Device Addressing
The device can be addressed via Device Position Address (Auto Increment address), by Node Address
(Configured Station Address/Configured Station Alias), or by a Broadcast.
⚫
Position Addressing (Auto-Increment Addressing)
In this mode, the datagram holds the position address of the addressed slave as a negative value. Each slave
increments the address. The slave which reads the address equal zero is addressed and will execute the
appropriate command at receives.
Position Addressing should only be used during starting
up of the EtherCAT system to scan the fieldbus and
later only occasionally to detect newly attached slaves.
⚫
Node Addressing (Fixed Addressing)
The configured Station Address is assigned by the master during start
up and cannot be changed by the
EtherCAT slave. The Configured Station Alias address is stored in the ESI EEPROM. The Configured Station
Alias must be enabled by the master. The appropriate command action will be executed if Node Address
matches with either Configured Station Address or Configured Station Alias.
The slave matched to the address set at station register (0x0010) from the master by position addressing is
normally addressed in node addressing. This enables access without fail even when a device is added, the
segment topology has changed and/or the slave has been removed.
The respective slave node address is set with the dip switch at the front of the device and CoE Object dictionary
4000h. 0 - 65535 axes addresses can be set using the 8 dip switch (0x00 - 0xFF:bit7 - 0) at the front of the
device and with a set value of bit 15 – 8, previously written in the non-volatile memory (4000h:02h) inside the
device. When the alias selection (4000h:01h) is set to 1, the setting values will be written in the station alias
setting register (0x0012) in an address space after the control power has been turned ON. When the device
address has changed under the control power ON status, re-input the power to enable the change in axis address.
