Siemens D410 appendix Expanding a message frame, Profibus message frame

Commissioning (software) 4.6 Using drive-related I/Os by SIMOTION

4.6.5Expanding a message frame

The message frame extension extends existing standard message frames (e.g. axis message frames) with additional process status data (PSD). These additional PSDs are then interconnected using BICO (e.g. to an actual speed value or to the status of a digital input).

A message frame extension is then the preferred variant when I/Os are to be distributed between SIMOTION and SINAMICS and, for example, an axis view is preferred (drive- related I/O should be appended to each axis message frame).

Proceed as follows:

1.Insert a drive using the Drive Wizard and select PROFIBUS (drive), e.g. "standard message frame 103", for process data exchange.

2.Double-click the "Configuration" entry below "SINAMICS Integrated" in the Project Navigator in order to open the "PROFIBUS message frame" tab.

The tab contains the default length of I/O data for the drive you inserted. As the addresses of I/O data have not yet been transferred to HW Config the default entry "???" is set.

3.Select the row of the object of which you want to expand the message frame.

4.Click "Add line" and select the "Message frame expansion" option in the menu shown.

A new line which contains the message frame expansion is inserted below the current line.

5.Enter the "length" for the number of PSDs by which the message frame is to be extended in the Input data and Output data columns.
