  1. Rockwell Automation Hands-On Seminar Series

  2. SLC 500 BASIC LADDER INSTRUCTIONS

  3. Advanced Instructions Data Movement Move Copy Clear • Comparison • Greater Than • Less Than • Equal • Not Equal • Greater Than or Equal • Less Than or Equal • Math • Add • Subract • Multiply • Divide

  4. I:1 ADD ADD Source A N7:0 Source B N7:1 Dest N7:2 0 Math Instructions - ADD Source A + Source B = Dest N7:0 10 N7:1 5 N7:2 15 10 + 5 = 15

  5. I:1 ADD ADD Source A N7:0 Source B N7:1 Dest N7:1 0 Math Instructions - ADD Source A + Source B = Dest N7:0 1 N7:1 5 N7:1 6 1 + 5 = 6 Application: Running Total

  6. I:1 B3 ADD OSR ADD Source A N7:0 Source B N7:1 Dest N7:1 0 0 Math Instructions - ADD Source A + Source B = Dest N7:0 1 N7:1 5 N7:1 6 1 + 5 = 6 Application: Running Total NOTE: This instruction executes every scan that the rung is true, therefore use a One-Shot OSR.

  7. I:1 SUB SUBTRACT Source A N7:0 Source B N7:1 Dest N7:2 0 Math Instructions - SUBTRACT Source A - Source B = Dest N7:0 10 N7:1 5 N7:2 5 10 - 5 = 5

  8. I:1 MUL MULTIPLY Source A N7:0 Source B N7:1 Dest N7:2 0 Math Instructions - MULTIPLY Source A x Source B = Dest N7:0 10 N7:1 5 N7:2 50 10 x 5 = 50

  9. I:1 DIV DIVIDE Source A N7:0 Source B N7:1 Dest N7:2 0 Math Instructions - DIVIDE Source A ÷ Source B = Dest N7:0 10 N7:1 5 N7:2 2 10 ÷ 5 = 2 { S:13 0 remainder S:14 2 unrounded quotient Math Register

  10. I:1 DIV DIVIDE Source A N7:0 Source B N7:1 Dest N7:2 0 Math Instructions - DIVIDE Source A ÷ Source B = Dest N7:0 29 N7:1 10 N7:2 3 29 ÷ 10 = 2.9 { S:13 9 remainder S:14 2 unrounded quotient Math Register

  11. 0:3 GTR ( ) GREATER THAN Source A N7:0 Source B N7:1 0 Comparison Instructions > IF Source A > Source B THENTRUE ELSE FALSE 29 > 10 TRUE therefore Output is Energized N7:0 29 N7:1 10

  12. 0:3 LES ( ) LESS THAN Source A N7:0 Source B N7:1 0 Comparison Instructions < IF Source A < Source B THENTRUE ELSE FALSE 29 < 10 FALSE therefore Output is de-Energized N7:0 29 N7:1 10

  13. 0:3 EQU ( ) EQUAL Source A N7:0 Source B N7:1 0 Comparison Instructions = IF Source A = Source B THENTRUE ELSE FALSE 29 = 10 FALSE therefore Output is de-Energized N7:0 29 N7:1 10

  14. 0:3 NEQ ( ) NOT EQUAL Source A N7:0 Source B N7:1 0 Comparison Instructions ¹ IF Source A ¹ Source B THENTRUE ELSE FALSE 29 ¹ 10 TRUE therefore Output is Energized N7:0 29 N7:1 10

  15. 0:3 GEQ ( ) GRTR THAN OR EQUAL Source A N7:0 Source B N7:1 0 Comparison Instructions ³ IF Source A ³ Source B THENTRUE ELSE FALSE 29 ³ 10 TRUE therefore Output is Energized N7:0 29 N7:1 10

  16. 0:3 LEQ ( ) LESS THAN OR EQUAL Source A N7:0 Source B N7:1 0 Comparison Instructions £ IF Source A £ Source B THENTRUE ELSE FALSE 29 £ 10 FALSE therefore Output is de-Energized N7:0 29 N7:1 10

  17. I:1 MOV MOVE Source N7:0 Dest N7:1 0 Data Movement - Move Source Dest N7:0 50 N7:1 50

  18. I:1 COP COPY FILE Source #N7:0 Dest #N7:5 Length 4 0 Data Movement - Copy Source Dest } N7:0 10 N7:1 20 N7:2 30 N7:3 40 N7:4 N7:5 10 N7:6 20 N7:7 30 N7:8 40 }

  19. I:1 CLR CLEAR Dest N7:1 0 Data Movement - Clear Zero Dest N7:0 50 N7:1 0

  20. Advanced Instructions ANY QUESTIONS??? Data Movement Move Copy Clear • Comparison • Greater Than • Less Than • Equal • Not Equal • Greater Than or Equal • Less Than or Equal • Math • Add • Subract • Multiply • Divide

  21. File Type Timer Number (0-255) T4:0 4 Timers 15 14 13 File Number File contains 256 timers EN TT DN Word 0 Preset Value Word 1 Accumulated Value Word 2 Timer Addressing and Parameters Preset T4:0.PRE How long the timer should time for. Accumulated T4:0.ACC How long the timer has timed for already. Done T4:0/DN Set to “1” when accumulated value > preset value. Timer Timing T4:0/TT Set to “1” when accumulated value < preset value. Enable T4:0/EN Set to “1” when the rung containing the timer is true.

  22. M1 O:3/0 M1 O:3/0 Timers The Timer’s “done bit” turns the motor off after a 10 second time delay. Stop Motor Start Timer Done T4:0/DN I:1/1 O:3/0 I:1/0 ]/[ ]/[ ] [ ( ) ] [ TON (EN) ] [ TIMER ON DELAY Timer T4:0 Time Base 1.0 Preset 10 Accum 0 (DN)

  23. ON-OFF Selector Switch I:2/2 TON (EN) ] [ TIMER ON DELAY Timer T4:0 Time Base 1.0 Preset 10 Accum 0 (DN) Motor Timer Timing T4:0/TT O:3/0 ][ ( ) Timers The Timer’s “timing bit” turns the motor on for only 10 seconds.
