PLC Day 2 Vocab

3. The time required for one complete PLC scan cycle.
6. One horizontal line of logic in a ladder program.
7. One and only one output is placed near the right corner of the rung.
9. Location of each contact associated with a coil can be recorded by the right-hand rail near the coil.
12. Internal PLC tasks such as timers, counters, and diagnostics.
13. A circuit component that has resistance and consumes electric power.
14. An instruction that tells the PLC to skip part of the program and continue at another location.
15. A graphical programming language used to write PLC logic.
17. Input devices can be connected in series, parallel, or a combination.
18. A separate section of program logic that can be executed when needed.
20. AKA Latch - keeps the circuit in the “on” state after the start button has been released.
21. Input devices are placed near the left corner of the rung

1. The vertical lines representing power flow in a ladder diagram.
2. One complete execution (one full run) of a PLC program.
4. When the PLC executes the program continuously.
5. A single command in a PLC program.
6. While input devices can be represented multiple times in the relay logic diagram, each output device can only be represented once in the diagram.
8. Current in the relay logic diagram must flow from left to right.
10. All the input and output devices must be placed horizontally.
11. When you can write, edit, or load your program into the PLC
15. The TRUE (1) or FALSE (0) value stored in PLC memory.
16. Diagrams must be numbered and commented correctly.
19. Output devices cannot be connected in series.
