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 PNCs 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. The range of the LAN is the subnet mask range. A node can be assigned to any
address in the subnet (which may be outside of the auto-assignment range given in the
dialog), but the addresses for all nodes must be in the subnet.
Gateway: The IP Address of the device that connects two (sub) networks that use different
communications protocols, enabling them to communicate with each other. The value defined
here propagates to PNCs and I/O devices throughout the network.
IO-Controllers: (Read-only.) The number of I/O Controllers configured to reside on the LAN.
IO-Devices: (Read-only.) The number of I/O devices configured to reside on the LAN.

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.
