8 Monitoring
8.1 Interruption of the DeviceNet communication
An interruption of the DeviceNet communication, e.g. by a cable break or a failure of the host (PLC,
scanner), is detected by the communication module.
Responses to communication faults can be set in the DeviceNet object
Lenze Class (0x65 / 101)
( 74) or under the Monitoring tab:
Settings Description
Idle Mode The scanner does not transmit any I/O data if it is in idle state.
If the device (communication module) is in the idle state, the response
parameterised here ( C13880/1 / C14880/1 ) is activated in the drive.
I/O connection timeout The data transmission of the poll or CoS/Cyclic I/O connections can be
monitored by timeouts.
The timeout values are configured within the Connection Class (0x05 / 5)
( 70) - instance 2 (poll I/O) or instance 4 (CoS/Cyclic I/O), attribute 9.
After the monitoring time has elapsed, the response parameterised here
( C13880/2 / C14880/2 ) is activated in the drive.
Communication error The device (communication module) automatically recognises
communication faults.
If a communication fault is active, the response parameterised here
( C13880/3 / C14880/3 ) is activated in the drive.
