/i
MS indicator
ON (green)
Likely cause
During startup of the IO Controller encountered a problem interpreting the
PROFINET IO Configuration file. This could be because the Unit started for
the first time and does not contain a configuration file yet. Also the
Configuration file could be damaged.
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 error log.
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
MS indicator
ON (red)
Likely cause
The PROFINET IO controller could not establish 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 error log.
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 Device Restart the IO Controller.
Bus hardware error
/i
MS indicator
