6.9 Warning objects

In order to know the meaning of warning message make reference to the
document “CiA Draft Standard 301” on chapter “SDO abort codes” available on
www.can;cia.org.

6.10 Emergency objects

Emergency (EMCY) objects are transmitted by the device when an internal error
occurs.

EMCY structure:

IDENTIFIER

CAN Data Byte

COB;ID(hex)

0

1

2

3…7

see object 1014h

Error code

Sub of error

register

Specific code

LSB

MSB

01

00…00

Defined error codes:
1000h = Node guarding error
5530h = Flash memory error

6.11 Node guarding protocol

On  start  up  the  “Node  guarding  protocol”  is  disabled,  the  Master  device  can
enable the protocol by sending an RTR (remote transmit request).

Guard time:   time between 2 RTR.
Node life time:  max device response time.

“Node life time” = “Obj_100C”

∗

“Obj_100D”

“Node guarding” is enabled if “Node life time”

≠

0.

If  the  Slave  is  not  guarded  within  the  "Node  life  time",  it  warns  with  a  “Life
Guarding Event”.
The  red  LED  indicates  the  Node  guarding  error,  objects  1001h  and  1003h  are
updated and error message is sent.
To remove the error send a “Reset node” command.
