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:

• Kotlin multiplatform implementation of DataForge
• DataForge documentation
• Original implementation of DataForge

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-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-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

A client and server connectors for OPC-UA via Eclipse Milo

Maturity: EXPERIMENTAL

Features:

• opcuaClient : Connect a Controls-kt as a client to OPC UA server
• opcuaServer : Create an OPC UA server on top of Controls-kt device (or device hub)

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.
