IO Controller Unit response
The Unit is started and is capable to receive a PROFINET Configuration. It will
not initiate PROFINET IO Communication. Records the error in the errorlog.
CIO Area Flags allocated to the IO Controller Unit
IO Controller status 1 (word n+5) bit 07 will be OFF
Correction
Use Cx-ConfiguratorFDT to download a valid PROFINET IO Configuration in
the IO Controller. Or restore the Configuration from a Compact Flash memory
card. Replace the IO-Controller if the error recurs.
/i
Likely cause
The PROFINET IO controller could not esthablish a Ethernet link to the
connected switch or IO Device.
IO Controller Unit response
The Unit is not capable to communicate on the PROFINET network and
therefore control to the IO Devices will be lost. The Unit will stop processing.
Records the error in the errorlog.
CIO Area Flags allocated to the IO Controller Unit
IO Controller status 2 (word n+6) bit 03 will be ON
Correction
Check the Ethernet cable and switch or IO DeviceRestart the IO Controller.
Bus hardware error
/i
Likely cause
Disturbance on the Ethernet network causes the Ethernet interface to fail.
IO Controller Unit response
The Unit is not capable to communicate on the PROFINET network and
therefore control to the IO Devices will be lost. he Unit will stop processing.
Records the error in the errorlog.
CIO Area Flags allocated to the IO Controller Unit
IO Controller status 2 (word n+6) bit 03 will be ON
Correction
Check the Etehernet network for prossible causes of disturbance. This can be
EMC influences, broken or shorted Ethernet cable, faulty connectors,
defective Ethernet switches or IO Devices and grounding problems to name a
few. This will result in interrupted data streams or broken messages.
