7716
Process Control Unit
TAC’s Process Control Unit (PCU), part of the TAC I/NET
TM
family of
products, provides direct control and monitoring of process functions
from a “Peer-to-Peer” LAN-based controller.
02
TAC I/NET 7716 Process Control Unit
Features
These process functions include
environmental control, trending, energy
management, and process control, which
may be executed locally in a standalone
mode or “globalized” across the Token
Passing LAN. The 7716 PCU is appropriate
for commercial, institutional and industrial
applications.

PCU Features
•
direct digital Control (ddC)
Controller Design
The 7716 PCU hardware is based on a monolithic
board design, combining processing, memory,
communications and ield Input/Output (I/O)
functions on a single printed circuit board. The
controller features quick disconnect terminals,
downloadable irmware, an RS-485 LAN port,
one or two RS-232 ports, a TTL port for a hand
held console, and optional on-board modem
drivers. The inherent reliability of this monolithic
design is further enhanced with extensive transient
protection, automatic self-test features and a iber
optics communications option.
•
Both Adaptive and Self-Tuning PId Algorithms
•
Universal Inputs
– Pulse
– Analog
– discrete
•
Configurable outputs
– Pulse Width Modulation (PWM) Analog Control
– Form C relay discrete Control
– Floating Control
•
Peer-to-Peer Token Passing LAN Port, built-in
•
Automatic LAN reconfiguration upon any
fault detection
Control Functions
Direct Digital Control is provided by “Object
Modules” that are used to develop global logic
sequences. These Object Modules emulate
pneumatic /electronic components and may be
“linked” to create a wide variety of custom control
sequences. Object Modules are available for:
PID, Floating, High/Low Selector, 2 Position,
Relay (with timer), and Reset (dual input).
•
Automatic restart Procedure Upon Power
Loss/restoration
•
on-off-Auto Switches on all outputs
– Prewired for Status Feedback
– LEd Indicators for output Status
•
Look-Up Tables for each Input
– 20 Segment Curve Fitting
•
Analog Transducer Power Supply, built-in
Automatic Time Scheduling provides a full year’s
schedule, including multiple start/stop times,
special days and temporary inputs for each load.
•
Local Port for PC
•
Local Port for Auto dial/Auto Answer Modem
•
on-board Trending of all I/o Points
Automatic Temperature Control, working in
conjunction with Automatic Time Scheduling, self
adjusts the heating or cooling setpoint, providing
normal temperature control as well as setup/set
back control, including user-speciied deadbands.
•
Modular, object-oriented Programming
•
Extensive Math/Logic Package
•
resident Programs for:
– Environmental Control with ddC
– Energy Management
– Historical data Collection
Predictive Central Plant Start allows plant startup
based on inputs from one or more space sensors.

Features
(continued)
Demand Limiting continuously monitors the rate
of electrical power consumption and predicts
the demand during each demand interval. If
the predicted demand exceeds a preset level,
controlled loads are shed or control setpoints
changed in a user-deined priority sequence.
As peak demand passes and electrical power
consumption decreases, the controller restores the
loads or setpoints to their normal routines. Multiple
power meters are supported in each PCU with
multiple loads speciied for each meter. Maximum
Off, Minimum On-Off, and seven levels of shed
priority ensure eficient Demand Limiting, while
protecting environmental control objectives.
Dimensional Drawing
Calculated Points are used to perform special
calculations required by the system. Calculated
points allow development of “equations” using
math, logic, Boolean, time and other operators.
Event Initiated Control provides “IF-THEN-
ELSE” control sequences, with time delay options,
based on a state change or speciied state of
a point. Additional Functions include Runtime,
Consumption and Alarm Inhibit.
7716 PCU
High resolution Look-up Tables
Non-linear points may use a look-up table for
linearization. The table contains as few as two or
as many as 21 entries. Separation between entries
is user-deinable, allowing higher accuracy around
the primary area of interest. Look-up tables may be
used with linear or non-linear signals to clamp the
end points to a speciic value.
Downloadable Firmware
Complete executable software is downloaded
through a locally connected PC, LAN or a modem.

Online Editing Capability
The 7716 provides direct online edit capability
via a local, remote or portable PC for instant
modiication of all parameters. An operator with
the appropriate password authorization may
make changes online that are as simple as time
schedule changes or as comprehensive as chiller
optimization strategies. There is no need to
use archaic techniques that require compiling,
debugging or reloading the software. The operator
may observe the results of the changes instantly.
All operator entries on TAC I/NET PCs use menus
with self-prompting, ill-in-the-blank editors.
Context sensitive help screens are available on
the PC with the touch of the “F1” key. There is
no need to learn a custom computer language or
generate programming statements.

Trend Sampling
Trend Sampling is accomplished within the
controller independent of any PC workstation.
Each PCU can trend all connected points and can
store up to 1440 samples of critical points within
the PCU. These samples can be archived to
multiple local or remote PC workstations and used
to generate custom reports.
