260
Symbol
Meaning
red
No memory module is plugged in the safety relay.
red
Memory module is defective.
green
Programming of the memory module was successful.
red
Programming of the memory module was not successful.
red
More configuration data were transferred to the safety relay than can be
stored in the memory module.
green
The memory module was delected by command beforehand.
Symbol
Meaning
CPU STOP: The user program in the PLC is not processed any more.
yellow
•
Master STOP: A disturbed communication with the fieldbus master was
•
detected.
red
Communication via PROFIBUS DP has been interrupted.
red
During parameter assignment in existing communication connection a
parameter assignment error occurred.
red
The actual configuration of an existing communication connection does not
match the target configuration. This resulted in an error.
yellow
The DP master is no longer receiving any process data.
Possible cause: The controller was stopped with the user program (=CPU
STOP).
green
The communication connection to the fieldbus master is set up.
Configuration and parameter assignment of the safety relay have been
executed successfully.
Symbol
Meaning
red
Communication via the device bus interface is interrupted.
red
An error occurred during parameter assignment in existing communication
connection.
red
The actual configuration of an existing communication connection does not
match the target configuration. This resulted in an error.
yellow
No more process data is exchanged.
green
The internal communication link is set up.
