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.

Application object(s) not mapped to a PDO.
PDO is not enabled.
Wrong transmission type
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.

Possible cause
Possible cause
Possible remedy
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.
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.
Possible remedy
Try to solve the cause and/or restart the Unit.
If this does not help, replace the Unit.
Send the NMT
'Start_Remote_Node' to the Unit or set IR
n.01. The Unit should go to Operational state
and the dots should go OFF.
Send the NMT
'Start_Remote_Node' to the Unit or set IR
n.01. The Unit should go to Operational state
and the dots should go OFF.
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).
Configure all the units on the network to the
same baud rate.
Set IR n.00 ON.
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).
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.
Set the correct transmission type. See section
3-3-2-1 for the possible transmission modes.
Configure the Unit settings to map the desired
application object(s) to a PLC address.
