10.1 Error and diagnostics messages
SIMATIC MV500
176 Operating Instructions, 05/2019, C79000-G8976-C494-02
10.1.2 Error messages
With error messages, the "IN_OP" signal (in operation) is reset and the "ER" LED is lit red
permanently.
In addition, the "Ready" or "Done" bit is reset with a connection via the Ident profile.
If the optical reader is connected to PROFINET IO, these error messages trigger a
diagnostics interrupt on the relevant I/O controller. Refer to I/O diagnostics for a description
of how to read out and evaluate the diagnostic information made available on the optical
reader.

Description
Corrective measures
Fault in inter-
nal interface
to the image
sensor
W#16#5000
01 E1FE02 There is a fault in the con-
nection of the internal inter-
face to the image sensor.
If the error continues to occur
after the device has been turned
on again, contact technical sup-
port.
W#16#5001
Error during
DISA signal
change
W#16#5003 03 E6FE04 When the program is saved,
the DISA signal is changed
at an invalid location.
Check the sequence of applied
signals. Start the program saving
process again.
Error in se-
quence
W#16#5004 04 E6FE04 While the program is being
saved, the time sequence of
applied signals is not ad-
hered to.
Check the sequence of applied
signals. Start the program saving
process again.
Program
cannot be
started
W#16#5005 05 E1FE06 Not enough memory or
program damaged.
Reduce the memory require-
ments and repeat "Save pro-
gram".
Internal file
error
W#16#5005 05 E4FE04 An error occurred while
saving to read-only memory.
Please contact technical support
if this error occurs frequently.
Transfer error
TCP or
RS232
W#16#5007 07 E1FE04 The send buffer is full be-
cause the data cannot be
sent in an adequately short
time.
Reduce the trigger frequency.
With TCP: Process the results
on the server side faster.
A high load on the network to
which the optical reader is con-
nected can also block the trans-
fer of the data. If necessary,
check the network connection.
With RS-232: Increase the
transmission speed. In addition,
the size of the image buffer in
the WBM can be increased un-
der "Program > Image acquisi-
tion > Mode".
