On smaller PROFINET IO Networks the sequence from starting the
PROFINET IO core software to being in full Data Exchange with all the IO
Devices can be very fast that the individual steps can not be distinguished.
Unit errors are errors which occur at starting or normal operation of the system
and which prevent the Unit from functioning correctly in the PLC system.
Usually these errors also cause the CS/CJ PLC CPU ERR/ALM indicator to be
lit or flashing. For more information on error indications in the PLC, refer to the
CS1 Series CPU Unit Operation Manual (W339) or the CJ Series CPU Unit
Operation Manual (W393) for more details.
