Troubleshooting
Source of fault
Possible cause
Remedy
The PWR/ERR LED does
not illuminate.
Power supply not
guaranteed.
Ensure the power supply using a
24 V DC source.
The device is still booting
up.
Wait until the booting process is
complete.
The PWR/ERR LED
flashes green.
(For Ethernet/IP
communication only)
Memory overflow.
Reduce the data hold time (see
chapter 7.4.11).
The PWR/ERR LED
illuminates red.
(For PROFINET
communication only)
No physical connection to
the master, e.g. due to lead
breakage.
Check the lead and repair if
necessary.
The assigned device name
is incorrect
Configure the same device names in
the master and in the device.
The Link/Act LED does not
illuminate.
No physical network
connection, e.g. due to
lead breakage.
Check the lead and repair if
necessary.
The icon in the display (e.g.
CH1) does not appear
even though the read/write
head is connected to port
1.
The lead is faulty or not
connected correctly.
Check the lead and repair if
necessary.
The read/write head is
faulty.
Check the read/write head and
repair if necessary.
The LEDs in the reader
and the CHx icon on the
IDENTControl display are
flashing.
The reader connected
does not support the tag
type set.
Select a tag type that is supported by
the reader.
A read command (e.g.
SR ...
) gives the status 4
even though the syntax is
correct.
An incorrect tag type (e.g.
IPC02) is set for the
relevant channel. The read
commands only function
with read/write tags and
not with read only tags.
Set the correct tag type (e.g. IPC03)
or "Autodetect" using the
CT...
command or via the display
(IDENTControl.../ Config Channels).
The
SG
or
EG
(get
configuration) command
gives the status 4 even
though the syntax is
correct.
IPC03 is not set for the
relevant channel. The
configuration commands
only function if the
read/write tag IPC03 is set
and not in Autodetect
mode.
Set the tag type IPC03 using the
CT...
command or via the display
(IDENTControl.../ Config Channels).
The IP address of the
device is 000.000.000.000
With DHCP server:
No network parameters.
Configure the DHCP server.
The website cannot be
displayed.
The IP address is incorrect.
With the DHCP server
: Make sure
that the IP address entered in the
browser corresponds with the
address assigned to the device.
Without DHCP server
: Check the
IP address entered in the browser to
see whether it corresponds with the
fixed IP address set in the device.
Check the subnet mask in both
cases.
