    The remaining steps for commissioning the SINAMICS HLA is described below. System data block (SDB) Before you can output an analog setpoint via a SINAMICS HLA, you must load a special system data block (SDB) into SINUMERIK 828D. This allows you to use PROFIBUS telegram 166 for commissioning. 3.1.1 Installing the SDB 1.
