*1. The communication unit is compatible with EtherCAT type E3NW-ECT and E3NW-CCL of CC-Link. This unit is not usable
      with E3NW-CRT.
*2. Channel 1 of each amplifier unit is output as the output drawn by the cord.
*3. Output signals from two sensors are assigned to the PLC via the network. Various settings can be changed and detected
      values can be read by operating the PLC via the network.
*4. This is the case of connecting with OMRON NJ series. For details, refer to the communication unit manual.
*5. The bank is not reset by the user reset function or saved by the user save function.
*6. Only E9NC-VA0/AA0 is able to connect to between 17 and 30 units.
