Network Reset Handling
3.7.1
Reset Node
If a valid firmware has been downloaded via FoE (File access over EtherCAT), the Anybus
CompactCom 40 EtherCAT will send a reset type 00h (‘Power-on reset’) to the application at
the transition from BOOT to INIT.
Prior to the reset command a Reset_Request command has to be sent to the host application
to make sure that a reset can be performed.
3.7.2
Restore Manufacturer Parameters to Default
Upon receiving a “Restore Manufacturer Parameters to Default” request from the network, the
module will issue a reset command to the Application Object (FFh) with CmdExt[1] set to 01h
(Factory default reset).
A factory default reset can only be performed in the EtherCAT state PREOPERATIONAL. Per-
forming a reset in another state than PREOPERATIONAL will generate SDO abort code
08000020h (invalid state).

Configured Station Alias (Node Address)
The Configured Station Alias (node address) range is 1... 65535. Address 0 indicates that the
device has yet to be configured. The Configured Station Alias is stored in the slave EEPROM
and may be used by some masters as a node address.
For most applications it is recommended to leave the Configured Station Alias unchanged, but
it is possible to assign each slave an address from the network.
3.9
Device ID
The Device ID is used by the master to explicitly identify a slave. This is e.g. useful when chang-
ing a faulty device during runtime, a so called HotConnect application. A preconfigured device
can be entered into the network, and its Device ID can be set to the same Device ID as the
faulty device was appointed.
It is also useful to prevent cable swapping when there are two or more identical devices on the
network.
The Device ID range is 1... 65535. Address 0 indicates that the device has yet to be configured.
The value can be set using the Network Configuration Object, instance 1.
In the Anybus CompactCom M30 EtherCAT, the Network Configuration Object, instance 3 was
used for the Device ID
