NETLink PRO ETH
41
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 address.
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 the CPU with bus address 49 but also with other
CPUs.
8.2.2
Use of rack/slot mode
For the basics of rack/slot mode at the NETLink PRO ETH end, see Section
8.1.4.2.
To parameterize a RFC1006 link in WinCC, a new TCP/IP link must first be
created in the
‘SIMATIC S7 PROTOCOL SUITE’
. Here, this connection is
called
‘NETLink_PRO’
.
