Configuring the NCU
3.2 Insert NX module
Result
The NX module has been inserted into the project and connected to an NCU.
Note
Handling the NX
● If NX modules were connected with the NCU and the NCU is subsequently deleted, the NX
modules are kept in the project as unconnected slave modules. They can be subsequently
assigned to another NCU. The parameter settings of the NX modules are retained.
● If the DP address of the NX is specified, then the I/O addresses matching the default setting
on the NCK side are entered.
