NDR OUTPUT BOOL 0: -
1: Data accepted
This parameter indicates whether or not the
job was completed without errors.
ERROR OUTPUT BOOL 0: -
1: Error
Error code
STATUS OUTPUT WORD - Status code
See Table 7-12 Page A-247
CHECK_
IOPS
OUTPUT BOOL 0: All IOPS set to
GOOD
1: At least one
IOPS set to BAD
Auxiliary bit that indicates whether or not it is
necessary to evaluate the IOPS status area.
IOPS OUTPUT ANY (as
VARTYPE
only
BYTE is
permitted)
The address of
the data area
points to one of
the alternatives:
 Memory bit
area
 Data block
area
Length:
For the maximum
value, refer to the
device-specific
Part B of this
manual in the
“Performance
Data” chapter.
This may differ for
controller or
device mode.
A status bit is transferred per byte of user
data.
The length information depends on the length
in the RECV parameter (one bit per byte)
= (Length LEN + 7/ 8)
Controller mode:
Address gaps are also transferred according
to the RECV parameter.
Address gaps are transferred with the status
GOOD.
Device mode:
Address gaps are not transferred.
The block begins the transfer of the status for
address 0.
Note:
 The minimum length of the ANY pointer is
(length LEN + 7/ 8)
ADD_INFO OUTPUT WORD Additional
Diagnostic
Information
In controller mode:
 0: No alarm
 >0: Number of
pending
alarms
In device mode,
the parameter is
always = 0.
Parameter Expansion
Note:
The ADD_INFO parameter is also updated
when there are no INPUT addresses
configured on the PROFINET IO controller. In
this case, the PNIO_RECV block is called with
a length LEN > 0 (for example LEN = 1 byte).
It then transfers an address gap of 1 byte.
The parameter expansion can be used as of
firmware V2.0 of the CP 343-1. In older
firmware versions, the parameter is reserved.
Note
Remember that all output parameters may only be evaluated when the block
signals either NDR = 1 or ERROR = 1.
