4.4 Errors from the optical reader
Ident profile and Ident blocks, standard function for Ident systems
130 Function Manual, 10/2018, C79000-G8976-C387-04
Errors from the optical reader
In the event of error messages, the "IN_OP" signal (in operation) is reset and the
"STATE/SF" 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.
Table 4- 3 Error messages via the "STATUS" output parameter ("IN_OP" is reset)
0xE1FE0200 The connection from the internal interface to the image sensor is disrupted.
If the error continues to occur after turning on the device again, contact technical support.
0xE1FE0400 Transmission error
The send buffer is full because the data cannot be queried in an adequately short time.
Reduce the trigger frequency or process the results faster.
If necessary, change the update time in the PROFINET configuration.
If necessary, the transmission speed of the CM connection can also be increased. To cover short peaks,
the image buffer size of the program can be increased on the "Image acquisition", "Control" tab.
0xE1FE0600 Program cannot be started because there is not enough memory or the program is damaged.
Reduce the memory requirements and repeat "Save program".
0xE1FE0700 Comparison error
The program could not be created due to bad match settings.
Adapt the match settings or use a suitable test object.
0xE4FE0400 Internal file error
An error occurred while saving to read-only memory.
Please contact technical support if this error occurs frequently.
0xE4FE0600 Lamp overload
The connected lamp was overloaded. The configured or default "Maximum duty cycle" in "Options", "Light-
ing" tab, was exceeded.
Decrease the trigger frequency, reduce the exposure time or use a more powerful lamp.
