This manual introduces the OMRON P‑type programmable controllers, covering safety symbols, general and application precautions, and the operating environment. It emphasizes the importance of reading the safety sections before installing or operating the controller.
The document is organized into sections on hardware considerations, memory areas, ladder‑diagram programming, the full instruction set, program execution timing, debugging, and troubleshooting. Appendices list standard models, programming‑console operations, conversion tables, and other reference material.
DANGER indicates information that, if not heeded, could cause loss of life or serious injury; WARNING indicates possible loss of life or serious injury; Caution indicates possible minor injury or product damage.
Information about hardware indicators is provided in Section 3 Hardware Considerations, which describes the indicators used throughout the manual.
Ladder‑diagram programs are converted into mnemonic code and entered via the Programming Console, as explained in Section 7 Program Input, Debugging, and Execution.
