KAS Runtime

Kollmorgen Automation Suite RuntimeIn computer science, runtime (or run-time) describes the operation of a computer program, the duration of its execution, from beginning to termination (compare compile time). Within KAS, runtime also refers to the virtual machine that manage the program written in a computer language while it is running (commonly named the KAS Runtime) offers, in a single software package, the functionally of both a soft PLC"Programmable Logic Controller" A Programmable Logic Controller, PLC, or Programmable Controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events and a motion controller.

The KAS Runtime (virtual machine) is a high-performance deterministic environment designed to run on different hardware platforms ranging from low-cost programmable drives to high-end Programmable Automation Controllers. This gives machine builders all the flexibility when designing their machines.

KASsupports many configurations when integrating machines:

• Ranging from single-axis to more than 200 tightly coordinated axes
• With a centralized (Programmable Automation Controllers), distributed (Programmable Drives) or mixed (Programmable Automation Controllers + programmable drives) control architecture
• Running on a single or multiple controllers
• Communicating via EthernetEthernet is a large, diverse family of frame-based computer networking technologies that operate at many speeds for local area networks (LANs), EtherCATEtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs, Profinet, EtherNet/IP, ModbusModBus is a serial communications protocol and is now the most commonly available means of connecting industrial electronic devices. ModBus is often used to connect a supervisory computer with a remote terminal unit in supervisory control and data acquisition (SCADA) systems. Versions of the ModBus protocol exist for serial port and Ethernet (it is widely used with TCP/IP over Ethernet), or Profibus"Process Field Bus" Profibus is the most popular type of fieldbus (see Fieldbus entry in the glossary) used worldwide
• Using the high-performance Pipe Network or the standard PLCopenA vendor -and product- independent worldwide association active in Industrial Control and aiming at standardizing PLC file formats based on XML function blocks
• Controlling Kollmorgen's drives (AKD, some of the Servostar Sxxx drive family), AKM motors, and AKT terminals for I/Os products

The KAS Runtime can be used in the two different contexts:

• With a controller implementation (PCMM or PAC"Programmable Automation Controller" PAC is a compact controller that combines the features and capabilities of a PC-based control system with that of a typical programmable logic controller (PLC). A PAC thus provides not only the reliability of a PLC, but also the task flexibility and computing power of a PC. Additionally, because they function and communicate over popular network interface protocols, PACs are able to transfer data from the machines they control to other machines and components in a networked control system)
• With a master drive implementation (PDMM)

See Different Implementations for more details.
