Diagnostics
7.2.1
Error Messages
When error messages are generated, the "IN_OP" signal (in operation) is reset and
the SF LED (group error) is lit.
If the VS 130 is attached to PROFIBUS DP, all error messages with a number in
the "Bit No. Starting at Diagnostic Byte 0 (DP)" column in the following table trigger
a diagnostic interrupt on the DP master. How to read out the diagnostic information
made available on the VS 130 and how to evaluate it is explained in Section 7.4.

Description
An error occurred during
transfer of data over
PROFIBUS or the
processing unit is not (yet)
in the data exchange phase.
Note: After downloading the
system data from
HW Config to a DP master
again, the master is not
capable of data exchange
for a brief time.
The system parameters
were not found or could not
be restored.
The connected sensor head
is not supported by the
firmware of this processing
unit.
The sensor head is
defective or not connected
An error has occurred
transferring the image from
the sensor head to the
processing unit causing loss
of a single image
The disable signal changes
during training
Possible Remedies
Check the connection from the
processing unit to the DP master.
Make sure that the set PROFIBUS
address is correct.
If you do not want to operate the
device over PROFIBUS, deactivate DP
in the Result>Trigger>Control menu.
If this does not help, the hardware may
be defective.
Set the system parameters again.
Check that the sensor head connected
actually belongs to the processing unit
based on the order numbers.
Check whether the firmware version of
the processing unit supports the
connected sensor head and, if
necessary, update the firmware.
Check the connection to the sensor
head. The connector is possibly not
correctly inserted. It is also possible
that the cable to the sensor head is
damaged or the sensor head or the
processing unit is defective.
Check the cable between the sensor
head and the processing unit for
damage.
In a noise polluted environment: Shield
cables and remove any possible
sources of interference.
You must not change over from
operation using the buttons on the
processing unit to operation by the
digital inputs/outputs or vice versa
during training. End the training run
