Slave Replacement Methods

The slave to be replaced is first disconnected from the network and then reconnected after you replace
it. Use one of the following methods to disconnect and reconnect the slave.
Method 1: Connecting and Reconnecting Specified Slaves from the Sysmac Studio
Method 2: Execute the Disconnect EtherCAT Slave and Connect EtherCAT Slave instructions.
Execute the following instructions in the user program. You can use a pushbutton or an HMI to input the
execution condition.
Function
Disconnect EtherCAT Slave
Connect EtherCAT Slave
If the EtherCAT slave to replace has backup parameters, we recommend that you use the Sysmac Stu-
dio to replace the slave. (You can specify backing up the parameters in the EtherCAT slave from the
Sysmac Studio.)
Additional Information
The disconnection and reconnection operations are not required for slaves that are disabled with
the EtherCAT Slave Enable/Disable Settings. You therefore cannot disconnect and reconnect
them from the Sysmac Studio. If you execute the disconnection and connection instructions, they
will result in errors.
