RS Logix 5000 (Allen Bradley PLC) Types of Tags

Types of Tags in RSlogix 5000

1. Base:-

    A base tag is one type of memory tag. A tag that actually defines memory where the data is stored.

2. Alias:-

    Alias is one type of physical tag. Alias tag is a human-friendly name for a physical memory location.

3. Produced:-

    - If we send data from one PLC to another PLC then the Produced tag is used. 

    -Multiple controllers can simultaneously consume (receive) the data. A produced tag sends its data to one or more consumed tags (consumers) without using logic.

4. Consumed:-

     -If we receive data from one PLC to another PLC then the Consumed tag is used.

     -The data type of the consumed tag must match the data type (including any array dimensions) of the produced tag. 

5. Module defined tag:-

    - A module defines a tag that should indicate a set of a tag to be automatically added by the module implements.  

    

6. Pre-defined tag:-

    - There are inbuilt tags in software is also known as pre-defined tags. It is like CU, CD, TT, etc.

7. Program tag:-

    - Program tags are used only in one program. At a time in one program.

8. Controller tag:-

     - It is also called Global tags. These tags are used in another program that's why we called global tags. The controller tag applies to the entire controller and can be used by all programs.

9. ADD-ON define tag:-

    - It is one type of Block in which we make a program and we use many times in our program. (ladder logic → block)

10. User define tag:-

      - It is such as based on our requirement we make an own tag.
