Data Sequence

## Data Sequence

Detects the chronological order in which data events occur on a timeline.

## Module Principle
Within the time interval between a start signal and an end signal, this module detects whether standard sequence strings appear in the specified order.

## Parameter Configuration Description

### Input Parameter Description:

*   **Max Count:** Starts counting from the first occurrence of the target string being detected.
*   **Valid Count:** The number of times the target string needs to appear within the range of the Max Count.

### Standard Sequence:

*   **Standard Sequence Input:** Enter the strings to be detected in the required order, separated by English commas. Multiple standard sequences can be added.

### Exception Sequence:

*   **Exception Sequence Input:** Enter strings representing potential abnormal orders, separated by English commas. Multiple exception sequences can be added. The module will report an NG (Not Good) status if an exception sequence is detected.

### Inspection Sequence:

*   **Inspection Sequence Description:** Displays the data flow for each string input port, used to view the order in which data events occur.

### Input Port Introduction:

*   **Start Signal:** A marker indicating the beginning of the sequence. It is an instantaneous pulse signal provided by an upstream port.
*   **End Signal:** A marker indicating the end of the sequence. It is an instantaneous pulse signal provided by an upstream port.
*   **Variable Ports:** These ports accept string type data, typically representing descriptions of the processes/steps to be detected. Multiple input ports are allowed.

## Output Description

*   **Run Result:** Indicates whether the timing detection is currently running.
*   **Total Status:** Stores the result for a data sequence interval. It retains the last detection result continuously.
*   **Detection Status:** The real-time result of the data sequence interval. It is an instantaneous state reflecting the current detection, generally used to output whether the current sequence check is OK or NG. There are four states:
    *   `-1`: Not Running
    *   `0`: NG (Failed)
    *   `1`: OK (Passed)
    *   `2`: In Progress
*   **Inspection Sequence:** The current detected sequence.
*   **Start Signal:** The run result of the start signal for the current frame.
*   **Stop Signal:** The run result of the end signal for the current frame.
*   **Port Info:** Indicates whether the input process/steps requiring detection have occurred.
