FINS commands are transmitted across networks and to various devices (via
network nodes). Designate the addresses as follows:
• Designate the device from which the command is to be sent, the network
that the device is on, and the node through which the command is to tran-
sit.
• Designate the device to which the command is to be sent, the network the
device is on, and the node through which command is to transit.
Addresses must be provided for the network, node, and device (unit) to iden-
tify them. FINS commands include these addresses (the transmission source
and destination addresses) in the command/response frames.
