Controls.kt

Controls.kt (former DataForge-control) is a data acquisition framework (work in progress). It is based on DataForge, a software framework for automated data processing. This repository contains a prototype of API and simple implementation of a slow control system, including a demo.

Controls.kt uses some concepts and modules of DataForge, such as Meta (tree-like value structure).

To learn more about DataForge, please consult the following URLs:

DataForge-control is a Kotlin-multiplatform application. Asynchronous operations are implemented with kotlinx.coroutines library.

Features

Among other things, you can:

  • Describe devices and their properties.
  • Collect data from devices and execute arbitrary actions supported by a device.
  • Property values can be cached in the system and requested from devices as needed, asynchronously.
  • Connect devices to event bus via bidirectional message flows.

Modules

controls-constructor

A low-code constructor for composite devices simulation

Maturity: PROTOTYPE

controls-core

Core interfaces for building a device server

Maturity: EXPERIMENTAL

Features:

  • device : Device API with subscription (asynchronous and pseudo-synchronous properties)
  • deviceMessage : Specification for messages used to communicate between Controls-kt devices.
  • deviceHub : Grouping of devices into local tree-like hubs.
  • deviceSpec : Mechanics and type-safe builders for devices. Including separation of device specification and device state.
  • deviceManager : DataForge DI integration for devices. Includes device builders.
  • ports : Working with asynchronous data sending and receiving raw byte arrays

controls-jupyter

Maturity: EXPERIMENTAL

controls-magix

Magix service for binding controls devices (both as RPC client and server)

Maturity: EXPERIMENTAL

Features:

  • controlsMagix : Connect a DeviceManage with one or many devices to the Magix endpoint
  • DeviceClient : A remote connector to Controls-kt device via Magix

controls-modbus

A plugin for Controls-kt device server on top of modbus-rtu/modbus-tcp protocols

Maturity: EXPERIMENTAL

Features:

  • modbusRegistryMap : Type-safe modbus registry map. Allows to define both single-register and multi-register entries (using DataForge IO). Automatically checks consistency.
  • modbusProcessImage : Binding of slave (server) modbus device to Controls-kt device
  • modbusDevice : A device with additional methods to work with modbus registers.

controls-opcua

demo module

The demo includes a simple mock device with a few properties changing as sin and cos of the current time. The device is configurable via a simple TornadoFX-based control panel. You can run a demo by executing application/run Gradle task.

The graphs are displayed using plotly.kt library.

Templates

This feature required kotlin to be installed in your system. Read more

You may run gradle task generateKTStemplates instead of raw launch, but it will work slowly. Sample ./gradlew generateKTStemplates

This project supports generating of files from .ktstemplate. files. Current docs:

Using

  • Create file contains .ktstemplate in its name
  • Write variables before the first H* (starting with #) section
  • Launch kotlin ${thisscriptname} with required args

File sample

first = hello
second = world

# Sample

This is sample of $first $second

Will have next result:

# Sample

This is sample of hello world

Launch

This script accept next args:

[...paths] [--plain] [--recursive]

Where:

  • ...paths - Paths to the files-templates or folders with files-templates
  • --plain - will look only into the folders from paths
  • --recursive - (default) will look into the folders from paths and recursively in subfolders
