CJ-series PROFINET IO Controller Unit Operation Manual for NJ-series CPU Unit (W511)
Name of device variable
for CJ-series Unit
Type
R/W
Area
Function
*_UnitErr
BOOL
RO
Unit error flag
FALSE: Controlled by the Unit if all of the follow-
ing variables are all FALSE:
•
*_CtlrErr
•
*_NewErr
•
*_ParamStorErr
•
*_ParamLoadErr
•
*_FileRdErr
•
*_ErrLogStorErr
TRUE: The Unit error flag combines the status of
all error flags in *_UnitSta. The bit flag is turned
ON by the Unit if any of the following variables
are on:
•
*_CtlrErr
•
*_NewErr
•
*_ParamStorErr
•
*_ParamLoadErr
•
*_FileRdErr
•
*_ErrLogStorErr
*_CtlrErr
BOOL
RO
Controller
error flag
FALSE: Turned OFF by the Unit if all of the fol-
lowing variables are FALSE (see
4-2-3 IO Con-
troller Status 1
):
•
*_LinkSta
•
*_HwErr
•
*_CfgEff
TRUE: Turned ON by the Unit if any of the fol-
lowing variables are TRUE:
•
*_LinkSta
•
*_HwErr
•
*_CfgEff
*_NewErr
BOOL
RO
Error log con-
tains new
errors
FALSE: Turned OFF by the Unit on restart or if
the error log is cleared or read.
TRUE: Turned ON by the Unit if a new error is
added to the error log.
*_ParamTxActSta
BOOL
RO
Parameter
transfer in
progress
FALSE: Turned OFF by the Unit if no configura-
tion data transfer is in progress
TRUE: Turned ON by the Unit and indicates the
following:
•
Retrieval of internally stored configuration ad
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.
*_ParamStorErr
BOOL
RO
Local parame-
ter storage
error
FALSE: Turned OFF by the Unit if the Configura-
tion and setup data has been transferred to the
non-volatile memory successfully.
TRUE: Turned ON by the Unit if an error
occurred during the storage of the data trans-
ferred from the configuration software to the
CJ1W-PNT21 non-volatile memory.
If the error occurred, the data in the non-volatile
memory may be corrupted and a new Configura-
tion must be downloaded to the Unit.
