Using Broadcast Addressing

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

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.
