Controller
The controller is composed of a CPU with two serial communication ports, power supply, and a backplane
assembly. It incorporates a card rack that is capable of supporting up to 16 input and output modules that
can be mixed to satisfy the hardware requirements of a specific application.
Modules are available in ten different configurations to support both analog and digital inputs and outputs
of various types and signal levels.
Each module has a removable terminal block accepting #16 AWG wire.
An optional RS485 serial communication card that supports both slave data exchanges with a host PC for
centralized operation and data management and/or communications via a Modbus RTU master to other
Honeywell or 3
rd
party compatible products.
Operator interface
The operator interface uses a color graphic LCD display to provide a variety of screen presentations for
viewing control loops, setpoint programs, and other analog and digital status. Modification and
customization of the operator interface are performed using UMC800 Control Builder software.
With the software, data points can be identified (tagged) using eight character names. Once named, these
data points may be accessed by the operator interface using a standard set of display formats and a
predefined menu hierarchy.
Customized display access and the assignment of selected display screens to keyboard buttons may be
developed using Control Builder software. Selected screens such as bar graphs, trends, and overview
displays will require the user to specify the individual data points to be represented on the screen.
A menu selection allows the user to select from English, French, Italian, Spanish or German languages
.
Control Builder
A separate “Control Builder” configuration software program is used for UMC800 Controller and Operator
Interface configuration and operates on a Windows ’95, ‘98 or Windows NT-based PC. The software
program uses graphic symbols and line drawing connections to create custom control strategies.
All configuration is performed off-line (computer disconnected from the controller and operator interface).
The configuration is downloaded in a separate operation as a complete file through a dedicated RS-232
communication port on the controller. Once a configuration is installed into the controller and operator
interface, the Control Builder software may be used to monitor areas of the configuration to verify proper
operation.
Menus are provided in the software to allow selection of screens for the operator interface and to customize
screen access methods and operator keys.
Completed configurations are loaded into the control system using a dedicated communication port in the
controller or, optionally, via floppy disk from the operator interface.
Loop control
The UMC800 supports up to sixteen control loops with PID, ON/OFF, Carbon Potential, or 3 Position Step
control action. Control loops may be configured to operate independently or in cascade. Operator entered
setpoints may be limited by independent high and low limit values and setpoint rate of change limits are
available to protect critical products during process changes.
When Feedforward operation is applied, a separate Feedforward gain adjustment is available to tune the
loop for the appropriate Feedforward response.
