2、r see Figure 1 designed to address the analog and digital control requirements of small unit processes. With up to 16 analog control loops, four set point programmers, a set point scheduler, and an extensive assortment of analog and digital control algorithms, the UMC800 is an ideal control solution
3、 for furnaces, environmental chambers, ovens, reactors, cookers, freeze dryers, extruders, small boilers, and other processes with similar control requirements.Accommodating up to 64 universal analog inputs, 16 analog outputs, or 96 digital inputs or outputs, the UMC800 provides the appropriate bala
4、nce of input and output hardware for these smaller unit processes.Split architectureThe UMC800 uses a split architecture that separates the control functions from the operator interface functions to provide greater installation flexibility.ControllerThe controller is composed of a CPU with two seria
5、l 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
6、 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 co
7、mmunications via a Modbus RTU master to other Honeywell or 3rd party compatible products.Operator interfaceThe 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. Modificat
8、ion 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
9、 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
10、 be represented on the screen.A menu selection allows the user to select from English, French, Italian, Spanish or German languages.Control BuilderA separate “Control Builder configuration software program is used for UMC800 Controller and Operator Interface configuration and operates on a Windows 9
11、5, 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 a
12、s 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 softwar
13、e 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 cont
14、rolThe 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 ch
15、ange 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.When Ratio control is applied, a ratio and bias adjustment are provided.
16、When used with the supplementary loop control blocks, digital inputs may be used to set control mode, select the setpoint source, change control action, and perform other discrete actions.A status block provides digital outputs to facilitate integrating loop operation with other functions in the controller.When configured for dual output heat/cool , each output may be directed to diff
