Assignment Of The Drive Data Using Do Variables - Siemens SINUMERIK 840D sl Operating Manual

as article number and component type. The structure with generalized drive data is also
specified.
Finally, the package processing requests the SINAMICS to check this data based on the
currently available configuration and to customize it appropriately, i.e. define the DO or
component status. SINAMICS has in the result a customized target topology (p9903) and
customized DOs for the specified components.
The DO parameters are customized by SINAMICS with the factory settings, values exported
from the components or calculated values. All this data is backed up in the drive data archive.
Because at this time components not yet present in the structure have already been created,
the associated user data can be added to the step tree using manipulation tasks. As an
alternative, for example with DQI/SMI motors, export of the data from the electronic rating plate
with the motor type or encoder type selection can be forced after activation.

Assignment of the drive data using DO variables

Immediately after the "Automatic configuration" or after the "User-specified topology", the
physical drives have been assigned to the data in the archive structure. The DOs, however,
are not yet assigned to the technological drive and thus to the correct NC axis.
If optimized drive, motor or encoder data has been configured in a CMC package for a DO, it
must be known to which physical DO this technological data must be assigned. This means
that the path address of this DO must be known. The data is assigned using DO variables.
Diff
When configuring a package in production preparation, SINAMICS data of the modular
modules is extracted once as master data to ASCII files from drive archives of one or more
commissioned base machines with the comparison component Diff (e.g. drive data, motor
data, encoder data of the various axes, line module data, etc.). Appropriate filter settings mean
this data no longer contains any topology-specific component numbers when exported.
When exporting, Diff writes a section in front of the data that provides a reference to a topology-
specific PS file in the drive data archive. This reference in the section is a short form of the
path, e.g. [B3_S3_PS5] instead of [BUS3.DIR\SLAVE3.DIR\PS000005.TEA].
These modular data sets can be maintained and managed in freely selectable folder structures.
Expert
When configuring in Expert , the topology-specific path data can be replaced by symbolic,
topology-independent path data using a DO variable, e.g. [$(Up.doVar.psPath)]. By assigning
the drive-specific DO variables to a SINAMICS-DO and the associated simultaneous value
assignment of the DO variables using the package during runtime, the DO variable has a
defined value and thus also a defined path. The assignment of the DO variables to a SINAMICS-
DO can be done manually at runtime in a dialog or in advance during the configuration of the
comparison or user-specified topology. With this method, topology-independent SINAMICS
parameters (master data) can be flexibly and easily assigned to each DO, regardless of where
the drive-specific DO was placed in the SINAMICS group for the current machine.
