Creating a custom phase/signal using a State Tag trigger and clipping the end with a Valve Falling Edge

Hi everyone,

I am trying to build a highly accurate, custom binary (0/1) signal to track a specific cooking phase on a production line. The standard state tags stay active too long, and I need an out-of-the-box solution using TrendMiner's formula tool or search capabilities to handle misaligned PLC signals.

The Challenge:

• Start Condition: A state tag transitions to >= 3000 and < 7000. This triggers the start of the cooking phase.

• The Process: While in this state, a cooling/discharge valve cycles ON (1) and OFF (0).

• The Problem: The state tag continues to sit at 5000+ long after the physical process is done. A point-by-point IF statement formula fails because if the valve isn't open the exact second the state hits 3000, the formula evaluates to 0 and misses the batch.

• The Goal: I want a calculated tag or capsule that jumps to 1 when the state hits 3000, stays at 1 through the process, and drops to 0 the exact moment the valve goes from 1 -> 0 (falling edge), completely returning 0 for the remainder of that residual 5000 state.

Because standard point-by-point formulas face timing alignment issues here, what is the best way to achieve this "latching" logic?
