6 Basic Specifications of Slave Units
6 - 6
GX-series EtherCAT Slave Unit User’s Manual
These switches are used to set node addresses of Slave Units in the EtherCAT network (decimal).
Set the tens digit of the node address on the left switch and the ones digit on the right switch.
Setting range is 00 to 99. (Default setting: 00)
Note that the node address set values vary as shown below when the EtherCAT Master Unit is made by
OMRON or by other manufacturers.
Precautions for Correct Use
• The setting on the node address switches is read only once when the power is turned ON.
Even if the settings are changed after turning the power supply ON, they are not reflected in
the control. They become effective when the power supply is turned ON the next time.
• If node addresses overlap, an error occurs and the operation stops.
• If you set the node address switches to 00, the Slave Unit will not operate if the node address
setting made from the Configuration Tool is not changed from 0 to another value. If the node
address switches are set to 00, always use the Configuration Tool to change the node address
to a value between 1 and 65,535.
• The code printed above the node address setting switches differs according to the unit version
of the Digital I/O Slave Unit, Analog I/O Slave Unit, or Encoder Input Slave Unit, as shown
below.
