Value Description
80D3h The SDB cannot be accessed since it does not exist.
80D4h Bad SDB structure: the SDB internal pointer points to an element outside of the SDB.
80D5h The record is static.
14.1.44 SFC 56 - WR_DPARM - Write default parameter
The SFC 56 WR_DPARM (write default parameter) transfers the record RECNUM from
the respective SDB to the target module, irrespective of whether the specific record is
static or dynamic.
These SFC can be used for digital-, analog modules, FMs, CPs and via PROFIBUS DP-
V1.
Parameters
Parameter Declaration Data type Memory block Description
REQ INPUT BOOL I, Q, M, D, L,
constant
REQ = 1: write request
IOID INPUT BYTE I, Q, M, D, L,
constant
Identifier for the address space:
54h = peripheral input (PI)
55h = peripheral output (PQ)
For hybrid modules the SFC returns the area
identifier of the lower address. When the
addresses are equal the SFC returns identifier
54h.
LADDR INPUT WORD I, Q, M, D, L,
constant
Logical base address of the module. For hybrid
modules the lower of the two addresses must be
specified.
RECNUM INPUT BYTE I, Q, M, D, L,
constant
Record number
(valid values: 0 ... 240)
RET_VAL OUTPUT INT I, Q, M, D, L The return value contains an error code if an
error is detected when the function is being pro-
cessed.
BUSY OUTPUT BOOL I, Q, M, D, L BUSY = 1: the write operation has not been com-
pleted.
Two distinct cases exist for RET_VAL = 8xxxh:
