5 Configuration via the NETLink-S7-NET Driver
Once a NETLink
®
PRO Family has been selected in the ‘Set PG/PC
Interface’ window, it is possible to specify this access path more
precisely with the ‘Properties…’ button.
With the functionality behind the button ‘Diagnostics...,’ which is
visible when a NETLink
®
PRO Family is selected, it is possible to
read the bus configuration and scan connected nodes.
The properties of the access NETLink
®
PRO Family are divided
into three subareas:
• Bus settings
here it is possible to state the bus configuration (e.g. station
address) with which the NETLink
®
Switch will enter the bus
system (Section 5.1).
• Local connection (TCP configuration)
Here, you set the IP address via which the required connection
with the programmable controller will be established (Section
5.2).
The NETLink
®
Switch hardware can also be parameterized in
this window.
• Options
Here it is possible to change the language of the NETLink-S7-
NET driver and to read out the version information of the
driver (Section 5.3).
Two functionalities are implemented for diagnostics at the con-
nected bus:
• Bus members
a list of all active and passive nodes connected to the bus will
be displayed. By request the order numbers (MLFBs) will be
displayed also if this functionality is available by the nodes
(Section 5.4.1).
• Bus parameters
If possible, a list of all available bus parameters will be dis-
played (Section 5.4.2).
5.1 Bus settings
The NETLink
®
Gateway can be operated on three different bus sys-
tems: MPI, PPI, and PROFIBUS.
From the NETLink
®
Gateway user’s viewpoint, the three bus sys-
tems only differentiates by the transmission rates that can be se-
lected and the additional options which are explained here.
The bus configuration is passed to the NETLink
®
during the
runtime of the NETLink-S7-NET driver and is not stored in the
device.
It is possible to use NETLink
®
without providing bus-related in-
formation. In this case, NETLink
®
will independently attempt to
receive the transmission rates and the bus parameters from a mas-
ter CPU, and can then be operated without resetting the NETLink-
