Communication PROFIBUS DP/PROFINET IO 10.2 Communication via PROFIBUS DP

Note

The factory settings are "ON" or "OFF" for all switches. With these two settings, the PROFIBUS address is set by parameterization.

Parameter p0918 is unique to the Control Unit (see Control Unit). The factory setting is 126. Address 126 is used for commissioning. Permitted PROFIBUS addresses are 1 ... 126.

If more than one CU is connected to one PROFIBUS line, the address settings must differ from the factory settings. Note that each address can only be assigned once on a PROFIBUS line. This can be achieved using the address switch or by setting parameter p0918 accordingly. The setting can be made by connecting the 24 V supply step by step and resetting p0918, for example.

The address setting on the switch is displayed in r2057.

Each change made to the bus address is not effective until POWER ON.

Device master file

A device master file provides a full and clear description of the features of a PROFIBUS slave.

The GSD files can be found at the following locations:

On the Internet: http://www4.ad.siemens.de/WW/view/de/113204

On the CD for the STARTER commissioning tool Order no. 6SL3072-0AA00-0AGx

On the CompactFlash card in directory \\SIEMENS\SINAMICS\DATA\CFG\

Commissioning for VIK–NAMUR

To be able to operate a SINAMICS drive as a VIK-NAMUR drive, standard telegram 20 must be set and the VIK-NAMUR identification number activated via p2042 =1. In this case, only the NAMUR GSD can be used.

Device identification

An identification parameter for individual slaves facilitates diagnosis and provides an overview of the nodes on the PROFIBUS.

The information for each slave is stored in the following CU-specific parameter: r0964[0...6] device identification

Bus terminating resistor and shielding

Reliable data transmission via PROFIBUS depends, amongst other things, on the setting for the bus terminating resistors and the shielding for the PROFIBUS cables.
