TAC Xenta 527-NPR
Security Router
03-00043-02-en
The TAC Xenta 527-NPR is a cost-effective and feature-enhanced version of the I/NET Net Plus Router. The TAC Xenta 527-NPR
carries out many of the functions of a host PC but at a controller level, which reduces any dependence on host computers. The NPR
deals with peer-to-peer point interaction, and manages and buffers events as necessary. All stored events and transactions are fully
protected against loss of power by onboard batteries. The Xenta 527-NPR only supports connections to I/NET networks. It does not
support LonWorks, or any other protocols.
This version of the Xenta 527-NPR introduces the ability to create segmented IP networks within an I/NET architecture. Encryption is
available at the Ethernet level for high security applications. Configuration is performed using I/NET, a serial terminal, or pre-defined
web pages. The Xenta 527-NPR does not require and is not supported by TAC XBuilder.

PERFORMANCE
I/NET Network
The TAC Xenta 527-NPR has the capabil-
ity to act as a Net Plus Router within that
system. The TAC Xenta 527-NPR has
been tested to deliver up to a maximum
of 15 I/NET alarms/events/transactions
per second or 1.3 million per day. The
maximum burst can be up to 40 per
second for 8 seconds.
The thruput for a single TAC Xenta 527-
NPR is determined by the amount of
polling the device is managing. Polling is
created mainly by
• Pointsonopengraphicspages
• Thescanrateofconnectionobjects
• Thevolumeofalarmandeventtraffic
The physical size of the connected I/NET
system is a factor in this but is not a pri-
mary limitation.
In some systems therefore more than one
TAC Xenta 527-NPR may be required to
handle the total system traffic.
