■Buffer memory area assignment
This section describes 'Command interface (CIF)' (Un\G1000 to Un\G1066) assignment for sending an EMCY message
manually.
The following table shows the transmit message assignment.

• The NMT state of the own node must be Operational or Pre-operational to send an EMCY message.
• When an EMCY message is sent manually, the bit set in the error register of the EMCY message is turned
on in Error register (index 1001H). Note that the bit cannot be turned off automatically.
• When an EMCY message is sent manually, the emergency error code set in the EMCY message is stored
in Pre-defined error field (index 1003H). As with when the EMCY message is sent automatically, a
maximum of 15 latest emergency error codes are stored in Pre-defined error field (index 1003H).
