The broadcast address is part of the IP protocol used by a host to send
messages to every IP address on the link. This field in the channel 2
configuration screen identifies the address on which the module will receive
broadcast messages sent by a host.

IMPORTANT
If BOOTP is enabled, you can’t change any of the
advanced Ethernet communications characteristics.
IMPORTANT
The broadcast address is used only for the reception of
messages. When used in the context of Ethernet
addressing, the broadcast function does not refer to
ladder-logic messaging.
This function does not allow for sending one message to
multiple PLC-5E controllers at the same time.
