Parameterizing data
The parameterizing data set of an SPL connection involves the following values:
● Identifier:
DP_DP_ID: MD13331 $MN_SAFE_SDP_ID
Name: MD13332 $MN_SAFE_SDP_NAME
● Connection number: MD13333 $MN_SAFE_SDP_CONNECTION_NR #
● Communication parameters:
I/O start address: MD13334 $MN_SAFE_SDP_LADDR #
Monitoring time: MD13335 $MN_SAFE_SDP_TIMEOUT #
● Net data parameters:
SPL assignment: MD13336 $MN_SAFE_SDP_ASSIGN
F-net data filter: MD13337 $MN_SAFE_SDP_FILTER
● Error response: MD13338 $MN_SAFE_SDP_ERR_REAC #
For SPL connections with the same ID, all of the parameters designated with # must be
identical. In case of an error, Alarm 27305 "F_DP: Parameter MD %1[%2] < > MD %3[%4]".
Input/output data
The input and output data provide the user or SPL programmer an interface compatible to the
SIMATIC F-application blocks using system variables.
Error responses
The system responses when a communication error occurs can be influenced by the user by
correspondingly setting the machine data $MN_SAFE_SDP_ERR_REAC or, at a later point in
time by programming the system variables $A_FSDP_ERR_REAC in the SPL program.
SPL couplings (sub-slots)
Just the same as for PROFIsafe, also for F_SENDDP, only contiguous areas of SPL output
data ($A_OUTSE[x] to $A_OUTSE[x+y]) can be assigned to an SPL connection. Several SPL
connections must be parameterized if several non-contiguous pieces of SPL output data are
to be transferred. These are characterized due to the fact that the parameters of the SPL
couplings differ, but all other parameters of the SPL connection are identical. As part of the
F_DP communication, these SPL connections are combined to form a single SPL connection
communicating via PROFIBUS with several subordinate SPL couplings (sub-slots).
Example of an NCK parameterization
The following specifications are applied when it comes to further describing the NCK
parameterization of an F_SENDDP communication relationship.
