(B#16#....)
Explanation (DVP1)
Description
B1 Write length error The length information in the RECORD parameter is
incorrect.
• With "RALRM": Length error in AINFO
Note
: Refer to the online information system of
STEP 7 for immediate access to information on how
to interpret the "AINFO" returned buffers.
• With "RDREC (Page 385)" and "WRREC
(Page 385)": Length error in "MLEN"
B2 Invalid slot The configured slot is not occupied.
B3 Type conflict Actual module type does not match specified module
type.
B4
Invalid area
DP slave or module reports access to an invalid area.
B5
Status conflict
DP slave or module not ready
B6
Access denied
DP slave or module denies access.
B7 Invalid range DP slave or module reports an invalid range for a param-
eter or value.
B8
Invalid parameter

• With "WRREC (Page 385)": Buffer too small (subsets
cannot be written)
BA to BF User specific DP slave or module reports a manufacturer-specific error
when accessing. Please check the documentation from
the manufacturer of the DP slave or module.
C0 Read constraint conflict
• With "WRREC (Page 385)": The data can only be
written when the CPU is in STOP mode.
Note
: This means that data cannot be written by the
user program. You can only write the data online with
a PG/PC.
• With "RDREC (Page 385)": The module routes the
data record, but either no data is present or the data
can only be read when the CPU is in STOP mode.
Note
: If data can only be read when the CPU is in
STOP mode, no evaluation by the user program is
possible. In this case, you can only read the data
online with a PG/PC.
C1 Write constraint conflict The data of the previous write request to the module for
the same data record has not yet been processed by the
module.
C2 Resource busy The module is currently processing the maximum possi-
ble number of jobs for a CPU.
C3
Resource unavailable
The required operating resources are currently occupied.
