Start-up problems
Description Possible cause Possible remedy
No LEDs are ON or
Blinking. The PLC’s power is off. Turn the PLC’s power supply on.
The Unit is defective. Replace the C200HW-CORT21-V1.
The RUN LED is
Blinking. The same Unit number has been set on
another Special I/O Unit, causing an I/O UNIT
OVER error in the PLC. Make sure that the same Unit number is not
used by more than one Special I/O Unit and
restart the PLC.
I/O table verification error. A Unit has been
removed or the Unit number setting has been
changed causing an I/O SET ERR error in the
PLC. Verify the I/O table and/or register the I/O
table again.
Another Special I/O Unit or Interrupt Input Unit
has not been initialised, causing a CPU
WAIT’G error in the PLC. Check and/or remove the defective Unit.
The Unit is defective. Replace the C200HW-CORT21-V1.
ERR LED is
Blinking. A non-fatal error due to incorrect Unit settings.
The cause is reported in IR n+4. Try to solve the cause and restart the Unit. If
this does not help, replace the Unit.
ERR LED is ON. A fatal error was detected at start-up.
The cause is reported in IR n+3.13, IR n+3.14 Try to solve the cause and restart the Unit. If
this does not help, replace the Unit.
Configuration problems
Description Possible cause Possible remedy
Not able to access
(read / write) an
object entry. The object entry does not exist or has the
wrong attribute. Check the EDS-file (Appendix A) if the object
entry exists. If the object exists, check the
attribute of the object.
To read an object, the attribute has to be RO,
RW, RWW, or RWR.
To write to an object, the attribute has to be
WO, RW, RWW, or RWR.
The CANopen state of the Unit is ‘Stopped’ or
‘not active’.
IR n+3.01, IR n+3.00 = 00 (not active) or
IR n+3.01, IR n+3.00 = 11 (Stopped)
If ‘not active’, wait until the Unit is initialised,
set IR n.00, and/or start the Bus Off recovery
sequence by toggling IR n.03.
If ‘Stopped’, send the NMT command
‘Enter_Pre-operational_State’ or
‘Start_Remote_Node’.
The SDO access has the wrong syntax. Check the CANopen communication profile
specification for the correct syntax of an SDO
access.
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 at a different baud rate than
the configuration tool. Configure both to communicate on the same
baud rate.
The Unit is defective. Replace the C200HW-CORT21-V1.
