Boot behavior of the F_DP communication

When the control boots, then the F_DP communication, i.e. the F_DP communica-
tion relationships of all parameterized SPL connections (F_SENDDP and
F_RECVDP) automatically boot and establish cyclic F communication with their
particular communication partner.
The boot state of the F_DP communication is represented in the output data of the
user interface (DB18) as follows:
S F_SENDDP (NCK)
-- $A_FSDP_ERROR[1...n] = 0
-- $A_FSDP_DIAG[1...n] = 0
-- $A_FSDP_SUBS_ON[1...n] = 1
S F_SENDDP (PLC)
-- FSDP[1..3] bzw. FSDP_HF[4..16]
-- .ERROR = FALSE
-- .SUBS_ON = TRUE
-- .DIAG = 0
-- .RETVAL14 = 0
-- .RETVAL15 = 0
S F_RECVDP (NCK)
-- $A_FRDP_ERROR[1...n] = 0
-- $A_FRDP_DIAG[1...n] = 0
-- $A_FRDP_SUBS_ON[1...n] = 1
-- $A_FRDP_ACK_REQ[1...n] = 0
-- $A_FRDP_SENDMODE[1...n] = 0
