SMX Programming Manual for the SMX Module - OEM Automatic AB

Preparing the measurement
Choose the desired measuring scheme first!
In case of a speed oriented measurement the current recording time for the
corresponding axis is displayed on the X-axis. The measuring data for the graph are
read by the module, standardized and displayed with the correct time reference. The
recording memory is approx. 15 minutes.
The measuring process is automatically stopped when the buffer memory is full. The
previous measurement is automatically saved under "ScopeTempData.ScpXml".
With position oriented measurement the configured measuring range of the set axis
is displayed on the X-axis. Cursor 1 is in "Actual Position" of the axis and is
continuously updated via the data link. Cursor 2 can be displaced as required for the
determination of data.
Note: When changing the scheme, any recorded data from previous measurements
will be lost.
When changing the dialog size the display data must be rescaled. This requires
position oriented measuring and resetting the data buffer (SSX).
"Start" measurement
The control button "Start" is only available in case of an active connection to the
SMX-system. After clicking on this control button the data will be cyclically transferred
to the buffer memory and displayed in the diagram from left to right. Active recording
can be stopped with the "Stop" control button.
"Stopping" a measurement and viewing data
After completion of the measurement the data can be analysed by moving the slide
controllers accordingly.

Functionality
Recording of scaled position values of system A
and system B over the course of time.
Recording of process values for speed and
acceleration over the course of time.
Note:
Internally the position value of system A is used to generate
the process value for the position.
