Tag Config

This section explains how to configure tags for the Emulator Module so it generates emulated measurements for development, demos, and testing. 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:

<pattern>[optional_modifiers];param1;param2;...

Supported patterns

1) Sine curve

Generate a value that oscillates between min and max over a fixed period (seconds).

sinus;<min>;<max>;<periodSeconds>

Example

sinus;0;10;30

Generates a sine wave that varies from 0 to 10 with a 30-second period.

---

2) Step

Alternate between a series of numbers for specific durations (seconds), then repeat from the original number again (A).

step;<A>;<durationA>;<B>;<durationB>;...

Example

step;-10;5;10;15

Holds -10 for 5 seconds, then 10 for 15 seconds, and repeats.

---

3) Sequence

Loop through a fixed list of values in order, repeating when the end is reached.

sequence;<v1>;<v2>;<v3>;...;<vn>

Example

sequence;1;2;3;4;5

Emits 1, 2, 3, 4, 5, then starts over.

---

4) Random

Emit random numbers within a range.

random;<max>
random;<min>;<max>

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:

<pattern>[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.
