The network/serial communications configuration of a PLC other than the one originally
connected to online to can be set as the target. The PLC that was originally connected to
online (called the relay PLC, see note 1), is relayed through to connect to another PLC
(called the target PLC, see note 2) to switch the online connection.
Note 1: The relay PLC is the PLC to which an online connection was first made from the computer
through a network or serial connection.
Note 2: The target PLC is the PLC from which the network configuration can be uploaded.
