Unit operation
Bit 00 is turned OFF by the Unit if Bit 01, Bit 03, Bit
06, Bit 07, Bit 09 and Bit 13 in CIO Word n+4 are
OFF
The Unit error flag combines the status of all error
flags in CIO Word n+4. The bit flag is turned ON by
the Unit if Bit 01, Bit 03, Bit 06, Bit 07, Bit 09 or Bit 13
in CIO Word n+4 is ON.
Bit 01 is turned OFF if none of the flags in Master
status word 2, i.e. CIO Word n+6 is ON.
The Master error flag combines the error flags in the
Master status 2 Word, i.e. CIO Word n+5. Master
status word 2 contains all error flags related to the
PROFINET IO Controller functions.
Bit 01 is turned ON if any of the flags in IO Controller
status word 2, i.e. CIO Word n+6 is ON
This bit is always set to OFF by the Unit.
The bit flag is set to OFF at unit restart or by the Unit
if the error log is
• cleared using the ERROR LOG CLEAR FINS
command, or
• read, using the ERROR LOG READ FINS
command
The bit flag is set to On by the Unit if a new error is
added to the error log.
When OFF, this bit indicates that no Configuration
data transfer is in progress.
The Parameter transfer in progress indicates:
• Retrieval of internally stored configuration and
set-up data.
• Storing of configuration and set-up data sent by
the configuration software in progress.
During this transfer no other transfer of data can be
started in parallel.
This bit will be set to OFF by the Unit.
When OFF, this bit indicates that the Configuration
and setup data has been transferred to the non-
volatile memory successfully.
The local parameter storage error flag will be ON if
an error occurred during the storage of the data
transferred from the configuration software to the
CJ1W-PNT21.nal non-volatile memory.
If the error occurred, the data in the non-volatile
memory may be corrupted and a new Configuration
must be downloaded to the Unit.
