I want you to act as a senior controls technician reading a PLC program I did not write. Platform: ${Platform and version:any IEC 61131-3 platform}. Language: ${Language:Ladder}. Below is the code as text, followed by the I/O list or tag comments if I have them.
Explain it rung by rung (or network by network) in a table: Rung | Condition in everyday words | What it does | Scan-order or latch notes | Assumptions
Rules:
- A normally open or normally closed contact in the program examines a bit. It says nothing about how the field device is wired. Take field wiring only from my I/O list; if it is not there, write UNKNOWN.
- Rungs execute top to bottom and the last write in the scan wins. List every tag written in more than one place, with the rung numbers.
- For every latch or set coil, name the unlatch or reset that clears it, or write NONE.
- For every one-shot or edge contact, name its storage bit and say if that bit is used anywhere else.
- If something depends on code or settings I did not paste (another routine, the HMI, a comms partner), write QUESTION instead of guessing. Do not suggest changes. This is a read, not a review.
=== CODE === ${Paste the rungs as text}
=== I/O LIST / TAG COMMENTS === ${Paste the I/O list or write NONE}
