Check configuration
The PLC alarms of the drives must have an identical time stamp with the NC.
For the configuration in the hardware configuration, define the associated Siemens telegram
390 for the SINAMICS CU. The corresponding logical input and output addresses of this
communication interface are entered in the following machine data item:
● MD13120[n] CONTROL_UNIT_LOGIC_ADDRESS
● MD13120[1]...[5] are reserved for NX expansion modules.
Note
You can view these logical addresses in the HW configuration when configuring the
properties of SINAMICS components under "Details".
Procedure:
1. Check the logical address for SINAMICS CU in the "Commissioning" → "Machine data" →
"General MD" operating area and enter, for example, the following value:
MD13120[6] = 288
2. Press the "Reset (po)" softkey to accept the changed machine data.
This completes the commissioning of the PLC drives.
