Description
Error signaled during
training via the PLC or
digital I/O
The stored code could not
be read from the EPROM or
has not been trained.
In the evaluation mode:
The trigger sequence is
faster than the permitted
evaluation time set for
Cycletime.
In the evaluation mode:
An error occurred
transferring the decoded
string.
Invalid parameter
assignment over
PROFIBUS
In the evaluation mode:
The evaluation time of the
last code that was read is
higher than the time set in
the
Settings>Read>Cycletime
menu.
Diagnostics
Possible Remedies
A timing error occurred when training
via the digital inputs/outputs. Make
sure that you keep to the correct
timing.
Retrain the code.
The Cycletime setting must be adapted
to the actual trigger frequency. In some
cases, it may be necessary to reduce
the parts rate.
Make sure that the trigger is not
bouncing.
When outputting over RS-232:
Increase the set bit rate of the RS-232
interface. It may be necessary to
reduce the parts rate.
When outputting over PROFIBUS:
•
Check the connection to the
PROFIBUS master.
•
Increase the transmission rate of
the DP master. It may be
necessary to reduce the parts rate.
•
Check your handshake
programming.
•
Check that the cycle time on the
DP master is not too high.
•
Increase the handshake
monitoring time
(Settings>Ports>DP>Timeout
menu of the processing unit)
Default parameter settings (all zero)
Increase the time in the
Settings>Read>Cycletime menu in
keeping with the maximum time
allowed for reading in your application.
This must be higher than the minimum
time required for reading a code.
