PROFINET Scanner Parameters (Settings Tab)
Figure 55: PNS Parameters Settings Tab
Inputs Default: Choose whether the RX3i CPU will set inputs from any modules in the PNS
module’s remote node to Off or Hold Last State in the following cases:
• The PROFINET Controller is not operational or has been removed.
• The PROFINET Controller cannot communicate with the scanner due to cable or
network configuration issues.
• The PNS is not able to scan the I/O module in its remote node.
Input Status and Length: The address in reference memory for the 32 bits of status data
associated with the PNS. The address can be assigned to valid %G, %I, %Q, %T or %M memory
or Symbolic bits. The default value is the next available %I address. Refer to the VersaMax
PROFINET Scanner Manual, GFK 2721, for definitions of the PNS input status bits.
Output Status and Length: The address in reference memory for the 32 bits of output
control data associated with the PNS. The address can be assigned to valid %G, %I, %Q, %T or
%M memory or Symbolic bits. The default value is the next available %Q address. Refer to
the VersaMax PROFINET Scanner Manual, GFK-2721, for definitions of the PNS output
control bits.
I/O Scan Set: Specifies the I/O scan set to be assigned to the PNS. Scan sets are defined in
the CPU’s Scan Sets tab. The valid range is 1 through 32; the default value is 1.
PROFINET Scanner Parameters (Redundancy Tab)
On the Redundancy tab, select whether 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.
