Troubleshooting
Section 7-2
100
Configuration problems (continued)
Description Possible cause Possible remedy
Not able to store /
restore parameters. Incorrect signature. To store parameters, the signature ‘save’ has
to be written to sub-index 01h of index 1010h.
To restore parameters, the signature ‘load’
has to be written to sub-index 01h of index
1011h.
See section 3-3-2-9 for details.
Non-volatile memory error.
When the Unit detects a non-volatile memory
error, an emergency message is transmitted
(see section 6-2) and error code 05h will be
blinking on the 7-segment display.
Try to store the configuration again and / or
restart the Unit. Note that storing the
configuration takes approx. four seconds; the
Unit should not be reset in this period.
If the error keeps occurring, replace the Unit.
I/O data communication problems
Description Possible cause Possible remedy
7-segment display
value is Blinking. The 7-segment display indicates the cause.
Refer to section 6-5 for a list with error codes. Try to solve the cause and/or restart the Unit.
If this does not help, replace the Unit.
7-segment display
dots are ON. The Unit is in ‘Pre-Operational’ state.
Also indicated by IR n+3.00 and IR n+3.01.
Send the NMT command
‘Start_Remote_Node’ to the Unit or set IR
n.01. The Unit should go to Operational state
and the dots should go OFF.
7-segment display
dots are Blinking. The Unit is in ‘Stopped’ state.
Also indicated by IR n+3.00 and IR n+3.01.
Send the NMT command
‘Start_Remote_Node’ to the Unit or set IR
n.01. The Unit should go to Operational state
and the dots should go OFF.
The network cabling is not correct. Check if the correct pins of the bus connector
are connected (see section 3-1-5), if there are
no short circuits, if the stub-lines are not too
long, and if the network is terminated at the
appropriate places (see section 3-3-1).
The Unit operates on a different baud rate than
the other units on the network. Configure all the units on the network to the
same baud rate.
No I/O data is
exchanged with the
PLC although the
RUN LED is ON.
7-segment display
value is not Blinking
and the dots are
OFF.
The CANopen communication is disabled.
IR n.00 is not set. Display value is FFh. Set IR n.00 ON.
Application object(s) not mapped to a PDO. Configure the desired application object(s) to
a PDO and configure the communication
parameters of that PDO (see section 3-3-2-1
and section 3-3-2-2).
PDO is not enabled. The highest bit of the COB-ID (sub-index 01h
of the PDO Communication Parameters)
determines whether the PDO is valid or not.
Normally, the configuration tool enables the
PDO (by clearing this bit) when the application
object mapped to the respective PDO is
linked to another Unit. Check if this bit is
cleared and if not, clear it manually.
Wrong transmission type Set the correct transmission type. See section
3-3-2-1 for the possible transmission modes.
Application object(s) not mapped to a PLC
address. If an application object is not mapped
to a PLC address, it might appear that the Unit
is not communicating. Configure the Unit settings to map the desired
application object(s) to a PLC address.
