Sender F_Senddp - Siemens SINUMERIK 840D sl Function Manual

By creating a new connection, the addresses for the net data and acknowledgment telegram
are automatically parameterized. The parameterized addresses should then be entered in
MD13334/13344 $MN_SAFE_SDP/RDP_LADDR.

Sender F_SENDDP

In order to send SPL output data ($A_OUTSE) from one SINUMERIK 840D sl to another F-
CPU using F_DP communication, an SPL connection must be parameterized. An SPL
connection comprises the following:
● F_DP communication relationship
The parameters of the F_DP communication are defined using the F_DP communication
relationship:
-
-
– -
– -
-
● SPL coupling
The SPL coupling is used to define which SPL outputs ($A_OUTSE) are mapped to which
net data signals of the F-telegram.
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_SENDDP. This means that a maximum of 16 SPL
connections, identified using 16 different identifiers (DP_DP_ID) can be simultaneously active.
In case of an error, Alarm 27306 "F_DP: Max. number of active SPL connections (%1) for %2
exceeded" is output
SPL output data ($A_OUTSE) can only be assigned to an SPL connection in the
parameterizing data of the SPL coupling as contiguous area. If the SPL output data, which are
required for an SPL connection, are not contiguous, but are distributed over several areas,
then several SPL connections must be parameterized. These SPL connections are designated
using identical F_DP communication relationships and connection numbers, but different SPL
couplings. The parameterization of
designated as sub-slots within the framework of PROFIsafe (see Chapter "parameterizing the
SPL-SGE interface (Page 196)").
The number of SPL couplings per SPL connection can be freely parameterized within the
framework of the number of parameterizing data sets that are available. The following options
are available to parameterize SPL connections and SPL couplings for each SPL connection:
● SPL connections: 1 up to a maximum of 16
● SPL couplings per SPL connection: 1 up to a maximum of 16, whereby the sum of all SPL
couplings of all SPL connections can be a maximum of 16
