Concept V2.5

Concept V2.5

• Lesson 12 Objectives
• After completing this lesson, the learner will
  be able to
• Describe the difference between Located and
  Unlocated Variables.
• State the rules for Variable naming
• Use the Variable Editor to create and or delete
  Variables.
• Lesson Overview
• Concept Software uses the idea of named
  Variables and Constants in its programming
  structure in order to contain global data that
  needs to be passed between objects. The use of
  these named Variables eliminates the need to
  physically join objects together through the use
  of links.
• This lesson will explain Variables and Data
  Types, the naming of Variables, hardware
  addressing and the difference between using or
  not using hardware addresses with Variable names.

Concept V2.5

• Each Variable has to be declared with the
  Variable Editor before using it
• Either independently with ? Project ?
  Variable declaration F8
• Or during programming with a double-click on an
  input / output assignment.
• A data type must be assigned to each Variable.
  CONCEPT software provides elementary and derived
  data types

Concept V2.5

• Common Data Types and Ranges
• BOOL Must be a ON ( 1 ) or OFF ( 0 )
• WORD Represents a bit string 16, meaning the
  length of data is 16 bits.
• INT Represents an integer value. The range of
  values are -32768 through 32767
• UINT Represents an unsigned integer value. The
  range of values are 0 through 65535
• REAL Represents a floating point value. The
  range of values are 8.43e-37 through 3.36e38

Concept V2.5

• Entering Literal Values
• Literal values are used to assign values to pins,
  or to assign constants to variables, and are not
  meant to be changed by the program.
• You can enter literal values as
• base 2 (binary) 21111111111111111
• base 8 (octal) 8177777
• base 10 (decimal) 65535 (no 10 needed)
• base 16 ( hex) 16FFFF
• All of the above values are equal, they were just
  entered differently

Concept V2.5

• Variable names
• Max. length 32 characters, may start with number
• Unlocated
• Tag name without a hardware address.
• Implemented in the code, so its faster than a
  located variable.
• Located
• Tag name with a hardware address. (State RAM.)
• Not implemented in the code, so its not as fast
  as a unlocated variable.
• Constants
• Used to define value to a tagname, e.g., Hi_Temp
  103.7
• They cannot be located.

Concept V2.5

• Configuration, Addressing and Variable Assignments

7
Concept V2.5

• Direct Addressing
• Every direct address has a reference that
  indicates its position in the sequence and
  whether it is an input address (read only) or an
  output address (read / write).
• 0x / QXx area bit outputs (discrete),
  example 1 000001 is discrete Output
  1 example 2 QX00001 is Output Bit 1
• 1x / IXx area bit inputs (discrete),
  example 1 100017 is discrete Input
  17 example 2 IX00017 is Input Bit 17
• 3x / IWx area register inputs,
  example 1 300300 is register input
  300 example 2 IW000300 is Input Word 300
• 4x / QWx area register outputs,
  example 1 400029 is register output
  29 example 2 QW00029 is Output Word 29
