Nck--Md, That Are Read From Safety Integrated - Siemens Sinumerik 840D sl Function Manual

Data Description
8.3 NCK- -MD, that are read from Safety Integrated
8.3 NCK- -MD, that are read from Safety Integrated
The safety software reads the following NCK machine data. To a large extent,
these machine data are not calculated into the checksums, as they do not have
any direct safety--relevant significance, or as a consequence of changing this data,
the safety--relevant data is changed, which in turn, is calculated into the checksum.

Use
to determine the monitoring clock cycle;
as time basis for position controller based monitoring
times
to distribute the SI monitoring channels to various
position control clock cycles
as time basis for IPO--based monitoring times
Defines as to whether a PROFIdrive drive is invol-
ved.
to determine access to the interface to the DRV; to
determine the drive module type
