Display: Temporary error
"Temporary errors: xx" on the SIMATIC VS120 Vision Sensor indicates that there was a
problem on the connection over PROFIBUS DP or PROFINET IO, where "xx" is the number
of problems.
Example:
During operation, new project engineering data is transferred to the CPU with HW Config.
The CPU then terminates the connection to the slaves and restarts communication with
PROFIBUS DP. This is noted on the SIMATIC VS120 Vision Sensor and the error messages
are incremented as temporary errors.
If the counter reading for temporary errors increases, this may indicate that the connection
with PROFIBUS DP was restarted often or that the slaves had new parameters assigned by
the CPU. This symptom indicates that the PROFIBUS DP segments are not working
efficiently. It may be necessary for a PROFIBUS DP systems specialist to check the entire
system.
