4Ć7Device Definition Configuration

Original Ć June 1990 CE4.2:CL6211

Strategy Ċ The strategy field is a 12 character text field that can be used

to help group points together. For example, if the plant consists of a

boiler, a reactor, and a tank, the strategy field of each point could be set

to either "Boiler", "Reactor", or "Tank". This data is not checked or

processed in any way, but points can be sorted by the strategy field.

4.2.1 FST Registers

This portion of configuration defines the general purpose registers to be

used by the function sequence table (FST) of the controller.

Number Ċ This is a read only field that indicates the number of the

general register within the controller. For the computing controller this

field is 1 through 24. For the interactive controller this field is 1 through

49.

length. Since each register is identified by its name, each name must be

unique for the controller.

Type v Ċ The register types are MONITOR, REFERENCE, or MONITOR

REFERENCE. This determines the kind of access allowed to the register

by the function sequence table (FST) of the controller or by the operator

interface device (console or hand-held tuner). Table 4Ć1 lists the three

types of registers and shows the access allowed for each. For example,

a monitor register can be written into (data store) or read by (data load)

the controller, but the operator interface can only read it.

Monitor x x x Ċ

Reference x Ċ x x

Monitor-Reference x x x x

Analog Ċ The initial analog value of the register. This value can be any

valid floating point number.

Discrete Ċ The initial discrete value of the register. Choose between

ON and OFF. ON corresponds to a high value or a 1, and OFF

corresponds to a low value or a 0.
