3.7.1.2
PROFINET Scanner Parameters (Redundancy Tab)
On the Redundancy tab, select whether or not the PNS is redundantly controlled.
Figure 56: PNS Parameters Redundancy Tab
When the PNS supports PROFINET System Redundancy and is configured in an HSB CPU Redundancy system,
the Programmer automatically selects redundant control by setting the Redundancy Mode parameter to
HSB
CPU Redundancy
.
When the PNS does not support PROFINET System Redundancy, or is not configured in an HSB CPU
Redundancy system, the PNS Programmer automatically selects simplex operation (non-redundant control) by
setting the Redundancy Mode parameter to
None
.
To configure a redundancy-capable PNS for simplex operation within an HSB CPU Redundancy system, change
the Redundancy Mode parameter on the Redundancy tab from
HSB CPU Redundancy
to
None
.
3.7.1.3
PROFINET Scanner Parameters (Media Redundancy Tab)
By default, the PNS is not set up for Media Redundancy. If the system will use Media Redundancy
(see Chapter 6, Redundant Media
for more information), open the
Media Redundancy
tab and select
Client
.
Figure 57: PNS Parameters Media Redundancy Tab
If the PNS will be a Media Redundancy Client, click on
Ring Port 1
and
Ring Port 2
to choose the module ports
that will be used.
