initial model file

The initial model file in the Design

Number of Hidden Neurons and Train

operations is an optional parameter. If the

architecture of the initial model file does

not match the required architecture, the

operation will still work. If there are too

many weights, the program simply

discards the excess weights. If there are

too few weights, the program randomizes

additional weights. As an alternative to

using an initial model file, select

RANDOM to use random weights.

input layer

The first layer of a neural net, which is

composed of input neurons.

input neuron

An element of the input layer, which

reads in a raw input value.

input/output (IO or I/O)

Signal reception and transmission, or

signal interfacing. Input, for a process

control device, involves accepting and

processing signals from field devices.

Output, for a process control device,

involves converting commands into

electrical signals to field devices.

input sample rate

The rate at which the data historian

sampled the input data. The rate times

the scan rate multiplier gives the rate at

which the intelligent sensor is to execute,

called the network execution rate.

insertion loss

The amount of loss when a signal goes

through a tap.

INSTCOMN table

Main index table for Table View.

Institute o f Electrical and Electronic

Engineers (IEEE)

An independent technical organization

that defines standards for the electrical,

electronic, and computer industries.

instruction

1. In data processing, a statement that

specifies an operation and values or

locations of its operands.

2. An individual function of a function

sequence table (FST), which is an

algorithm that runs under a logic control

point (LCP). Individual instructions are

entered on the ENVOXr LCP FST form

using the Instruction Editor. Instructions

are linked together to create a control

strategy.

See Command, Function Sequence

Table (FST), and Operation.

instrument function

Part of the tag number; indicates the

function performed by a device.

instrument function/group

Letter codes representing a set of related

instrument IDs. Loop numbering is

dependent upon instrument group, the

type of loop numbering, and the location

of a tag.

instrument ID

Consists of two or more identification

letters. The first letter (or instrument

group) is a general classification of what

a device does, and the subsequent

letters (or functional identifiers) specify

what the device does in more detail. The

instrument ID components have a

number of different naming conventions,

and IIS has standardized on the definition

above.
