• maintains a copy of the most recent 8000 events,
• sends the events to master station(s),
• optionally sends the events to window annunciator(s), and
• optionally generate IRIG-B 1
One or more event acquisition device(s) are always part of an SER system.
1.1.2 Master Station
The master station(s):
• receives events 2
from the event acquisition devices (e.g. X501NET),
• stores the events on the database server, and
• provides a user interface to the SER system.
1.1.3 Database Server
The database server maintains the event history. It is written to by the master station(s) can be
accessed by the master station(s) and user work station(s).
1.1.4 User Workstation
User workstations allow plant personnel access to the event status and history. They also provide
a interface to configure the X501NET(s),
1.1.5 Window Annunciator
A window annunciator (such as the Ronan X110) is a display device that shows events and
process status by lighting individual windows. A window annunciator provides plant operators
with an instantly identifiable view of plant status and can save critical seconds when problems
occur.
1.1.6 Network Connection (LAN/WAN)
The network connects all of the parts of the SER system. Logically, the network is always the
same, it simply passed messages between the components of the SER system. In physical
implementation, the network is the most variable part of the SER system. It can be as simple a
single LAN or as complex as a set of LANs interconnected by the both public (e.g. world wide
web) and private data networks.
1.2 Getting Started
To get started using the X501NET configuration program you need a computer with web
browser
3
attached to the same LAN as the X501NET. Put the address
4
of the X501NET that you
1 IRIG-B120.
2 This function is called an Event Producer by IEC 60870.
