Connecting Sensors/Actuators
7.4 Safety- -related CPU- -CPU communication (F_DP communication)
Activation data
Every parameterizing data set can be separately activated using the enable screen
form.
Parameterizing data
The parameterizing data set of an SPL connection involves the following values:
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 reaction:
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.
Fault 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--con-
tiguous 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 para-
meters of the SPL connection are identical. As part of the F_DP communication,
these SPL connections are combined to form a single SPL connection communi-
cating via PROFIBUS with several subordinate SPL couplings (sub--slots).
