2-2 Setting the Node Addresses of the
EtherCAT Slaves
This section describes the procedure to set the node addresses of EtherCAT slaves.
There are methods to set a node address with hardware switches or the Sysmac Studio.
Additional Information
• The hardware switch setting is read only once when the power is turned ON. Even if the set-
ting is changed after the power supply is turned ON, the new setting will not be used until the
next time that power is turned ON.
• If same node address is set for more than one node, a Slave Node Address Duplicated Error
(24200000 hex) event occurs.
For the operation of slaves when the event occurs, refer to the description of each event in
Errors in the EtherCAT Master Function Module in the NJ/NX-series Troubleshooting Manual
(Cat. No. W503) .
• If you use an OMRON EtherCAT slave, after setting the node address, you need to cycle the
power supply to the slave to apply the setting.
2-2-1 Setting Node Address Using Hardware Switches
For slaves with hardware switches, you can set the node address using only the hardware switches,
instead of using the Sysmac Studio.
This section describes the node address setting with two hardware switches using an OMRON GX-
series Remote I/O Terminal as an example below.
The 10s digit is set using the left rotary switch and the 1s digit is set using the right rotary switch.
The setting range is from 00 to 99.
