Note
On SINUMERIK 840D, SIMATIC line 0 is allocated for the SINUMERIK components.
In this line stretches to:
• Slot 2: the integrated PLC with the different bus systems
• Slot 3, empty
• Slot 4: the NCK 840Dsl. The properties (I/O-address 256, process alarm) of the NCK
must not be changed, as process interrupts (e.g. auxiliary functions) of the NCK to PLC
may, in this case, no longer function.
• Slot 5: the integrated Ethernet CP 840Dsl
• Slot 6: the integrated HMI 840Dsl
The integrated drive is linked on the internal PCI bus (PROFIBUS protocol).
Currently, this bus does not support I/O access, and SFCs are not supported for this bus.
If you are using a different NCU, you can change the NCU using "drag & drop". The settings
remain unaffected. When using the program "Starter" the icon "SINAMICS_in_NCUxyz" is
also to be deleted and created again after the exchange of the NCU in the SIMATIC
Manager.
