Precautions when configuring a multiple CPU system
 Set a CPU module connected to an Ethernet device as a control CPU of the Simple Motion module performing the IP packet transfer.
 Any CPU module in a relay station on CC-Link IE Field Network can be served as a control CPU of the Simple Motion module transferring the IP packet.
 When multiple Simple Motion modules or master/local modules with the same network No. are connected to one system, the Simple Motion module or the
master/local module with the smallest slot No. transfers the IP packet. To transfer the IP packet, connect the Ethernet device to a control CPU of the Simple
Motion module or the master/local module with the same network No. and smallest slot No.
