Activation data
Every parameterizing data set can be separately activated using the activation
data.
Parameterizing data
The parameterizing data set of an SPL connection involves the following data
areas:
S Identifier:
-- DP_DP_ID:
-- Name:
S Connection number:
S Communication parameters:
-- I/O start address:
-- Monitoring time:
S Net data parameters:
-- SPL assignment:
-- F net data filter:
S Fault response:
-- Error response
-- Substitute values:
For SPL connections with the same identifier, all parameters identified with # must
be identical. In case of an error, Alarm 27305 "F_DP: Parameter MD %1[%2] < >
MD%3[%4]" is output.
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.
Fault responses
The system responses when a communication error occurs can be influenced by
the user by appropriately setting the machine data $MN_SAFE_RDP_ERR_REAC
and $MN_SAFE_RDP_SUBS or at a later time by programming the system
variables $A_FRDP_ERR_REAC, $A_FRDP_SUBS in the SPL program.
SPL couplings (sub- -slots)
Just the same as for PROFIsafe, also for F_RECVDP, only contiguous ranges of
SPL input data ($A_INSE[x] up to $A_INSE[x+y]) can be assigned to an SPL con-
nection. If the received F net data are to be transferred in several non--contiguous
SPL input data areas, then several SPL connections must be parameterized.
These are then designated using an identical identifier, communication parameter
and connection number, but different SPL couplings. As part of the F_DP commu-
nication, these SPL connections are combined to form a single SPL connection
communicating via PROFIBUS with several subordinate SPL couplings (sub--
slots).
