• Explicit (non-cyclic) access to parameters
EtherNet/IP server port
The Ethernet interface uses the standard server port 44818 (0xAF12) for EtherNet/IP
communications, this is fixed and cannot be changed.
Parameter Update Rate
Parameters are exchanged over the network. The value exchanged over the network
must be exchanged with the drive or option parameter. The rate of data exchange differs
for drive and option destinations.
The diagram below depicts the update cycles used within the Ethernet interface. CIP
assembly mappings being exchanged with the drive will be updated at the background
task rate. This rate (Background cycles per second (S.09.008)) varies with the load on
the Ethernet interface; Easy Mode non-synchronized data exchange also takes place in
the background task.
