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:
● F_DP communication relationship
The following F_DP communication parameters are defined using the F_DP communication
relationship:
-
-
– -
– -
-
-
● SPL coupling
The SPL coupling is used to define which F-data signals of the F-telegram are to be mapped
to which SPL inputs ($A_INSE). Several SPL couplings can be parameterized for one SPL
connection.
Note:
The interpretation and processing of the F-net data signals are realized via the PLC and
NCK-SPL, and are the exclusive responsibility of the user or SPL programmer.
● Connection number
A parameterizing data set is assigned to an SPL connection using the connection number.
An SPL connection is defined in a parameterizing data set. For SINUMERIK 840D sl, 16
parameterizing data sets are available for F_RECVDP; as a consequence, 16 different SPL
connections, designated using 16 identifiers (DP_DP_ID), can be parameterized in the F-DP
communication relationships. In case of an error, Alarm 27306 "F_DP: Max. number of active
SPL connections (%1) for %2 exceeded" is output
SPL input data ($A_INSE) can only be assigned to an SPL connection in the parameterizing
data of the SPL coupling as contiguous range. If the SPL input data, which are required for an
