3 Setting up functions
3.4 Fault Services
The contents of the absolute variable addresses are completely overwritten with
the information specified here. Individual bits are written selectively. Individual bits
can only be written as bytes. For this purpose it is possible to determine whether a
bit is to be set to 1 or 0, or is to remain without an entry as it currently appears in
the PLC.
SINUMERIK Integrate ensures that a variable that is configured as an absolute
address is always written as a complete entity (not byte-by-byte or bit-by-bit).
Description of the "Upload NC status data" function
Use the diagnostic action "Upload NC status data" to upload the NC status data to
the server upon an event.
This action type has no configurable parameters.
In the column with the paper clip, the NC status data can be marked for sending as
an attachment for a notification of the workflow for this control monitor.
Description of the "Execute and upload PLC trace" function
This action can be used to record the PLC variables status on a cycle-specific
basis, and display them synchronously via the server for comparison. Recording is
started with the trigger event of the control monitor. Recording is completed
following the number of PLC cycles to be configured. A special feature is the option
of specifying the number of recording cycles from the time before the trigger event
that shall be included in the recording.
Note
Since status recording can be initiated by any control monitor trigger, it is possible
that this trigger is initiated repeatedly within the programmed recording time.
SINUMERIK Integrate ensures that the recorded data is captured from the first
trigger until the end of recording and, provided that it is not overwritten in the DB
interfaces of the PLC, until SINUMERIK Integrate has fetched the data and stored
it on the server.
If a trigger subsequently occurs within the recording time for the pre-trigger,
recording is still carried out, but the pre-trigger status number is accordingly
lower.
