Receiver F_Recvdp - Siemens Sinumerik 840D sl Function Manual

Connecting Sensors/Actuators
7.4 Safety- -related CPU- -CPU communication (F_DP communication)
System variable: Diagnostics data, $A_FSDP_DIAG
System variable $A_FSDP_DIAG[1...n] is used to signal the cause of the commu-
nication error determined by F_SENDDP.
The system variable $A_FSDP_DIAG is not cyclically compared with the corre-
sponding PLC variables FSDP[1...16].DIAG.
Comparison, NCK system variable / PLC variable

Receiver F_RECVDP

In order to transfer SPL output data from an F--CPU to a SINUMERIK 840D sl
using F--DP communication, an SPL connection must be parameterized. This
connection comprises the following:
S F_DP communication relationship
The following F_DP communication parameters are defined using the F_DP
communication relationship:
-- Identifier (DP_DP_ID) and connection name
-- Communication parameters:
-- I/O start addresses (LADDR)
-- Monitoring time (TIMEOUT)
-- Error response (ERR_REAC)
-- Substitute values in the case of an error (SUBS)
