  1. 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 it’s 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.

  2. 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

  3. 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 3.36e+38

  4. 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) 2#1111111111111111 base 8 (octal) 8#177777 base 10 (decimal) 65535 (no 10# needed) base 16 ( hex) 16#FFFF • All of the above values are equal, they were just entered differently

  5. 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 it´s faster than a located variable. • Located: • Tag name with a hardware address. (State RAM.) • Not implemented in the code, so it´s 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.

  6. HW Variable List Program State-RAM FFB DDI ... 1:1 - 1:32 1:1 Start_PB 1x Logic_Interlock Time1 DDO ... 0:1 - 0:32 0:1 Motor_On 0x AVI ... FFB 3x Tank_Level 3:1 - 3:8 3:1 Time2 Level_Limit AVO ... 4x Valve_Ctrl 4:1 - 4:4 4:1 I/O Map Ranges Variable declarations Unlocated Variables Located Variables Concept V2.5 • Configuration, Addressing and Variable Assignments

  7. Concept V2.5 • Direct Addressing • Every direct address has a reference that indicates it’s 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

  8. Sort by: Name, Data Type, or Address Concept V2.5 • Variable Editor Unlocated Variable Located Variable # times used in program Data Type Identifier

  9. Click & Drag here Paste here Concept V2.5 • Create New Variables by Copying Rename the newly created variables

  10. Concept V2.5 • Search/Paste Dialog

  11. Concept V2.5 • Search/Replace Dialog

  12. Concept V2.5 • It is possible to change online without stopping the CPU: • Variable Names • Reference Addresses • unlocated to located addresses and vice versa • Changed variables can be downloaded into the Quantum PLC with Download changes.
