Set Up Instruction Sequence

You can configure a collection of instructions to run at a predefined frequency. These instructions can come from different services and will be executed in the specified order based on the schedule you define.

To create an instruction sequence, follow the steps below:

  1. Navigate to Configuration ‣ Sequencing & Applications ‣ Scheduling Service from the menu.

  2. In the Scheduling Service pane, click the Create Instruction Sequence button (top right).

  3. In the Instruction Sequence dialog, proceed as follows:

    1. Define main sequence parameters:

      Field/Button

      Description

      Enabled

      Toggles the instruction sequence on or off.

      • ON: The scheduler will run at its next scheduled time.

      • OFF: The scheduler will skip execution until enabled.

      Sequence Name

      Enter a unique name for the instruction sequence.

      Use Cron

      If enabled, the schedule is defined using a Cron expression. Click the Cron hyperlink above the button to open the crontab.guru page, where you can build and copy a Cron expression. Example: 5 * * * * runs at the 5th minute of every hour; 50 0 * * * runs at 12:50 AM daily. Paste the expression into the Schedule field.

      Schedule

      Defines how often the sequence runs.

      • If Use Cron is enabled, paste the Cron value here.

      • If Use Cron is disabled, enter a numeric value (for example, 5) and select a Time Unit in the next field (for example, Minutes) to run the sequence at that interval (for example, every 5 minutes).

      Time Units

      Only shown if Use Cron is disabled. Select the unit of time (for example, Seconds, Minutes, Hours) that corresponds to the numeric value in the Schedule field.

    2. Click the Add Instruction button at the top of the dialog to add instructions to the sequence.

      • For each instruction, select the Service, Instruction, and any required parameters (similar to setting up a single instruction; see Set Up Single Instructions).

      • Set a Timeout value (in seconds). This defines how long the scheduler should wait for the instruction to complete before moving to the next one.

        Tip

        For instructions that must complete before the next one starts, set a timeout long enough to cover the expected duration. It’s safe to use large values - even days - since the scheduler proceeds as soon as the instruction finishes.

    3. Repeat the step above to add as many instructions as needed.

  4. Click Create to save the instruction sequence.

Result

The new instruction sequence appears in the Instruction Sequences tab of the Scheduling Service pane. If enabled, it will run according to the defined schedule.
