The configurable parameters are as follows:
● Multicast Address: Use this field to configure the multicast destination address. All DANPs in the network
must be configured to operate with the same multicast address for the purpose of network supervision.
●
Node Forget Time: This is the time after which a node entry is cleared in the nodes table.
● Life Check Interval: This defines how often a node sends a PRP_Supervision frame. All DANPs shall be
configured with the same Life Check Interval.
5.8.10 HSR CONFIGURATION
To view or configure the HSR Parameters:
1. Click the PRP/HSR Config button. The HSR Config screen appears.
2. To view the available parameters in the board that is connected, click the Retrieve HSR Parameters from
IED button.
3. To change the parameters, click the Set Parameters button and modify their values.
If you need to restore the default values of the parameters, click the Restore Defaults button.

Life Check Interval: This defines how often a node sends a PRP_Supervision frame. All DANPs must be
configured with the same Life Check Interval.
● Proxy Node Table Forget Time: This is the time after which a node entry is cleared in the ProxyTable
●
Proxy Node Table Max Entries: This is the maximum number of entries in the ProxyTable
● Entry Forget Time: This is the time after which an entry is removed from the duplicates
●
Node Reboot Interval: This is the minimum time during which a node that reboots remains silent
5.8.11 FILTERING DATABASE
The Filtering Database is used to determine how frames are forwarded or filtered across the on-board Ethernet
switch. Filtering information specifies the set of ports to which frames received from a specific port are forwarded.
The Ethernet switch examines each received frame to see if the frame's destination address matches a source
address listed in the Filtering Database. If there is a match, the device uses the filtering/forwarding information for
that source address to determine how to forward or filter the frame. Otherwise the frame is forwarded to all the
ports in the Ethernet switch (broadcast).
General tab
The Filtering Database contains two types of entry; static and dynamic. The Static Entries are the source addresses
entered by an administrator. The Dynamic Entries are the source addresses learnt by the switch process. The
Dynamic Entries are removed from the Filtering Database after the Ageing Time. The Database holds a maximum
of 1024 entries.
1. To access the forwarding database functions, if required, click the Filtering Database button in the main
window.
2. To view the Forwarding Database Size, Number of Static Entries and Number of Dynamic Entries, click Read
Database Info.
3. To set the Aging Time, enter the number of seconds in the text box and click the Set button.
Filtering Entries tab
The Filtering Database configuration pages are used to view, add or delete entries from the Filtering Database. This
feature is available only for the administrator. This Filtering Database is mainly used during the testing to verify the
