10.1 Error and diagnostics messages
SIMATIC MV500
176 Operating Instructions, 06/2018, C79000-G8976-C494-01
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.

W#16#5007 07 E1FE04 The send buffer is full
because 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 under
