You can establish the connections to the SINUMERIK NCUs (numerical control units) via standard interfaces of the computer or corresponding CP modules.

Additional Siemens software (e.g. SIMATIC NET or SIMATIC STEP 7) is needed for operation, in case you establish the connection to the control system via a SIMATIC NET communication card (CP) in the computer to an integrated Ethernet interface of the CPU (if available) or to a CP module in the PLC.

Note
	It is recommended carrying out the TCP/IP communication on a separate network segment to exclude a mutual influence by other network components.
