(3) Comparison of the RAS functions
*1: On the CC-Link IE Controller Network board, the own station is in the disconnected status between
PC start-up (power-ON) and CC-Link IE Controller Network board driver start-up. (Loopback
occurs.) After CC-Link IE Controller Network board driver start-up, a connection returns and
normal data link is established.
On the MELSECNET/H board, after PC start-up (power-ON), normal data link is continued without
executing loopback at other stations.
