IR n+3.09 Network power failure
The network transmission interface of the C200HW-CORT21-V1
is galvanically isolated and requires 24 V DC power supply via
pin 1 and 5 of the bus connector.
0: No network power failure.
1: Network power failure.
This error is also indicated on the 7-segment display (see
section 6-5).
IR n+3.10 Bus Off
If the C200HW-CORT21-V1 detects an abnormal rate of errors
on the bus, the Unit will go 'Bus Off'. This means that all
CAN(open) communication is stopped. The Unit will attempt to
go online again after toggling IR n.03 ‘Start Bus Off recovery’.
0: Unit is online.
1: Unit has gone Bus Off.
This error is also indicated on the 7-segment display (see
section 6-5).
If a network power failure is detected during Bus Off, IR n+3.10
is reset and IR n+3.9 is set. When the network power failure is
solved, the Bus Off recovery sequence is started automatically.
After a successful Bus Off recovery, the C200HW-CORT21-V1
will enter pre-operational state.
IR n+3.11 Heartbeat / Life guarding error
The C200HW-CORT21-V1 can monitor the heartbeat of another
node
or perform life guarding on the NMT master that guards the
C200HW-CORT21-V1.
In case the Heartbeat mechanism is enabled and the heartbeat
producer fails to send the heartbeat within the set heartbeat time
(see section 3-3-2-3), IR n+3.11 is set.
In case Life Guarding is enabled and the NMT master fails to
request the status within the Node Life Time (see section 3-3-2-
4), IR n+3.11 is set.
IR n+3.11 is reset when heartbeat or remote transmission
requests from the NMT master have resumed.
0: No Heartbeat / Life guarding error
or the Heartbeat consumer / Life guarding is not enabled.
1: Heartbeat / Life guarding error.
This error is also indicated on the 7-segment display (see
section 6-5).
IR n+3.12 DM setting error
If an error is made in the Unit's DM settings (see section 4-2-3),
IR n+3.12 is set.
0: No DM setting error. IR n+4 = 0000
1: DM setting error. See IR n+4 for details.
The ERR-LED will be blinking to indicate a non-fatal error,
and the CANopen communication is disabled.
