Description:
The
‘life guard’
is one of the two parameters used by the node guarding protocol (errors detection).
When
‘Heartbeat time’
is inactive and
‘life guard’
is different from 0,
eNod4
responds to NMT master periodic (period
equal to life guard) remote transmit requests.
5.9.5
0x100D / 0x00 : life time factor
•
access : R/W
•
data type : unsigned8
•
default value : 0
•
mappable ? : N
•
admitted values : from 0 up to 255
Description:
By multiplying the
‘life guard’
by the
‘life time factor’
, the node life time (cf. §4) can be determined.
When node guarding is active, if the node has not be polled within this duration (in ms),
eNod4
state is set to stopped.
eNod4
behavior while stopped can be configured via the object at index 0x4800.

In CANoppen® communication protocol, storing all settings into
eNod4
EEPROM memory requires writing through
SDO the ASCII string « save » (65766173
H
) to sub-index 0x01 of entry 0x1010 of the object dictionary (called
‘save all
parameters’
in the EDS file).

When accessing to sub-index 1 with a SDO read request,
eNod4
cell responds with a value of 1 that means that
parameters are stored in non-volatile memory only on request.
Note:
Restore to default settings functional command is not available in CANopen® communication protocol.
5.9.7
0x1014 / 0x00 : Emergency COB-ID
•
access : RO
•
data type : unsigned32
•
default value : 0x81
•
mappable ? : N
•
admitted values : from 0x81 up to 0xFF
Description:
The COB-ID of emergency messages transmitted by
eNod4
is stored at this index. Its value automatically
is updated if the node identifier is modified.

Description: eNod4
is able to monitor the Heartbeat generated by another node (see §4) of the network (in general
the master). Two settings must be defined through the object at sub-index 0x01:
the heartbeat time period
, coded on the 16 LSB bits
the node ID
of the heartbeat producer to monitor, coded on the 16 MSB bits (from 0x01 up to
0x7F)
