Figure 50: Setting the Communication Properties of a LAN
LAN Name: this can be edited, or the default name can be used. Space characters are not
permitted.
Description: an optional description of up to 255 characters can be entered for the LAN.
LAN ID: (read-only) this number identifies the LAN in the Machine Edition project.
Network Speed: the bandwidth available on the network. The default of 1Gbps can be
changed to 100Mbps.
Maximum Utilization (%): the maximum percentage of total network bandwidth that can be
used for PROFINET I/O traffic. It can be edited to any value between 10 and 80 (do not enter
the % character). Consider another network traffic when changing this parameter.
IP Range Lower Limit: the lowest IP Address for automatically assigning IP Addresses to
PROFINET Controllers and LAN devices. Default is 192.168.x.1, where x is the lowest number
not used by another LAN in the project.
IP Range Upper Limit: the highest IP Address for automatically assigning IP Addresses to
PROFINET Controllers and LAN devices. Default is 192.168.x.254, where x is the lowest
number not used by another LAN in the project.
CAUTION
If the subnet mask is improperly set, devices may be unable to communicate on the network
and might disrupt network communications. Contact your network administrator to assign
values that work with an existing network.
Subnet Mask: Mechanism that filters network communications so that they are routed only
to subnets to which they are addressed. The value defined here propagates to PROFINET
Controllers and I/O devices throughout the network.
PROFINET can only communicate to nodes in the local subnet. All nodes on the LAN must be
in the same subnet. The IP Range Lower/Upper Limits indicate the auto-assignment range.
