Project description:
"I have a working CLICK PLC ladder program that reads three 4–20 mA analog inputs, averages each signal over 10 seconds, and then calculates a relative percentage between two of them. The math looks right on paper, yet live values are drifting about 10 % low. I suspect the issue sits in the averaging routine—possibly a formula or rung structure that’s pulling the result down.

Your tasks
• Pinpoint and fix the averaging logic so the displayed value aligns with the raw input (±1 %).
• Trim or eliminate the 1-second timers that are currently gating the output response. I want the system to settle in roughly 2–3 seconds instead of the current 10 seconds.
• Clean up any redundant rungs or tags for readability and future maintenance.
• Return a commented ladder file (CLICK PLC programming software) along with a brief change log outlining what was modified and why.

Scope and tools
– CLICK PLC (C0 series, AutomationDirect), standard ladder environment.
– Three analog input modules already configured; no hardware changes needed.
– Focus areas: averaging logic, output response, general housekeeping. No UI redesign or extra features required.

Acceptance criteria
1. Corrected average reads within 1 % of a manual calculation from live data.
2. Output percentage stabilizes within 3 seconds after a step change on any input.
3. Program downloads and runs without errors or watchdog trips on my end.

Timeline
I’ll supply the current program file immediately upon award. A 1–2 day turnaround is important, so please confirm you can start right away and deliver within that window." (client-provided description)
