• Make sure the cable between each pair of devices connects an output port to an input port.
Normal communications are not possible if an output port is connected to another output port
or an input port is connected to another input port.
• You can use the Sysmac Studio to see if communications are possible for the total cable
length. Refer to the NJ-series CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No.
W505) for the confirmation procedure.
