It follows the same overall tag structure used across modules and focuses on the parts relevant to the emulator’s data generation: ### Tag configuration properties used by the Emulator Module * **ModuleId**\ Set to `EmulatorModule`. * **Input.Source**\ Defines *what pattern* to generate and its parameters. This is the core of the emulator configuration (see syntax below). * **Input.SamplingRate**\ How often the emulator produces a measurement for the tag. The default sampling rate is 10 seconds. * **Input.MeasurementType**\ Desired output data type. Possible data types are "String", "Analog" or "Digital". > **Not used/ignored:** `Input.Endpoint` (no external endpoint is needed for the emulator). ### Input.Source syntax The emulator uses a simple, semicolon-separated syntax: ``` [optional_modifiers];param1;param2;... ``` #### Supported patterns **Sine curve** Generate a value that oscillates between `min` and `max` over a fixed period (seconds). ``` sinus;;; ``` **Example** ``` sinus;0;10;30 ``` Generates a sine wave that varies from 0 to 10 with a 30-second period. *** **Step** Alternate between a series of numbers for specific durations (seconds), then repeat from the original number again (A). ``` step;;;;;... ``` **Example** ``` step;-10;5;10;15 ``` Holds -10 for 5 seconds, then 10 for 15 seconds, and repeats. *** **Sequence** Loop through a fixed list of values in order, repeating when the end is reached. ``` sequence;;;;...; ``` **Example** ``` sequence;1;2;3;4;5 ``` Emits 1, 2, 3, 4, 5, then starts over. *** **Random** Emit random numbers within a range. ``` random; random;; ``` **Examples** ``` random;1000 (range 0..1000) random;100;200 (range 100..200) ``` *** #### Modifiers Attach modifiers in square brackets to the pattern name. Currently supported: **variance**. Adds noise by randomly adding or subtracting a random value each sample: ``` [variance=v];... ``` * `v` is an absolute value (same unit as the measurement). * Final output per sample: `output = base_value ± v` (random positive or negative value, with minimum -v and maximum v). **Example** ``` sinus[variance=0.3];0;10;30 ``` Generates a 0–10 sine wave over 30 s, then adds or subtracts a value between 0 and **0.3** to each produced measurement. --- # Agent Instructions This documentation is published with GitBook.
