Parameterizing The F Master (Nck) - Siemens SINUMERIK 840D sl Function Manual

PROFIsafe communication
The principle of PROFIsafe communications between SINUMERIK 840D and the F
modules on the PROFIBUS DP is explained in detail below. This is based on the
transfer of the SPL output data $A_OUTSE/$A_OUTSEP to the F-DO modules:
The PROFIsafe layer creates a PROFIsafe telegram (F telegram) in each PROFI-
safe cycle with the ANDed SPL output data as F useful (net) data
and the backup data (CRC and the consecutive number) and transfers it to the
PROFIBUS layer via the DP data interface.
The PROFIBUS layer transfers a DP telegram with the PROFIsafe telegram
created by the F layer in each PROFIBUS cycle as DP useful data to the DP sla-
ves. This is independent of the PROFIsafe cycle.
Configuring/parameterizing
The configuration and parameterization needed to connect the F modules to the
external NCK/PLC-SPL interfaces entails the following steps:
1. Generating the configuration using SIMATIC STEP7.
2. Performing a standard SINUMERIK 840D sl commissioning (minimum require-
ment).
3. Loading the configuration and the PLC basic and user program modules into
the SINUMERIK 840D sl PLC.
4. Parameterizing the PROFIsafe-relevant SINUMERIK 840D sl machine data.
See Subsection 7.2.3 "Parameterizing the F master (NCK)".
7.2.3

Parameterizing the F master (NCK)

The F master is parameterized in the machine data of the NCK and comprises the
following sub-areas:
S PROFIsafe communication
– PROFIsafe address of the F master
– PROFIsafe clock cycle
See Subsection 7.2.4 "Parameterizing the PROFIsafe communication (NCK)".
S SPL-SGE/SGA interface
– PROFIsafe address of the F module
– F net data filter
– SGE/SGA assignment
SPL-SGE interface See Subsection 7.2.5 "Parameterizing the SPL-SGE inter-
face (NCK)".
