  1. 2-Introduction to the programming Logical controllers' programming • To program means to order with clarity a group of instructions that step by step they execute operations. . • That group will have to be a send to the controller in a language structured by form to be interpreted by the Central Unit without ambiguities. • Everything it should pass as if we taught to a human being the acting of the same tasks. 2- Programming

  2. 2.1- Basic instructions Logical controllers' programming LOAD - LD- It begins a line or logical block with open contact.

  3. LOAD NOT -LD NOT- Logical controllers' programming It begins a line or logical block with closed contact. 2.1- Basic instructions

  4. AND -AND- Logical controllers' programming It accomplishes one AND logical with the specified operator. 2.1- Basic instructions

  5. AND NOT -AND NOT- Logical controllers' programming It accomplishes one AND logical with the inverse state of the specified bit. 2.1- Basic instructions

  6. OR -OR- Logical controllers' programming It accomplishes a OR logical with the specified bit. 2.1- Basic instructions

  7. OR NOT - OR NOT – Logical controllers' programming It accomplishes a OR logical with the inverse of the state of the specified bit 2.1- Basic instructions

  8. OUT -OUT- Logical controllers' programming It makes the exit for the specified bit. 2.1- Basic instructions

  9. OUT NOT -OUT NOT- Logical controllers' programming It makes the inverse of the exit of the specified bit. 2.1- Basic instructions

  10. END -FUN (01)- Logical controllers' programming It is obligatory the use of this instruction in the end of the program. It is Without this instruction the program it will never be executed. 2.1- Basic instructions

  11. 2.2- Simple Diagrams Introduction of simple programs Logical controllers' programming Example 1 Ladder Diagram Statement List

  12. Introduction of simple programs Logical controllers' programming Example 2 Ladder Diagram 2.2- Simple diagrams Statement List

  13. Introduction of simple programs Logical controllers' programming Example 3 Ladder Diagram Statement List 2.2- Simple diagrams

  14. 2.3- Complex Diagrams AND LOAD Logical controllers' programming It accomplishes one AND logical among 2 blocks. Ladder Diagram Statement List

  15. OR LOAD Logical controllers' programming It accomplishes a OR logical among 2 blocks. Ladder Diagram Statement List 2.3- Complex diagrams

  16. 2.4- Temporary memory It retains the logical information (0 ou 1), during the treatment of the mesh where he was generated. Logical controllers' programming Ladder Diagram Statement List
