The following additions / modifications were performed since 2004 version:
- Multiple Remote Unit Windows capability was added to RUEX. Each
remote unit can now be assigned as many windows as needed. This is to accommodate
remote units with large number of I/O
points, so the latter can be displayed
properly.
- DNP 3.0 Protocol implementation was completed. A standard driver
for DNP devices is now available, offering standard DNP functionality.
Dedicated drivers, specific to non-compliant equipment are created as needed
by deriving them from the standard driver, and adjusting them accordingly.
- MODBUS Protocol handling was updated and reorganized. A standard
driver for MODBUS devices is now available, offering standard MODBUS
functionality. Dedicated drivers, specific to non-compliant equipment are
created as needed by deriving them from the standard driver, and adjusting
them accordingly.
- Double Poll command was added to RUEX and
MREX. RUEX also has a
parameter specifying time delay between the two polls. When double polling
an RUEX remote unit or an MREX meter, the first poll is followed by a delay,
then another poll is generated automatically.
- All WebLink Components were updated (Manager, Publisher, and
Service):
- To make them less cryptic, system components on the left (Selector) side of web pages were
renamed from RUEX, LMEX, CCEX, and MREX to SCADA,
Load Management, Capacitor Control, and Meter Reading,
respectively.
- The left (Selector) side of web pages now fully expands upon first
entry, displaying all published NTMC objects at once. This minimizes the number of mouse clicks needed to access the sought
information.
- Security rules were further tightened, while leaving administrative
accounts intact with all privileges.
- Load management waiver status is now reported on every Load Management
page, including individual load
points.
- For every load point LMEX can be programmed to report load state
together with Load management waiver status as a single value. This can
be used to generate e-mails when that load changes its 'value', i.e.
either load state or waiver status, and send them to load point's
owner(s).
- 'Frozen' Operations mode was added to LMEX load points. Load points in
'frozen' mode are ignored by LMEX algorithms just like load points in
'manual' mode. On the other hand, load points in 'frozen' mode can be
manipulated by authorized individuals via the web, while loads in
'manual' mode can not. Details of 'frozen' mode functionality can be
found here.
- Load point ON / OFF states are now color coded. Colors selected come
from NTMC color databases. The values of the latter are defined by NTMC
operators.
- Number of points in the graphs is now determined by the relevant
parameters in NTMC. For example, the RUEX Analog Point
'Number of
Readings' parameter is used to determine the number of points when that
analog point values are plotted on the web.
- Double Poll buttons were added to web pages displaying RUEX remote
units and MREX meters. When double polling an RUEX remote unit or an
MREX meter, the first poll is followed by an operator specified delay,
then another poll is generated automatically.
- IP Addresses of web browsers interacting with NTMC are recorded in
NTMC event log files when users issue commands via those browsers.
- AOT Accumulation - parameter
was added to RUEX control
points. When Disabled, control point's Accumulated Off Time (AOT)
is not updated at the time of transition from OFF to ON state. At that same
time parameter's value is automatically reset to Enabled. This enables operators to turn off AOT accumulation when control point is set to
OFF for other than normal operational reasons. Since LMEX
load points and CCEX
capacitors are mapped to RUEX
control points, this functionality extends to Load Management and Capacitor
Control components.
- All NTMC Components - can now run on windows accounts with
non-administrative privileges. This makes installation of NTMC easier on LANs
where there are tight security arrangements in place. This modification does
not affect NTMC native security.
- Remote Client - was modified as follows:
- Data recording files (current, and
archived) can now be viewed remotely as well.
- Windows accounts on control room and remote computers no longer
have to match either by name, password or privileges. This makes
installation of Remote Clients easier on LANs where there are tight
security arrangements in place. This modification does not affect NTMC
native security.
- IOEX - now displays connected clients and servers. Control room IOEX displays
connected Remote Clients by their respective IP addresses, while Remote
Client IOEX displays control room machine by NetBios name or IP address,
depending on the settings.
- Configuration File Printing - was added to MCED.
