Example

Determining slot addresses
After selecting the DP Slave "SINAMICS_Integrated" on the integrated PROFIBUS
"PROFIBUS Integrated: DP master system (3)" in the station window of HW Config, its
PROFIdrive message frame and associated slot addresses are displayed in the detailed view.
● Message frame 136: Drive
● Message frame 391: Control Unit
● Message frame 370: Infeed
The infeed slot addresses required for parameterization in the NC machines are:
● Input slot: Slot 31, address 6514
● Output slot: Slot 32, address 6514
Figure 13-18 Infeed PROFIBUS message frames
Setting NC machine data
● Input slots:
MD10520 $MN_PLCINTERN_LOGIC_ADDRESS_IN[ 0 ] = 6514
● Output slots:
MD10525 $MN_PLCINTERN_LOGIC_ADDRESS_OUT[ 0 ] = 6514
Controlling the ALM using FB390 "ALM_Control"
The SINUMERIK hardware PLC is connected to the CU320 of SINAMICS S120 through the
internal PROFIBUS. The ALM is connected to the CU via DRIVE-CLiQ.
In SINAMICS S120, a control and status message frame can be defined for each module (the
CU, ALM, motor modules, etc.). If this is performed for an ALM, this can be switched on and
off from the PLC user program.
