KPA Automation softPLC is a programming environment for developing PLC for real-time operation systems such as Linux, Xenomai, INtime or Windows. Focused on IEC 61131-3, KPA Automation softPLC technology is designed for all automation solutions, from machinery, controllers and drives manufacturers, to system integrators and machine builders. This technology is based on straton® PLC core and fulfils the 4 key requirements we apply to our products: Small, Smart, Simple and Speedy.

System compatibility

KPA Automation softPLC is a flexible, cross-platform and hardware-independent solution that can be integrated either on small platforms or on industrial PC platforms with or without operating systems.

Fieldbus configuration

KPA Automation softPLC includes an integrated fieldbus configuration tool for the following network I/Os and protocols:

  • OPC UA

    OPC UA stands for Open Platform Communications Unified Architecture and is the successor of the former OPC specifications. It is a standardized machine-to-machine protocol for industrial automation developed by the OPC Foundation.

    KPA Automation softPLC enables the creation and configuration of an OPC UA Server. It provides secure communication using digital certificates and data encryption.

    KPA Automation softPLC includes OPC UA Client, an OPC UA standard driver that allows to retrieve real-time values from OPC UA Servers to SCADA systems. OPC UA Client supports login and password authentication and monitors real-time data and events.

    Moreover, KPA Automation softPLC supports the OPC Alarms and Events specification for the transmission of alarms and events. When variables are declared in KPA Automation softPLC, it is possible to create conditions at which a user will receive notifications about changes in the state of variables.

  • Modbus

    KPA Automation softPLC includes fully integrated Modbus master (a client) and slave (a server) functions used to enable Modbus communication via a serial link or Ethernet.

  • MQTT

    KPA Automation softPLC provides support of MQTT, a lightweight publish/subscribe messaging protocol designed for M2M (machine to machine) telemetry in low bandwidth environments. It allows to send and receive data from the cloud. MQTT works on top of the TCP/IP protocol.

    At the core of MQTT are the MQTT broker and the MQTT client. The MQTT broker is a central server or middle ware that acts as an interface between publisher (a device that sends data to the broker) and subscriber (a device that receives data from the broker) and serves to collect the data from the publisher’s device and send it to the subscriber’s device.

    KPA Automation softPLC is used as the MQTT client that both publishes and subscribes messages.

  • Shared Memory

    KPA Automation softPLC includes a fully integrated configurator for virtual I/Os stored in a named memory space.

Integration with EtherCAT and Motion control

  • KPA EtherCAT Master to control EtherCAT network
  • KPA EtherCAT Studio configuration and diagnostic tool
  • KPA Motion Control to control single axis for point to point (P2P) according to PLCopen part 1, including gearing and camming options and 2D/3D coordinated motion according to PLCopen part 4
  • Motion Configuration Utility to generate configuration files

IEC61131-3 editors

The International Electrotechnical Commission (IEC) industry standard IEC61131-3 defines the main programming languages used by developers to create applications for PLC:

  • ST (Structured Text)
  • IL (Instruction List)
  • FBD (Function Block Diagram)
  • SFC (Sequential Function Chart)
  • LD (Ladder Diagram)

KPA Automation softPLC includes editors for ST, IL, FBD, SFC, LD programming languages, which provides advanced graphical features such as drag and drop for quick and easy element placement, syntax coloring and active tooltips for efficient input, keyboard shortcuts, object resizing, and other essential tools for building robust applications.

KPA Automation softPLC offers a program conversion option allowing an application to be translated into the chosen programming language in a few clicks.

Advanced debugging and monitoring tools

KPA Automation softPLC has a collection of features for making step by step debugging and includes a wizard that builds a monitoring application for the project.
