System Stop
The status "System stop" is indicated with the two light-emitting diodes
"
UL
" and "
DIA
". During a system stop the outputs are set to the safe
status ('0') and the bus traffic to the DP master is interrupted. The system
stop can only be quit by a restart of the assembly ('Network on').

Display of status "System stop"
The VAM has recognized a module, that is not supported by the firmware
version of the bus connection.
•
To operate the I/O module the firmware must be updated.
•
If an error occurs with the current firmware version, the module has a
hardware error.
The following I/O configurations lead to a system stop because of a
misconfiguration:
•
No I/O modules equipped.
•
More than 16 I/O modules equipped.
•
More than 64 bytes inputs equipped.
•
More than 64 bytes outputs equipped.
•
The total of the parameterization data of all modules is greater than
64 bytes.
•
The total of the parameterization data of all modules is greater than
64 bytes.
When booting (‘Network on’) the bus connection, the hardware
components are tested. Furthermore, during the cyclic operation the I/O
configuration and the transmission quality to the I/O modules are
monitored. If an error occurs, the assembly is set to system stop
‘Exceptional error HW’.
