Software Product Description
PRODUCT NAME:

Power Demand Control for RSX-11 M, Version 1

SPD 15.75.1

DESCRIPTION:

MINIMUM HARDWARE REQUIRED:

The power demand applications software is a series
of tasks that run under the RSX-11 M real-time operating system. These tasks monitor electrical power
demand and shut off or throttle back selected equipment to reduce peak power requirements. Flexible
operation is provided by a large base of user-specified parameters.

Any valid RSX-11 M operating system configuration
which includes:

English-like operator commands are used on the operator terminal for dialogue with the system. Meter
and load status reports are available on request or on
a scheduled basis. Historical data can be recorded on
cassette for later play-back.
Equipment is shut down according to a user-specified
priority list, lowest priority first. Equipment will not be
shut down again before a user-specified cycle time in
order to prevent excessive on/off cycling. When
equipment is shut down, it remains off for a userspecified period of time. Up to 6 different off-times
may be specified for each load during the 24-hour
day. Operator override commands permit any load to
be removed from system control and later be returned to full system control.
If the system forecasts that the pre-specified target
demand value will be exceeded despite the maximum
effort of the system to shed all available loads, a
warning message will alert the operator to permit
manual control of loads.
Once the system parameters have been entered or
altered, a command can save the parameters on cassette. Several sets of parameters can be set up and
saved. Later, the parameters can be reloaded into the
system for quicker system start-up without re-entering the parameters.
A simulation mode provides a software simulated
power meter. Repeatable power peaks are generated
by the power meter and supplied to the system control programs. Parameters such as off-times and cycle-times can be "tried out" in simulation mode. Reports can be printed or data recorded just as with
actual power meter connections.
