Parameterizing The Spl-Sge Interface - Siemens SINUMERIK 840D sl Function Manual

Connecting Sensors/Actuators
7.2 Connecting I/O via PROFIsafe
Further, an attempt is still made to initiate the OB40 interrupt and to maintain PRO-
FIsafe communications.
The time up to initiating the next OB40 interrupt is displayed in the following NCK
machine data:
S MD 10099: $MN_INFO_PROFISAFE_CYCLE_TIME
(PROFIsafe, communications clock cycle)
If the PROFIsafe clock cycle is continuously exceeded and just not sporadically,
then the following alarm is displayed:
S Interrupt: 27256 "PROFIsafe actual cycle time %1 [ms] > parameterized cycle
time"

Parameterizing the SPL-SGE interface

A bitwise assignment can be made using machine data to better link the SPL inter-
faces to the net (useful) data of the F modules.
Note
The examples, now listed, to parameterize the SPL-SGE interface are based on
the following specifications:
F-DI module
– F address: 114 = 90H
– F net data length: 8 bytes
Machine data
– MD10386 $MN_PROFISAFE_IN_ADDRESS[5]
– MD13300 $MN_PROFISAFE_IN_FILTER[5]
– MD10388 $MN_PROFISAFE_IN_ASSIGN[5]
Assignment: F module to the F master
Important
Currently, only sub-slot [0] may be used.
F net data of an F-DI module is sub-divided into units each 32 bits. Each of these
32 bit units are known as sub-slots. This sub-division, for assigning the F-DI mo-
dule to the F master is expressed in the sub-slot address.
