus node requires less than 350 ms to accept a TCP con­
nection. Due to the rapid establishment of the TCP connec­
tion, the detection of already used IP addresses (ACD, "IP Ad­
dress Conflict Detection") is not executed completely.
Multiple assigned IP addresses are only detected late. As a
result, the network can be disturbed.
If IP addresses are correctly assigned in the network, de­
•
activate the ACD via attribute 10 of the TCP/IP interface
object (è C.2.3).
