Across
- 3. A PLC instruction used to create delays or measure elapsed time.
- 4. A graphical programming language resembling relay logic diagrams, used to program PLCs.
- 7. A PLC instruction used to turn an output device ON or OFF based on the logical conditions.
- 9. A PLC instruction used to check if an input or condition is ON (closed). If true, it allows the logic to proceed.
- 11. The sequence in which a PLC reads inputs, executes the control program, updates outputs, and performs housekeeping tasks.
- 13. A single line of logic in a ladder diagram, representing a control instruction.
- 14. Provides the necessary electrical power to the PLC system, converting AC voltage to the DC voltage required by the PLC components.
- 16. The "brain" of the PLC that executes the program and processes input/output data.
- 17. A section of PLC memory where inputs, outputs, and internal data are stored.
Down
- 1. A PLC instruction used to check if an input or condition is OFF (open). If true, it allows the logic to proceed.
- 2. A specific location in the PLC's memory where data or instructions are stored.
- 5. Hardware components of a PLC that interface with input and output devices in the system.
- 6. A PLC instruction used to count events, such as the number of items passing a sensor.
- 8. The smallest unit of data in a PLC, representing a binary state (0 or 1).
- 10. A signal or data received by the PLC from sensors, switches, or other devices to monitor system conditions.
- 12. An internal relay used within the PLC program to hold or maintain logic conditions.
- 15. A signal or data sent by the PLC to control devices such as motors, lights, or actuators.
