NETLink PRO ETH
43
The following screenshot shows that a variable named
‘MB0_over_NETLink_PRO’
now exists under the
‘NETLink_PRO’
connection.
If this variable is now included in the initial screen of the WinCC project, for
example, a connection will be established to the CPU with address 49 via the
NETLink PRO ETH to read or write marker byte 0 from this rack 0, slot 2.
Further variables of different types can, of course, be created and used
according to the same scheme.
It is also possible to create additional TCP/IP connections in order to
communicate not only with rack 0 / slot 2, for example, but also with rack 0 /
slot 3. However, all the communication must go via bus address 49.
